Q

conrad:

A

1964
-aim: to see how information is encoding in STM
-procedure:
-showed participants a random series of 6 consonants and asked them to remember them
-there were two conditions: acoustically similar (P,D,T) and acoustically dissimilar words (D,O)
-participants had to write them down in order
-findings: participants made frequent errors of recall, they also found out it hard to recall strings of letters that sounded similar. It was therefore concluded that STM is encoded phonologically

Q

Conrad: evaluation

A

Strength:
-the idea that STM is encoded acoustically is supported by Baddeley 1966
Weaknesses:
-lacks realism: the use of single letters does not compromise a reflection of the memory tasks we encounter in everday life
-other methods of encoding, such as visual (or even taste and smell) are also used

Q

baddeley:

A

1966
-aim: to test whether LTM was encoded acoustically or semantically
-procedure:
-participants were provided with different word lists that either sounded similar or meant similar things
-the 72 participants were recruited through opportunity sampling and were randomly allocated to four groups
-predictions:
-if participants could remember more similar-sounding words, LTM would be encoded acoustically
-on the contrary, if participants remembered more words with similar meanings, LTM would be encoded semantically
-the IV had two levels: 1. Acoustically similar words vs. Acoustically dissimilar words, 2. Semantically similar words vs, semantically dissimilar ones
-the DV was the score on a recall test of 10 words, participants had to recall the words in the order they were presented

Q

Baddeley 1966: different phases

A

-the learning phase was seperated from the testing phase by an interference test in which participants had to hear and write numbers
-in the testing phase, participants took part in a recall test
-for the recall test, participants needed to recall the words and the order in which they appeared
-this procedure was repeated four times, after the fourth trial, participants took a break and completed an unrelated interference task
-to their surprise, they were aked to recall the list of words again after the break

Q

Baddeley 1966: findings

A

-when calculating the results, the performance of the individuals in groups 1 and 2 was compared, as well as the performance of groups 3 and 4, seperately
-further, participants’ peformance on the 5th trial was analysed to test for forgetting
-the results indicated that:
-acoustically similar words were harder to recall than acoustically dissimilar words, remembering the words cap, hat, and sack is more difficult than remembering cow, dad and led
-semantically similar words were harder to recall than semantically dissimilar words, remembering the words big, large, and huge is more difficult than remembering hot, pen, and man
-when assessing STM, this is when comparing trials before the break, the worse performance was for the acoustically similar words
-performance was overall better on the semantic condition than on the acoustic one

Q

Baddeley 1966: conclusion

A

-the main conclusion that Baddeley drew from such results is that LTM is encoded semantically
-this comes from the fact that performance on the 5th condition was better for the semantic condition than for the acoustic one
-further, Baddeley (1966) concluded that STM is encoded acoustically
-this was deduced by the fact that performance on the short-term conditions (trials 1-3) was worse for semantically similar words

Q

Repeated measures design: definition and example study

A

-a type of experimental design where the same subjects are used for each treatment or condition
-example study:
-Loftus conducted a study that used a r.m.d to explore how the information presented after an avent can alter a person’s memory of that event
-participants views a car crash video and then asked misleading questions
-this design was appropiate since it allowed her to control indidivdual differences, measure how memories change over time and increase statistical power by comparing responses from the same participants under different conditions
-demonstrated how post-event information can alter people’s memories of an event

Q

Repeated measure design: advantages and disadvantages

A

advantages:
-increased statistical power -> reduces variability
-fewer participants needed -> more cost-effective
-control of condounding variables -> enhances internal validity by using same participants
-ability to track changes over time -> observes chamges within individuals across conditions
disadvantages:
-order effects (practice, fatigue) -> treatment order can influence results
-carryover effects -> previous treatments can affect responses in subsequent treatments
-participant attrition -> dropout can complicate results due to intertwined data

Q

Primary-Recency effect: seperate definitions

A

-primacy effect: the items at the start of the list are more likely to be transferred to our long-term memory due to repeated rehearsal
-recency effect: the items at the end of the list are still in short-term memory when recall is promptly

Q

Primary-Recency effect: information

A

-> the tendency to remember the first (primary) and last (rencency) items in a list, while forgetting those in the middle
-reasons: cognitive processess -> primacy and recency effect (other defs.) + memory -> primacy linked to long-term memory; recency linked to short-term memory
real life observations:
-shopping lists
-presentations
-job interviews
-exams
-everyday conversations
-application: understanding this effect can help structure information for imporved retention and recall

Q

Glanzer and Cunitz: findings

A

Immediate recall:
-participants showed both primacy and recency effects; they remembered the first and last items best
delayed recall:
-the recency effect dimisnhed significantly after a delay (due to the displacement of stm)
-the primacy effect remained relatively intact, supporting the idea that early items were stored in long-term memory

Q

what is the multi-store model of memory?

A

-the multi-store model of memory is the most well-known and influential model of memory, proposed by Atkinson and Shiffrin in 1968
-they saw memory as a flow of information through a system of interacting memory stores
-each store has a different purpose, and each varies in terms of capacity and duration

Q

evidence supporting a distinction between STM and LTM: KF

A

Shallice and Warrington (1970), The Case of KF:
- KF, a 28 year old man who sustained brain injuries after a motorcycle accident
-he had an impaired STM, working alongside a fully functioning LTM
-intact LTM -> he was able to learn new information and recall stored information
-reduced capacity STM -> he was only able to store a couple of bits or chunks of information rather than the normal 5-9 chunks

Q

evidence supporting a distinction between STM and LTM: HM

A

Milner (1966), The Case of HM:
-HM, a young man who suffered from epilepsy
-he underwent brain surgery to alleviate his epilepsy, which involved removing parts of his temporal lobes, including the hippocampus
-this operation left him with severe memory problems -> he could only recall events in his early life and was unable to recall events for about 10 years before the surgery. He could also not learn or retain new information
-however, he repeatedly read the same magazine without realising he had read it before and he was unable to recognise the psychologists who has spent long periods of time with him
-this suggests HM had a normal STM, but his LTM was detective and that it was no longer possible for him to lay down new memories in it, or if he could, he was unable to retrieve them

evidence supporting a distinction between STM and LTM: Drechman and Sahakian

A

1979
-administered a group of participants with a drug that blocks the action of acetylcholine in the brain, then gave them various memory tasks that tested either STM or LTM
-performance was compared with a control group
-found the experimental group performed at normal levels on the STM, but significantly more poorly on the LTM task
-suggesting STM and LTM work as a separate stored, involving different neurotransmitters

Q

limitations of the MSM: oversimplified

A

-human memory is extremely complex and it is highly unlikely that such a simple model could reflect this
-for example, the model doesn’t consider the different types of things we have to remember
-while it greatly emphasises the amount of information we can handle, it disregards the nature of the information
-everyday experience tells us that some things are easier to remember than others and this can simply be because we find it more interesting, relevant, funnier, etc.

Q

limitations of the MSM: the role of rehearsal

A

-there is considerable evidence that simple repetition is one of the least effective ways of passing on information
-there is also a strong evidence that long term memories can be formed without any apparent rehearsal
-Brown and Kulik (1977): they have described this type of remembering “flashbulb memory” which is where the insignificant details surrounding highly emotional and shocking events are imprinted directly into LTM without any rehearsal

Q

Independent groups design: explanation + ads and disads

A

-> is an experimental design whereby different participant are used for each experimental condition, the researcher exposes seperate sets of randomly allocated participants different
experimental
-typically, one of the two groups acts as a control group, this is because it doesn’t really experiment or receive the treatment whereas the other group is being tested in contrast to the first group
Advantages:
-simple and straightforward design
-less time consuming
-wide range of participants = more accurate findings
Disadvantages:
-differences in participants age, gender can alter results
-harder to control variables = less accurate findings
-altered data if a groups foes worse than expected

Q

what is the working memory model?

A

-by the early 1970s it was becoming clear that traditional information processing models, suchas the MSM, could not account for some of the findings from memory research
-it was clear that the STM store was far more complex than existing theories could account for
-Baddeley and Hitch (1974) contested the idea that STM was a single and entirely seperate store
-they referred to the case of KF who, while only having a digit span of two, could transfer new information to his LTM, suggesting that though there had been some disruption to STM, other aspects of his STM must have continued to function-there must be several components of STM

Q

the working memory model: actual model

A

-according to Baddeley and Hitch, working memory is a complex and flexible system comprised of several interacting components
-Central Executive
-Phonological loop- phonological store, articulatory control processes
-Visuo-spatial sketchpad- inner scribe, visual cache
-Episodic buffer

Q

the central executive:

A

-> is the supervisory system of working memory, itr controls and manages attention, planning, task switching, but has limited capacity
-it can process information from any sensory system (e.g. sight, sound) and coordinates the activity of other components in working memory
-it uses ‘slave systems’ like:
-phonologival loop (for verbal information)
-visuo-spatial sketchpad (for visual/spatial information)
-episodic buffer (for integrating information)
-these free up space for complex, allowing us to do more than one thing at a time, such as listening and watching
-the central executive is the most flexible but hardest to study, since it is less well understood compared to its slaves systems

phonological loop: Baddeley et al. study

-method: participants were shown lists of 5 words (either short, single-syllable words or longe, multi-syllabic words) and asked to recall all of them
-findings: short words were recalled better than long words
-conclusion: the phonological loop’s capacity is based on the time taken to say words, not the number of items (about 1.5 seconds) this is known as the word length effect

Q

episodic buffer:

A

-> is a general storage system that integrates information from the visuo-spatial sketchpad, phonological loop, central executive and long-term memory
-it was added to the working memeory model by Baddeley in 2000, as the original model couldn’t explain how people remember coherent chunks of information, like prose, better than unrelated words
-combines information across different parts of working memory and from long-term memory
-studies show that people with intact central executive function but amnesia could immediately recall prose but forgot it shortly after. This suggests the e.b. temporarily stored information before it fades
-helps explain why memory for coherent information (e.g., sentences) is better than for random words, it allows information to be structured and processed using both working and long-term memory

Q

Baddeley and Hitch study:

A

-aim: to test whether short-term memory (STM) has more than one component
-procedure: participants were given a six-digit number (e.g., 863492) to repeat out loud while also completing a reasoning task (e.g., judging sentences like “A follows B- AB” as true or false)
-hypothesis: if STM is limited to simple storage, doing two tasks at once should impair perfomance on the reasoning task
-findings: participants performed well on both tasks, although the reasoning task was slightly lower, errors were minimal
-conclusion: STM involves more than one component, as people can perform multiple tasks simultaneously if they use different parts of memory. Baddeley and Hitch saw STM as a “working memory” that actively processes information, rather than just storing it. They also viewed long-term memory (LTM) as a passive store accessed by STM when needed
-this study helped develop the Working Memory Model

Q

evaluating the working memory model:

A

-the WMM has been extremely influential and most cognitive psychologists now use the term working ememory in preference to the term STM
-it is a much more plausible model because it explains STM in terms of temporary storage and active processing
-it also incorporates verbal rehearsal as just one optional process within the articulatory loop, instead of being the sole modality and means of transferring information to LTM
-it attempts to explain how memory functions, rather than simply describing the structure of memory

Q

weaknesses of the working memory model:

A

-the central executive has not been precisley defined: for example, the term “process” is vague, and the central executive may be made up of several sub-components or even be part of a larger component itself in working memory
-this lack of a comprehensive explanation for each component of WMM draws doubts about the accurazy of its depiction of working memory
-Lieberman (1980) critisizes the working memory model as the visuospatial sketchpad (VSS) implies that all spatial information was first visual (they are linked)
-however, Lieberman points out that blind people have ecellent spatial awareness, although they have never had any visual information
-Lieberman argues that the VSS should be seperated into two different components: one visual information and one for spatial

Q

strengths of the working memory model:

A

-Shallice and Warrington’s study of KF provides support for the WMM because their findings show that KF had very poor STM recall for auditory stimuli but increased STM recall for visual stimuli
-this suggests that the components of memory which process auditory and visual stimuli are seperate (thus, STM is not a single, unified system), as described in the WMM through the phonological loop and VSS
-Studies of dual-task perfomance, where each participant must undertake a visual and verbal task simultaneously, shows decreased perfomance for such tasks and so supports. the idea that the central executive has a very limited processing capacity (as predicted by the WMM) and that the slave systems are in competition with each other for these tasks and resources

Q

more strengths of the working memory model:

A

-Baddeley et al. (1998) have presented evidence that the phonological loop, for exmaple, plays a key role in the development of reading, and that for children with dyslexia their phonological loop is not working properly
-while the phonological loop seems to be less crucial for fluent adult readers, is still has an important role in helping to comprehend complex text, it also helps in the learning of new vocabulary
-Turner and Engle (1989)
-Neuroscanning evidence, such as that provided by Braver et. al has demonstrated a positive correlation between an increasing cognitive load processed by the central executive (marked by increasing task difficulty) and increasing levels of activation in the prefrontal cortex
-this supports the idea that the central executive hs the role of allocating tasks to slave systems and has a limited processing capacity, as reflected by the increased brain activation levels, thus suggesting that the WMM is accurate in its mechanism of the central executive

Q

The effects of leading questions on the accuracy of EWT:

A

-memories witnesses create at the time of an event appear to be quite fragile and subject to distortion by things that happen after the event
-consequently, serious errors in EWT can occur
-it’s been found that witnesses who encounter inaccurate information after an event can absorb this into their memory, thus distorting the actual memory of the event -> Loftus (1992) calls this “misinformation acceptance”
-research algo suggests that there is a tendency for the misinformation effect to become stronger as the time between the witnessed event and recall of it becomes greater

-there was no broken headlight in the film
-17% of those asked about “the” broken headlight reported seeing one
-7% asked about “a” broken headlight reported seeing one
-those in the “the” condition -> gave fewer uncertain responses, such as “I don’t know” -> suggests they had greater confidence in memories for events that never occurred

Q

Loftus and Zanni (1975):

A

-using “the” implanted the idea that there was indeed broken glass, leading some participants to change their recall accordingly
-in practical terms -> suggests that the way questions are asked following a crime can lead to innacuracies in witness recall, and brings into question the reliability of EWT
-this misinformation effect through the use of leading questions has been replicated in many studies

42
Q

Loftus and Palmer:

A

1974
-showed 45 participants a film of a car accident
-following this they were asked to describe events as though they were witnesses
-they were then asked a serie of specific questions about events leading up to the accident
-one critical question concerned the speed of the car on impact
-one group was asked ‘How fast were the cars when they hit each other?’ Other groups of participants were asked the same question, but, in each case, the verb was changed to either ‘smashed’, ‘bumped’, ‘collided’ or ‘contacted’

43
Q

Loftus and Palmer: good things and bad

A

-because it was a controlled laboratory experiment, the study has been accused of being artificial, i.e. the conditions of testing do not resemble those in real life so therefore the behaviour of participants is not natural behaviour
-a film clip would not have the same emotional impact as witnessing a real-life accident, and because a witness would not be prepared to observe carefully (as they were in the experiment) it could be argued that their recall of a real accident would not be as complete
-there are a number of reasons why memories are affected by leading questions
-one possibility -> due to the constructive nature of LTM, leading questions actually change a witnesse’s perception of the event -> the storage of inaccurate memory
-whether or not accuracy of eyewitness memory is influences, storage or retrieval factors around the event itself can also influence recall

44
Q

Loftus:

A

1979
-gave participants a set of slides that showed a red purse being stolen from a handbag
-they were later given an account of the theft that included several errors, i.e. “the purse was brown”
-in a subsequent recall test, all but two of the participants resisted the misinformation about the colour of the purse, although they were influences by misinformation about less central elements of the theft
-Loftus concluded that memory for information that is particularly striking at the time of an event is less suspectible to misinformation acceptance than memory for more peripheral details
-another important factors appears to be -> the amount of anxiety caused by witnessing a crime
-it has long been established that states of high emotional arousal can influence memory functions, and a number of lab studies have demonstrated impaired memory in people who have witnessed particularly unpleasant and anxiety-inducing events

45
Q

What are extraneous variables?

A

-extraneous variables are factors or conditions that are not the focus of a study or experiment but could influence the outcome or results if not properly controlled
-these variables can introduce noise or bias into the experiment, making it harder to determine the true relationship between the independent variable (the one being manipulated) and the dependent variable (the outcome being measured)

46
Q

The importance of controlling extraneous variables:

A

-if extraneous variables are not controlled, they can become confounding variables, meaning they provide alternative explanations for the results
-proper control of these variables is crucial for the internal validity of an experiment, ensuring that any observed effect is due to the independent variable and not som other factor

47
Q

Possible extraneous variables in research:

A

-variations in individual memory capacity may influence how participants recall details of the event
-previous knowledge or experiences: some participants may have prior knowledge of the event or may have been involved in similar situations, which could affect their recall
-participant attention during the event: if participants are not paying equal attention to the event being recalled, this could affect recall
-social desirability bias: participants may alter their answers to conform to what they think is “right” answer or to please the researcher
-emotional state of participants: a participant’s mood or stress levels may influence how they recall details

48
Q

More possible extraneous variables:

A

-ambiguity in the even presented: if the event being shown to participants is ambiguous, this may influence recall
-question wording consistency: variations in how leading questions are phrased beyond the intended manipulation could introduce bias
-time delay between event and recall: the length of time between witnessing the event and being asked the leading questions may affect recall accuracy
-particpant’s age: age can affect memory recall, with younger and older participants possible recalling details differently
-environmental conditions: factors like lighting, sound, or other distractions in the environment may impact how well participants remember details

49
Q

Fisher et. Al:

A

1987
-over a 4 month period, they studied real interview conducted by experienced detectives in Florida
-found that witnesses were frequently bombarded with a series of brief, direct and close questions aimed to elicit
-the sequencing of these questions often seemed out of sync with the witnesses’ own mental representation of the event
-witnesses were often interrupted and not allowed to talk freely about their experiences
-Fisher felt these interruptions were unhelpful because they broke the concentration of the witnesses and also encouraged shorter, less details answers

50
Q

Geiselman et. Al:

A

1985
-> developed a technique to improve the accuracy of eyewitness recall during police investigations which they called cognitive interview
-context reinstatement (CR): mentally reinstate the context of the event, recall the scene, the weather, thoughts and feeling at the time
-report everything (RE): report every detail possible even if it seems trivial or irrelevant
-recall from a changed perspective (CP): try to describe the episode as it would have been seen from different points of view
-recall in reverse order (RO): change the order of recall so that the event is reported in different orders, moving backwards and forwards in time

51
Q

The cognitive interview:

A

-> designed to enhance retrieval of the original memory by providing extra cues that might help jog witnesses’ memory for more central details
-subsequent research led to a version of the technique called the enhanced cognitive interview
-after looking at current police practice through detailed analysis of taped interviews, Fisher et. Al(1987) suggested adding several extra features to a more structured process

52
Q

Support for the cognitive interview:

A

-Geiselman et. Al (1985): found that the cognitive interview resulted in more information being drawn from witnesses compared to other interview techniques
-Fisher et. Al (1989): also demonstrated the effectiveness of thecognitive interview technique in real police settings in Miami in the US
-they trained detectives to use the enhanced cognitive interview techniques with genuine crime witnesses and found that its use significantly increased the amount of information recalled
-Kebbell et.al (1999): carried out a survey of UK police officers and found that there was widespread use of cognitive interview
-Milne and Bull (2002): tested all cognitive interview procedures either singly or in combination
-they found that all 4 procedures snugly produced more recall from witnesses than standard interview techniques
-however the most effective combination appeared to be the use of CR and RE instructions, which is in line with that practising police officers had suspected

53
Q

Opposition to cognitive interview:

A

-Kohnken et.al (1999): found that witnesses questioned using the cognitive interview also recalled more incorrect information than those questioned using the standard questioning technique
-this is possibly because the cognitive interview procedure elicits more information overall than other procedures
For Kebbell: however, while officers found it useful, they expressed some concern about the amount of incorrect recall generated and the amount of time it took to complete an enhanced cognitive interview
-in practice, it seemed like officers were using the RE and CR instructions, but rarely the CP and RO

54
Q

Advantages and Disadvantages of the Cognitive interview:

A

Advantages:
-improved recall accuracy -> increases the amount of accurate info recalled
-reduces false memories
-widely applicable
Disadvantages:
-time intensive -> CI requires a longer time to conduct
-training demands
-inconsistent effectiveness

55
Q

Conformity and Internalisation:

A

-conformity: the tendency for an individual to align to their attitudes, beliefs, and behaviours with those of the people around them
-internalisation: the deepest type of conformity in which people change their beliefs permanently, so the beliefs become part of their way of seeing the world

56
Q

Compliance and Internalisation:

A

-Kerman (1958) argued that we can distinguish between different types of conformity
-compliance: the individual conforms publically but put privately disagrees with the view that they express
-internalisation: some views are adopted at a deeper, permanent level and they become part of the person’s own way of viewing the world

57
Q

Asch:

A

1951
-Asch believed conformity was a rational process in which people work out how to behave from other people’s actions
-he wanted to assess what would happen when an individual was confronted with a group who were plainly wrong in their judgement, to see if the individual would change their view to agree with the majority
-Asch recruited 123 male, white students and asked them to take part in a “task of visual perception”
-they were placed in groups of 7 to 9 and seated around a large table
-participants were shown two cards: the target line and then 3 more where 1 matched that one

58
Q

Asch 1951: techniques

A

-participants were asked to call out in turn which of the 3 comparison lines, A,B, or C matched the standard line in length
-each group carried out of a total of 18 trials
-to manipulate group pressure, the group was made of confederates who has been instructed to give the same wrong answer in 12 out of the 18 trials
-the real participant sat towards the end of the table, so they were exposed to the incorrect answer repeatedly before giving their own view
-ethics: as the trials progressed, participants became increasingly anxious and self-conscious regarding their answers, and some reported feeling of stress

59
Q

Asch 1951: findings

A

-the overall conformity rate was determined by how many times the participants gave the same wrong answer as the confederates
-overall conformity rate = 37%
-Asch also found individual differences in conformity:
-5% of the participants conformed on every critical trial, these could be seen as the most conformist
-25% remained completed independent, they gave the correct answer in all 12 critical trials and chose to stick to their viewpoint despite considerable group pressure
-most participants who conformed claimed they knew that the rest of the group was worng, but conformed because they didn’t want to stand out
-a small number wondered if their perceptions were inaccurate and doubted their eyes
-conclusion: people conform for two main reasons: because they want to fit in with group (normative influence) and because they believe the group is better informed than they are (informational influence)

60
Q

Asch’s study: evaluate

A

Positives:
-internal validity
-easily replicated
Negatives:
-reductionist
-biased sample
-population validity
-generalisability
-ethics: deception and protection from harm -> Back et al. (1963) found that participants in the Asch situation has greatly increased levels of autonomic arousal
-ecological validity

61
Q

Normative and Informational social influence: as key terms

A

-normative social influence: conformity based on the desire to be liked and accepted
-informational social influence: conformity based on the desire to do the right thing

62
Q

Explanations for conformity:

A

-the dual process dependency model (Deutsch and Gerard, 1955) identifies 2 reasons for conformity:
1. The desire to be accepted
2. The desire to be right

63
Q

Normative Social Influence: deep

A

-occurs when someone conforms because of their need to be accepted by and belong to a group
-this may be because they think belonging to the group is rewarding
-individuals may personally and privately continue to disagree but conform on the surface (compliance)
-normative social influence was the reason given for conforming by most of Asch’s participants

64
Q

Informational Social Influence: deep

A

-in some social situations, people may be unsure of how to behave or unclear as to how they think or feel about an issue
-as a result, they may conform because they don’t know what to do or say -> the drive for conformity is the desire to do the right thing
-in Asch’s experiment, a small minority of people doubted their own eyes and thus agreed with the confederates, showing informational social influence

65
Q

Criticisms of the Dual Process Dependency Model:

A

-it’s been criticise as it does not sufficiently acknowledge the importance of a sense of belonging to a group
-Hogg and Turner (1987) carried out a series of of experiments using a conformity task similar to Asch’s ‘line’ experiment, but varying the composition of the group from strangers to groups of friends
-participants were placed in booths so they could hear other people’s responses but could not see them
-Hogg and Turner found that conformity to a wrong anser only ocurred when people were among groups of friends
-Other studies have extended these findings, indicating that conformity to group norms persists even when group members are not present
-this shows how friends serve as a reference group, implying that conformity takes place due to group membership

66
Q

Variables affecting Conformity: based on Asch

A
  1. Unanimity: if the group’s unanimity is broken (e.g. a dissenter gives a different answer), conformity drops signficantly -> conformity fell to 5.5% when there was a dissenter, even if their answer was wrong which highlights how uninaimity strengthens social pressure
  2. Group Size: conformity increased as group size increased but leveled off at 3 confedertes (32%)
  3. Task Difficulty: increasing task difficulty (e.g. making lines more similar) increased conformity due to informational social influence-participants doubted heir judgement and relied on the group for guidance
67
Q

Key study: Allain, Midjord, Martin and Gabbert (2011) overview + procedure

A

-Allain et. al. (2011) investigated conformity using a memory task
-participants were informed that they would be working in pairs with another virtual participant
-they were instructed to memorise pictures of three household scenes:
1 picture was shown for half a minute
1 picture was shown for a full minute
1 picture was shown for 2 minutes

68
Q

Key study: Allain et. al. results

A

-half of the participants were told that their virtual partner would spend less time than them studying each picture
-half of the participants were told that their virtual partner would spend more time viewing the pictures
-paticipants were then provided with descriptions of the pictures from their ‘virtual partner’ containing true or false elements

69
Q

Key study: Allain et. al findings

A

-conformity to the partner’s response was most likely to happen when the picture had been viewed for 30 seconds, but only in the group who believed their virtual partner had studied the picture for longer
-in this case -> participants make their judgement to conform based on their knowledge of whose memory was more likely to be accurate
-Allan et. al.’s experiment shows how we adjust our behaviour based on the likelihood that we or other people are likely to make the correct judgement

70
Q

Jenness (1932): overview

A

1932
-Jenness conducted one of the earliest experiments examining conformity
-he used a glass bottle filled with 811 white beans
-his sample consisted of 101 Psychology students, who individually estimated how many beans were in the bottle
-participants were then divided into groups of 3 and asked to provide a group estimate through discussion
-following the discussion, participants were provided with another opportunity to individually estimate the number of beans, to see if they changed their original answer

71
Q

Jenness: results

A

-average estimate before: males- 790, females- 925
-average estimate after: males- 695, females- 878
-average change: males- 256, females- 382

72
Q

Jenness: findings

A

-Jenness found that nearly all participants changed their original answer, when they were provided with another opportunity to estimate the number of beans in the glass bottle
-on average male participants changed their answer by 256 beans
-on average female participants changed their answers by 382 beans
-these results demonstrate the power of conformity in an ambiguous situation and are likely to be the result of informational social influence
-the participants changed their answers because they believed the group estimate was more likely to be right than their own individual estimate

73
Q

replication of Asch’s line study: Perrin & Spencer (1980)

A

1980
background:
-some critics though the high levels of conformity found by Asch were a reflection of American 1950’s culture and told us more about the historical and cultural climate of the USA in the 1950s than they did about the phenomena of conformity
-in the 1950s America was very conservative, involved in an anti-communist-witch-hunt (which became known as McCarthyism) against anyone who was thought to hold sympathetic left-wing views
-Perrin and Spencer (1980) suggested that the Asch effect was a “child of its time”
-they carried out an exact replication of the original Asch experiment using engineering, mathematics, and chemistry students as subjects

74
Q

Perrin & Spencer (1980): results

A

-they found that in only 1/396 trials did an observer join the majority
-Perrin and Spencer argue that a cultural change has taken place in the value placed on conformity and obedience and the position of students
-in America in the 1950s, students were unobstrusive members of society, whereas now, they occupy a free questioning role
-however, one problem in comparing this study with Asch is that very different types of participants are used
-Perrin and Spencer used science and egineering students who might be expected to be more independent by training when it came to making perceptual judgements

75
Q

further studies: Asch 1952, 1956

A

-in further trials, Asch (152, 1956) changed the procedure (i.e. the independent variables) to investigate which situational factors influenced the level of confomity (dependent variable)

76
Q

Asch 1952,1956: group size

A

-Asch found that group size influenced whether subjects conformed
-the bigger the majority group (not of confederates), the more poeple conformed, but only up to a certain point
-with one person (i.e. confederate) in the group conformity was 3%
-with two others it increased to 13%
-with three or more it was 32% (or 1/3)
-optimum conformity effects (32%) were found with a majority of 3
-increasing the size of the majority byond three did not increase the levels of conformity found
-Brown and Byrne (1997) suggest that people might suspect collusion if the majority rises beyond 3 or 4
-according to Hogg & Vaughan (1995), the most robust finding is that conformity reaches its full extent with 3-5 person majority, with additional members having little effect

77
Q

Asch 1952, 1956: unanimity

A

-Asch investigated the importance of unanimity by positioning a confederate just before the real participant around the table and instructing them to give the correct answer on the critical trials
-he found that conformity dropped drastically to 5.5%
Asch identified two explanations for why this might occur:
1) the dissenter supports the participant, increasing the participant’s confidence that they are correct
2) the dissenter breaks the united front of the group
-the existence of a different viewpoint is enough to give participants confidence to pursue their own answer, regardless of whether they received support for their view or not

78
Q

Asch 1952, 1956: task difficulty

A

-task difficulty is another influence on conformity, in Asch’s original experiment, the task of judging line length was extremely easy
-Asch manipulated this by making the difference lengths much smaller and found an increase in conformity
This was also found in a study by Rosander (2012):
-investigated conformity in around 1,000 members of various internet communities (e.g. Facebook, Twitter, etc.)
-participants were asked questions about general knowledge and logic
-half participants were given incorrect answers via confederates
-results showed that conformity to incorrect answers increased with more difficult questions

79
Q

Milgram 1963: context

A

1963
-Milgram wanted to investigate obdeince to authority, he wondered to what extent ordinary people could do extraordinary things
-Milgram believed that obedience to authority and “following the rules” was a way of maintaining stability in society
-however, when we follow these rules, we surrender some of free will
-agentic theory is a social psychological theory that explains how individuals act in situations when they are expected to make decisions on behalf of another person
-according to Agency Theory, people can experience 2 different states of agency: the Agentic State and the Autonomous State

80
Q

Agentic State:

A

-this is an explanation of obedience offered by Milgram and it is where an individual carries out the orders of an authority figure, acting as their agent
-the shift from autonomy to ‘agency’ is reffered to as the ‘agentic shift’
-according to Agency Theory, obedience is a natural human impulse
-Milgram’s research therefore highlights the problems that can occur from destructive obedience
-in WW2 obedience resulted in negative social change - the Nazis obeyed orders and as a result, Hitler managed to get what he wanted, which was not what the majority of people wanted
-such research gives an insight into why people were so willing to kill innocent people simply when told to, and so highlights how we can all easily be victims to such pressures
-a general awareness of the power of such influences is useful in establishing social order and moral behaviours

81
Q

Milgram 1963: aim

A

-the study was designed to measure how far participants would go in obeying an authority figure who instructed them to perform acts that conflicted with their personal conscience
-specifically, it aimed to quantify the level of shock participants were willing to administer to another person under the guise of a learning experiment when instructed to do so by an authority figure
-Milgram also investigated the conditions under which people obey or disobey authority and the psychological mechanisms (reasons) behind obedience and disobedience

82
Q

Milgram 1963: procedure

A

random selection of participants: 40 male volunteers, aged 20 to 50 years, all American
-a participant was given the role of a “teacher” and a cofederate given the role of a “learner”, this was decided through a random allocation
-participants had to ask the confederates a series of questions
-whenever the confederate got an answer wrong, the participant had to dive him an electric shock, even when no answer was given
-the electric shocks increased by 15 volts at a time, up to 450V, 330 V was marked as lethal
-at 180V the learner would complain of a weak heart, at 300V he would bang on the wall and demand to leave, at 315V he became silent to give the illusion that he was unconscious or even dead
-participants thought the shocks were real when in fact no real shocks were administered, the confederate was acting
-the shocks were falsey demonstrated to be real prior to the start of the study
-participants were assessed on how many volts they were willing to shock the confederate with
-the experimenters role was to give a series of orders or prods when the participant refused to administer a shock, which increased in terms of demandingness every time the participant refused
-the same 4 prods were used each time when participants refused to administer shocks

83
Q

Milgram 1963: findings

A

-during the trials, all of the participants went up yo at least 300 volts, 5 of the participants (12.5%) stopped at 300V when the first signs of distress by the learner appeared
-35 (65%) went up to the highest levels of 450V, a result that Milgram didn’t anticipate
-participants also showed intense signs of tension and distress including nervous laughing fits, groaning, ‘digging fingernails into their flesh’ and convulsions, for 1 participant the experiment had to be cut short because they started having a seizure
-Milgram’s experiment indicates that it is normal to obey legitimate authority figures, even if the order goes against our conscience
-after the study, all the participants were told of the hoax and debriefed, including meeting the ‘learner’ again

84
Q

Milgram 1963: conclusion

A

-all of the study participants obeyed the authority figure when asked to go against their better judgement rather than refuse to proceed
-although they were met with resistance, all study participants had been informed at the start that they could stop the experiment at any point, Milgram argued that it’s normal for humans to give in to destructive obedience when pressured
-what was surprising about Milgram’s experiment was how easy it was to get people to be destructive- participants obeyed even in the absence of force or threat
-Milgram’s results speak against the idea that particular groups of people are more prone to obedience than others

85
Q

Milgram 1963: evaluation

A

Strengths:
-validity
-reliability
-operationalisation of human behaviour
Weaknesses:
-ecological validity
-debate about internal validity
-biased sample
-ethical issues

86
Q

Milgram: validity

A

-the control of variables through set prods, a unified setting, and procedure means that it’s more likely that the results of Milgram’s experiment produced internally valid results
-this is a strength of laboratory experiments in general; because if the controlled environment, it is more likely that the researcher can measure what they set out to measure

87
Q

Milgram: reliability

A

-with the shock experiment, Milgram was able to reproduce a similar result with 40 different participants
-after his first experiment, he also went on to test many different variables that could influence obedience

88
Q

Milgram: operationalism of human behaviour

A

-in psychology, operationalisation means being able to measure invisible human behaviour in numbers
-it’s a major part of making psychology a legitimate science that can produce objective results
-this allows for comparison of people with each other and statistical analysis as well as comparison with other similar experiments that happen in other places in the world and even in the future
-by creating a fake shocking apparatus, Milgram was able to measure in numbers to which extent humans would obey authority

89
Q

Milgram: external validity

A

-there is some debate about whether Milgram’s obedience study has extrenal validity
-even though conditions were strictly controlled, the laboratory experiment is an artifical situation and this might factor into how participants behaved
-Orne and Holland (1968) thought that the participants might have guessed that they were not really harming anyone, this casts doubt on whether the same behaviour would be seen in real life

90
Q

Milgram: the debated about internal validity

A

-the internal validity was questioned by Perry (2012) examined the tapes of the experiment and noted that many participants expressed doubts that the shocks were real to the ‘experimenter’
-this might indicate that what was displayed in the experiment was not genuine behaviour but rather the effect of unconscious or conscious influence by the researchers

91
Q

Milgram: biased sample

A

-the sample was made up exclusively of American men, so it’s not clear whether the same results would be obtained using other gender groups or cultures
-to investigate this, Burger (2009) partially replicated the original experiment using a mixed male and female American sample with diverse ethic backgrounds and a broader age range, the results were similar to Milgram’s showing that gender, ethnic background, and age might not be contributing factors to obedience
-Shonab’s (1987) replication in Jordan showed remarkable differences in that Jordanian students were significantly more likely to obey across the board, this raises the question of whether there is a difference in level of obedience in different cultures

92
Q

Milgram: ethical issues:

A

-although the participants were debriefed and 83.7% of them went away from the experiment satisfied, the experiment itself was ethically problematic
-using deception in a study means that the participants can’t give their full consent as they don’t know what they’re agreeing to
-also, keeping participants in an experiment againts their will is a violation of their autonomy, but Milgram’s 4 stocks answers (prods) meant that the participants were denied their right to leave
-it is the researcher’s responsibility to ensure that no harm comes to the participants, but in this study, the signs of mental distress were at times extreme

93
Q

studying obedience within ethical frameworks:

A

-it is important to note that without deception, it would have been very difficult for Milgram to study obedience
-in the years following Milgram’s research, ethical guideline were introduces by the British Psychology Society (BPS) and the American Psychology Association (APA)
-these guidelines state that participants in research should be protected from harm and deception should only be used if absolutely necessary

94
Q

factors that affect obedience: proximity

A

-participants obeyed more when the experimenter was in the same room i.e. 62.5%
-this was reduced to 40% when the experimenter and participant were in seperate rooms, and reduced to a further 30% in the touch proximity condition i.e. where the teacher was instructed by the experimenter to forcibly place the participant’s hand on the electric plate

95
Q

factors that affect obedience: location

A

-participants obeyed more when the study was conducted at a prestigious university i.e. Yale
-this is because the prestige of such a location demands obedience and also may increase the trust that the participant places in the integrity of the researhcers and their experiments

96
Q

factors that affect obdedience: uniform

A

-participants obeyed more when the experimenter wore a la coat
-a person is more likely to obey someone wearing a uniform as it gives them a higher status and a greater sense of legitimacy
-it was found that obedience was much higher when the experimenter wore a lab coat as opposed to normal clothes
-however, demand characteristics were particularly evident in this condition, with even Milgram admitting that many participants could see them through this deception

97
Q

Run Down Office Block: experiment 10

A

-Milgram aimed to see whether how the level of prestige of a location would affect obedience levels
-Milgram paid volunteer participants to take part in a study conducted by research associates of Bridgeport
-a rigged draw used to allocate the participant to the role of teacher and confederate to the role of learner
-the original apparatus from Milgram’s (1963) experiment was used such as the shock generator which went from 15V to 450V, obedience in the rundown office block dropped to 47.5%
-Milgram concluded that reduced prestige of a location led to fewer participants obeying
Evaluation:
-experiment 10 took place in a more realistic setting of an office block in Bridgeport, which increases the ecological validity of the research for completing an obedience task
-it was a more natural setting for testing obedience because the participants are likely to have been in an office before
-the study in Bridgeport used Milgram’s standarised procedure, for example, the verbal prods, which increases the reliability of the obedience study as it can be replicated

98
Q

Telephonic Instructions: experiment 7

A

-Milgram aimed to see whether the physical distance between the experimenter and the teacher would affect obedience levels
-when instructions were given over the telephone, obedience dropped to 22.5%
-Milgram concluded that reduced proximity of the experimenter led to fewer participants obeying
Evaluation:
-one weakness in Milgram’s Experiment 7 is that he placed participants in an artificial laboratory setting to answer the telephone which is not an ecologically valid setting for measuring everyday obedience to an authority figure giving instructions over the telephone

99
Q

Ordinary man gives orders: experiment 13

A

-in experiment 13 only 20% of participants gave the maximum 450V shock
-obedience level dropped from 65% in Milgram’s original experiment to 20%, this demonstrated the dramatic power of uniform
Evaluation:
-the procedure was standardised so could be replicated to test for reliability
-the accompliance was always given the task of recording times at the experimenter’s desk and the experimenter was always called away by a rigged phone call
-the participant was deceived so the study has questionable ethics
-the experimenter and ordinary man were accomplices of the study which the participant was not made aware of so way lied to

100
Q

Autonomous State:

A

-the autonomous state is a state of agency in agency theory where individuals act on their own behalf and take responsibility for the consequences of their actions
-someone will follow their own personal moral code of conduct, rather than deferring responsibility to someone else
-participants who dropped out of the study had made the shift back from agentic state to autonomous state as they realised they were in charge of making their own decisions

101
Q
A
