Evaluation Flashcards
Positives: Types of conformity (2)
- Asch (1951) places participants in a group of confederates who purposefully gave the same wrong answer, despite a 1% chance of getting the incorrect answer. In 33% of trails, participants conformed and also gave the wrong answer due to normative social influence.
- Jenness (1932) asked participants to individually guess how many beans were in the jar. He then put them in a group and found that their answers changed to match those around them. This is more likely to be informational social influence.
Negatives: Types of conformity (2)
- A third explanation (ingratiational conformity) has been suggested, and is similar to normative social influence, but group influence does not enter into the decision to conform. It is motivated by the need to impress or gain favour, rather than rejection).
- Dispositional factors such as personality traits may also impact if a person conforms e.g people with an internal locus of control are less likely to conform.
Negatives: Asch’s study (5)
- The study was conducted post-war, meaning people would have been more conformist than they are now, meaning the study lacks temporal validity
- The task given is unlikely to occur in real life (lacks mundane realism) and therefore cannot be generalised (ecological validity). In addition, conformity usually takes place in a social context.
- The study only included white American males, meaning it has gender and cultural bias. However, the study has been repeated with different samples, and results were similar.
- Participants volunteered to take part, meaning the study does not have population validity, and cannot be generalised
- Several ethical issues:
- Deception (however, this was necessary to avoid demand characteristics)
- Lack of informed consent
- Psychological harm
Negatives: Zimbardo (5)
- Highly unethical as prisoners were subjected to psychological harm (Prisoners showed extreme reactions such as crying, rage and acute anxiety. Zimbardo did not expect this.
- Zimbardo took role of prison warden. and became very involved and lost objectivity. Validity can be questioned
- Unrepresentative sample, cannot be generalised.
- Guards may have acted due to demand characteristics, meaning the study is not valid
- Some guards did not conform and were reluctant to resort to violence suggesting individuality plays a big role in conforming to social roles.
Positives: Milgram (1)
Cost benefit analysis shows it was worthwhile. 84% of participants said they were happy to have taken part and they had learned something important from the experiment
Negatives: Milgram (4)
- Deception, and therefore lack of informed consent. It was necessary to avoid demand characteristics and increase validity.
- Psychological harm (Milgram did not expect people to obey so this wasn’t predicted)
- Several participants who wished to withdraw were told they were not allowed, violating their right to withdraw.
- Unrepresentative sample (gender, culture bias)
Positives: Agentic State (1)
Participants in Milgram’s experiment were less likely to shock Mr Wallace if they were in the same room as him and can therefore see the consequences of their actions (no buffers). This supports the idea of agentic state, as being in close proximity to Mr Wallace and seeing him in pain would’ve prevented some participants from going into an agentic state.
Negatives: Agentic State (1)
Without buffers, people should not go into an agentic state and obey an order to harm someone. However, Mandel reported the case of Major, who was given orders to take a large group of Jewish people to the edge of the village and have them shot. Although the members of his battalion were given the chance to say no, many did not, and the massacre went ahead. This occurred despite the victims being in close proximity.
Positives: Legitimate Authority (2)
- Hofling (1966) found that nurses would obey a dangerous order from a doctor due to the hospital location. Nurses received a phone call from an unknown doctor (who was really an actor). He asked her to administer double the suggested dosage of a medicine to a patient. This broke hospital rules, and despite visual warnings on the bottle, and their own hospital knowledge, 95% of nurses carried out these instructions as doctors have legitimate authority.
- Bickman asked confederates to order passersby to pick some litter off the street or move away from a bus stop. The confederates were dressed as either a guard, milkman or just smart clothes . 90% of people obeyed the guard, but only 50% of people obeyed the person dressed in smart clothes. A person in a guard uniform is more likely to be perceived as a legitimate authority figure.
Positives: Authoritarian Personalities (2)
+ Miller (1975) found that people who scored high on the F Scale were more likely to obey an order to hold onto some electric wiring while working on an
arithmetic problem, compared to people who scored low it.
+ Altemeyer (1981) ordered participants to give themselves increasing levels of electric shocks when they made a mistake on a learning task. There was a
significant correlation between those willing to shock themselves and high scores on the F Scale.
Negatives: Authoritarian Personalities (3)
- Situational variables may be more important than dispositional ones. Milgram has conducted several variations of his original experiments with vastly
different results. Obedience was 100% when Mr Wallace made no noise (e.g. no screams or requests to leave). However, the obedience rate was 0% when there
were two authority figures who disagreed with each other (one wanted the teacher to continue, the other wanted them to stop). - Dispositional explanations cannot explain obedience in entire societies, because authoritarian personalities are not common. Far fewer than 65% of people have authoritarian personalities, so it cannot be the only explanation for the level of obedience found in the original Milgram (1963) study.
- It is possible that rather than authoritarian personality causing obedience, a lack of education causes an authoritarian personality AND obedience. Middendorp and Meleon (1990) have found that less educated people are more likely to have an authoritarian personality and Milgram (1974) found that participants with lower levels of education were more obedient.
Positives: Social Support theory (2)
- When the disobedient role model refused to shock Mr Wallace in Milgram’s experiment, only 10% of participants to deliver electric shocks up to 450V
- When a confederate acted like an ally in Asch’s study, conformity dropped from 33% to 5%
Negatives: Social Support Theory (1)
- In the original experiments on conformity and obedience, some participants were still able to resist social influence with no social support, so it is not a full explanation for resistance to social influence.
Positives: Internal locus of control (2)
- Oliner and Oliner found Germans who sheltered Jewish people in nazi germany were more likely to have an internal locus of control.
- Milgram got his participants to measure their locus of control with a questionnaire and found that the 35% of people who disobeyed were far more likely to have an internal locus of control than those who had obeyed.
Negatives: Internal locus of control (1)
Williams and Warchal found that conformers were less assertive than non-conformers, and the two groups did not score differently on a test to determine their locus of control, suggesting that assertiveness is more important than locus of control.
Positives: Moscovici’s Minority Influence
Moscovici told 172 female participants they were taking part in a colour perception task. They were placed in groups of 6 with other participants, 2 of which were confederates. They were shown 36 slides that were varying shades of blue and had to state out loud what colour the slides were. In the consistent condition, confederates said the slide was green in all 36 slides and swayed the minority 8.2% of the time. In the inconsistent condition, confederates said 24 of the slides were green and 12 were blue and participants only went along 1.25% of the time
Negatives: Moscovici’s Minority Influence (4)
- Gender bias: Only used women
- Cultural bias: All the participants were from America, and as a result the findings cannot be generalised to the rest of the population
- Most of the studies on minority influence are done in a lab setting. Participants in a lab are in an unknown environment with people they do not know, which would not happen in real life
- Ethical Issues: They deceived participants into the true nature of their experiment, therefore not getting their informed consent. Although, it was crucial to avoid demand characteristics and increase the validity.
Positive: Baddeley’s coding experiments (1)
This study is a lab experiment and reliability is high meaning it can easily be replicated.
Negatives: Baddeley’s coding experiments (1)
The experiment has low ecological validity, as the list of words participants needed to recall was artificial as was the lab setting.
Positives: Jacob’s capacity experiment (1)
Jacobs research was first to acknowledge that STM capacity gradually improves with age.
Negatives: Jacob’s STM capacity experiment (1)
This study was conducted a long time ago, so may not have been done to the same scientifically rigorous standard as research today, and therefore the validity can be questioned.
Positives: Peterson & Peterson STM duration experiment (1)
The research is said to have high control, using standardised procedures to make sure all participants experienced the same process. This included fixed timings, eliminating noise etc.
Negatives: Peterson & Peterson STM duration experiment (1)
The findings may have been caused by interference rather than STM having short duration. It is possible that earlier learn trigrams became confused with later ones.
Positives: Bahrick’s LTM duration experiment (1)
High ecological validity as material was more meaningful and relevant to everyday life
Negative: Bahrick’s LTM duration experiment (1)
It’s problematic to control extraneous variables such as people staying in touch after they left school or how many participants looked in their yearbook since leaving school.
Positives: MSM Neurobiological Evidence (2)
- Scoville attempted to treat HM’s epilepsy by removing several brain areas, including his hippocampus where LTM is stored. This resulted in HM being unable to code new long term memories, while his short term memory is unaffected. This supports the idea of separate LTM and STM.
- Shallice and Warrington reported the case of KF who was in a motorcycle accident, and had reduced STM capacity of only one or two digits, but his LTM was unaffected. This supports the idea of separate LTM and STM. However, KF had poor STM for verbal tasks, not visual tasks and this suggests there is different types of STM, unlike the multi store model of memory suggests. In addition, according to MSM, LTM are retrieved by STM, so if ST, is damaged, it should be difficult to retrieve LTM. However, KF was able to access LTM without any difficulty.
Positives: MSM Lab experiments (1)
Murdock presented participants with a long list of words to be recalled in any order, this was referred to as the free recall experiment. Words at the beginning and the end of the lists were recalled better than those in the middle. This is called serial position effect. Words at the beginning of the list are recalled because they have been constantly rehearsed and transferred to LTM (the primacy effect) while words at the end of the list are recalled because they are still in STM (the recency effect). This supports the idea of separate STM and LTM.
Negatives: MSM (2)
- The MSM is over simplified in assuming that there is only one type of STM and one type of LTM. Research studies indicate that there are several types of STM, such as one for verbal information (phonological loop) and another for non-verbal information (visuo-spatial sketchpad). Research also suggests that there are several types of LTM (episodic, semantic, procedural).
- Baddeley and Hitch claimed the MSM could not explain the ability to multi task, if there is only one type of STM, then multitasking would not be possible. However, people multitask all the time.
Positive: WMM Neurobiological evidence (1)
Shallice and Warrington reported the case of KF, who was in a motorbike accident, had poor STM for verbal words, but not visual words. This suggests there was more than one type of STM, as the WMM suggests. It shows we have a type of STM for verbal and visual tasks.
Positive: WMM Lab Experiments (2)
- Baddeley and hitch gave participants a dual task. they were asked to complete a reasoning task which uses the central executive, at the same time as a reading aloud task, which uses the phonological loop. Participants could do both tasks simultaneously very well, supporting the idea of separate STM compartments.
- Baddeley et al gave participants brief visual presentations of lists of words. These words were made up either of short words or long words. They were asked to recall the list immediately in the correct order. It was found that participants could recall more short words than long ones. Baddeley called this the word length affect and concluded that it supports the idea that the phonological loop can hold as many iteams as can be said in 1.5 to 2 seconds rather than being limited by 7 (+/-2) items as MSM argues.
Positive: WMM General (1)
The WMM has practical applications. It has improved understanding of how people learn to read and so helped psychologists to assist those with Dyslexia who struggle with reading.
Negative: WMM (1)
Several psychologists have criticised the WMM because they think the idea of a central executive is vague and untestable. Damasio presented the case of EVR who had a cerebral brain tumour removed. He had good reasoning skills which suggested his central executive was intact, but he could not make decisions, suggesting it was damaged. This case study strongly indicates that the central executive is more complicated than WMM claims.
Positive: Types of long term memory (3)
- Evidence has come from patients with amnesia. Typically, they are unable to store new episodic or semantic memories, but their procedural memory appears to be largely unaffected
- Scientific evidence captured from brain scans supports the view that there are different types of LTM. When asking patients to recall different types of information, different parts of the brain can be seen being used on the fMRI.
- Case studies offer support of different types of LTM e.g Cliver wearing damaged his hippocampus, so he has no episodic memory and cannot form new semantic memories, while his procedural memory is intact.
Negative: Types of long term memory (1)
- Research into different types of LTM have typically been conducted on individual patients. While case studies are highly detailed and provide a lot of information, they are isolated cases of the individual. It would be inaccurate and inappropriate to assume that everyones LTM is formed int the same way. Findings cannot be generalised.
Positives: Interference Theory (3)
- Underwood (1957) investigated proactive interference. He found that participants who learned ten lists of words could only recall 20% of the words from the first list the next day. Participants who learned one list of words recalled over 70% of the words the next day
- McGeoch and McDonald (1931) demonstrated retroactive interference. They gave participants lists of words that they had to learn until they could recall them with 100% accuracy. Participants then learned a new list. This list was either synonyms or antonyms of the original list. Participants given the list of synonyms had the worst recall. Learning two lists of words that have the same meaning would cause interference.
- This theory has practical applications. Students should be made aware of this theory so that they do not attempt to revise similar content/subjects at the same time, as this will make interference more likely to occur.
Negatives: Interference Theory (2)
- When interference occurs, the loss of information may only be temporary, therefore interference is not a true explanation for forgetting because the information is not actually over written and is still in LTM.
- Some psychologists argue that retrieval failure is a much better explanation of forgetting in everyday life than interference. This theory states that we forget when there are not enough retrieval cues to help us remember. Godden and Baddely (1975) got divers to learn and recall word lists on either dry land or underwater. Results showed that words learn and recalled in the same context were better remembered as there were retrieval cues in the environment to help them remember the words.
Positives: Retrieval Failure (4)
- Abernethy tested participants recall using a mixture of familiar instructors and teaching rooms. Participants were tested by a familiar instructor in a familiar room, performed the best because the instructor and room acted as retrieval cues.
- Gooden and Baddeley (1975) also demonstrated the importance of context-dependent cues. They asked divers to learn and recall work lists on dry land and underwater. Results showed that words learnt and recalled in the same context were better remembered as there were retrieval cues to help them remember the words.
- Darley et al (1973) showed the importance of state-dependent cues.They found that participants who hid money in a large warehouse while under the influence of cannabis were more likely to recall the hiding place when in a similar drugged state.
- Retrieval Failure has practical applications. Whenever possible students should learn/revise in the room, in which they will take their final exams.
Negatives: Retrieval Failure (1)
Baddeley (1997) argues that the influence of retrieval cues is not actually very strong. In real life, we often recall something in a different context to where we learnt it. For instance, students do not often take their GCSE examinations in the classroom where they learned the information they need for that exam.
Positives: Leading questions (1)
It is a lab experiment and therefore highly controlled. Reduced extraneous variables, increasing validity. It is also more reliable as it can be easily replicated.
Negatives: Leading questions (2)
- Questionable ecological validity. People who actually witness a car crash might have a stronger emotional connection to the event, and may not be as susceptible to leading questions
- Lacks population validity (45 American students). Students are less experienced drivers. Unable to generalise results. Older and more experienced drivers may be more accurate in their judgements of speeds and therefore less susceptible to leading questions.
