Q

Abernethy (1940)

A

arranged for a group of students to be tested weekly prior to a certain course beginning. Some were tested in their classroom by their teacher, some in their classroom by a different teacher, some in a different classroom with their teacher and some in a different classroom with a different teacher. The group tested in their classroom by their teacher did best

Q

Baddeley and Hinch (1970)

A

participants were asked to perform two tasks simultaneously, either two tasks involving the articulatory loop or one task involving the articulatory loop and one taks involving both the central executive and articulatory loop. They found that participants did better in tasks that required separate parts of the brain, which supports the working model of memory

Q

Baddeley and Hitch (1977)

A

involved asking rugby players to try and remember the names of teams they had played so far in the season, week by week. Most of the players had missed at least some games. The results clearly showed that accurate recall did not depend on how long ago the matches took place, more important was the number of games played in the meantime. However, Baddeley himself stated that the tasks given to participants were too close together and in real life, the events would be more spaced out, which might affect results

Q

Bransford and Johnson Experiment

A

a number of experiments which illustrated the role of schemata in our understanding and recall of information. I one experiment, participants were read a passage and asked to recall it as accurately as possible. Half were given a title and half were not. The half that were given a title remembered the passage better, as the title provides a schema so information can be appropriately stored and recalled more easily

Carter and Cassaday (1998)

A

looked at the effect of anti-histamines, giving anti-histamines to their participants. They had a mild sedative effect and this created a psychological state different from the normal. The participants had to learn lists of words and then recall them. In conditions where there was a mismatch between internal state at learning and recall, there was more forgetting

Concept Formation

A

the process of forming concepts, for example, ‘animal’ is a concept that involves sub-concepts such as ‘birds’, ‘fish’ or ‘mammals’, which can then be further divided. It is easier to remember things if you can make links between concepts

Q

Encoding Specificity Principle

A

in 1983, Tulving’s research into retrieval failure discovered a consistent pattern to the findings. He summarised this pattern in what he called the ESP. This states that if a cue is to help us to recall information then it has to be present at encoding and retrieval

Q

Episodic Buffer

A

was added as Baddeley realised the model needed a more general store. This has a limited capacity of four chunks and integrates information from all other areas

41
Q

Episodic Memory

A

refers to the ability to recall episodes from your life, for example, your first day of school. These memories are complex, as they allow you to remember events exactly as they were and the memory will include several elements all interwoven into one memory. These require conscious effort to recall

42
Q

Eyewitness Testimony

A

evidence provided by those recalling an event who were present when the event took place

43
Q

Anxiety

A

a factor affecting eyewitness testimony, research suggests that frightening situations may affect recall because, as well as weapon focus, stress itself may have a negative effect on performance

44
Q

Misleading Information/Leading Questions

A

information that suggests a desired response

45
Q

Post-Event Discussion

A

information added to a memory after the event has occurred. For example, when more than one witness discuss a crime they have both seen, their testimonies become contaminated because they combine information from their own memory with other witnesses’ views. This can make them ore inaccurate

46
Q

Fisher and Geiselman (1992)

A

by reviewing memory literature, which showed that people remember things better if they are provided with retrieval cues, they devised an interview technique with four components, with the aim of improving effectiveness of questioning witnesses in police films

47
Q

Fisher et al (1987)

A

developed additional elements of the cognitive interview. The enhanced cognitive interview focused on the social dynamics of the interaction, eye contact, minimising distractions, reducing anxiety, open-ended questions and slow speech

48
Q

Fuzzy Concept

A

where a concept can vary depending on context or conditions, instead of being fixed

49
Q

Gabbert et al (2003)

A

participants were set up in pairs. Each pair watched a video of the same crime but from different perspectives. They were then paired up and discussed the crime. 71% of participants mistakenly recalled aspects of the event they could only have picked up from the discussion

50
Q

George Mandler Experiment 1967

A

Mandler suggested that by organising information, you learn it even though you are not making any effort to memorise it. Mandler carried out an experiment where two groups of participants were each given a pack of one hundred cards, each with a word printed on it. Both groups were told to organised the cards into groups, and were allowed to have several goes at organising them. The only difference was that participants of the first group were told to try memorising the words whilst organising them. When both groups were later tested on how many words they remembered, there was little difference between the groups

51
Q

Ginet and Verkampt (2007)

A

an example of anxiety affecting recall. Fake electrodes were placed on their bodies and participants were told if they misremembered the answers they would be shocked

52
Q

Glanzer and Cunitz (1966)

A

Glanzer and Cunitz showed participants a list of 20 words. They were presented one at a tie and then asked to recall them. They found that people have a tendency to remember words at the beginning and at the end of a list

53
Q

Gooden and Baddeley (1975)

A

carried out a study of deep sea divers working underwater. Divers learned a list of words either underwater or on land, and were then asked to recall the words either underwater or on land. Accurate recall was 40% lower in non-matching conditions. However, the groups who learned in different environments were disrupted so this could have influenced their recall

54
Q

Goodwin (1969)

A

repeated Carter and Cassaday’s experiment but instead of using anti-histamines used alcohol. Found that people who were sober when learning and sober when tested did best, then people who were drunk when learning and drunk when recalling

55
Q

Henry Molaison

A

the most studied man in the history of psychology, had his hippocampus removed in order to cure his epilepsy and ended up losing his short-term memory

56
Q

Inner Scribe

A

used for spatial relations

57
Q

Interference Theory

A

a theory for forgetting in long-term memory

58
Q

Jean Piaget

A

a Swiss psychologist who died in 1980 after spending over 50 years investigating how children develop thinking and cognitive skills. He proposed they did this by developing schemata, which are built up from the experience of the world, first came up with word schema

59
Q

Kebbel and Wagstaff (1996)

A

the police are reluctant to use CI because it takes more time than a standard interview. It also requires more training than the police have time to deliver, however CI techniques vary between police forces, so it is difficult to evaluate its effectiveness fully

60
Q

Kohnken et al (1999)

A

a meta-analysis of 53 studies found on average a 34% increase in the correct amount of information generated in the cognitive interview. However, most of these studies were done on university students. As well as correct information being increased, the CI also increases incorrect information. A 61% increase in the false positives were found when ECI was used compared to a standard interview

61
Q

Loci Method

A

a method of memorising a list where a person imagines each of the objects on the list somewhere in a known location, using mental images

62
Q

Loftus (1975)

A

concluded that it is mainly peripheral information that is unreliable and can be tampered with. Participants were shown a man stealing a large red wallet. Even after reading an account where the wallet was described as brown, only two percent of participants changed their testimony

63
Q

Loftus (1994)

A

each participant was given summaries of four events from their childhood, three true ones based on accounts from their parents and one fake account of getting lost in a shopping centre. After being interviewed a few weeks later, 25% now reported clear memories of being lost in a shopping centre as a child

64
Q

Loftus and Palmer (1974)

A

asked people to estimate the speed of cars using different forms of questions. They questions would be worded differently, using words such as “smashed”, “collided”, “bumped”, “hit” and “contacted”. On average those who heard the word “smashed” overestimated the speed the most and those who heard the word “contacted” underestimated the speed the most

65
Q

Loftus and Pickrell (2003)

A

participants were exposed to fake adverts of Bugs Bunny at Disneyland despite the fact Bugs Bunny is not a Disney creation. Afterwards, roughly a third remembered shaking hands with Bugs Bunny at Disneyland even though it never happened

66
Q

Loftus et al (1987)

A

participants heard a discussion in another room and then saw a man emerge either holding a pen or a knife. When asked to identify the man from 50 photos, 49% remembered the pen holder and 33% remembered the knife holder, suggesting that the weapon distracted attention and explaining why witnesses may have poor memory of violent crime

67
Q

Mello and Fisher (1996)

A

when CI and normal interview techniques were tested on both 72-year-olds’ and 22-year-olds’ memory, CI was found to be better for both, but was found to be a significant advantage for the elderly

68
Q

Memon and Yarmey (1999)

A

77 undergraduates were instructed to act as kidnap victims and heard taped instructions given by mock abductors. Two days later, witnesses recall was tested using either CI or a structured interview. Participants then rated the abductors’ voice for nine speech characteristics and attempt to identify his voice from an audiotaped lineup. It concluded that the success of CI is better explained through its influence on social components of interviewing rather than the free recall aspect

69
Q

Miles and Hardman (1998)

A

found that people who learnt a list of words whilst exercising on an exercise bike remembered better than those who learnt at rest

70
Q

Milne and Bull (2002)

A

this laboratory experiment found that a combination of ‘report everything’ and ‘mental reinstatement’ significantly increased participants’ recall, however, this study lacked ecological validity

71
Q

Mind Mapping

A

a method of memorising things that involves making links between concepts

72
Q

Non-Declarative Memory

A

memories that are consciously recalled; procedural memories

73
Q

Overgeneralising

A

young children often do this when forming concepts, for example, they may get dogs and cats muddled because their dog concept involves fur, four legs and a tail. They may not be able to identify a dog if it doesn’t fit their concept

74
Q

Patient KF

A

suffered brain damage in a motorbike accident which damaged his phonological loop but his visuo-spatial sketchpad remained intact

75
Q

Peters (1988)

A

participants attending a local health clinic for injections met with a researcher and nurse for equal lengths of time and were asked to identify them from photos a week later. They recalled the researcher better than the nurse, suggesting that the anxiety of having an injection had an impact on their memory.

76
Q

Primacy Effect

A

the tendency fore people to remember the first five or so words from the beginning of a list

77
Q

Proactive Interference

A

occurs when an older memory interferes with a newer memory

78
Q

Procedural Memory

A

memory store for actions or skills, such as touch-typing. These memories can be recalled without conscious awareness or much effort, and are often hard to explain to someone else

79
Q

Phonological Loop

A

deals with auditory information and preserves word order; it has a limited capacity

80
Q

Phonological Store

A

holds words that are heard

81
Q

Recency Effect

A

the tendency for people to remember the last five or so words from the end of the list

82
Q

Retroactive Interference

A

occurs when a newer memory interferes with an older one

83
Q

Rough and Atkinson 1975

A

a 1975 study by Michael Rough and Richard Atkinson on mental images and memory. Participants were asked to learn sixty Spanish words but only half were taught to use the key word technique, which can be used to learn foreign language vocabulary and involves mental images. On average, the participants who learnt to use the key word technique did sixty percent better than those who didn’t

84
Q

Schema (pl. schemata)

A

a word psychologists use to describe a mental framework in which you file all knowledge about certain situations. For example, if you apply concept formation to dentist, you might categorise it as occupation, but your dentist schema would include everything you associate with the dentist. Everyone’s schemata are different.

85
Q

Semantic Memory

A

contains knowledge of the world, such as the capital of France. These are stored in concepts, are generally less personal and less vulnerable to distortion or forgetting and are not time-stamped, so we do not generally remember where we learnt them

86
Q

Serial Position Effect

A

when asking people to remember a list of words which is greater than the capacity of short term memory they have a tendency to remember words from the beginning of the list

87
Q

Skim Reading

A

psychologists have found it is easier to memorise things if you skim read before close reading something

88
Q

Stein and Memon (2006)

A

This Brazilian study found that CI increased the amount of correct information obtained and the detail of information when compared with normal interviewing techniques

89
Q

Tulving and Psota (1971)

A

participants were given 6 different word lists to remember, each consisting of 24 words divided into 6 different categories. One group was asked to simply write down as many words as they could remember and one was given category names. The second group performed significantly better than the first

90
Q

Underwood and Postman (1960)

A

involved asking people to remember lists of paired words. Participants later had their recall tested to see if they remembered the first or second list better. A control condition was used to see what recall will occur when there is no interference

91
Q

Verbal Rehearsal

A

repeating something multiple times to improve memory

92
Q

Visuo-Cache

A

stores visual and spatial information

93
Q

Visuo-Spatial Sketchpad

A

stores visual and spatial information and has a limited capacity of 3-4 items; it was subdivided by Logie

94
Q

Weston Bousfield Experiment 1953

A

Bousfield asked participants to learn a list of 60 words that could be divided into four categories. Though the words were presented in a random order, the participants tended to remember them in groups, and remember them better if they were given category headings as cues

95
Q

Working Memory Model

A

states that memory is not just one store but a number of different stores, states that we can simultaneously process different things provided different parts of the brain are used

96
Q

Wright and Holliday (2007)

A

earlier studies have shown that recall decreases significantly between the ages of 75-95, however this study showed that the CI technique leads to older participants recalling significantly greater detail without giving any false information

97
Q

Yerkes-Dodson Law (1908)

A

says that performance in memory or recall is best in conditions that arouse medium anxiety levels, such as an experiment

98
Q

Yuille and Custhall (1986)

A

a thief stole guns and money in broad daylight, shot the shop owner who then shot and killed him. The witnesses recalled all of the important information accurately in detail, even after police used leading questions to try and throw them. This shows that real life cases involving recall contradict laboratory studies
