40
What is 'memory conformity' in post-event discussions?
Memory conformity occurs when people align their memories with others due to believing the other person's account is more accurate.
41
What did Anastasi and Rhodes argue about own-age bias in eyewitness testimony?
They argued that participants recall faces from their own age group with higher accuracy
42
What are demand characteristics
and how might they affect EWT research?
43
What did Johnson and Scott (1976) show about the weapon focus effect?
They found that participants in a high-anxiety condition (seeing a bloody knife) had 16% lower recall accuracy compared to a low-anxiety condition (seeing a pen).
44
What did Yuille and Cutshall (1986) find about the positive effects of anxiety on eyewitness recall?
They found that witnesses to a real-life shooting with high anxiety had 11% higher recall accuracy after 5 months than those with low anxiety.
45
What ethical issues arise in anxiety and EWT research?
Exposing participants to distressing events
46
What does the Yerkes-Dodson Law suggest about anxiety and eyewitness accuracy?
It suggests an inverted-U relationship
47
What is Pickel's criticism of the weapon focus effect?
Pickel suggested that the weapon focus effect could be due to surprise rather than anxiety
48
What did Fisher et al. (1987) contribute to the cognitive interview?
They developed the enhanced cognitive interview
49
What did Kohnken et al. (1999) find about the cognitive interview's accuracy?
They found that while the cognitive interview increased correct recall by 81%
50
What did Milne and Bull (2002) find about the stages of the cognitive interview?
They found that 'context reinstatement' and 'report everything' produced the greatest recall accuracy
51
What did Miller suggest about the chunking method in STM?
Miller suggested that chunking helps us recall information by grouping items into 7 +/- 2 units.
52
What is a limitation of Miller's STM capacity research?
More recent research suggests that STM capacity may be closer to 4 chunks
53
What is a criticism of Jacobs' research on STM capacity?
Jacobs' study lacked standardisation and scientific control
54
What is a criticism of Peterson et al.'s study on STM duration?
The study used artificial stimuli (consonant syllables) with low ecological validity
55
What are the two types of rehearsal in memory processing?
Maintenance rehearsal (repetition) and elaborative rehearsal (linking new information to existing knowledge).
56
What are the key stores in the sensory register of the multi-store model (MSM)?
The sensory register contains a sub-store for each of the five senses
57
What determines whether information passes from the sensory register to STM?
Attention is required for information to move from the sensory register to short-term memory.
58
What is a weakness of the multi-store model (MSM) regarding LTM?
The MSM oversimplifies LTM by treating it as a single store
59
What does procedural memory store?
Procedural memory stores our knowledge of learned skills
60
How does retrieval occur in the multi-store model of memory (MSM)?
Retrieval occurs when information is transferred from long-term memory back into short-term memory.
61
What did Craik and Watkins (1973) argue about rehearsal in the MSM?
They argued that elaborative rehearsal is more important than prolonged rehearsal for transferring information to LTM.
62
What type of memory recall did Cohen and Squire distinguish?
They distinguished between declarative (episodic and semantic) and non-declarative (procedural) memory.
63
What do the cases of HM and Clive Wearing suggest about LTM?
They suggest that different types of LTM (procedural
64
What is the phonological loop in the working memory model (WMM)?
The phonological loop processes auditory information and allows for maintenance rehearsal of sounds.
65
What are the two components of the phonological loop in the WMM?
The phonological store (stores auditory information) and the articulatory process (allows for repetition of sounds).
66
What does the visuo-spatial sketchpad do in the working memory model?
It processes visual and spatial information
67
What is the role of the central executive in the WMM?
The central executive allocates tasks to the other slave systems and has a limited processing capacity.
68
What did Baddeley suggest about the capacity of the visuo-spatial sketchpad?
Baddeley suggested that the visuo-spatial sketchpad has a capacity of around 4-5 chunks.
69
What is a key strength of the working memory model (WMM)?

70
What is a key limitation of the central executive in the WMM?
The central executive is not well-defined
71
What did Tulving's encoding specificity principle (ESP) suggest?

What are the two types of cues involved in retrieval failure?
Context-dependent cues (external) and state-dependent cues (internal).
73
What did Baddeley argue about the real-life relevance of context effects in retrieval failure?

74
What is memory substitution according to Loftus and Palmer's (1974) study?
Memory substitution occurs when misleading information changes a witness's memory of an event.
75
What is the response-bias explanation in Loftus and Palmer's study?
The response-bias explanation suggests that leading questions influence the eyewitness's answer without altering their memory.
76
What did Pickel (1998) demonstrate about unusual stimuli and memory?
Pickel found that the weapon focus effect might be due to the unusualness of an object (e.g.
77
What is the 'fight or flight' response's role in EWT accuracy?
The 'fight or flight' response increases attention to external cues
78
What is one ethical issue in Johnson and Scott's anxiety and EWT research?
Participants were exposed to distressing situations
79
What is the 'Please-U' effect in eyewitness testimony studies?
The 'Please-U' effect occurs when participants give responses they believe the researcher wants to hear

How does the cognitive interview reduce the effects of misleading information?
By encouraging witnesses to report everything
81
What is the key aim of the enhanced cognitive interview?
The aim is to improve communication between the interviewer and the eyewitness by focusing on social dynamics and building rapport.
82
Why do some police forces struggle with using the cognitive interview?
