What does the tunnel theory of memory argue

A

people have enhanced memory for central events

therefore weapon focus due to anxiety can have this effect

Q

flight or flight increases alterness so this improves

20
Q

flight or flight increases altertness so it improves memory , but how

A

we become more aware of cues in the situation

21
Q

who conducted a study of an actual shooting in a gun shop

A

Yuille and Cutshall

22
Q

What did the shop owner do in Y and C study

A

shoot the thief dead

23
Q

How many witnesses in YC take part

A

13/21 witnesses

24
Q

when were the 13/21 witnesses that took part interviewed

A

4-5 months after the incident

25
in the Y&C study the 13 witnesses were interviewewd what were these compared to
original police interviews at the time shooting
26
How was accuarcy determined in the Y&C study
number of details reported in each account
27
In the Y&C study as well as being interviewed/in the interview what two things were witnesess asked to do
rate how stresed they felt ona 7 point scale whether they had emotional problems since incident e.g sleeplessness
28
What were the findings for the Y&C study
witnesses very accurate in their accounts little change in amount recalled/accuracy in 5 months
29
Y&C study - although there was little change in amount recalled/accuracy ....
some details were less accurate e.g colour of items age/height/weight estimates
30
in the Y&C study which group was most accurate
particpant who reported the highest levels of stress
31
what was the accuracy for teh Y&C study of the high stress group compared to less stress
88% compared to | 75% with the less stressed group
32
Overall what does the Y&C study suggest
anxiety doesn't have a detrimental effect on the accuracy of EWT in real world context but rather may enhance it
33
What did Yerkes and Dodson say about the inverted U shape
relationship between emotional arousal and perfomance looks like an inverted U
34
What did Deffenbacher review
21 studies of EWT
35
What did Deffenbacher note after reviewing 21 studies of EWT
he noted contradictory findings of effects of anxiety
36
What did Deffenbaxher use to explain the contradictorary findings
Yerkes Dodson Law
37
What is the Yerkes Dodson Law
inverted U theory states performance increases with stress but only to a certain point where it decreases drastically
38
1. Yerkes Dodson Law in depth. When we experience a crime/accident we become
emotionally and physiologically aroused
39
2.Yerkes Dodson Law in depth. What do we experience referring to emotionally and phsyiologically aroused
anxiety (emotional) | as well as phsyiological changes (flight or flight response)
40
3Yerkes Dodson Law in depth. Lower levels of anxiety/arousal produce
lower levels of recall accuracy
41
4Yerkes Dodson Law in depth. Memory becomes more accurate as
the level of anxiety/arousal increases
42
However there is an optimal level of anxiety which is
point of maximum accuracy if EW experiences anymore arousal their recall suffers drastic decline
43
evaluation for FATAOEWT anxiety
limitation - johsnon and scott study may not have tested anxiety strenght - evidence supports view anxiety has negative effects on accuarcy of recall strength - evidence shows anixty can have positive effects on acccuracy of recall - christianson hubinette cp - C and H interviewed pt several months after the event
44
Explain limitayion why study by Johson and Scott may not have tested anxiety study by Johson and Scott may not have x anxiety reason pt focused on weapon cause they was x @ what they saw rather than x x conducted experiemtn usinf x x , x and x or a x chicken as hand held items in a x salon video scissors were high x low x EW accuracy x in xand x (high x conditions) this suggests weapon focus effect due to x rather than x/x therefore tells us nothing x about the effects of x on EWT
study by Johson and Scott may not have tested anxiety reason pt focused on weapon cause they was suprised @ what they saw rather than scared Pickel conducted experiemtn usinf hand gun , scissors and wallet or a raw chicken as hand held items in a hairdressing salon video scissors were high anxiety low usualness EW accuracy poorer in chicken and handgun (high unsusualness conditions) this suggests weapon focus effect due to unusualness rather than anxiety/threat therefore tells us nothing specifically about the effects of anixety on EWT
45
explain strength 1 - evidence supporting view anxiety has a negative effect on recall x supporting view that x has a x effect of recall x and Mesout used x measure of xx to divide the pt into x and low anxiety groups anxiety clearly x pt ability to recall details about x in London Dungeon's x therefore suggests high level of anxiety does have a x effect on immediate xx recall of a x event
evidence supporting view that anxiety has a negative effect of recall Valentine and Mesout used obj measure of HR to divide the pt into high and low anxiety groups anxiety clearly disrupted pt ability to recall details about actor in London Dungeo Labry therefore suggests high level of anxiety does have a negative effect on immediate EW recall of a stressful event
46
Explain - anxiety can have +ve effects on EW recall accuracy x and x interviewed x wintesses to bank x those involved x/directly - x and xworkers recall x%+ accurate across all x w direct x being most acucrate findings x as confirm anxiety does not x accuracy of recall for EW and may even x it
hubinette and christianson interviewed 58 wintesses to bank robbery those involved in/directly - bystanders and bankworkers recall 75%+ accurate across all witnesses w direct w being most acucrate findings miportant as confirm anxiety does not reduce accuracy of recall for EW and may even enhance it
47
Explain CP to anxiety can have +ve effects on EW recall accuracy researchers interviewed pt x months after event therefore had no x over what happened to their pt in the x time e.g xxx effects of anxiety may have been x by theses other factors and its x to assess by the time pt were interviewed therefore possible that the lack of x over x variables may be x for these findings, x their support
researchers interviewed pt several months after event therefore had no control over what happened to their pt in the intervening time e.g PED effects of anxiety may have been overwhelmed by theses other factors and impossible to assess by the time pt were interviewed therefore possible that the lack of control over confounding variables may be responsible for these findings, invalidating their support
