What has research suggested about post event discussion

Suggests that discussing events an contaminate a witness memory

(Memory contamination)

2nd impact on memory

• memory conformity

• Costlinesses go along with what each other have said

What tends to happen when there is POD

Tend to form a census view of what happened ‘police won’t be getting accurate info

What do police do now

Try and separate witnesses from each other as quickly as possible to help prevent POD and damaging info

What’s the main study from Gabbert

Pppt in pairs = watch different video of same event

Video filmed from different perspectives - each person had distinct set of details from video

Condition 1 - encouraged to discuss event before each partner recalled what they watched

Control condition - no POD

What was the results of Gabbert

71% who had POD - mistakenly recalled items (came from POD)

0% of control group included items fmo other videos

Result from memory contamination - meomeory changed by discussion or memory conformity where there’s been no change in memory but witness feels pressure to conform
