⚪️ Memory - Post-Event Discussion Flashcards
What is post event discussion and what can it lead to
Occurs when witnesses discuss an event after it has happened. It can lead to memory contamination as witness may incorporate information from others into their own memoriesn
According to the Source Monitoring theory, how does post event discussion affect EWT
According to the source monitoring theory, memories of the event are genuinely distorted. They can recall the event but they can’t recall where it came from (source confusion)
What does the conformity theory argue about post event discussion
Argues that EW memories are not actually distorted by post event discussion. Instead, the eyewitness’s recall appears to change only because they go along with the accounts of co-witnesses
Method of Gabbert et al (2003)
- participants watched videos of the sesame event from different angles
- each angle showed unique detail
- witness a - stealing money
- witness b - cannot see stealing money
- group 1 allowed to talk
- group 2 no discussion
Results of gabberts study
- 71% of participants in co-witness condition reported information from other witnesses
- 60% reported a crime they hadn’t actually seen
- demonstrates how post event discussion can alter memory
Strengths of research
- conducted in controlled lab experiment
- allows for careful control of variables
- cause and effect relationships
- can be replicated to check reliability
Limitations of research
- artificial nature of the studies
- video rather than witnessing real events
- meaning lack of emotional involvement ir anxiety present in real life situations
Implications of post event discussion
Awareness of post event discussion effects is crucial. Now use careful questioning techniques
