Describe how post-event discussion can affect eyewitness testimony.
occurs when there is more than one witness to an event
witnesses discuss what they have seen (with co-witnesses or other people)
memory conformity, false memory, reconstruction, confabulation can occur
information is added to a memory after the event has occurred information that is added may be misleading
the accuracy of the witness’s recall may be reduced
false memories can be stimulated by misleading post-event discussion
use of evidence to illustrate, eg Gabbert et al. (2003) • effects of post-event discussion can be reduced if participants are warned of the effects (eg Bodner et al. 2009).
