Post event discussion

• when witnesses have the opportunity to discuss the event with others who can influence their memory of the details
• Gabbert et al- pps watched a video of a crime from one of two different angles, half the pps could discuss what they saw with someone who witnessed a different angle to them and the other half could not, pps who discussed the crime reported things in their testimony that they could not have witnessed from their original angle.
• Gabbert et al evaluation- standardised- control over extraneous variables, can be sure they are only measuring the variable of post-event discussion and not any other on eyewitness testimony
• criticisms of et al's research- lacks mundane realism, only a video and is an experiment which is not from real life, where people may have to go to prison based on what the pp has said, the results may therefore lack ecological validity,
• real world application to et al's research- led to the police putting focus on interviewing the eyewitness as soon as possible after the event in order to eliminate the variable of post event dicussion,
