Stages: perception/attention, encoding, short- term, long- term and retrieval stage. Both can be manipulated in lab settings. Dependent variables: recall of the event/crime, recall of culprit, and recognition of the culprit. Recall takes the form of open- ended recall (free narrative), also direct question recall (specific questions). Recall examined for the amount of info reported, the type and accuracy of the info. Recognition task is usually lineup, voice/clothing lineup common too. Examine for the accuracy of decision, types of errors make. Recall memory is critical. Interviewing eyewitnesses: variations in pos. Leading questions the misinformation effect. 2 experiments demonstrating the effect.
