1. The document reports on two experiments that examined how factors like post-event information, presentation mode, emotionality, and gender affect eyewitness accuracy and memory. 2. In experiment 1, subjects were exposed to staged or video events and given consistent, misleading, or no post-event information. Memory was highest in the consistent condition and lowest in the misleading condition. 3. Experiment 2 examined how emotionality and gender influence memory, finding that unpleasant events and females were more susceptible to post-event information.
