Document Summary
Chapter 5 eyewitnesses to crimes and accidents. Why do misidentifications and subsequent convictions occur: after an initial eyewitness account the police stop looking, sitting in the defendant chair = suspect/perp, witnesses are scared and identify the wrong person or they lie. Police questioning: open ended versus closed, what color was the car, was the car red or blue, leading questions/statements, okay, so it was 4:30 in the morning, you must have been tired. Basic information processing: perception & memory: encoding: the process of entering a perception into memory, how we learn acquire information. Commission of the offence: environmental situation, witness characteristics, other-race effect, weapon focus. Encoding is effected by many things: length of presentation of stimuli, complexity of the event, witness characteristics. Inaccurate or incomplete encoding: the phase of memory process referring to the retention of information, how much information do we keep, research, we lose information rapidly.
