Forensic and Legal Psychology
Psychology and the Law
Memory and Testimony
Forensic psychology applies clinical skills to legal arenas, while legal psychology focuses on cognitive and social principles within the justice system. A major area of study is eyewitness testimony. Memory is reconstructive, not a perfect recording. Elizabeth Loftus's research demonstrated the misinformation effect, showing how post-event information can distort memory.
Key Concepts in Forensic Assessment
The Misinformation Effect
Leading questions can alter a witness's memory of an event. For example, asking 'How fast were the cars going when they smashed into each other?' yields higher speed estimates than using the word 'hit'.
