Overview
This lecture explores the case of Steve Titus, who was wrongfully convicted due to faulty eyewitness memory, and discusses the psychological science of false memories, their causes, effects, and ethical considerations.
The Case of Steve Titus
- Steve Titus was wrongfully convicted of rape due to mistaken eyewitness identification.
- The victim initially said Titus was "the closest" in a photo lineup, later became "absolutely positive" in court.
- The real perpetrator was later found and confessed, exonerating Titus.
- Titus lost his job, fiancée, and savings, and died of a stress-induced heart attack before his civil trial.
Memory and Eyewitness Testimony
- Many believe memory acts like a recording device, but psychological research shows it is reconstructive and malleable.
- 300 innocent people in the U.S. were exonerated by DNA after wrongful convictions, about three-fourths due to faulty memory.
- Leading questions and misinformation can distort eyewitness memory, such as misremembering details or identifying the wrong person.
Research on False Memories
- Studies show suggestive questioning can implant false memories, even in stressful situations (e.g., military interrogation).
- Misinformation can come from leading questions, conversations with others, or media coverage.
- Psychotherapy techniques (imagination, hypnosis, exposure to false info) can lead to the creation of rich, false memories of traumatic events.
Planting False Memories: Experiments
- Experiments successfully planted false childhood memories (e.g., getting lost, nearly drowning, witnessing demonic possession) in subjects.
- Such false memories can change later behavior, including food preferences.
Ethical and Social Implications
- Planting false memories raises ethical questions, especially in therapeutic or parental contexts.
- Public reaction against discussing these issues included hostility and lawsuits against the lecturer.
- False memory research shows we cannot reliably distinguish false memories from true ones without independent evidence.
Key Terms & Definitions
- False Memory — A recollection of an event that did not occur, or is substantially different from what actually happened.
- Eyewitness Memory — Recollection of events by someone who witnessed them, often used in legal settings.
- Misinformation Effect — The alteration of memory by exposure to misleading information after an event.
- Constructive Memory — The concept that memory is actively constructed and can be modified by suggestive influence.
Action Items / Next Steps
- Reflect on the fallibility of memory and the need for corroborating evidence in critical situations.
- Consider reading more about the misinformation effect and reconstructed memory in psychology textbooks.
- Be cautious of suggestive questioning and media information influencing your own or others' memories.
