Memory Distortions: Impact on Identification and Conviction

  • In an experiment, participants were shown pairs of faces, with one being altered, and asked to identify the original face silently.
  • Participants were able to accurately identify the original face without any quiz for the second pair of faces.
  • For the third pair, an altered face was substituted, leading most participants to incorrectly choose the altered face.
  • Post-event activities, like being seduced into picking an altered face, influenced participants to stick with the wrong choice even when the true face was presented.
  • Post-event activities inducing people to pick the wrong face affected their later ability to choose the correct face.
  • A wrongful conviction case involving Ronald Cotton, accused of raping Jennifer Thompson, highlighted the impact of cross-racial identification and memory distortions.
  • Jennifer Thompson's misidentification of Ronald Cotton led to his wrongful conviction, later overturned by DNA testing.
  • Jennifer's meeting with Ronald, seeking forgiveness, led to their friendship, advocacy work, and co-authoring a book titled "Picking Cotton."
  • Studies on memory distortions, like the misinformation effect, showed how post-event suggestions could lead to false identifications and memories.
  • Research on rich false memories involved planting suggestions about past experiences, leading to the creation of vivid false memories, even in extreme cases.
