Quick Summary

Eyewitness memory is not a perfect recording of events but rather a reconstruction that can be influenced by various factors. Research shows that the accuracy of eyewitness testimony can be degraded by exposure to news accounts or photographs of a suspect, leading to a blending of memories and the creation of inaccurate recollections. The way questions are phrased can also alter memory.1

False memories can be implanted, even in laboratory settings, where participants may recall words that were not presented if they are related to a theme. This highlights how imagination can significantly impact memory. Therefore, eyewitness accounts should be approached with caution due to the reconstructive nature of memory and the potential for distortion.1
