Memory Study Guide

The study by Braun, Ellis and Loftus (2002) investigated how misleading information in advertising can implant false memories in people. The researchers conducted an experiment where participants viewed an advertisement for Disneyland that suggested they had met Bugs Bunny or Ariel, even though these characters are not traditionally associated with Disneyland (Bugs Bunny is a Warner Bros. character). The participants were divided into groups, with some exposed to the misleading ad and others to a control ad. After viewing the ads, participants completed a questionnaire designed to assess their memories of a childhood trip to Disneyland. The key finding was that participants exposed to the misleading advertisement were more likely to report having shaken hands with Bugs Bunny or met Ariel during their childhood trip to Disneyland, compared to the control group. This study provides strong evidence for the concept of false memory implantation and how post-event information, such as advertising, can distort or create memories of past experiences. It highlights the reconstructive nature of memory, where personal recollections are not always exact recordings of events but can be influenced by external suggestions and information encountered after the original event. The ethical implications of such research, particularly in real-world contexts like eyewitness testimony or therapy, are significant, as is the practical implication for advertising standards.

The case study of Clive Wearing, documented by Wilson, Kopelman, and Kapur in 2008, is a critical piece of evidence regarding the nature of human memory, particularly the distinction between different types of long-term memory. Clive Wearing was a renowned musician who, in 1985, contracted herpes simplex encephalitis, a virus that severely damaged parts of his brain, including the hippocampus and frontal lobes. This damage resulted in profound and debilitating memory deficits. He developed both anterograde amnesia (inability to form new memories) and severe retrograde amnesia (loss of many pre-existing memories). However, uniquely, his procedural memory and some aspects of his semantic memory, such as knowing he had children and the meaning of certain words, remained relatively intact. He could still fluently play the piano and conduct a choir, skills he had mastered before his illness. This case vividly illustrates that memory is not a single, unified system but is composed of separate, distinct components. His diary entries, which became repetitive and often showed confusion, further highlighted his inability to retain new information for more than a few seconds. This study is crucial for understanding the biological basis of memory and supports theories distinguishing between episodic, semantic, and procedural memory.
