Are high hypnotizables especially vulnerable to false memory effects? A sociocognitive perspective

Area of Science:

• Psychology
• Cognitive Science
• Forensic Psychology

Background:

• Legal cases involving hypnosis raise concerns about the reliability of testimony.
• The defense in a UK case questioned plaintiff testimony due to high hypnotizability and potential false memories.
• Existing evidence on hypnotizability and false memory production is often inconsistent.

Purpose of the Study:

• To examine the relationship between hypnotizability and the production of false memories.
• To investigate whether a sociocognitive perspective can clarify inconsistent findings.
• To test the hypothesis that instructions emphasizing accuracy during hypnosis may alter false memory susceptibility.

Main Methods:

• Review of legal cases and existing literature on hypnosis and memory.
• Presentation of two preliminary studies involving participants with varying hypnotizability levels.
• Experimental manipulation of instructions during hypnosis, focusing on accuracy versus productivity.

Main Results:

• Preliminary studies suggest higher hypnotizability may correlate with resistance to false memories when accuracy is stressed.
• Misleading information presented during hypnosis did not disproportionately create false memories in highly hypnotizable individuals under accuracy-focused conditions.
• The sociocognitive perspective offers a framework for understanding these nuanced findings.

Conclusions:

• High hypnotizability is not inherently linked to a greater propensity for producing false memories.
• Instructions emphasizing accurate reporting during hypnosis may mitigate the risk of false memory formation in highly hypnotizable individuals.
• The findings challenge the assumption that hypnotizability is a direct predictor of memory unreliability in legal contexts.
