When knowing becomes remembering: individual differences in susceptibility to suggestion.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Memory Studies

Background:

• Source-monitoring errors occur when individuals misattribute the origin of memories.
• Autobiographical memory retrieval is susceptible to distortions and confabulation.
• Understanding factors influencing memory accuracy is crucial for various applications, including psychotherapy.

Purpose of the Study:

• To investigate factors influencing source-monitoring errors in autobiographical memory.
• To examine the effect of guided visualization on the 'know-to-remember' phenomenon.
• To identify individual difference variables associated with shifts in memory certainty.

Main Methods:

• Experiment 1: Undergraduates recalled childhood memories (known but not remembered, remembered, or source-uncertain). Experimental groups received guided visualization; control groups performed a visual search task.
• Experiment 2: Assessed individual difference variables (e.g., extraversion, locus of control) in relation to the 'know-to-remember' shift.
• Utilized guided visualization and detailed questioning to enhance memory focus.

Main Results:

• Guided visualization significantly increased the perceived rememberedness of 'known' memories.
• Individual difference variables such as extraversion, external locus of control, memory fear content, and overall affect predicted the 'know-to-remember' shift.
• Specific memory characteristics (fear, affect) influenced the degree of certainty shift.

Conclusions:

• Guided visualization can alter the subjective experience of memory, potentially blurring the lines between knowing and remembering.
• Personality traits and memory content play a significant role in the malleability of autobiographical memory certainty.
• Findings have implications for understanding memory distortions in therapeutic contexts and for memory recovery techniques.
