Is the content of confabulation positive? An experimental study

Area of Science:

• Neuroscience
• Psychology
• Cognitive Science

Background:

• Clinical observations suggest confabulation, or false memory creation, may exhibit self-serving and positive emotional biases.
• Limited experimental research exists on the emotional valence of confabulated memories.

Purpose of the Study:

• To experimentally investigate the emotional content of confabulation.
• To compare the emotional valence of false memories in amnesic patients who confabulate versus control groups.

Main Methods:

• Elicited false memories from 10 amnesic confabulating patients, 10 healthy controls, and 4 amnesic non-confabulating patients.
• Naïve raters assessed the emotional valence of confabulated memories from interview transcripts.

Main Results:

• Confabulating patients' false memories were significantly more pleasant and self-enhancing than controls'.
• A paradoxical finding emerged: greater patient depression correlated with more positive confabulation content.
• The study indicates confabulated content is predominantly positive.

Conclusions:

• Confabulation content is generally positive, suggesting a role for emotion and motivation in its formation.
• Findings have implications for understanding the mechanisms of confabulation and its clinical management.
