Are False Memory and Creative Thinking Mediated by Common Neural Substrates? An fMRI Meta-Analysis

Area of Science:

• Cognitive Neuroscience
• Psychology

Background:

• Episodic retrieval supports divergent creative thinking by enabling information recombination.
• Constructive memory processes, while beneficial for creativity, can also lead to memory errors, such as false recognition.

Purpose of the Study:

• To investigate the neural substrates underlying the link between false recognition and divergent creative thinking.
• To determine if shared neural regions support both false recognition and divergent thinking using meta-analysis of fMRI studies.

Main Methods:

• Conducted a meta-analysis of functional magnetic resonance imaging (fMRI) studies.
• Analyzed neural activity associated with false recognition (DRM paradigm) and divergent creative thinking (AUT).
• Tested for statistical overlap in brain regions identified by individual meta-analyses.

Main Results:

• Individual meta-analyses successfully replicated prior findings for both false recognition and divergent thinking neural activity.
• No significant statistical overlap was found between neural regions associated with false recognition and divergent creative thinking.
• This null finding suggests distinct neural mechanisms may underlie these two cognitive functions.

Conclusions:

• While behavioral studies show a correlation between false recognition and divergent thinking, their neural underpinnings may be distinct.
• The findings suggest that different generative retrieval processes might be engaged during divergent thinking compared to false recognition.
• Further research is needed to fully elucidate the complex relationship between memory processes and creative cognition.
