Intuitive physics ability in systemizers relies on differential use of the internalizing system and long-term spatial...

Area of Science:

• Neuroscience
• Cognitive Psychology
• Individual Differences

Background:

• Empathizing-Systemizing (E-S) theory posits two general population continuums: systemizing (understanding physical world) and empathizing (understanding social world).
• Systemizing traits have implications for vocational interests and skills in physical and social domains.
• The neural mechanisms underlying intuitive physics performance in systemizers remain largely unexplored.

Purpose of the Study:

• To investigate the intuitive physics skills of systemizers (high systemizing, low empathizing).
• To identify the distinct brain mechanisms associated with intuitive physics tasks in systemizers using functional magnetic resonance imaging (fMRI).

Main Methods:

• fMRI scans were conducted on healthy adult systemizers (N=36) while they performed intuitive physics tasks.
• Brain activation patterns were analyzed in relation to systemizing and empathizing scores and task performance.

Main Results:

• Systemizers demonstrated superior intuitive physics skills.
• Higher systemizing and lower empathizing correlated with increased activation in the default mode network (DMN), middle occipital gyrus, and parahippocampal region.
• Posterior cingulate gyrus and parahippocampal gyrus activations were uniquely linked to the systemizer brain type, independent of task performance.

Conclusions:

• Systemizers exhibit enhanced intuitive physics abilities.
• The DMN-parahippocampal complex, crucial for spatial memory, appears to be a distinguishing neural factor for systemizers in intuitive physics tasks.
• These findings highlight the neural underpinnings of systemizing cognition in understanding the physical world.
