Theory of mind and the self

Area of Science:

• Cognitive Neuroscience
• Developmental Psychology
• Neuroscience

Background:

• Self-reflection, the ability to introspect on internal states, is a key aspect of self-awareness.
• Theory of Mind (ToM) refers to the cognitive capacity to attribute mental states—beliefs, desires, intentions—to oneself and others.
• Disruptions in ToM are evident in developmental disorders like autism.

Purpose of the Study:

• To investigate whether the cognitive and neural resources for self-reflection overlap with those for Theory of Mind (ToM).
• To explore the relationship between understanding one's own mental states and understanding the mental states of others.
• To examine evidence from normal ToM development and autism research.

Main Methods:

• Review of literature on the normal development of ToM.
• Analysis of research on autism, a disorder impacting the ability to "think about thoughts."
• Discussion of functional neuroimaging studies of ToM and self-reflection.

Main Results:

• Evidence suggests that self-reflection is not a unique or privileged cognitive process.
• The cognitive and neural mechanisms underlying self-reflection appear to be shared with those used for attributing mental states to others.
• This shared basis may have evolutionary implications, suggesting self-reflection evolved from ToM functions.

Conclusions:

• Reflecting on one's own thoughts relies on the same cognitive and neural functions used for understanding others' thoughts.
• The capacity for self-reflection may have evolved from the mechanisms supporting Theory of Mind.
• This perspective challenges the notion of self-reflection as an isolated cognitive faculty.
