Social mind and theory of mind
Explanation
Theory of Mind (ToM) is the capacity to attribute mental states (beliefs, desires, intentions, emotions) to oneself and to others, to understand that those states may differ from one's own and to predict behaviours from them. The term was coined by Premack and Woodruff in 1978 in a study on chimpanzees and has become a central concept of cognitive, developmental and comparative psychology.
The classic experiment is the false-belief task, devised by Wimmer and Perner (1983) and popularised by Baron-Cohen as the Sally-Anne task. The child is shown a scene where Sally puts an object in a box and leaves; in her absence, Anne moves it to another. When Sally returns, where will she look for it? Children under 4 typically answer where it really is (they do not understand false beliefs); older ones answer where Sally believes it is. This is how a metacognitive capacity that structures social life emerges.
This capacity seems partially affected in autism, which Baron-Cohen articulated in his famous mind-blindness hypothesis: systematic difficulties in attributing mental states may explain part of the social challenges of the autistic spectrum. Subsequent research has nuanced the picture (not all autistic people have the same profile; there are implicit forms of mentalisation), but the framework remains important for understanding cognitive variations.
Neuroscience has identified a mentalisation network: medial prefrontal cortex, temporoparietal junction, superior temporal sulcus, temporal pole. These regions activate when we think about mental states (our own or others'), read stories with intentional characters, predict behaviours. The network develops during infancy and consolidates in adolescence. Lesions or dysfunctions in these areas affect the ability to relate socially in the normal way.
For consciousness, theory of mind is central. Human consciousness is not only consciousness of the world, but consciousness of minds (one's own and others') immersed in shared worlds. Without this capacity, our social, linguistic and moral life would be radically different. Some theories even suggest that reflective consciousness (knowing that one knows) and theory of mind share mechanisms: we think about ourselves as if we were another whom we observe.
There are important debates about whether theory of mind is modular and uniquely human, or more continuous with primates and other animals (studies with chimpanzees, corvids, dogs have shown partial capacities for attributing mental states). It is also debated whether it is a dedicated module or a case of general mental simulation. In any case, the social mind is one of the indispensable frameworks for understanding why human consciousness is so deeply intersubjective and cultural.
Strengths
- Productive and replicable empirical programme.
- Explains specific deficits in autism and other clinical pictures.
- Integrates evolution, development and neuroscience.
- Highlights the social-recursive nature of consciousness.
Main critiques
- Enactive critique: social understanding does not require a representational theory.
- The theory-of-mind hypothesis in autism contested (huge variability).
- Possible non-representational forms of mentalisation (simulation, narrative).
