Two Main Dimensions Of Theory Of Mind (ToM).

The social-perceptual component of ToM involves the ability to determine the mental states of others using immediately available non-verbal cues (e.g., eyes, face, hand gestures). This maps on to the cognitive empathy component, and is what is measured by the Reading the Mind in the Eyes test. This component of theory of mind shows up earlier in development and is related to the right hemisphere medial temporal and orbitofrontal regions of the brain.

In contrast, the social-cognitive component of ToM (not to be confused with cognitive empathy) involves the ability to reason about the mental state of others, and use that reasoning to predict or explain their behavior. This ability involves inferring what others know or believe to be true apart from what you know or believe to be true. This is a later developing skill and is more strongly dependent on linguistic capacities. This component of theory of mind draws on left hemisphere circuitry involving medial frontal areas and the temporoparietal junction.

Daniel Nettle and Bethany Liddle found a relationship between the social-cognitive component of theory of mind, but not the social-perceptual component. It appears that the agreeable, compassionate, altruistic aspect of our human nature is only associated with the higher-level, social-cognitive component of theory of mind.
