How does high schizotypy affect empathy and social thinking?

What is Theory of Mind (ToM) as defined in the context of schizophrenia research?

Theory of Mind (ToM) is defined as the inability or ability to attribute intentions and mental states to others, and is assumed to be an integral characteristic of schizophrenia.

How do cognitive and affective ToM errors typically differ in patients with schizophrenia?

Schizophrenia patients commit more mistakes when attributing emotional states to others (affective ToM) compared to when they attribute thoughts or intentions (cognitive ToM).
