Self-reference recollection effect and its relation to theory of mind: An investigation in healthy controls and schizophrenia.

This study explores the links between the Self-Reference Effect (SRE) and Theory of Mind (ToM) in typical adults and patients with schizophrenia. Participants were assessed with a self-referential memory paradigm investigating the mnemonic effect of both semantic and episodic self-reference with a recognition task associated with the Remember/Know/Guess paradigm. They also completed a self-descriptive scale and shortened versions of the attribution of intention task and the reading the mind in the eyes test as measures of cognitive and affective ToM respectively. Unlike typical adults, the patients showed no semantic SRRE (correct recognition associated with remembering), and there was no episodic SRRE and no SRE (on the number of correct recognitions) in either group. Semantic SRRE was correlated with the affective ToM in patients and with the positivity of the self-concept in the healthy group. We discuss that patients and typical adults use different strategies during self and other-reflection.
