[Review on the study of the theory of the mind in pervasive development disorders and schizophrenia].

The theory of mind (ToM) is a new concept which could be defined as the ability to make inferences on the intentions of others. This capacity has been used to explain childhood autism symptoms and recently an attempt has been made to refer it to schizophrenia. The authors aim to review the theory of mind concept, the different questions that could appear in neurocognitive sciences and the utilities that this hypothetical model has been given in the clinical practice. The authors also consider the contributions and restrictions that its use has in the field of pervasive developmental disorders and schizophrenia.
