Abstract
A number of cognitive and behavioral variables influence the performance in tasks of theory
of mind (ToM). Since two of the most important variables, memory and explicit expression,
are impaired in schizophrenic patients, the ToM appears inconsistent in these
patients. An ideal instrument of ToM should therefore account for deficient memory and
impaired ability of these patients to explicitly express intentions. If such an instrument
is developed, it should provide information that can be used not only to understand the
pathophysiology but also to monitor patients.
