title: Impaired theory of mind performance in patients with recurrent bipolar disorder: Moderating effect of cognitive load.
abstract: The aim of this study was to investigate theory of mind (ToM) performance on tasks that varied in the demands they placed on cognitive processing resources in a sample of 14 bipolar patients with subsyndromal illness and 14 controls. Patients showed impaired performance on cognitively demanding second-order ToM tasks. Reduced ToM performance was associated with longer illness duration, and with increased symptom severity.
