Seeing minds - a signal detection study of agency attribution along the autism-psychosis continuum.

Introduction: Diametrically aberrant mentalising biases, namely hypermentalising in psychosis and hypomentalising in autism, are postulated by some theoretical models. To test this hypothesis, we measured psychotic-like experiences, autistic traits and mentalising biases in a visual chasing paradigm.

Methods: Participants from the general population (= 300) and psychotic patients (=26) judged the absence or presence of a chase during five-second long displays of seemingly randomly moving dots.
