ERP and Behavioral Correlates of Temporal Processing Dysfunction in Schizotypy

Abstract
Symptoms of schizophrenia have been attributed to deficits of temporal processing. Research suggests that patients with schizophrenia have an accelerated internal clock. The current research employs a finger-tapping task to assess timing abilities in schizotypy -- a constellation of personality traits with features similar to schizophrenia --and utilizes electrophysiological methodologies to explore the neural activity associated with temporal processing. Analyses revealed that both response variability in the finger tapping procedure and the amplitude of the N100 omission-evoked potential are associated with schizotypal personality measures. The results are consistent with previous research and further indicate that the amplitude of the omission-evoked potential may be an indicator of formation of temporal interval representations.
