ABSTRACT

This study investigated the relationships between auditory time perception and neuropsychological functions in patients with schizophrenia using Synchrony/Asynchrony discrimination (SA) task, Temporal Order Judgment (TOJ) task and comprehensive neuropsychological tests. Participants were asked to respond whether two tones were presented simultaneously or not in SA task, whereas in TOJ task, participants were asked to judge which tone was presented prior to the other tone. Thirty patients with schizophrenia and 31 normal controls participated in this study. The schizophrenia group showed significantly lower accuracy rates than did the control group in both SA and TOJ tasks. Performance on the SA task was positively correlated with attention., whereas performance on the TOJ task was positively correlated with attention, memory, executive function. Moreover, performances on the SA task were negatively associated with P3 (hallucination) symptom, and performances on the TOJ task were negatively associated with positive symptoms, P3, general psychopathology, and total score of the PANSS for schizophrenia. These findings suggest that patients with schizophrenia have deficits both in discriminating between synchrony and asynchrony, and judging temporal order. In addition, deficits of auditory time perception in patients with schizophrenia were significantly associated with schizophrenic symptoms and cognitive dysfucntions such as attention and executive dysfunctions.
