Positive symptoms and time perception in schizophrenia: A meta-analysis

Abstract: Positive symptoms of schizophrenia may be related to distortions in time perception. To examine this issue, we conducted a meta-analysis to determine whether positive symptoms are associated with deficits in time processing performance. MEDLINE and Web of Science were searched from January 1980 through March 2017, and all related articles and their references were scrutinized to find relevant studies. Studies were selected if they included participants with a diagnosis of schizophrenia, and reported data from … Show more

“…Timing dysfunctions can span from millisecond to second durations ( Carroll et al, 2009 ). A similar result is reported in a subsequent meta-analysis ( Ueda et al, 2018 ) in which a relation between positive symptoms of schizophrenia and temporal overestimation of supra-second durations was described ( Ueda et al, 2018 ). Finally, alterations in time processing have been documented also via qualitative approaches such as by using inductive summarizing content analysis ( Vogel D. H. V. et al, 2019 ), suggesting a link between disturbances in the experience of time and alterations in the constitution of the stream of consciousness ( Vogel D. H. V. et al, 2019 ).…”

“…Overall, the literature suggests alterations of timing, and dysfunctions at the level of insula, and one study directly relates these two observations. Because positive symptoms positively correlate with interoceptive accuracy ( Ardizzi et al, 2016 ) and time overestimation performance ( Ueda et al, 2018 ) in schizophrenia, we speculate that their interoceptive dysfunction might potentially play a direct role in their timing response (i.e., temporal overestimation). Talking about the potential link between insular activation and the perceived duration, the study by Davalos et al (2011) does not provide insight in this regard, as the data analysis provided in this study focused on the percentage of errors, with no information on the direction of errors (i.e., overestimation or underestimation error).…”

“…The importance of timing and temporal processing in movement disorders is well established (2). Alterations in aspects of temporal processing and timing have also been identified in many other neuropsychiatric conditions (1,(20)(21)(22)(23)(24). The therapeutic value of temporally based interventions (e.g., rhythmic cueing, slow rhythmic drumming) has been demonstrated for multiple neuropsychiatric conditions (25)(26)(27)(28).…”

“…Dysfunction of the SMA-basal ganglia network (Hanakawa et al 2017) may account for abnormality in temporal information processing in Parkinson's disease (Ivry 1996). Evidence indicates that patients with schizophrenia may have impaired temporal updating systems, having difficulty in interval discrimination, and temporal prediction tasks (Waters & Jablensky 2009;Takeda et al 2017;Ueda et al 2018). Losak and his colleagues (2016) examined brain activity during a predictive timing task, which would concern the temporal updating system, in patients with schizophrenia.…”
