TLDR
Symptoms include changes in drive and volition lack of motivation, social withdrawal, reduction in spontaneous speech, and alterations in neurocognition difficulties in memory, attention and executive functioning.Abstract:
Symptoms include: •positive-symptom dimension: psychosis hallucinations and delusions •negative-symptom dimension: changes in drive and volition lack of motivation, social withdrawal, reduction in spontaneous speech •cognitive-symptom dimension: alterations in neurocognition difficulties in memory, attention and executive functioning •affective dimension: affective dysregulation giving rise to depressive and manic (bipolar) symptoms (van Os & Kapur, 2009)read more

Temporal processing dysfunction in schizophrenia
Christine A. Carroll,Jennifer M. Boggs,Brian F. O'Donnell,Brian F. O'Donnell,Anantha Shekhar,Anantha Shekhar,William P. Hetrick,William P. Hetrick +7 more
TL;DR: These findings correlated with parameter estimates obtained from a quantitative model of time estimation, and provide evidence of a fundamental deficit in temporal auditory precision in schizophrenia.

Timing dysfunctions in schizophrenia span from millisecond to several-second durations.
Christine A. Carroll,Brian F. O'Donnell,Brian F. O'Donnell,Anantha Shekhar,Anantha Shekhar,William P. Hetrick,William P. Hetrick +6 more
TL;DR: Assessing both millisecond and several-second duration estimates in schizophrenia using a well-established task of time perception provided evidence for a fundamental timing deficit in schizophrenia that may be independent of the length of the to-be-timed duration.

Timing dysfunctions in schizophrenia as measured by a repetitive finger tapping task.
Christine A. Carroll,Brian F. O'Donnell,Brian F. O'Donnell,Anantha Shekhar,Anantha Shekhar,William P. Hetrick,William P. Hetrick +6 more
TL;DR: Findings support the contention that schizophrenia is associated with a broad range of timing difficulties, including those associated with time perception as well as time production.

Altered time-perception performance in individuals with high schizotypy levels.
Phil Reed,Jordan Randell +1 more
TL;DR: Results showed that high scorers on the Unusual Experiences subscale of the O-LIFE(B) estimated the mid point of the stimulus range to be at a significantly longer interval than low scorers, consistent with the notion of altered time-perception for high schizotypals.
