Clinical conditions (e.g., Parkinson\u2019s disease, addictions) that alter dopaminergic signaling have been shown to affect motor timing and perceived duration. The present study aimed at investigating whether the effects of chronic stimulant use on temporal processing are time-interval dependent. All participants performed two different time bisection tasks (480\/1920 ms and 1200\/2640 ms) in which we analysed the proportion of long responses for each stimulus duration as well as an index of perceived duration and one of sensitivity. Regarding the proportion of long responses, we found no differences between groups in either time bisection task but patients had more variable results than controls did in both tasks. This study provides new insight into temporal processing in stimulant-dependent patients. Regardless of the time interval tested, the results showed comparable temporal ability in patients and controls, but higher temporal variability in patients. This finding is consistent with impairment of frontally-mediated cognitive functions involved in time perception rather than impairment in time processing per se.<\/jats:p>","DOI":"10.3390\/brainsci12060745","type":"journal-article","created":{"date-parts":[[2022,6,6]],"date-time":"2022-06-06T10:08:24Z","timestamp":1654510104000},"page":"745","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Time Perception in Cocaine-Dependent Patients"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1212-4591","authenticated-orcid":false,"given":"Giovanna","family":"Mioni","sequence":"first","affiliation":[{"name":"Dipartimento di Psicologia Generale, Universit\u00e0 di Padova, 35131 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naomi","family":"Sanguin","sequence":"additional","affiliation":[{"name":"Dipartimento di Psicologia Generale, Universit\u00e0 di Padova, 35131 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Graziella","family":"Madeo","sequence":"additional","affiliation":[{"name":"Novella Fronda Foundation, 35121 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefano","family":"Cardullo","sequence":"additional","affiliation":[{"name":"Novella Fronda Foundation, 35121 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,6]]},"reference":[{"key":"ref_1","unstructured":"Gibbon, J., and Allan, L.G.
