 Results indicated significant correlations between Time perception tasks and memory outcomes suggesting such impairments are directly related to memory impairment in schizophrenia.Schizophrenia has been associated with abnormalities in dopamine (DA) transmissions (Seeman et al., 2006), which in turn, have been linked to the speed of the internal clock (Cheng et al., 2007).The time overestimation has been suggested to be caused by accelerated time processing and may be associated with psychosis (Droit-Volet and Meck, 2007)
