[Dynamics of time intervals evaluation in heroin addicts]
Abstract:
An evaluation of time perception in drug addicts was carried out in 12 s intervals, using 10 attempts with up to 0.1 s precision. Eighty-two heroin addicts in abstinent and post abstinent periods have been observed, the results being compared to 52 healthy controls. During the first two days after admission to the hospital (abstinent syndrome development), time intervals values were lower in patients than in controls, reaching a precision of recalling 12s, with a following exceeding of this index. On day 15-16, time perception returned to precise level (post abstinent period). Depending on drug addiction duration and individual features of brain hemisphere asymmetry, changes in subjective time perception were revealed in the study.
