        In psychophysics domain, various factors have been studied as the main account of the time contraction after stimulus repetition and the time expansion after a novel stimulus; however, there is no clear explanation about the amount of involvement of temporal and non-temporal features. In this study, 48 sub-jects participated in 3 experiments in which the purer role of temporal properties of stimului were examined. Data were provided by a tem-poral oddball paradigm and the analysis was implemented by repeated measures analysis of variance in experiments 1 and 3. In experiment 2, a psychometric function was used to deter-mine the modified estimations in temporal pro-cessing system. Findings showed that despite removing the non-temporal change in expe-riment 1, the temporal change between repea-ted/non-repeated stimuli can produce time con-traction and dilation respectively. The result was only for the auditory system. In experi-ment 2, an efficient threshold for temporal oddball was suggested. Using the updated threshold, experiment 3 revealed concordant repeated/non-repeated effects on time percep-tion in both modalities. Manuscript profile

        Abstract: The present study was conducted with the aim of investigating the effect of inhibitory control cognitive rehabilitation on hot executive functions: risky decision making and time perception in children with attention deficit/hyperactivity disorder. The research design was semi-experimental with a pre-test, post-test and follow-up with a control group. The statistical population includes male and female students between 7 and 12 years old in elementary schools of Tehran in the academic year 2020-2021 who were suffering from attention deficit/ hyperactiv ity disorder. Among them, 30 students were selected by purposeful sampling method and randomly placed in the experimental and control groups. The SNAP-IV Questionnaire, the Computerized Task Risk Analogue Balloon (BART) and the Time Reproduction Computer Task were used to collect information. For data analysis, using SPSS24 software, variance analysis method with repeated measurements was used. The results showed that there is difference in the perfor-mance of the experimen tal group and the control group in the components of: risky decision making and time perception for long-term intervals (P<0.05). However, compared to the control group, no significant difference was shown between the time reproduction component for short-term intervals in the experimental group. According to the results structured games aimed at enhancing interference inhibition and responding can improve hot executive functions, risky decision making and time perception (long-term intervals) in students with attention-deficit/hyperactivity disorder.
