The results of the research titled “Dynamics of Retrospective Timing,” designed and conducted by the Department of Psychiatry, Faculty of Medicine, Mental Health and Hospital, Üsküdar University, have been published. The most accurate estimates were obtained in predicting events of 15 minutes in length.
In the survey, which investigated retrospective timing performance (5-90 minutes) with 24,500 participants, participants were asked to decide how long it took them to complete a series of questionnaires at their own pace. Participants estimated the survey durations as more or less than the actual time when the durations were shorter or longer than 15 minutes, respectively. Furthermore, the most accurate estimates were obtained in predicting events of 15 minutes in length.
Researchers, including Prof. Dr. Gökben Hızlı Sayar and Assoc. Prof. Dr. Hüseyin Ünübol, found that as time intervals changed, the variability among subjects in duration estimates exponentially decreased as a function of time, reaching an asymptote after 30 minutes. Finally, in the study published in Psychonomic Bulletin & Review, a significant portion of participants showed an integer bias by rounding their duration estimates to multiples of 5 minutes.
Scope of the "Dynamics of Retrospective Timing" Research
While most interval timing research is tested over multiple trials, participants were explicitly asked to pay attention to time and focus on prospective timing estimates.
Prof. Dr. Gökben Hızlısayar, Psychiatrist and Rector's Advisor at the Department of Psychiatry, Faculty of Medicine, Mental Health and Hospital, Üsküdar University, summarizing the research;
“Our current understanding of interval timing is primarily based on prospective timing. However, most real-life temporal judgments are made without prior knowledge that the durations of events will need to be estimated (i.e., retrospective timing). In the present study, our results provide evidence for systematic biases in retrospective temporal judgments and demonstrate that variability in retrospective timing is relatively higher for shorter durations (e.g., < 30 minutes). Primary findings collected from our dataset have been replicated based on secondary analyses of another dataset (Blursday). This study constitutes the most comprehensive study of retrospective timing concerning the tested duration range and sample size.”
