This study examined the difference in the perception of time between young and older adults in a temporal bisection task with four different duration ranges from a few milliseconds (500 ms) to several seconds (30 s). In addition, individual cognitive capacities (short-term memory, working memory, processing speed, attention) were assessed with different neuropsychological tests. The results showed a general effect of age on the variability of time judgment, indicating a lower sensitivity to time in the old than in the younger adults, regardless of the duration range tested. In addition, the results showed that the individual differences in time sensitivity were explained by attention capacities, which decline with aging. [less ▲]

The aim of our studies was to design a Metacognitive Questionnaire on Time (MQT) that assesses inter-individual variations in the awareness of factors affecting the experience of the passage of time. In the first study, 532 youngadultswere askedto reply to an initialquestionnaire consistingof 106questions relating to many different factors (e.g., psychostimulant, body temperature, age, attention) that could affect howtime is perceived. Factorial analyses allowed us to extract two discriminant factors, one relating to attention and the other to emotion. The second study sought to validate the final 24-item questionnaire by gathering data from 212 university students. Confirmatory Factorial Analyses (AMOS) showed that the MQT has the same two-factor structure. The third study assessed the construct validity of the MQT by measuring the correlation between theMQT scores and the scores with other questionnaires measuring close or different constructs. In sum, these studies enabled us to develop an easy-to-use questionnairewhereby it is possible to distinguish between individuals according to their subjective feeling of the passage of time. In addition, the participants’ responses on the MQT showed that they were more aware of attention-related factors than of emotion-related factors that might produce time distortions, and thatwomenwere more aware of their own temporal distortions than men.

The perception of time cannot be reduced to a simple percept produced by an internal clock. The aim of the present study was therefore to investigate the role of the individual consciousness of time on temporal judgments. In the present study, the participants’ awareness of attention-related time distortions was assessed using a metacognitive ques- tionnaire. The participants were also required to verbally judge a series of stimulus dura- tions in a single or a dual task condition. The results revealed that time was underestimated in the dual task compared to the single task. However, the accuracy of time judgments improved in line with the participants’ individual awareness of attentional time distortion: The more aware they were of the role of attention in time perception, the lower the time distortions they exhibited. Conscious awareness of time therefore plays a role in the accuracy of the time judgments made by human beings. [less ▲]
