This study on metacognition of time examined the confidence judgment in the temporal generalization task when the difficulty of temporal discrimination increased, in three different standard duration conditions. The results showed that participants’ confidence judgments were accurate for all comparison durations similar to the standard duration and varied only for the comparison durations shorter or longer than the standard duration. The confidence judgment did not change with the standard duration condition; except for an overconfidence level for the comparison durations longer than the standard in the shortest standard duration condition. Moreover, the results showed that the overconfidence level increases with the increase in temporal discrimination difficulty, although an underconfidence level was found but only for the shortest comparison durations. The implication in terms of decision processes for the generalization temporal task and in terms of metacognitive processes are discussed. [less ▲]

When speaking about ageing in place, risk of accidents and subsequent injuries is an important part of individual worries, and risk avoidance or risk minimisation are main concerns of older people and their caregivers. Findings show that older people are more at risk of unintended injuries than younger people (i.e. falls, foodborne diseases). Moreover, individual concerns and associated worries to avoid specific risks may even lead to the decision to move to an institution. In this context it is important to consider that being “as safe as possible” with respect to objective parameters does not necessarily indicate the subjective feeling of being safe. The feeling of safety and the objective degree of safety are not linearly related in a way that increasing one factor will increase the other and conversely. Furthermore, some factors that can contribute to objectively enhance safety may even lead to greater feeling of unsafety. Our review aims to investigate the relationship between objective and subjective safety in the context of ageing in place as well as the underlying mechanisms that help to explain the different links between objective and subjective safety. A further goal is offer a heuristic model presenting factors that may help to enhance older people’s consciousness of safety and thus quality of life. These include individual as well as social and macro-social factors. This paper focusses individual factors and will especially highlight the role of older people’s daily routines and their impact on technology acceptance. [less ▲]

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 ▲]

Metacognition concerns both individuals' knowledge about their cognitive functioning and the processes that regulate them (Koriat, 2007). The study of the perception of time showed that many factors cause temporal distortions, including, for example, attention or feedback. The purpose of this work is thus to propose an integrative model of metacognition of time perception; i.e. to integrate data based on conventional research on the perception of time in a metacognitive model (Nelson and Narens 1990). Our first question was to verify the existence of knowledge about the perception of time, especially on the factors responsible for temporal distortions. The three experiments of our first study led us to create and validate the Metacognitive Questionnaire on Time (MQT). The latter consists of 24 items that highlights the existence of knowledge, more reliable for oneself (subscale Self, 12 items) than for others (subscale Others, 12 items), on two factors known to affect time perception: an Emotion Factor (4 items) and an Attention factor (8 items). Secondly, we studied the influence of metacognitive processes on temporal judgments. Thus, we are interested in the influence of metacognitive Control process on performances in two temporal tasks. Our hypothesis was that knowledge about time allowed regulating the temporal judgments. The results of our studies (Study 2 and 3, respectively composed of one and two experiments) confirmed the importance of the Control process on temporal judgments. Thus, mere awareness of the role of attention on perception of time causes a reduction of the attentional effect generally observed (Study 2). Moreover, explicit erroneous knowledge given to participants causes a reduction or even disappearance of automatic emotional effect of anger on the temporal judgments (Study 3). Finally, we have explored the link between Monitoring process and temporal judgments. Our fourth study demonstrated the ability of individuals to accurately estimate the accuracy of their temporal judgments under certain conditions. Indeed, it appears that individuals are sensitive to task difficulty and duration range. These two dimensions affect both temporal judgments and confidence level estimates. Overall, the results of this study emphasize the importance to take account of metacognitive processes in the study of the perception of time. [less ▲]

abstract This study examined how the awareness of emotion-related time distortions modifies the effect of emotion on time perception. Before performing a temporal bisection task with stimulus durations presented in the form of neutral or emotional facial expressions (angry, disgusted and ashamed faces), some of the participants read a scientific text providing either correct or incorrect information on the emotion–time relationship. Other partici- pants did not receive any information. The results showed that the declarative knowledge allowed the participants to regulate (decrease) the intensity of emotional effects on the perception of time, but did not trigger temporal effects when the emotional stimuli did not automatically induce emotional reactions that distorted time.

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 past few decades have seen an explosion in studies exploring the effects of emotion on time judgments. The aim of this review is to describe the results of these studies and to look at how they try to explain the time distortions produced by emotion. We begin by examining the findings on time judgments in affective disorders, which allow us to make a clear distinction between the feelings of time distortion that originate from introspection onto subjective personal experience, and the effects of emotion on the basic mechanisms involved in time perception. We then report the results of behavioral studies that have tested the effects of emotions on time perceptions and the temporal processing of different emotional stimuli (e.g. facial expressions, affective pictures or sounds). Finally, we describe our own studies of the embodiment of timing.Overall, the different results on time and emotion suggest that temporal distortions are an indicator of how our brain and body adapt to the dynamic structure of our environment.

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 ▲]
