Time flies faster when you’re feeling blue: sad mood induction accelerates the perception of time in a Temporal Judgment task
Cognitive Processing, 2020Co-Authors: Erik M. Benau, Ruth Ann AtchleyAbstract:Investigating the interaction of mood and time perception has provided key information in the mechanisms that underlie cognition and emotion. However, much of the literature that has investigated the role of emotions in time perception has focused on the valence of stimuli, or correlational studies of self-reported mood. In the present study, 31 healthy undergraduates completed a Temporal Judgment task before and after an autobiographical sad mood induction procedure. In the Temporal Judgment task, participants identified whether a presented neutral stimulus was onscreen for the same duration as a target (2 s). Along with target trials, very short (1.25 s), short (1.6 s), long (2.25 s), and very long (3.125 s) trials were presented in random order and in equal proportion. Following mood induction, ratings of sadness and fear increased, but returned to baseline at the end of the study. After the mood induction, participants significantly increased Temporal overestimation as participants were more likely to affirm short than long-duration trials as matching the target. These results indicate that transient changes in mood in otherwise healthy adults can accelerate the subjective experience of time. Sadness may increase physiological components of time perception that are related approach motivation.

Relative contribution of pitch and brightness to the auditory kappa effect
Psychological Research, 2019Co-Authors: Nicolas Marty, Maxime Marty, Micha PfeutyAbstract:Pitch height is known to interfere with Temporal Judgment. This is the case in the auditory kappa effect in which the relative degree of pitch distance separating two tones extends the perceived duration of the inter-onset interval (IOI). However, pitch variations which result from manipulations of the fundamental frequency of tones are associated with variations of the spectral centroid, which is related to the perceived brightness. The present study aimed at determining the relative contribution of pitch and brightness to the auditory kappa effect. Forty-eight participants performed an AXB paradigm (tone X was shifted to be closer to either tone A or B) in three conditions: the three tones varied in both pitch and brightness (PB condition), pitch varied but brightness was fixed (P condition) or brightness varied but pitch was fixed (B condition). Pitch and brightness were modified by manipulating the fundamental frequency ( F 0) and the spectral centroid of the tones, respectively. In each condition, the percentage of trials in which the first IOI was perceived as shorter increased as X was closer (in pitch and/or brightness) to A. Furthermore, the magnitude of the effect was larger in PB than in P condition, while it did not differ between PB and B conditions, suggesting that brightness would contribute more than pitch height to the auditory kappa effect. This study provides the first evidence that auditory brightness interferes with duration Judgment and highlights the importance to consider jointly the role of pitch height and brightness in future studies on auditory Temporal processing.

Distortion of time interval reproduction in an epileptic patient with a focal lesion in the right anterior insular/inferior frontal cortices
Neuropsychologia, 2014Co-Authors: Vincent Monfort, Micha Pfeuty, Madelyne Klein, Steffie Collé, Hélène Brissart, Jacques Jonas, Louis MaillardAbstract:This case report on an epileptic patient suffering from a focal lesion at the junction of the right anterior insular cortex (AIC) and the adjacent inferior frontal cortex (IFC) provides the first evidence that damage to this brain region impairs Temporal performance in a visual time reproduction task in which participants had to reproduce the presentation duration (3, 5 and 7 s) of emotionally-neutral and -negative pictures. Strikingly, as compared to a group of healthy subjects, the AIC/IFC case considerably overestimated reproduction times despite normal variability. The effect was obtained in all duration and emotion conditions. Such a distortion in time reproduction was not observed in four other epileptic patients without insular or inferior frontal damage. Importantly, the absolute extent of Temporal over-reproduction increased in proportion to the magnitude of the target durations, which concurs with the scalar property of interval timing, and points to an impairment of time-specific rather than of non Temporal (such as motor) mechanisms. Our data suggest that the disability in Temporal reproduction of the AIC/IFC case would result from a distorted memory representation of the encoded duration, occurring during the process of storage and/or of recovery from memory and leading to a deviation of the Temporal Judgment during the reproduction task. These findings support the recent proposal that the anterior insular/inferior frontal cortices would be involved in time interval representation.

Similar time distortions under the effect of emotion for durations of several minutes and a few seconds.
Acta Psychologica, 2020Co-Authors: Sylvie Droit-volet, Ahmed El-azhari, Samuel Haddar, Rémi Drago, Sandrine GilAbstract:Similar time distortions under the effect of emotion for durations of several minutes and a few seconds. Acta Psychologica, 210, 103170. (S. Droit-Volet). A B S T R A C T This study examined the effect of emotion on the Judgment of durations of several minutes compared with that of durations of a few seconds. Three experiments were performed on the Temporal Judgment of emotional stimuli lasting from 2 s to 6 min (Experiment 1) or from 2 to 6 min (Experiment 2 and 3). These involved emotional sounds (Experiment 1 and 2) or virtual reality emotional films (Experiment 3). The results showed an increase in the lengthening of the perceived duration as the level of arousal and negative valence of the emotional stimuli increased, both for the long durations of several minutes and for the shorter durations. However, the magnitude of the time distortion tended to decrease as the length of the duration increased because the affects experienced by the participants lost their intensity over time. Nonetheless, when the exposure to emotional stimuli was limited and the stimuli were sufficiently arousing, as in Experiments 2 and 3, people overestimated time across durations ranging from seconds to minutes.

Time Judgments as a Function of Mindfulness Meditation, Anxiety, and Mindfulness Awareness
Mindfulness, 2017Co-Authors: Sylvie Droit-volet, Julien HerosAbstract:The first aim of this study was to examine the differences in time Judgments between meditators, who already possessed mindfulness-oriented meditation experience, and control subjects. The second was to examine the immediate effect of a long mindfulness meditation session (30 min) on the Judgment of short stimulus durations (from 0.8 to 2.0 s). In addition, individual characteristics in terms of cognitive, affective (anxiety, arousal), and mindful awareness were assessed to investigate the relations between time Judgments and individual states. The results showed no difference between the meditators and the controls on the different types of time Judgment. The regular practice of meditation therefore did not change the Judgment of passage of time or the Judgment of short durations. However, the participants with a higher level of mindfulness awareness experienced a slowing down of the passage of time. In addition, the immediate effect of the mindfulness meditation session was to reduce the variability of Temporal Judgment in all participants. This improvement was linked, at least for the longest duration (2.0 s), to the decrease in anxiety and arousal levels as a result of the mindfulness session.

What is the best and easiest method of preventing counting in different Temporal tasks?
Behavior Research Methods, 2012Co-Authors: Anne-claire Rattat, Sylvie Droit-voletAbstract:The aim of the present study was to determine the best and easiest method of suppressing spontaneous counting in a Temporal Judgment task. Three classic methods used to avoid counting—instructions not to count, articulatory suppression, and administration of an interference task—were tested in Temporal generalization, bisection, and reproduction tasks with two duration ranges (1–4 and 2–8 s). All the three no-counting conditions prevented participants from counting, counting leading to estimates that were more accurate and less variable and to violations of the fundamental scalar property of timing. With regard to the differences between the no-counting conditions, the interference task distorted time perception more strongly and increased variability in Temporal estimates to a greater extent than did articulatory suppression, as well as the no-counting instructions condition. In addition, articulatory suppression produced more noise in behavioral outcome than did the no-counting instruction condition. In sum, although all methods have disadvantages, the instructions not to count actually constitute the simplest and more efficient method of preventing counting in timing tasks. However, further studies must now concentrate on the role of explicit instructions in our experience of perception.
