“…This lengthening effect is also entirely consistent with findings on fear conditioning in animals (e.g. Brown, Richer & Doyère, 2007;Meck, 1983) and human adults using electric shocks or aversive sounds (Droit-Volet, Mermillod, Cocenas & Gil, 2010a;Falk & Bindra, 1954;Hare, 1963). For example, Droit-Volet et al (2010a) showed that the expectation of a fearful sound (50-ms burst of 95-dB white noise) that hurts the ears and produces a defensive startle reflex shifts the psychophysical function toward the left in a temporal bisection task, compared with that of a non-aversive sound (50-ms beep), or no sound, consistent with a fear-related temporal lengthening effect (Fig.…”

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.

“…Consequently, presenting an emotionally arousing stimulus during reproduction may distract subjects from the dimension of time leading to overestimation during reproduction. Brown et al (2007), using a similar procedure, found that rats’ responses to fearful stimuli led to overestimations during reproduction and Aum et al (2004) demonstrated similar effects when pigeons were presented with a positive food reward during production trials. Combined these results demonstrate that positive and negative stimuli may sometimes be overestimated during reproduction because they distract attention from the non-emotional details, including time.…”

“…If a condition continuously alters attention allocation towards time, the distortions in timing will be proportional to the cue duration (e.g., a 10% effect on pulse accumulation will result in a 10% change in subjective duration for all intervals — Droit-Volet et al, 2004; Effron et al, 2006). In contrast, if switch latency were altered, this would affect all target durations by the same absolute amount (Brown et al, 2007; Lejeune, 1998). …”

Effects of Emotional Valence and Arousal on Time Perception

We examined the influence of emotional arousal and valence on estimating time intervals. A reproduction task was used in which images from the International Affective Picture System served as the stimuli to be timed. Experiment 1 assessed the effects of positive and negative valence at a moderate arousal level and Experiment 2 replicated Experiment 1 with the addition of a high arousal condition. Overestimation increased as a function of arousal during encoding of times regardless of valence. For images presented during reproduction, overestimation occurred at the moderate arousal level for positive and negative valence but underestimation occurred in the negative valence high arousal condition. The overestimation of time intervals produced by emotional arousal during encoding and during reproduction suggests that emotional stimuli affect temporal information processing in a qualitatively different way during different phases of temporal information processing.

“…Interestingly, an over-reset strategy has been previously reported only when rodents were presented with emotionally-charged distracters (e.g., stimuli previously paired with footshock) [13, 14], but not by manipulating the intensity of a neutral noise distracter [15]. To date, this is the first study in which mice have been tested with various distracters, and the first report of an over-reset after an interruption by neutral stimuli.…”

“…However, presentation of novel neutral distracters during the uninterrupted to-be-timed stimulus considerably delays responding, suggesting rats fail to devote attentional resources to timing, do not retain the pre-gap interval in working memory, and restart timing after the distracter, using a “reset” mode [reviewed in 12]. Moreover, emotional distracters (e.g., previously paired with footshock) delay timing much longer than a reset [13, 14], suggesting that rats fail to switch attentional resources back to timing long after the end of the distracter, in an “over-reset” mode. To date, no “over-reset” has been reported following neutral distracters.…”

Interval timing is crucial for decision-making and motor control and is impaired in many neuropsychiatric disorders. Previous studies examined timing in various strains or genetically-altered mice, but not in parallel in male and female mice in the same experimental setting. We investigated timing and attention to time in male and female C57Bl/6J mice, when presented with gaps in the timed stimulus, novel auditory distracters presented during the un-interrupted timed stimulus, and gap+distracter combinations. No sex differences were found in regard to timing accuracy and precision. However, presentation of the gap+distracter combination over-reset timing in males but had a much smaller effect in females. The over-reset strategy was reported previously with emotional distracters (e.g., previously paired with footshock) but not with neutral distracters. These results reveal sex differences in attentional gating/switching or working memory for time.
