To anticipate other people’s behavioral intentions and respond to them at the right moment is crucial for efficient social interaction. In the present study, we thus investigated how adults synchronize with emotional facial expressions. The participants had to synchronize their taps with a rhythmical sequence of faces and then continue tapping at the same rhythm without faces. Three inter-stimulus intervals (500, 700, and 900 ms) and six different facial expressions (disgust, neutrality, sadness, joy, anger, and fear) were tested. In the synchronization phase, no difference was observed between the different facial expressions, suggesting that the participants tap in synchrony with external rhythms in the presence of stimuli whatever their emotional characteristics. However, in the continuation phase, an emotion effect emerged, with the individual rhythms being faster for the facial expressions of fear and, to a lesser extent, anger than for the other facial expressions. The motor rhythms were also longer and more variable for the disgusted faces. These findings suggest that the internal clock mechanism underlying the timing of rhythms is accelerated in response to the high-arousal emotions of fear and anger.

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.
