arousal. Heart rate, a key marker for arousal, has been shown to slow down during disgusting experiences [64] and thus the temporal underestimation of disgusting images could be due to pacemaker rate decreasing and fewer temporal pulses being accumulated. Given that these interpretive difficulties do not apply to the present work, it can be considered a meaningful extension of the literature on emotion, attention, and time. Conclusion The present set of experiments demonstrates that individuals underestimate the duration of a neutral stimulus if that stimulus is presented in an emotional as compared to neutral context. This is true regardless of whether the emotion is positive or negative suggesting that both positive and negative experiences can affect timing in similar ways.

In: Emotion Effects on Timing unlikely to involve the pacemaker, but instead may arise from a modulation of attention. If true, this would lend a parsimonious explanation of why emotions can both slow down and speed up everyday experiences. A slowing down of perceived time may occur when individuals wish for an experience to end quickly and hence direct resources towards monitoring the passing of time. In contrast, a speeding up of time occurs when the experience captures attention leaving the passing of time unnoticed and leading us to believe that ‘‘time flies’’.
