Emotion effects on timing: attention versus pacemaker accounts.

Lui MA, Penney TB, Schirmer A - PLoS ONE (2011)

Bottom Line: Participants were more likely to judge S2 as shorter than S1 when the intervening picture was emotional as compared to neutral.This effect held independent of S1 and S2 modality (Visual: Exps. 1, 2, & 3; Auditory: Exp. 4) and intervening picture valence (Negative: Exps. 1, 2 & 4; Positive: Exp. 3).Taken together, these findings indicate that emotional experiences may decrease temporal estimates and thus raise questions about the suitability of internal clock speed explanations of emotion effects on timing.

ABSTRACT
Emotions change our perception of time. In the past, this has been attributed primarily to emotions speeding up an "internal clock" thereby increasing subjective time estimates. Here we probed this account using an S1/S2 temporal discrimination paradigm. Participants were presented with a stimulus (S1) followed by a brief delay and then a second stimulus (S2) and indicated whether S2 was shorter or longer in duration than S1. We manipulated participants' emotions by presenting a task-irrelevant picture following S1 and preceding S2. Participants were more likely to judge S2 as shorter than S1 when the intervening picture was emotional as compared to neutral. This effect held independent of S1 and S2 modality (Visual: Exps. 1, 2, & 3; Auditory: Exp. 4) and intervening picture valence (Negative: Exps. 1, 2 & 4; Positive: Exp. 3). Moreover, it was replicated in a temporal reproduction paradigm (Exp. 5) where a timing stimulus was preceded by an emotional or neutral picture and participants were asked to reproduce the duration of the timing stimulus. Taken together, these findings indicate that emotional experiences may decrease temporal estimates and thus raise questions about the suitability of internal clock speed explanations of emotion effects on timing. Moreover, they highlight attentional mechanisms as a viable alternative.

pone-0021829-g004: The group mean probability of responding “shorter” and standard error of the mean are plotted for each S2 duration in Experiment 3.

Mentions: Analysis of the probability of responding “shorter” revealed significant main effects of S2 Duration (F(3, 36) = 54.86, p<.001, η2partial = .821) and Emotion (F(1, 12) = 5.28, p<.05, η2partial = .305). Participants were more likely to respond “shorter” with decreasing S2 duration and when S2 was preceded by a positive as compared to a neutral picture (Fig. 4). S2 Duration and Emotion failed to interact (p>.1).
