Myopic decisions under negative emotions correlate with altered time perception.

Bottom Line: Moreover, such overestimation was negatively correlated with performance in the IC task.In contrast, temporary changes of emotional contexts did not alter performances in a Go/NoGo task (including commission errors and omission errors).In sum, our present findings suggested that myopic decisions under negative emotions were associated with altered time perception but not response inhibition.

ABSTRACT
Previous studies have obtained inconsistent findings about emotional influence on inter-temporal choice (IC). In the present study, we first examined the effect of temporary emotional priming induced by affective pictures in a trial-to-trial paradigm on IC. The results showed that negative priming resulted in much higher percentages of trials during which smaller-but-sooner reward (SS%) were chosen compared with positive and neutral priming. Next, we attempted to explore the possible mechanisms underlying such emotional effects. When participants performed a time reproduction task, mean reaction times in negative priming condition were significantly shorter than those in the other two emotional contexts, which indicated that negative emotional priming led to overestimation of time. Moreover, such overestimation was negatively correlated with performance in the IC task. In contrast, temporary changes of emotional contexts did not alter performances in a Go/NoGo task (including commission errors and omission errors). In sum, our present findings suggested that myopic decisions under negative emotions were associated with altered time perception but not response inhibition.

Mentions: First, we computed the Tcorrected scores in different conditions (duration × emotion). Then we examined differential influences of emotion on time reproduction by the repeated measures analysis of variance. We found a significant main effect of emotion [Figure 3A, F(2,50) = 3.46, p = 0.04, = 0.12] and no main effect of duration [F(1.50,37.50) = 2.60, p > 0.05, = 0.09]. However, there was a significant interaction between duration and emotion [F(4,100) = 3.84, p < 0.01, = 0.13]. Thus, we performed further repeated measures analysis of variance and noticed an emotional effect when participants reproduced 1-s-duration [Figure 3B, F(2,50) = 6.15, p < 0.01, = 0.18]. Tcorrected scores were considerably smaller in negative priming compared with neutral [Figure 3B, t(25) = 2.75, p < 0.05, paired t-test] and positive priming [Figure 3B, t(25) = 3.39, p < 0.01, paired t-test], no difference was found between neutral and positive priming [Figure 3B, t(25) = 0.43, p > 0.05, paired t-test]. There was no main effect of emotion on Tcorrected scores when participants reproduced 2-s-duration [Figure 3B, F(2,50) = 0.07, p > 0.05, = 0.01] and 4-s-duration [Figure 3B, F(2,50) = 1.13, p > 0.05, = 0.04].
