Myopic decisions under negative emotions correlate with altered time perception.

Guan S, Cheng L, Fan Y, Li X - Front Psychol (2015)

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: The repeated measures analysis of variance demonstrated that the main effect of emotion on percentages of trials during which SS reward were chosen (SS%) was significant [Figure 2, F(1.11,27.76) = 15.74, p < 0.001, = 0.39]. Paired t-tests showed that compared to neutral priming, negative priming induced much higher SS% [Figure 2, t(25) = 3.86, p < 0.01] while positive priming generated much lower SS% [Figure 2, t(25) = 4.26, p < 0.01], and negative priming led to higher SS% than positive priming did [Figure 2, t(25) = 3.43, p < 0.001]. These data indicated that participants preferred SS reward to delayed reward in negative emotional context, which led to myopic behaviors.
