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.

The stimulus sequences and experimental design. (A) Inter-temporal choice task. A fixation was displayed at the center of screen, which followed by an IAPS picture for 1.5 s. Then, participants should make their choices between a smaller-but-sooner (SS) reward and a larger-but-later (LL) reward within 3 s by key-pressing of “F” for SS or “J” for LL. RN represents SS reward, RL indicates LL reward. (B) Time reproduction task: A fixation was displayed at the center of screen, which followed by an IAPS picture for 1.5 s. After a black screen for 0.3 s, a cycle stimulus as the standard stimulus (duration of 1,2, or 4 s) was presented which was followed by another black screen with duration of 0.4, 0.6, or 0.8 s. Then, the square stimulus appeared as a target, subjects were asked to press “F” in the keyboard (e.g., “F” key) as soon as they thought the duration of target stimuli was the same with standard stimulus. (C) Go/NoGo task: A fixation was displayed at the center of screen, which followed by an IAPS picture for 1.5 s. Then, either Go stimulus (e.g., green circle. Frequency, 70%) or NoGo stimulus (e.g., red circle. Frequency, 30%) was presented with duration of 0.4 s. Participants were asked to respond to either a Go stimulus by pressing “F” in the keyboard as soon as possible or a NoGo stimulus by withholding their response.

Mentions: Each participant had to perform an IC task, a time reproduction task and a Go/NoGo task in current study. The order of the time reproduction task and the Go/NoGo task was counterbalanced across participants. All tasks were programmed in the E-Prime 2.0 (Psychology Software Tools inc. Pittsburgh, PA, USA).
