不同情绪图片对正常大学生时间感知的影响

Influence of different affective pictures on time perception in normal college students

目的研究不同情绪图片对正常大学生时间感知的影响。方法经过抑郁自评量表(SDS)和焦虑自评量表(SAS)筛选出74名正常大学生,每名学生都给予情绪图片影响时间感知的神经心理学测验,比较情绪图片的不同维度对时间感知的影响。结果情绪图片的愉悦度和唤醒度对时间感知均有影响[愉悦度,F(2,438)=60.58,P<0.001];唤醒度,F(1,438)=8.74,P<0.005];在唤醒度相似的情况下,被试感知正性图片的时间短于中性图片,感知负性图片的时间长于中性图片;在愉悦度相似的情况下,被试感知高唤醒图片时间长于低唤醒图片。结论情绪会影响人们的时间感知,时间可以随着人们心情的改变变得快或者慢。

Objective To investigate the influence of different affective pictures on time perception in normal college students,and to try to find out how emotions affect our time perception.Methods Choosing 74 normal college students through Self-Rating Depression Scale （SDS） and Self-Rating Anxiety Scale （SAS）,then we gave every student neuropsychological test about affective pictures′ influence to the time perception,compared with the influence of affective factors on time perception.Results Both value and arousal of affective pictures on the time perception were signification [value,F（2,438）=60.58,P〈0.001];arousal,F（1,438）=8.74,P〈0.005];for similar arousal stimuli,the duration of positive slides were judged shorter than the duration of neutral slides,while negative ones were longer than neutral ones;for similar value stimuli,the high arousal slides were judged relatively longer than the low arousal slides.Conclusion Emotion may affect people′s time perception,time may be longer or shorter than itself in according with different mood of people.
