自动化情绪调节中存在积极效应吗:来自ERPs的证据

Is There the Positive Effect in Automatic Emotion Regulation:Evidence from An Emotional Cued Go/Nogo Task

采用线索Go/Nogo任务,运用ERPs技术考察了老年人和青年人在自动化情绪调节上的差异。ERPs结果显示:⑴愉快面孔比中性面孔诱发的Go-N2波幅较小,潜伏期较短;Nogo-P3波幅较大,潜伏期较短,表明情绪面孔比中性面孔更能吸引注意;⑵在愉快面孔上,老年组比青年组的Go/Nogo-P3波幅大、潜伏期差异不显著;在悲伤面孔上,老年组比青年组的Go/Nogo-P3波幅大,Nogo-P3潜伏期长,说明老年组比青年组更加抑制对悲伤面孔的反应,老年人在自动化情绪调节中表现出一定程度的积极效应。

In order to investigate whether there is automatic emotion regulation （AER） in a cued G0/Nogo task and whether there is any positive effect in AER, the present study used the event-related potentials iERPs） technique to study the aging effect of AER in judging the gender of emotional faces in an emotional cued Go/Nogo task. Participants （12 right-handed older adults and 12 rigilt-handed younger adults） were asked to discriminate the gender of a happy, neutral, or sad face presented at the center of the computer Screen. These emotionai faces were selected from IAPS （International Affective Picture System, lAPS）. Based on previous studies, the N2 and P3 components of the subset of sites including frontal （F3, FZ, F4）, frontal-central （FC3, FCZ, FC4） and central （C3, CZ, C4） electrode sites were assessed. The peak amplitudes and latencies were measured automatically between 250ms and 350ms and between 350ms and 700ms for the N2 and P3, respectively. For each stimulus type, repeated ANOVA was Used to analyze these measures.
