Frontal EEG asymmetry, relatively greater left-than-right frontal activity (rLFA), has been associated with mood symptoms and approach versus withdrawal behaviors. Distress tolerance (DT), a transdiagnostic behavior, has yet to be examined as an approach behavior using rLFA. Adolescents (N = 20; M age = 14.53, SD = 2.09) completed a frustrating mirror-tracing task which provided an index of DT. Higher resting rLFA was associated with lower DT. The results are the first to identify a relationship between cortical activation and distress tolerance in adolescents. rLFA appears to be a neurophysiological index of behaviors associated with approach motivation and escape from punishment or aversive situations.
额 EEG 不对称,即左额区活动相对大于右额区(rLFA),与情绪症状以及趋近和回避行为有关。痛苦耐受力(DT)作为一种跨诊断行为,尚未使用 rLFA 作为趋近行为进行研究。本研究纳入 20 名青少年(M 年龄=14.53,SD=2.09),他们完成了一项令人沮丧的镜像追踪任务,该任务提供了 DT 的指标。静息状态下 rLFA 较高与 DT 较低相关。研究结果首次确定了青少年皮质激活与痛苦耐受力之间的关系。rLFA 似乎是与趋近动机以及逃避惩罚或厌恶情境相关行为的神经生理指标。
