What are the motivational underpinnings of solitude? We know from self-report studies that increases in solitude are associated with drops in approach motivation and rises in avoidance motivation, but only when solitude is experienced as non-self-determined (i.e., non-autonomous). However, the extent to which individual differences in solitude relate to neurophysiological markers of approach–avoidance motivation derived from resting-state electroencephalogram (EEG) is unknown. These markers are Frontal Alpha Asymmetry, beta suppression, and midline Posterior versus Frontal EEG Theta Activity.

我脑子里有一场聚会，没有人被邀请：静息状态下的皮层活动和孤独

孤独的动机基础是什么？我们从自我报告研究中得知，孤独的增加与接近动机的下降和回避动机的上升有关，但只有当孤独被体验为非自我决定（即非自主）时。然而，孤独中的个体差异与来自静息态脑电图（EEG）的趋避动机的神经生理学标志物的相关程度尚不清楚。这些标记是额叶 Alpha 不对称、β 抑制以及中线后部与额叶脑电图 Theta 活动。
