Loneliness and implicit attention to social threat: A high-performance electrical neuroimaging study

摘要: Prior research has suggested that loneliness is associated with an implicit hypervigilance to social threats-an assumption in line the evolutionary model of indicates feeling socially isolated (or on perimeter) leads increased attention and surveillance world unwitting focus self-preservation. Little known, however, about temporal dynamics for threat (vs. nonsocial threat) lonely brains. We used high-density electrical neuroimaging a behavioral task including (and neutral) pictures investigate brain processing vs. stimuli participants (N = 10), compared nonlonely individuals 9). The present study provides evidence images are differentiated from more quickly (~116 ms after stimulus onset) than (~252 That speed accord loneliness. Brain source estimates expanded these results by suggesting (but not nonlonely) showed early recruitment areas involved self-representation.
