- Abstract
Wariness in early childhood manifests as shy, inhibited behavior in novel social situations and is associated with increased risk for developing social anxiety. In youth with childhood wariness, exposure to a potent social stressor, such as peer victimization, may potentiate brain-based sensitivity to unpredictable social contexts, thereby increasing risk for developing social anxiety. To test brain-based associations between early childhood wariness, self-reported peer victimization, and current social anxiety symptoms, we quantified neural responses to different social contexts in low- and high-victimized pre-adolescents with varying levels of early childhood wariness. Measures of early childhood wariness were obtained annually from ages 2-to-7-years. At age 11, participants were characterized as having low (N = 20) or high (N = 27) peer victimization. To index their neural responses to peer evaluation, participants completed an fMRI-based Virtual School paradigm (Jarcho et al. Developmental Cognitive Neuroscience, 13, 21-31, 2013a). In highly victimized, relative to low-victimized participants, wariness was differentially related to right amygdala response based on the valence and predictability of peer evaluation. More specifically, in highly victimized participants, wariness was associated with greater right amygdala response to unpredictably positive peer evaluation. Effects of wariness were not observed in participants who reported low levels of victimization. Moreover, in victimized participants, high wariness and right amygdala response to unpredictably positive peer evaluation was associated with more severe social anxiety symptoms. Results can be interpreted using a diathesis-stress model, which suggests that neural response to unexpectedly positive social feedback is a mechanism by which exposure to peer victimization potentiates the risk for developing social anxiety in individuals exhibiting high levels of early childhood wariness.
