Abstract

Social rejection can create powerful changes in people's brains and bodies. In the study reported here, we examined brain-based individual differences associated with buffering against cardiovascular threat responses to social rejection. Using EEG source-localization techniques, we examined differences in intracortical asymmetry. We predicted that individuals with greater left relative to right dorsolateral prefrontal activity would show a more approach-motivated response to social rejection. Eighty-four female participants were randomly assigned to one of three stressful situations: social rejection, social evaluation without rejection, or self-evaluation. Among participants assigned to the social-rejection condition, greater left relative to right prefrontal intracortical activity at baseline was associated with more adaptive cardiovascular profiles and more self-reported approach-oriented emotions. Participants in the other conditions did not show these relationships. Our data are the first to show that social context matters when attempting to link individual differences in cortical asymmetry with approach-related cardiovascular and emotional outcomes.

  • Individuals with higher left, relative to right, frontal cortical activity were more likely to respond to acute stress with challenge appraisals and challenge reactivity (higher CO and lower TPR).

    “Specifically, individuals with higher left, relative to right, frontal cortical activity (a neurological pattern previously linked to positive affect and well-being) were more likely to respond to acute stress with challenge appraisals and challenge reactivity (higher CO and lower TPR; Koslov et al., 2011), suggesting a direct relationship between resting neurological activity and cardiovascular”

    The Results report that greater resting left frontal asymmetry predicted higher cardiac output and lower total peripheral resistance, but only during social-evaluative threat. The paper measured demand and resource appraisals, yet the passages do not show that left frontal asymmetry predicted more challenge appraisals; they report appraisal differences between experimental conditions instead. The claim also broadens a finding from social rejection in female participants to acute stress generally. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
