Abstract

Loneliness is the distressing feeling associated with the perceived absence of satisfying social relationships. Loneliness is increasingly prevalent in modern societies and has detrimental effects on health and happiness. Although situational threats to social relationships can transiently induce the emotion of loneliness, susceptibility to loneliness is a stable trait that varies across individuals [6-8] and is to some extent heritable. However, little is known about the neural processes associated with loneliness (but see [12-14]). Here, we hypothesized that individual differences in loneliness might be reflected in the structure of the brain regions associated with social processes. To test this hypothesis, we used voxel-based morphometry and showed that lonely individuals have less gray matter in the left posterior superior temporal sulcus (pSTS)--an area implicated in basic social perception. As this finding predicted, we further confirmed that loneliness was associated with difficulty in processing social cues. Although other sociopsychological factors such as social network size, anxiety, and empathy independently contributed to loneliness, only basic social perception skills mediated the association between the pSTS volume and loneliness. Taken together, our results suggest that basic social perceptual abilities play an important role in shaping an individual's loneliness.

  • Severe and persistent feelings of loneliness impair executive functioning, heighten sensitivity to negative social stimuli, and erode interpersonal trust.

    “severe and persistent feelings of loneliness have been shown to impair executive functioning, heighten sensitivity to negative social stimuli, and erode interpersonal trust [for a review, see 29].”
  • This finding is consistent with the important role that maladaptive social cognition is believed to play in the initiation and maintenance of loneliness.

    “This finding is consistent with the important role that maladaptive social cognition is believed to play in the initiation and maintenance of loneliness [29].”
  • Transient feelings of loneliness may motivate individuals to reconnect with others, whereas prolonged loneliness increases withdrawal and cognitive vigilance to social threat.

    “Whereas transient feelings of loneliness may motivate individuals to reconnect with other individuals, prolonged loneliness increases withdrawal and cognitive vigilance to social threat [29].”

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.
