Loneliness corresponds with neural representations and language use that deviate from shared cultural perceptions

Area of Science:

• Social Psychology
• Neuroscience
• Cultural Studies

Background:

• Loneliness is characterized by a feeling of social isolation and a lack of shared perceptions.
• The zeitgeist represents the prevailing attitudes and beliefs within a culture.
• A key question is whether loneliness correlates with a divergence from these shared cultural views.

Purpose of the Study:

• To investigate if loneliness is associated with deviations from the cultural zeitgeist.
• To examine the neural and linguistic correlates of this potential disconnection.

Main Methods:

• Two brain imaging studies (N=40 each) analyzed neural representations of celebrities in lonely versus non-lonely individuals.
• A large-scale study (N=923) examined the language used by lonely individuals to describe celebrities, particularly when strong group consensus existed.

Main Results:

• Lonely participants showed distinct neural representations of celebrities in the medial prefrontal cortex, deviating from group consensus.
• Lonelier individuals employed more idiosyncratic language when describing celebrities, especially in contexts with a strong cultural consensus.

Conclusions:

• Findings support the subjective experience of lonely individuals feeling that their views are not shared.
• Loneliness may encompass a disconnection from prevalent cultural perceptions, not solely a lack of individual relationships.
