Official title
Using the Brain to Reveal Mental Representations of Subjective Connection
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Nearly half of the U.S. population sometimes or always experiences loneliness, which is alarming given that loneliness confers risk for negative mental and physical health outcomes. Extensive research suggests loneliness is characterized by subjective isolation: many lonely individuals maintain a number of relationships but still report feeling lonely. The goal of this proposal is to use functional magnetic resonance imaging to reveal how the brain represents our subjective connection to and isolation from other people, which will ultimately inform optimal ways to intervene to reduce loneliness.
