Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The proposed research will test the hypothesis that objective social isolation and loneliness are linked to neurobehavioral mechanisms involved in social perception and motivation in individuals with and without serious mental illness. Moreover, it will investigate the specific dynamic interactions among these experiences in daily life and how they, and their neurobehavioral predictors, are linked to day-to-day functioning. The findings of this project could provide novel targets for therapeutics aimed at improving functioning and overall quality of life in individuals with serious mental illnesses, as well as quantitative phenotypes for use in early detection efforts.
