NIH-funded research R21 grant

Understanding how uncertainty affects mental health

Official title: Quantifying the cognitive processes supporting computations of stochasticity and volatility in humans

Funded at University of Southern California · NIH-10843239 · Data updated 2026-11-12

This study is looking at how people with anxiety and schizophrenia think about uncertainty, by seeing how their brains react to different kinds of confusing information, and it aims to help us understand these feelings better so we can find better ways to support those who experience them.

Who could benefit from this research

Could help

Ideal candidates for this research include individuals experiencing anxiety disorders or other mental health issues related to uncertainty.

Less likely to help

Patients with stable mental health and no history of anxiety or related disorders may not benefit from this research.

What this research studies

This research investigates the cognitive processes that contribute to feelings of uncertainty in individuals with mental health disorders such as anxiety and schizophrenia. By examining how the brain processes different types of noise in observations, the study aims to identify specific computational mechanisms that may lead to cognitive dysfunctions. Participants will engage in a novel task designed to assess their responses to varying levels of uncertainty over time, providing insights into how these processes can differ among individuals. The findings could help clarify the relationship between uncertainty and mental illness, potentially leading to improved treatment strategies.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and treatment options for individuals suffering from anxiety and other mental health disorders.

How similar studies have gone: Previous research has shown promising results in understanding cognitive processes related to uncertainty, suggesting that this approach could yield valuable insights.
