Comparing the performance of patients with bipolar disorder in the cognitive-behavioral foraging task with healthy individuals

Abstract

Bipolar disorder or manic-depressive disorder is a chronic, severe and mostly recurring mood disorder. The clinical manifestations of this disease are very diverse. Foraging is actually the ability of humans and all animals to survive and reproduce. Various cognitive-behavioral tasks have been designed to investigate this theory in humans. The objective of present study was to compare the performance of patients with bipolar disorder and healthy individuals in a cognitive-behavioral task of Foraging. Methods: Based on the criteria, patients with bipolar disorder and the control group participated in the Foraging task, and the resulting data were stored in the MATLAB programming platform. The behavior and responses of both groups were modeled using the GLMM model, and the differences between them were examined. Findings: According to the results of statistical analysis, search value and offer value can model the decision logic of both groups. In the first and second model, a larger search value led to engage and a larger offer value led to forage, which was completely opposite among all participants. Also, reaction time is longer in patients with bipolar disorder.
