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

Abstract

Schizophrenia is a mental disorder that has repeated episodes of psychosis and is associated with a misunderstanding of the surrounding reality. This condition is associated with a disorder in the cognitive ability of the brain. 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. Our aim in this study is to compare the performance of patients with schizophrenia and healthy individuals in a cognitive-behavioral task of Foraging. Methods: Based on the criteria, patients with schizophrenia 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 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 schizophrenia.
