PerPsych: An iPadOS-based open-source neuropsychological software for time perception assessment

Abstract

Time perception is an important aspect of cognitive function that can be affected by mental illness and brain disease. Neuropsychological tests often assess time perception using computer displays, but smartphone or tablet software may offer some advantages. In this study, we present PerPsych, an open-source, iPadOS-based neuropsychological tool for testing time perception. PerPsych has the following features: • It is designed natively for iPadOS, using the low-level Metal interface to access the graphics processing unit for high-timing performance. • It allows researchers to conduct studies on time perception in individuals with cognitive impairment using a simple and user-friendly interface. • It supports various experimental paradigms and parameters for measuring time perception, such as duration estimation, production, and reproduction.
