Neurobehaviorally Inspired ACT-R Model of Sleep Deprivation: Decreased Performance in Psychomotor Vigilance

Abstract

This report describes how changes in architectural parameters in the Adaptive Control of Thought - Rational (ACT-R) can be used to understand and predict the effects of sleep deprivation on a fundamental aspect of human performance. In a sample task, the parameter manipulations produce changes in the model's performance that closely resemble the neurobehavioral effects seen in human data. The parameter that is manipulated influences a mechanism in ACT-R that is considered to be associated with the thalamus, an area that is sensitive to sleep deprivation.
