Exploring Multitasking Performance and Fatigue with the MAT-B II: A Narrative Review

Abstract: Multitasking and switching between tasks is a universal function in many occupations as juggling tasks simultaneously can increase task productivity especially with, factors such as workload that can lead to decrements and impair human performance. Fatigue can refer to the effects or after-effects of exerting mental and or physical effort on a task. Fatigue inducing factors such as high workload and time-on-task can impact task management, optimization and prioritization which can lead to performance decrements. Despite the universality of multitasking, from aviation to driving a car whilst talking simultaneously, it is unclear as to what underlying cognitive processes are affected by induced fatigue. This brief narrative review explores the dynamics of cognitive processes with induced fatigue on individual operator and task contexts. With an interest in cognitive-behavioral models and the Multi-Attribute Task Battery II (MAT-B II), this review aims to provide a conceptual background of the MAT-B II and its diverse use in modelling multitasking environments. By describing and investigating fatigue with multidisciplinary expertise, the development and implementation of countermeasures can enhance performance to mitigate the deleterious effects of workload and time-on-task.
