TL;DR
The results suggest cognitive fatigue and communication latency to demand similar cognitive resources and non-fatigued participants to raise system expectations and future research should validate these findings with a larger sample size.
Abstract
Cognitive fatigue is a decline in cognitive efficiency due to sustained mental demands, leading to detrimental effects in safety-critical tasks. To combat individual demands, AI teammates may be integrated to distribute complex task demands across members where cognitive fatigue has been shown to impair team coordination. However, prior literature has not examined how cognitive fatigue manifests within human-AI teams. This work empirically examines the effects of cognitive fatigue and the system constraints of communication latency in human-AI teams during a safety-critical task. A 2*2 within-subjects design was tested with cognitive fatigue (fatigue vs. non-fatigue) and communication latency (250 milliseconds vs. 1250 milliseconds). A two-way repeated measures analysis of variance suggested interaction effects for task efficiency and perceived frustration. The results suggest cognitive fatigue and communication latency to demand similar cognitive resources and non-fatigued participants to raise system expectations. Future research should validate these findings with a larger sample size.
In daily life, people often ignore feelings of fatigue to meet cognitive demands. This ‘fatigue override’ is the ability to maintain performance despite feeling tired. In both clinical and non-clinical samples, we examined whether better performance (i.e., faster processing speed) or high fatigue levels in precedin...

ABSTRACT Background Fatigue in people with multiple sclerosis (PwMS) is common and disabling, yet poorly understood. This study aimed to clarify the distinction between long‐term fatigue and task‐induced fatigability and their respective pathophysiological processes, and to examine the contribution of decreased cogniti...

Hearing aid users commonly report listening-related fatigue, which may contribute to disengagement from demanding listening situations and negative psychosocial outcomes. Hearing rehabilitation currently lacks strategies to mitigate listening fatigue, partly because fatigue build-up and its consequences are difficult t...

Previous research in time perception has predominantly focused on how cognitive and emotional factors influence subjective time perception. However, investigations into whether subjective time perception, in turn, affects emotional and cognitive outcomes remain limited. To address this, the current study systematically...

Cognitive performance in real-world environments often requires maintaining working memory under simultaneous cognitive demand and environmental distraction. Although both factors have independently been associated with alterations in attention and executive control, their combined neural effects remain insufficiently...

Mental fatigue is often invoked to explain performance changes after sustained cognitive engagement, yet the antecedent cognitive-demand protocols used in sport research are heterogeneous and do not invariably elicit an equivalent fatigue state. This narrative review synthesizes 84 publications to clarify the distincti...
