Many tasks in the real world require simultaneous processing of mental information alongside physical activity. Whilst physical workload may have an impact on mental performance and attentional resources, most previous studies in ergonomics have not systematically investigated the impact of interactions between physical and mental demand on individual performance. The purpose of this study was ...

Attentional cost of the executive functions involved in postural control. The present paper tried to provide a review of the different works investigating the attentional cost of postural control. Within the context of a dual-task, the attentional demand associated with postural control depends on various factors such as (1) the automatic or voluntary focalisation of attention on postural contr...

This paper reports an experimental investigation of attentional engagement to and disengagement from pain. Thirty-seven pain-free volunteers performed a cueing task in which they were instructed to respond to visual target stimuli, i.e. the words 'pain' and 'tone'. Targets were preceded by pain stimuli or tone stimuli as cues. Participants were characterized as high or low pain catastrophizers,...

Cholinergic neurotransmission has been shown to play an important role in modulating attentional processing of visual stimuli. However, it is not yet clear whether the neurochemical acetylcholine (ACh) is necessary exclusively for visual attention, or if it also contributes to attentional functions through some modality-independent (supramodal) mechanism. To answer this question, we examined th...

Cognition is organized in a structured series of attentional episodes, allowing complex problems to be addressed through solution of simpler subproblems. A "multiple-demand" (MD) system of frontal and parietal cortex is active in many different kinds of tasks, and using data from neuroimaging, electrophysiology, neuropsychology, and cognitive studies of intelligence, I propose a core role for M...

Objective The aim of this review is to identify how visual occlusion contributes our understanding attentional demand and spare capacity in driving the strengths limitations method. Background technique was developed by John W. Senders evaluate driving. Despite its utility, it has been used infrequently driver attention/inattention research. Method Visual studies published between 1967 2020 wer...

Postural control is important to cope with demands of everyday life. It has been shown that both attentional demand (i.e., cognitive processing) and fatigue affect postural control in young adults. However, their combined effect is still unresolved. Therefore, we investigated the effects of fatigue on single- (ST) and dual-task (DT) postural control. Twenty young subjects (age: 23.7 ± 2.7) perf...

[Purpose] The purpose of this study was to determine the change of allocation of attention caused by a difference in gait phase and gait speed. We also determined the relationship between attentional demand and gait automaticity change caused by the gait speed alteration. [Subjects and Methods] Ten male participated. Participants were instructed to perform the probe reaction time (RT) task duri...
