Interaction Effects of Physical and Mental Tasks on Auditory Attentional Resources

چکیده
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 to examine the influence of mental and physical workload interactions on auditory attentional resources and performance on verbal and spatial tasks. The moderate level of physical lifting improved the performance of auditory tasks under mental underlaod level. Surprisingly, rSO2 oxygenation changes were sensitive to changes in mental workload; also they were not sensitive to physical workload. The NIRS technique was valuable and sensitive in terms of reflecting the impact of mental and physical workloads on attentional resources and mental activities.

Effect of Physical and Mental Workload Interactions on Human Attentional Resources and Performance
Many tasks in the real world require simultaneous processing of mental information alongside physical activity. Most of researchers have studied the impact of physical activities on simple cognitive tasks, but have neglected other important influences (such as different attentional resource pools, as well as gender). Therefore, this thesis proposes a new model that investigates the combined imp...
متن کاملAuditory Stimulus Detection Partially Depends on Visuospatial Attentional Resources
Humans' ability to detect relevant sensory information while being engaged in a demanding task is crucial in daily life. Yet, limited attentional resources restrict information processing. To date, it is still debated whether there are distinct pools of attentional resources for each sensory modality and to what extent the process of multisensory integration is dependent on attentional resource...
متن کاملCortical responses to changes in acoustic regularity are differentially modulated by attentional load
This study investigates how acoustic change-events are represented in a listener's brain when attention is strongly focused elsewhere. Using magneto-encephalography (MEG) we examine whether cortical responses to different kinds of changes in stimulus statistics are similarly influenced by attentional load, and whether the processing of such acoustic changes in auditory cortex depends on modalit...
متن کاملAudition and vision share spatial attentional resources, yet attentional load does not disrupt audiovisual integration
Humans continuously receive and integrate information from several sensory modalities. However, attentional resources limit the amount of information that can be processed. It is not yet clear how attentional resources and multisensory processing are interrelated. Specifically, the following questions arise: (1) Are there distinct spatial attentional resources for each sensory modality? and (2)...
متن کاملNeuronal effects of auditory distraction on visual attention.
Selective attention in the presence of distraction is a key aspect of healthy cognition. The underlying neurobiological processes, have not, however, been functionally well characterized. In the present study, we used functional magnetic resonance imaging to determine how ecologically relevant distracting noise affects cortical activity in 27 healthy adults during two versions of the visual Sus...
