Low-Arousal Speech Noise Improves Performance in N-Back Task: An ERP Study
The relationship between noise and human performance is a crucial topic in ergonomic research. However, the brain dynamics of the emotional arousal effects of background noises are still unclear. The current study employed meaningless speech noises in the n-back working memory task to explore the changes of event-related potentials (ERPs) elicited by the noises with low arousal level vs. high a...
متن کاملThe spatial-verbal difference in the n-back task: an ERP study.
The spatial-verbal dichotomy of working memory tasks was investigated using event-related potentials. Using an n-back task with three levels of n (0-, 1-, and 2-back), participants either matched words presented at a fixed screen position (verbal task) or matched the locations of non-word symbols presented at various positions across the screen (spatial task). Therefore, these two conditions we...
متن کاملDistracting the Mind Improves Performance: An ERP Study
BACKGROUND When a second target (T2) is presented in close succession of a first target (T1), people often fail to identify T2, a phenomenon known as the attentional blink (AB). However, the AB can be reduced substantially when participants are distracted during the task, for instance by a concurrent task, without a cost for T1 performance. The goal of the current study was to investigate the e...
متن کاملMuscle strength, task performance and low back load in nurses.
Poor muscle strength, relative to the physical demands of specific jobs, is considered a risk factor for low back pain. To gain an understanding of the underlying mechanisms, this study questioned whether muscle strength was related to task performance and low back load in nursing tasks. Trunk extension, elbow flexion and knee extension strength were therefore measured in 17 nurses. The indepen...
متن کاملInterference from the irrelevant domain in n-back tasks: an ERP study.
Selective attention and interference from the irrelevant domain are frequently neglected factors in working memory experiments. Here identical stimuli were employed in n-back tasks under spatial and verbal task instructions to test whether information in the irrelevant domain was really irrelevant. The results reveal interference from the irrelevant domain in the replacement sub-process of the ...
