Title Psychophysiological changes during a VDU repetitive task
Bibliographic information Oct. 1985, Vol.28, No.10, p.1455-1468. Illus. 36 ref.
Abstract A simulated realistic 120min data-entry task on a visual display terminal was employed to study the relationship between performance and various physiological indices of arousal. For 80% of the subjects, performance showed a progressive decline, reaching minimal values after 45-46min of work, followed by a significant rebound. Behavioural responses were associated with EEG arousal changes whereas average heart rate decreased from beginning to the end. The EEG pattern accompanying the rebound of the performance during the data-entry task supports the auto-arousal hypothesis which assumes that a cerebral compensatory effort intervenes in a mental repetitive task.
