Abstract des Autors

The present study attempted to analyze the nature of multidimensional anxiety responses (cognitive, somatic, and physiological) and their differential effects upon cue-utilization processing in a dual-motor task situation. Under experimental manipulated evaluative stress, 80 subjects repeatedly performed a visual-tracking task which required them to focus on a continuously rotating target in the subject's central visual field, while, at the same time, completing a reaction time task which required them to perceive and respond to intermittently stimulating visual signals in the subject's peripheral-visual field. The subject's cognitive, somatic, and physiological anxiety responses were assessed prior to dual-motor task performance. The results showed that the cognitive component of anxiety response represents the most influential variable relating to reduced peripheral cue-utilization or attentional processes. Somatic or physiological anxiety has little influence on the attentional processes on a motor-task performance. Furthermore, this study tended to support the concept of multidimensional anxiety states with regard to their differential response patterns in a stressful dual-motor task situation. Verf.-Referat
