The psychophysiology of skeletal muscle tension patterns during goal-directed behavior was investigated by using the continuous perceptual-motor task paradigm. Subjects were recruited to form serious-minded and playful extreme groups according to their responses to the Telic Dominance Scale (10 subjects in each group). They all performed a continuous perceptual-motor task 5 times at a 'slow' speed followed by a final 'fast' task. All performance periods lasted for 150 s. Measures of passive (tonic) and active (phasic) forearm flexor EMG activity were derived. It was concluded that serious-mindedness was significant to a tonic build-up of tension in the passive forearm flexor over the course of task performance. In contrast, the playful state was associated with high phasic response amplitudes in the active forearm flexor contingent upon changing the position of the joy-stick. Training moderated the range of state-specific EMG activation. State measures confirmed that the subjects maintained their state dominance during task performance. Error-scores and scores on felt level of arousal did not discriminate between the groups.
通过使用连续感知运动任务范式，对目标导向行为期间骨骼肌紧张模式的心理生理学进行了研究。根据受试者对目的主导力量表的回答，招募他们组成严肃和好玩的极端组（每组10名受试者）。他们都以“慢”速度进行了5次连续感知运动任务，随后进行最后一次“快”任务。所有表现期持续150秒。得出了被动（紧张性）和主动（相位性）前臂屈肌肌电图活动的测量值。得出的结论是，在任务执行过程中，严肃性对于被动前臂屈肌中紧张的紧张性积累具有重要意义。相比之下，好玩的状态与主动前臂屈肌中因操纵杆位置变化而产生的高相位反应幅度相关。训练调节了特定状态肌电图激活的范围。状态测量证实，受试者在任务执行期间保持了他们的状态优势。错误分数和感觉唤醒水平分数在两组之间没有差异。
