Document Summary
Performer: the natural arousal level for one individual may be significantly higher than. Task: as a task increases in complexity, lower levels of arousal are optimal that of another. Trait anxiety: an individual"s propensity to perceive situations as threatening or nonthreatening. Changes in attentional focus occur according to arousal levels (i. e. , attention is broad if arousal is low) Attentional focus narrows towards task-relevant cues as arousal approaches optimal levels: Range of arousal levels causing optimal performance. Narrowing of attentional focus with increases arousal levels. Process of organizing a system"s available degrees of freedom into a efficient movement pattern to achieve a specific goal. If the task is smooth then the person is probably coordinated but if the person is awkward then the person is not coordinated. Manipulating variables within a movement to meet demands of a given situation. How we coordinate and control the available degrees of freedom to produce a movement is the degrees of freedom problem.
