Final answer:
The Triangle Model of Optimal Performance includes three sides: arousal, skill level, and task demands. Arousal refers to the level of activation, skill level refers to the individual's expertise, and task demands refer to the complexity of the task.
Step-by-step explanation:
The Triangle Model of Optimal Performance is a psychological framework that explains the different sides or components involved in achieving optimal performance. It consists of three sides: arousal, skill level, and task demands.
Arousal:
Refers to the level of physiological and psychological activation or energy a person experiences. A moderate level of arousal is usually associated with optimal performance. Too little or too much arousal can negatively affect performance.
Skill Level:
Refers to the individual's level of expertise or proficiency in performing a particular task. Higher skill levels are generally associated with better performance.
Task Demands:
Refers to the complexity or difficulty of the task being performed. The optimal performance occurs when the task demands match or slightly exceed the individual's skill level.
