Document Summary
Two classic and basic theories: drive theory, inverted u-theory. Basic tenets: higher arousal elicits dominant response, simple or automaic tasks = no skill requirement, dominant response is correct response (reacion ime test) Complex tasks: early in learning the dominant response is incorrect response, late in learning the dominant response is the correct response (choice rxn ime test, higher arousal might not be good unil you get good at the task. As arousal goes up you should be geing beter at the task (if you"re good at task), those who aren"t good at task as arousal goes up, performance goes down. Motor issues: muscle tension, acivaion and motor coordinaion. When arousal goes up there"s a psychophysiological change, sns more acivated. Based on classic research of yerkes and dodson. Best performance (signal detecion and learning) occurs at a moderate level of arousal. Improvements in performance are gradual as arousal increases to a point of opimal arousal/performance.
