Document Summary
Stress is located at the extreme end of a continuum of arousal. Every behavior is the result of activity on our ns. Motivation=emotion=arousal * -- both motivation and emotion result from changes in arousal. Emphasize the organism as a whole, we can understand behavior best if we understand how the organism becomes activated. We can understand motivation by viewing it on a continuum of behavioral action. Assumes that behavior will change as we become more aroused.

Relationship holds for some types of tasks but not for others. What is optimal for one task may not be optimal for another; more complex and task- specific then we think.
