The ________ theory indicates that some stress stimulates
the body into action, and people are able to perform well. However, too much stress causes a person to perform poorly.
The logic underlying the inverted U is that low to moderate levels of stress stimulate the body and increase its ability to react. Individuals then often perform their tasks better, more intensely, or more rapidly. But too much stress places unattainable demands on a person, which result in lower performance.
