Describe a psychological situation where a sympathetic and parasympathetic autonomic nervous system response naturally occurs, and how an individual might control these processes.
For example, the sympathetic nervous system tends to cause an acceleration of the heartbeat, whereas the parasympathetic nervous system causes the heartbeat to slow down.
Identify other situations where the body may have the same type of responses. Explain.
How might these physiological changes affect people, and in what ways?
