Document Summary
One of the first approaches based on the premise that psychological characteristics are due to an underlying physiological system. Elliot had a brain tumor that required the removal of part of his prefrontal cortex. All of his cognitive functions remained normal, but his personality changed. Lost his job, all his money, got a divorce. Reported that he couldn"t feel any strong emotion. One of the most common changes in personality following brain injury is a diminished ability to inhibit or control one"s impulses likely due to disruptions between the frontal lobes, which serve as the executive control center of the brain. Galen taught that the amounts of 4 fluids in the body determined personality: An advantage of the physiological approach is that physiological characteristics can be measured mechanically and reliably. The term physiological characteristics refers to the functioning of organ systems within the body. Examples of physiological systems are the nervous system, the cardiac system, and the musculoskeletal system.
