In psychology, the Neurobiological or Neuroscience Approach involves understanding the body and brain creates emotions, memories, and sensory experiences. The advantage of using this perspective is the scientific data can be used to support the reality of how humans experience life, proving that psychology is, indeed, a science. For example, when someone gets "red in the face" in anger, if they are linked to an EEG scanner we can verify that their anger is not an imagination or a "subjective" sensation, as the data would show a rise in stress level in the brain. And if they are feeling relaxed, the same scanning can be done to prove their relaxed state of mind, either during meditation or listening to soft music or even track the various stages of sleep they are in. Therefore, treatment for patients with Depression or Bipolar Disorder can be done through the use of medications to control the serotonin or dopamine levels in their brains. And that provides faster relief than months and months of Ohm-ing and Ah-ing in meditation practices.The disadvantage to this perspective is that it does NOT explain psychology thoroughly. Each individual's emotions and thinking processes involve more than "brain waves" or "chemical triggers in the blood," such as the reality of external environmental events that trigger the anger in the first place.
There are several ways to approach psychology. These approaches are theories, since psychology is a science that is based on behavior. Things can't be proven, because there is never any circumstantial evidence, only statistics, studies, and researches to make theories.
The neurobiological approach is simply biological. Neurobiologists believe that actions and reactions caused are from nerve cells. Neurobiologists study the physical features of the human body instead of the mind. They focus on perspiration such as tears, sweat, and physical movement in reaction to something else (i.e., the sudden standing up of hair when in fright).
