Document Summary
Motivations either motivate away or towards a stimulus, they do that by producing an emotion. A threat that has no rational reality is a phobia and it is a psychopathology. Psychophysiological (physical) component: racing heart, sweating, etc. Psychological component: characterized by irritability, lack of concentration and feeling of fear. Interpersonal component: featuring an inclination to cling to other people for reassurance. Anxiety is generated when we percieve to be threatened (be it real or unreal). Fear is considered a closely related emotion; it is in response to a direct threat (such as riding a roller coaster). The perception of threatening stimuli is registered in the frontal lobes of the brain, after limbic system processing. Amygdala is extremely important in the production of anxiety. The brain alters the body"s physiology by activating the autonomic nervous system. Anxiety disorders all have a sense of apprehension of a stimulus that is threatening as well as the 3 major components described above ^.
