What is anxiety? - anxiety is an unpleasant emotional state ranging from mild unease to intense fear - a certain amount of anxiety, however, is normal and serves to improve performance - anxiety rouses you to action. It gears you up to face a threatening situation. It makes you study harder for that exam, and keeps you on your toes when you’re making a speech. In general, it helps you cope. Psychophysiological/ Physic Component - objective measurements that can indicate a person is anxious: heart rate, respiration, pupil dilation Psychological Component - Characterized by irritability, lack of concentration, feelings of fear (cognitive) o Feelings of fear make me feel anxious—more subjective o Psychological measurement, although subjective, is the most commonly used in psychopathology: rating of anxiety. Interpersonal Component/ Observable Component - all basic emotions come with observable change - measurable component for anxiety Anxiety is generated when we perceive to be threatened (be it real or unreal) Physiological response to fear and anxiety would be similar but the difference is the circumstance. - Fear is the reaction of an immediate threat; anxiety is a reaction to a perceived threat. The perception of threatening stimuli is registered in the frontal lobes of the brain, after limbic system processing. Generation of fear and anxiety is in the amygdala. - lesion in amygdala in animals show no fear –tamed - fMRI shows activation of limbic and basal ganglionic structures in a patient suffering a panic attack. - Motivation is generated by hypothalamus The brain alters the body’s physiology by activating the autonomic nervous system - sympathetic division creates the anxiety reactions by activating the Visceral effectors; parasympathetic division has the opposite reaction.
