Document Summary

Modern physiological researchers: focus on distinct physiological systems (cardiovascular activity, electrodermal activity, brain electrical activity, immune system indicators, cortisol, etc. , examining whether physiological differences are related to personality differences. Most obtained by electrodes or sensors placed on the skin surface. Eda due to increased sweat with arousal, skin conductance of electricity increases. Eda in the absence of external stimuli associated with anxiety and neuroticism. Heart rate increases with anxiety, fear, arousal, cognitive effort. Cardiac reactivity when performing task such as backward serial subtraction: associated with type a personality impatience, competitiveness, hostility, cardiac reactivity (and type a) associated with coronary heart disease. Student stress study carleton u. , 2000-2001: dr. hymie anisman stress and pathology lab. Different levels of stress based on cortisol levels: dr. kim matheson social diversity lab. Coping centre for stress, coping and well-being: cotton balls, saliva samples, and stress. Brain imaging techniques map structure and function of brain: positron emission tomography (pet, functional magnetic resonance imaging (fmri)
