Document Summary
How physical and neurological processes play into behavior. Psychophysiological assessment: measure of underlying neurological and physiological processes. Brain activity examines structures and areas linked to personality. Bodily responses examines responses of autonomic nervous system linked to personality. Biochemical nts and hormones linked to personality. Electroencephalograph (eeg): surface electrodes used to measure brain activity below the skull. Positron emission tomography (pet): measures cell metabolism in the brain as a response to some stimulation (mental or physical) uses radio isotopes. Functional magnetic resonance imaging (fmri): measures blood oxygen flow to the brain in response to some stimuli. Electromyography (emg): surface electrodes to measure electrical activity in muscles as they respond to stimulus. Electrodermal activity (eda): use surface electrodes to measure electrical activity linked to moisture on the skin in response to a stimulus. Pupillography: measure changes in the size of the pupil in response to stimulus.
