Document Summary

Psyc06 - lecture 2, chapters 4 & 5 methods of psychophysiology. Arousal heightened activation of the autonomic nervous system in response to a stimulus. The arousal will be specific to each physiological measure in the ans. Arousal will be specific to each stimulus that elicits it. Stimulus-response specificity the way each peripheral physiological response will become aroused depends on specific features of the stimulus to which it is reacting. Habituation decreased activation as a stimulus becomes less novel. Baseline tonic activity: the activity of a participant while they are at rest, with no evocative stimulus. Nothing is more important in physio than a good baseline. Law of initial values the degree to which a physiological response will change is a function of its starting level of activation. Specifically, greater phasic change is exhibited among lower tonic levels. This law" is not universal, but it is predominantly true.
