Document Summary

Lazarus: stress and emotion: demand > resources: stress (threat, resources > demand: challenge (challenged, but not threatened, two factors: demand of the situation and the resources available towards the situation. The two physiological stress systems: sympathetic nervous system (sns, hypothalamus-pituitary adrenal axis (hpa) Theories about the activation of these systems: blascovich & mendes: biophysical model, dickerson & kemeney: social self-preservation system, james p herman: anticipatory vs. reactive. Social self-preservation model of stress: psychological stress involves a social threat, fear involves a physical threat, social threat: hpa, physical threat: sns. Types of stressors: james p herman"s work: limbic system of stress; differentiated two types of stress, reactive: pain, homeostatic signals, inflammation - induce stress that is already there, anticipatory: predators, unfamiliar environments, social challenges, classically conditioned stimuli. Scientific evidence for the models: more studies tend to support social self-preservation model and anticipatory/reactive over the bio- physical model of stress, however, evidence so far is inconclusive.
