Document Summary

Provides a measure of the sympathetic nervous system activity, measures how much your sweating (sweat conducts electricity) Emotional reactivity: intensity and persistence of emotion in response to stimuli. Thought to be elevated among those who self-injure. Induced stress in 2 groups and measured skin conductance (individuals with a history of self- injury vs. Had a matching game in which failure feedback is given (even when a response is correct) The goal was to determine how long people would stay in the game & tolerate distress from negative (failure) feedback. The self injury group had higher degrees of skin of skin conductance as the minutes went on compared to those without the history. *they also reported more negative emotion, they also quit the game sooner which also might indicate lower distress tolerance. Blood pressure: pressure exerted by blood in the artery walls, common measure of stress response. Heart rate: expressed in bpm (i. e interval between beats).
