Document Summary
Substantive theme : happiness: basically do a survey bout happiness. There has been a long history of electrodermal activity research, most of it dealing with spontaneous fluctuations or reactions to stimuli. Graph of gsr: due to the response of the skin and muscle tissue to external and internal stimuli, the conductance can vary by several microsiemens, when correctly calibrated, the device can measure these subtle differences. There is a relationship between sympathetic activity and emotional arousal, although one cannot identify which specific emotion is being elicited: the scr is ly sensitive to emotions in some ppl. Fear, anger, startle response, orienting response and sexual feelings are all among the reactions which may produce similar skin conductance responses: these reactions are utilized as part of the polygraph or lie detector. Lie detectors are deemed to be not usable u dunno which emotion the person is really feeling if theres a .
