Document Summary
When we look at a variety of body functions, there is also a tremendous amount of information about things that seem to differ between offenders and non-offenders. Place small electrodes on two sites of the hand, then passing very tiny currents across the electrodes, changes in skin conductance activity then be measured. Skin conductance is a very fast response 1-3 seconds after stimulus, so measurement of skin conductance provides a very sensitive measure of allocation of attentional resources. Sc is an ans measure ans is important in emotional behaviour, so sc has been used to measure states such as anxiety, emotional arousal, and stress. Some evidence of under-arousal in antisocial people (esp those who committed crimes of evasion) Psychopaths more responsive to speech like stimuli (perhaps relate to verbal characteristics of psychopaths, lying, deception, superficial charm, conning), less responsive to disturbing pictures. Many studies consistently found a lower resting heart rate in juveniles with antisocial behaviour than in non-antisocial controls.
