What specific equipment is needed for psychophysiological measurement? If I understand the research so far I will need equipment that measures both cardio and vascular responses..that is impedance cardiographic and blood pressure recording devices....I can hardly write it down never mind understand what it is!!! I am hoping (operative word) to evoke challenge and threat patterns of cardiovascular response by experimental manipulation...
If any of this makes sense...could anyone out there enlighten?
