If an anomalous effect is moderated by the degree of paranormal belief, participants with a stronger belief Were expected to show increased electrodermal response
amplitudes, a stronger increase in heart rate, and a higher hit rate for targets compared with nontargets.
This study also brings up questions regarding the significance of an electrodermal response
to low-level chemical substances.
Earlier studies have shown that mental arithmetic procedures can increase activity in muscle tension, skin temperature, heart rate, electrodermal response
, and systolic blood pressure (e.
In this case, we expected a typical pattern of response differences: higher electrodermal response
amplitudes, suppressed respiration, lower heart rate, and lower pulse activity for probes than for irrelevant objects.
For an electrodermal response
to a sensory stimulus, a rapid increase shortly (1-5 s) after the stimulus onset would typically be expected, followed by a slower decrease (Cacioppo & Tassinary, 1990).
Since Beloff's initial review, additional promising results have emerged from a series of studies which examined the autonomic detection of staring using the electrodermal response
(for reviews, see Braud, Sharer, & Andrews, 1993a; 1993b).
Gruzelier JH, Nicolaou T Connolly JF Peatfield RC, Davies PT Clifford-Rose F Laterality of pain in migraine distinguished by interictal rates of habituation of electrodermal responses
to visual and auditory stimuli.
Furthermore, the algorithm measured two features from startle response (magnitude, rise time) that could be derived from the 'onset' and the 'peak' of electrodermal responses
All children had their electrodermal responses
(EDR), their respiratory sinus arrhythmia (RSA), and their cardiac pre-ejection period (PEP) measured during three successive experimental conditions: a 5-minute baseline, a monetary incentive task, and negative mood induction via an emotionally evocative film clip.
