TLDR
Level of arousal was manipulated by having subjects perform arithmetic tasks during a habituation procedure, which consisted of 55 presentations or a 1000 Hz tone, and a threat of shock was added to the task performance in order to include aspects of stress in the arousal manipulation.Abstract:
Level of arousal was manipulated by having subjects perform arithmetic tasks during a habituation procedure, which consisted of 55 presentations or a 1000 Hz 80 dB tone For one group a threat of shock was added to the task performance in order to include aspects of stress in the arousal manipulation These two groups were compared with a group who heard the same stimuli but were simply instructed to relax The three groups differed in level of arousal according to KEG signs of drowsiness, skin conductance level, and frequency of spontaneous skin conductance responses, All three groups differed from each other in number of trials to habituation criterion for skin conductance responses to stimuli Since the delay of habituation was seen tin- both the Task group and the Shock-threat group, it was concluded that the effect was not bound to aspects of stress but was a general effect of increased arousal For vasomotor responses an analysis in terms of habituation was difficult to apply because the two high arousal groups were very unresponsive from the beginningread more

Situational and psychophysiological factors in psychologically induced pain
TL;DR: The results suggest that pain can be produced in the absence of peripheral stimulation, and does not appear to be due to intentional deception or the lack of a standard for comparison, but is strongly influenced by environmental cues.

Emotional modulation of skin conductance and eyeblink responses to a startle probe
TL;DR: Both the eyeblink and skin conductance responses to startle probes were potentiated during fear as compared with neutral and pleasant imagery, and the amount of emotional modulation in these two response systems was significantly correlated both between and within subjects.

The Relationship of Symptomatology and Medication to Electrodermal Activity in Schizophrenia
TL;DR: Both symptomatology and type of neuroleptic are related to electrodermal measures, with the anticholinergic effect of Neuroleptic medication being more pronounced.

Gateways to consciousness : Emotion, attention, and electrodermal activity
TL;DR: The autonomic nervous system provides an important ingredient of emotion as discussed by the authors, and the autonomic activation is necessary but not sufficient for genuine emotion, whereas still others have claimed only that it contributes to emotional experience.

Tonic and phasic co-variation of peripheral arousal indices in infants
TL;DR: High covariation between ANS indices in infants was found and pupil size and EDA showed more complicated patterns, and different patterns were seen between tonic and phasic analyses.

A physiological model of phobic anxiety and desensitization.
Malcolm Lader,A.M. Mathews +1 more
TL;DR: An alternative explanation consistent with the above postulate states that the underlying mechanism of systematic desensitization is identical with that of habituation proceeding under optimal conditions (the “maximal habituation” hypothesis).

The orienting reflex during waking and sleeping
Laverne C. Johnson,A. Lubin +1 more
TL;DR: There was little, if any, habituation of the OR during sleep, and the presence of a stimulus-evoked K complex was associated with increased responsiveness in all autonomic variables, but presence of eye movement bursts wasassociated with decreased cardiovascular response to the tone.

Self-reported arousal: further development of a multi-factorial inventory.
Anders Kjellberg,Gunilla Bohlin +1 more
TL;DR: The previously presented inventory of self-reported arousal, which contained four factor analytically derived scales, was further developed in the following way: the original factor pattern was cross-validated and a new response scale was constructed which proved to be superior to the old one.
