TLDR
This study evaluated the effects of rise-decay time and intensity of pure tones on cephalic and finger vascular responses and obtained responses similar to those reported by Sokolov, which were interpreted as attributable to startle.Abstract:
This study evaluated the effects of rise-decay time and intensity (70dB; 90dB| of pure tones on cephalic and finger vascular responses. Cephalic dilation responses similar to those reported by Sokolov were obtained, as well as cephalic dilation response*, which were interpreted as attributable to startle. Cephalic constriction responses were observed at 90dB only and occurred more frequently for slow rise than for fast rise tunes which were conducive to the production of startle. The negative results with respect to (he cephalic vasomotor response, reported by most American investigators, can be rationalized from the results of the present study.read more

Effects of Stimulus Intensity on Autonomic Responding: The Problem of Differentiating Orienting and Defense Reflexes
TL;DR: It is concluded that the sole use of autonomic measures to index information processing is inadequate and future research requires both autonomic indices and behavioral and subjective measures of affective and information processing.

Effects of stimulus intensity on cardiovascular activity.
Graham Turpin,David A. T. Siddle +1 more
TL;DR: In this article, the effects of stimulus intensity and repetition on cardiovascular activity were investigated, and it was predicted that as intensity increased, the pattern of physiological activity would change, indicating a transition from the orienting to the defense reflex.

Individual differences in the cardiac response to high intensity auditory stimulation
Frank Eves,John Gruzelier +1 more
TL;DR: A recently reported long latency cardiac acceleration to the initial presentation of a high intensity white noise stimulus was investigated further with pure tones, and marked individual differences in the secondary response were uncovered.

Orienting and humor responses: A synthesis
Lambert Deckers,Debra Hricik +1 more
TL;DR: In this paper, a series of paremeters that affect orienting and humor responses identically were found to be present in the two responses, including the effects of habituation and the degree of stimulus change.

Orienting and Defensive Responses to Visual Stimuli
TL;DR: The responses give by Group NP to the spider slides could be considered to be indicative of an orienting response (OR), while those given by Group SP were consistent with recent conceptions of the defensive response (DR).

The startle and orienting reactions in man. A study of their characteristics and habituation.
TL;DR: The results obtained would favor the hypothesis that habituation of the motor responses may be the manifestation of a decrementing process occurring principally in the lower nervous centers, including spinal neurons, implicated in the observed responses.

Effects of depth and rate of breathing on heart rate and heart rate variability
TL;DR: Effects of depth and rate of breathing on heart rate (HR) and HR variability were observed in two experiments and implications for experiments utilizing HR as a dependent variable and studies of autonomic control were discussed.
