Uncovering the relationship between defence and orienting in emotion: cardiac reactivity to unpleasant pictures.

Abstract

This research was aimed at studying the relationship between the cardiovascular reactivity to an intense auditory stimulus and the subsequent cardiac response evoked by affective visual stimuli in fifty-five subjects who underwent a cardiac reactivity task (presentation of an intense acoustic stimulus), followed by a picture viewing task (54 pictures selected from the International Affective Picture System). Heart rate (HR), electrodermal activity and corrugator supercilii electromyographic activity were recorded. Subjects were divided into two groups - high accelerators and low accelerators - on the basis of the first heart rate acceleration obtained in the cardiac reactivity task. Pictures evoked different cardiac response patterns in each subject group. Unpleasant pictures promoted a lower initial HR deceleration and a higher final acceleration in high accelerators than in low accelerators. This pattern of response was more marked with body damage pictures. Moreover, a relationship was found between the first acceleration promoted by the acoustic stimulus and the HR response waveform to the body damage pictures. These results show that, in an unselected sample of subjects, a subgroup tended to respond to loud stimuli with higher HR acceleration and sympathetic activation and to respond defensively to unpleasant pictures (as found by less initial HR deceleration and higher final HR acceleration), rather than manifesting an orienting response. The elicitation of the defence response by a brain fear system, in which the amygdala is a key structure, is also discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
