Antecedentes:
Emotional reactions are crucial in survival because they provide approach and withdrawal behaviors. However, an unsolved question is wether the social content of the affective stimuli has a specific effect on emotional responses.
Métodos:
For this purpose, we recorded startle bink reflex (a defensive response) and skin conductance responses (a measure of unspecific physiological reactivity or arousal) in 73 participants while they viewed a series of 81 pictures of varying affective valence and arousal content.
Resultados:
Our results revealed that defense response, as indicated by increases in the magnitude of the startle blink reflex, was mainly dependent on threatening or unplesant cues, but was unrelated to the social content of the pictures. The social content, however, had an influence on pleasant stimuli, provoking an increase in resource mobilization, as reflected by changes in electrodermal activity.
Conclusiones:
Hence, the social content of the affective stimuli may increase the physiological arousal elicited by pleasant stimuli, and it appears to be unrelated to the defense reactivity provoked by unpleasant stimuli
