title: [Arousal versus threat when inducing an anxiety reaction].
abstract: Over the past years, several authors have used voluntary hyperventilation as a method for inducing physiological arousal and the experience of anxiety. The purpose of this investigation is to analyze the relationship between the process of arousal and the experience of anxiety. In order to induce anxiety, two tasks were assigned: hyperventilating and preparing a speech. General hypothesis tested: hyperventilation will induce a high level of physiological arousal (heart rate and skin conductance) with a limited experience of anxiety (subjective appraisal of valence, intensity, and control), whereas preparing a speech will generate a high level of arousal and a significant increase in the experience of anxiety. A sample of 89 women was divided into two groups (n=45 and n=44). After matching the two groups in various anxiety parameters, both tasks were carried out in a different order by each group in the laboratory. Results obtained confirm the main hypothesis and provide evidence against the use of hyperventilation as a technique for generating anxious experience.
