Résumé
Les sujets anxieux présentent souvent des troubles attentionnels avec un biais pour les stimuli à contenu menaçant. L’anxiété, comme toute autre émotion, s’accompagne de réactions physiologiques périphériques plus ou moins manifestes affectant le comportement et l’état de l’organisme. Compte tenu des modifications psychophysiologiques associées à l’anxiété et aux troubles anxieux on s’est intéressé à rechercher des liens entre les mesures psychophysiologiques et les phénomènes de sélectivité attentionnelle. Ce phénomène a effectivement été observé, c’est-à-dire une activation élective de fonctions psychophysiologiques comme réaction à des stimuli menaçants, et une diminution lors de l’exposition aux stimuli neutres.
Abstract
Anxious people often show a particular attentional focus towards potentially threatening stimuli. Like any other emotion, anxiety goes along with physiological reactions, which may be more or less noticeable, and may impair behavior and physical wellness. In view of the psychophysiological reactions related with anxiety and anxiety disorders, it seems important to examine potential correlations between psychophysiological activity and the phenomena of hypervigilance. In fact, selective psychophysiological activation has repeatedly been found as a reaction to pathology-specific threatening stimuli in patients with anxiety disorders, whereas their psychophysiological responses appeared often to be blunted when they were submitted to neutral stimuli.
Resumen
Los pacientes ansiosos presentan con frecuencia trastornos de atención con una inclinación a los estímulos de contenido amenazador. La ansiedad, como cualquier otra emoción, se acompaña de reacciones fisiológicas periféricas, más o menos manifiestas, que afectan el comportamiento y el estado del organismo. Dadas las modificaciones psicofisiológicas asociadas con la ansiedad y los trastornos de ansiedad, nos interesamos en la investigación de las relaciones entre las medidas psicofisiológicas y los fenómenos de selectividad de la atención. Este fenómeno ha sido efectivamente observado, es decir existe una activación electiva de las funciones psicofisiológicas como reacción a los estímulos amenazadores y una disminución en el momento de la exposición a los estímulos neutros.
Resumo
As pessoas ansiosas apresentam freqüentemente transtornos da atenção com uma tendência para os estímulos de conteúdo ameaçador. A ansiedade, como qualquer outra emoção, é acompanhada de reações psicológicas periféricas mais ou menos manifestas que afetam o comportamento e o estado do organismo. Levando em consideração as modificações psicofisiológicas associadas à ansiedade e aos transtornos de ansiedade, ficamos interessados em pesquisar os elos entre as medidas psicofisiológicas e os fenômenos de seletividade da atenção. Este fenômeno foi realmente observado; trata-se de uma ativação eletiva de funções psicofisiológicas em reação a estímulos ameaçadores e uma diminuição durante a exposição a estímulos neutros.
