dc.description.abstractLa regulación de la emoción es definida como la capacidad de moldear la reacción ante eventos significativos. La distracción es una estrategia de regulación perteneciente a la familia de despliegue atencional que actúa de manera temprana en la modulación de la emoción y consiste en desviar los recursos perceptuales a elementos que presentan baja prominencia. Por otro lado, se ha propuesto que la dificultad en la regulación de la emoción subyace a diferentes trastornos del estado de ánimo y se han descrito diferencias entre hombres y mujeres respecto a la prevalencia de estas condiciones. El presente estudio implementó la técnica de potenciales relacionados a eventos para identificar diferencias por sexo en la amplitud Late Positive Potential (LPP por sus siglas en inglés) producido por la presentación de estímulos aversivos a los que se les introdujo un distractor. Adicionalmente, se analizó este mismo indicador en una etapa de re-exposición en la cual las mismas imágenes fueron proyectadas, pero sin el elemento distractor. Los resultados demostraron que la implementación de la distracción durante la visualización de las imágenes aversivas produjo disminuciones en la amplitud del LPP en los participantes de ambos sexos desde etapas tempranas del componente al compararlo con las amplitudes producidas por estímulos aversivos sin el elemento distractor. En la fase de re-exposición, las imágenes presentadas previamente con la distracción produjeron mayores amplitudes que aquellas anteriormente presentadas sin distracción en ambos sexos. Los resultados destacan la efectividad de la distracción como estrategia para modular a la baja la respuesta emocional durante la presentación de estímulos aversivos mostrando efectividad similar en los hombres y las mujeres.

dc.description.abstractEmotion regulation is the capacity to shape the reaction to significant events. Distraction is a regulation strategy belonging to the family of attentional deployment that acts early in the modulation and consists of diverting perceptual resources to elements that present low salience. On the other hand, it has been proposed that difficulty in emotion regulation underlies different mood disorders and differences have been described between men and women regarding the prevalence of these conditions. The present study implemented the event-related potentials technique to identify sex differences in the amplitude of the Late Positive Potential produced by the presentation of aversive stimuli to which a distractor was introduced. Additionally, this same indicator was analyzed in a re-exposure stage in which the same images were projected, but without the distractor element. The results showed that the implementation of the distraction during the visualization of the aversive images produced decreases in the amplitude of the LPP in participants of both sexes from early stages of the component when compared to the amplitudes produced by aversive stimuli without the distractor element. In the re-exposure phase, images previously presented with the distraction produced greater amplitudes than those previously presented without distraction in both sexes. The results highlight the effectiveness of distraction as a strategy to down-modulate emotional responding during the presentation of aversive stimuli showing similar effectiveness in males and females.eng
