ABSTRACT
O presente trabalho apresenta uma revisão bibliográfica feita na base de dados Web of Science e Scielo, onde foram encontrados 266 artigos que tratam diretamente sobre estimulação aversiva e cognição no período de 1968 a 2010. Posteriormente, foram utilizados 64 artigos para esta revisão. Fez-se então uma citação das principais categorias e métodos de trabalho, assim como tópicos que direcionam as pesquisas atuais e principais avanços sobre o tema. Considerando os trabalhos encontrados, embora haja um grande avanço, principalmente, nas últimas duas décadas, sobre o assunto, ainda é um campo que necessita de muito estudo, para avaliar a interferência da estimulação aversiva sobre a cognição...
This work presents a bibliographical review of material from Web of Science and Scielo database. 266 publications were found that link directly aversive stimulation and cognition from 1968 to 2010. Based on further analysis, 64 studies were used for this review. It was made a citation of the main categories and methods then, as well as topics that address the current researches and main progresses on the theme. Considering the selected papers, although there is considerable progress, mainly, in the last two decades on this topic, it is still a field that needs a lot of study in order to evaluate the interference of cognition by aversive stimulation...

The present study investigated the influence of aversive visual stimulation on anxiety, working memory, and selective attention. The study was conducted with 366 participants of both sexes, divided into three groups: (i) no visual stimuli (n = 128), (ii) neutral visual stimuli (n = 114), and (iii) aversive visual stimuli (n = 124). Two DVD films, one containing aversive stimuli and one containing neutral stimuli, were used for the respective groups. Each visual stimulation had a duration of 1 minute and 22 seconds. After viewing the DVD, anxiety, working memory, and attention were assessed. Concomitant with the increase in anxiety were deficits in working memory and deficits in selective attention in the group that was exposed to the aversive scenes. No gender differences were observed. These results suggest that aversive visual stimuli increase anxiety and decrease attention and working memory performance in university students.
