Resumo: | The attentional bias is the allocation of attentional resources to irrelevant stimuli during a task. It is assumed that patients with obsessive-compulsive disorder (OCD) presents attentional bias toward threatening stimuli. In order to describe OCD’s neurobiological findings of attentional bias towards a threat, it was performed a systematic review of experimental studies with neurobiological assessment in the following databases: MEDLINE, Web of Science, Scopus and LILACS. Four studies with control group are described in this review, all presenting statistically significant differences in brain activity associated with attention in patients. The neurobiological findings of the studies included in the review suggest allocation of attentional resources to irrelevant stimuli, regardless of the emotional valence in OCD. |

Supõe-se que pacientes com transtorno obsessivo-compulsivo (TOC) apresentem viés atencional voltado à ameaça. Com o objetivo de descrever os achados neurobiológicos do viés atencional voltado à ameaça no TOC, foi realizada uma busca sistemática por estudos experimentais com investigação neurobiológica nas bases de dados: MEDLINE, Web of Science, Scopus e LILACS. Quatro estudos com grupo controle são descritos nos resultados, todos indicam diferenças estatisticamente significativas na atividade encefálica associada a atenção em pacientes. Os achados neurobiológicos dos estudos incluídos na revisão sugerem a alocação de recursos da atenção a estímulos irrelevantes, independente da valência emocional no TOC.Instituto de Psicologia - Universidade de Brasília2021-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.unb.br/index.php/revistaptp/article/view/2282510.1590/0102.3772e37212 Psicologia: Teoria e Pesquisa; Vol. 37 (2021)Psicologia: Teoria e Pesquisa; Vol. 37 (2021)Psicologia: Teoria e Pesquisa; Vol. 37 (2021)Psicologia: Teoria e Pesquisa; v. 37 (2021)1806-34460102-3772reponame:Psicologia (Universidade de Brasília.
