Resumo: | Witnessing a crime can be a highly stressful situation, eliciting arousal levels that may affect eyewitness memory performance. In two experiments, participants watched a mock crime with varying arousal intensities (neutral, robbery, and murder), and provided reports after varying retention intervals (immediate testing, 7 days, 14 days or 21 days). Results showed that arousal did not have a significant main effect on eyewitness memory recall. Eyewitness memory performance was stronger for the event with higher arousal only after a 7 days retention interval, but performance was comparable across all arousal conditions in longer retention intervals. Theoretical and practical implications related to the evaluation of eyewitness testimony are discussed. |

Em dois experimentos, participantes assistiram a eventos com diferentes cargas emocionais (neutro, assalto ou assassinato) e forneceram seus relatos após diferentes intervalos de retenção (teste imediato, 7 dias, 14 dias ou 21 dias). Os resultados mostraram que a carga emocional não teve efeito na memória de testemunhas para aspectos do crime e características do criminoso. O evento com maior carga emocional teve um efeito benéfico na memória após um intervalo de 7 dias, mas tal efeito não ocorreu em intervalos mais longos. Implicações teóricas e práticas relacionadas à interpretação do relato de testemunhas são discutidas.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/2975510.1590/0102.3772e37211Psicologia: 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.
