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.
