Abstract(s)
Problema: O reconhecimento de faces é uma competência cognitiva fundamental, única e
essencial para desenvolvimento e comportamento socio-afetivo. No contexto da testemunha
ocular, o reconhecimento de faces é importante e integra diversos processos, sendo que entre
as abordagens que permitem extrair dados e detalhes da testemunha sobre a face do suspeito,
os lineups constituem-se como os melhores processos de identificação. No entanto, a literatura
em Portugal é escassa sobre a relação entre o reconhecimento de faces e o processo de
identificação lineup. Objetivo: Estudar a associação da memória de reconhecimento facial com
uma tarefa similar ao método lineup e analisar o contributo de outras variáveis nesta relação.
Método: Foi aplicado a 50 participantes a tarefa de identificação de suspeitos, similar aos
lineups, e a prova Cambridge Face Memory Test (CFMT), que avalia o reconhecimento de
faces, através de 3 fases: fase de introdução de faces, a fase introdução de novas faces e a fase
introdução de novas faces com ruído. Resultados: Nas diversas análises realizadas é constatado
que existem apenas associações significativas entre o sexo e a tarefa de Introdução de novas
faces do CFMT. Discussão: Estes resultados não corroboram com a hipótese em estudo, no
entanto, existem várias ressalvas quanto às conclusões obtidas, tendo por base as limitações da
amostra, como a sua dimensão ou faixa etária, mas também erros na formação da tarefa de
identificação de suspeitos.
Problem: Face recognition is a fundamental cognitive competence, unique and essential forsocio-affective development and behavior. In the context of the eyewitness, face recognition is important and integrates several processes, and among the approaches that allow extracting data and details of the witness about the face of the suspect, the lineups are one of the best identification processes. However, the literature in Portugal is scarce about the relationship between face recognition and the lineup identification process. Objective: To study the association of facial recognition memory with a task like the lineup method, such as analyzing the contribution of other variables in this relationship. Method: The task of identifying suspects, like lineups, and the CFMT test, which evaluates face recognition, through 3 phases: phase of introduction of faces, phase of introduction of new faces and phase of introduction of new faces with noise, were applied to 50 participants. Results: In the various analyses performed, it is found that there are only significant associations between sex and the task introduction of new faces of CFMT. Discussion: These results do not corroborate the hypothesis under study, however, there are several caveats regarding the conclusions obtained, based on the limitations of the sample, such as their size or age group, but also errors in the formation of the task of identifying suspects.
