O presente estudo tem como principal objetivo compreender se existe alteração do diâmetro pupilar na identificação de falsas memórias. Deste modo, definiu-se como variável independente a falsa memória e como variável dependente a variação do diâmetro pupilar. Delimitou-se um estudo com design quasi-experimental, incidindo no paradigma Deese-Roediger-McDermott (DRM) (1995), no qual foram utilizadas seis listas compostas por oito palavras cada, sendo que a cada uma está associada uma palavra crítica. Neste estudo participaram, voluntariamente, 45 estudantes da Universidade da Beira Interior, tendo sido definidos critérios de exclusão relacionados com problemas visuais. Estes participantes realizaram uma experiência de memória com a duração de quinze minutos e dividia em três fases: a fase de estudo, a fase de realização de uma tarefa distractora e a fase de reconhecimento. Nesta última fase, era medido o diâmetro pupilar com recurso a eye tracking. Da análise dos resultados pode verificar-se a manifestação do paradigma DRM, bem como o aumento do diâmetro pupilar na presença de falsas memórias. Quando analisados os diâmetros pupilares perante os diversos estímulos apresentados, verificou-se que não existem diferenças entre o género masculino e feminino.
This study aims to understand if there is change in pupil diameter in the identification of false memories. Thus, it was established as an independent variable, the false memory and dependent variable was the change in pupil diameter. The present study has a quasi-experimental design, focusing on the Deese-Roediger-McDermott paradigm (1995), using six lists, each composed of eight words, each of which is associated with a critical word. Participated in this study, voluntarily, 45 students from the University of Beira Interior, and it were defined as exclusion criteria, people who had vision problems. These participants performed a memory experiment with duration of fifteen minutes and divided into three phases: the study phase, the implementation phase of a distractor task and the recognition phase. In this last phase, the pupil diameter was measured using eye tracking. Through the analysis of the results we can observe the manifestation of the DRM paradigm as well as the increase in pupil diameter in the presence of false memories. When analyzing pupil diameters before the various stimuli, it was found that there are no differences between males and females.
