Abstract(s)
O objectivo assentava na comparação da população deprimida com a não deprimida, bem como na compreensão do papel da familiaridade no Efeito de Verdade nos deprimidos. Indivíduos avaliaram em termos de valor de verdade dois tipos de frase, Normal e Depressiva, repartindo-se em duas condições de frase, Nova e Repetida. Os indivíduos foram ainda divididos em duas categorias distintas – indivíduos Deprimidos e Não Deprimidos – consoante resultados no Inventário da Depressão de Beck. Concluiu-se que o Efeito de Verdade é significativo para toda a população, havendo maior valor de verdade atribuído a frases depressivas, em comparação com as normais. As amostras deprimida e não deprimida foram comparadas e os resultados atingiram significância, mas encontrou-se um valor marginal apontando para uma tendência de maior Efeito de Verdade para a amostra não deprimida, como esperado. A hipótese principal não é corroborada, apesar de existir um padrão, na amostra deprimida, para um maior Efeito de Verdade em frases depressivas, em comparação com as normais. Os resultados são discutidos e apresentam-se propostas de estudos futuros e suas implicações para a compreensão dos processos cognitivos na depressão e para adaptação de terapêuticas à condição.
The goal of the study was to compare the depressed population with the non-depressed, as well as to comprehend the role of familiarity in the Truth Effect on depressed subjects. Individuals evaluated the truth value of two types of sentence, Normal and Depressive, which divide in two conditions, New and Repeated. Individuals were also divided between the Depressed and Non-Depressed category – according to their results in the Beck Depression Inventory. We arrived at the conclusion that the Truth Effect is significant throughout the whole study population, and that there is more truth value given to depressed sentences, comparing to normal ones. The depressed and non-depressed samples were then compared, and the results did not reach significance, although a marginal value was found, which points to a tendency of stronger Truth Effect for the non-depressed sample – as was expected. The main hypothesis was not confirmed, although there is a pattern, in the depressed sample, of a stronger Truth Effect in depressive sentences, comparing to the normal ones. Results are discussed and proposals for future studies and their implications to the comprehension of cognitive processes in depression and to the adjustment of therapeutic approaches are presented.
