Abstract(s)
O presente trabalho tem como objectivo principal “Perceber a influência do
envelhecimento em tarefas de memorização”. Para tal, estudou-se o desempenho de
idosos normais em diversas tarefas de memorização. A amostra do estudo é composta por
um grupo de idosos saudáveis, sendo 23 homens (60,5%) e 15 mulheres (39,5%), que
perfaz 38 idosos. Recorreu-se ao método de investigação observacional, mais
especificamente transversal, não tendo havido manipulação experimental da parte do
investigador. Para analisar a relação entre a idade e o desempenho dos sujeitos nas tarefas
explanadas foi realizada uma comparação de médias, desta forma, aplicou-se o teste
paramétrico One-Way ANOVA, de comparação de médias para amostras independentes.
foi assegurada a normalidade da distribuição da Variável Dependente - Quantitativa nas
diferentes amostras (teste de Shapiro-Wilk) e a homogeneidade de variâncias (teste de
Levene), sendo que nos casos em que não se observou normalidade de distribuição, estas
não revelaram violações graves do presente pressuposto. Os resultados são discutidos e
apresentados com base em hipóteses levantadas ao longo do trabalho e enquadrados à luz
da fundamentação teórica realizada. Verificou-se uma relação negativa significativa de
baixa intensidade, entre a Idade e a Memória Verbal com Interferência. Ou seja, quanto
maior a idade, menor o resultado em Memória Verbal com Interferência. Por conseguinte,
não houve relação entre a idade e as Memórias (Verbal Imediata e de Digitos). Ao longo
do trabalho não se verificou-se uma correlação significativa entre a escolaridade e o
desempenho na maior parte das variáveis avaliadas, querer isso dizer que, não há uma
relação entre a escolaridade e o resultado em nenhuma das três provas de memorização.
The present work has as main objective "To perceive the influence of the aging in tasks of memorization". For this, we studied the performance of normal elderly in several memory tasks. The sample of the study is composed of a group of healthy elderly people, being 23 men (60.5%) and 15 women (39.5%), which makes up 38 elderly people. We used the method of observational research, more specifically transversal, and there was no experimental manipulation on the part of the researcher. In order to analyze the relationship between the age and the performance of the subjects in the tasks explained, a comparison of means was performed, in this way, the One-Way ANOVA parametric test was applied, comparing means for independent samples. the distribution of the Dependent - Quantitative Variable in the different samples (Shapiro-Wilk test) and the homogeneity of variances (Levene test) were assured, and in those cases in which no normal distribution was observed, they did not reveal serious violations of this assumption. The results are discussed and presented based on hypotheses raised throughout the work and framed in the light of the theoretical foundation. There was a significant negative relationship of low intensity between Age and Verbal Memory with Interference. That is, the greater the age, the lower the result in Verbal Memory with Interference. Therefore, there was no relation between age and Memories (Immediate Verbal and Digits). Throughout the study, there was no significant correlation between schooling and performance in most of the evaluated variables, meaning that there is no relationship between schooling and outcome in any of the three memorization tests
