RESUMO

The influence of the frequency of reading and writing habits (FRWH) on cognition has been investigated by several studies in the literature. However, the implications of FRWH on executive development, intelligence, and academic achievement are not yet clear in adolescents with healthy development. The aim was to verify whether there are differences in executive functions, intelligence, and academic achievement between adolescents with high and low FRWH. Moreover, we aimed to investigate if there are differences in the parental FRWH between adolescents with high and low FRWH. The sample was composed of 47 healthy adolescents, n = 24 with high FRWH and n = 23 with low FRWH. Adolescents with higher FRWH had better performance on measures of vocabulary, Speech Act analysis, and Oral Narrative Discourse. Therefore, a high FRWH has a positive influence on the cognitive development of healthy adolescents, especially with regard to pragmatic language. However, adolescents with low FRWH performed better than those with a high FRWH on an automatic counting task. The interpretation of cognitive performance and academic achievement scores in neuropsychological assessment should consider the FRWH of parents and adolescents. This factor should be targeted by early stimulation interventions to help adolescents achieve the highest possible levels of global development.

RESUMO

During normal aging there is a decline in cognitive functions that includes deficits in oral discourse production. A higher level of education and more frequent reading and writing habits (RWH) might delay the onset of the cognitive decline during aging. This study aimed at investigating the effect of education and RWH on oral discourse production in older adults. Picture-based narratives were collected from 117 healthy adults, aged between 51 and 82 years (68.6 ± 6.38) with 0-20 years of formal education (10.1 ± 5.69). Measures of macro, microlinguistic and modalizations were computed and entered as dependent variables in hierarchical regression analyses that included age, education and RWH as regressors. Results revealed that higher education explained a better performance at the macrostructure and microstructure dimensions. Higher frequency of RWH explained the production of fewer modalizations. These results demonstrate the positive effect of education and RWH in oral discourse production in older adults. Therefore, higher attention should be given to these social factors.

RESUMO

Verbal fluency tasks are widely used in (clinical) neuropsychology to evaluate components of executive functioning and lexical-semantic processing (linguistic and semantic memory). Performance in those tasks may be affected by several variables, such as age, education and diseases. This study investigated whether aging, education, reading and writing frequency, performance in semantic judgment tasks and depression symptoms predict the performance in unconstrained, phonemic and semantic fluency tasks. This study sample comprised 260 healthy adults aged 19 to 75 years old. The Pearson correlation coefficient and multiple regression models were used for data analysis. The variables under analysis were associated in different ways and had different levels of contribution according to the type of verbal fluency task. Education had the greatest effect on verbal fluency tasks. There was a greater effect of age on semantic fluency than on phonemic tasks. The semantic judgment tasks predicted the verbal fluency performance alone or in combination with other variables. These findings corroborate the importance of education in cognition supporting the hypothesis of a cognitive reserve and confirming the contribution of lexical-semantic processing to verbal fluency.(AU)

As tarefas de fluência verbal são amplamente empregadas na clínica neuropsicológica para avaliar os componentes de funções executivas e processamento léxico-semântico (linguagem e memória semântica). O desempenho nessas tarefas pode ser influenciado por diferentes variáveis, como idade, escolaridade e diferentes patologias. Este estudo investigou se a idade, escolaridade, frequência dos hábitos de leitura e escrita, o desempenho em tarefas de julgamento semântico e sintomas de depressão predizem os desempenhos em tarefas de fluência verbal de critério livre, fonêmico-ortográfico e semântico. Participaram desse estudo 260 adultos saudáveis entre 19 e 75 anos. Foi utilizada a correlação de Pearson e da análise de regressão múltipla. As variáveis analisadas foram associadas em diferentes modelos combinatórios e apresentaram distintos níveis de explicação de acordo com o tipo de fluência verbal. A escolaridade foi a variáveis que melhor contribuiu para a explicação do desempenho nas tarefas de fluência verbal, seguida pela idade, principalmente na tarefa fonêmico-ortográfica. O desempenho nas tarefas de julgamento semântico predisse a performance da fluência verbal isoladamente ou em combinação com as demais variáveis. Esses resultados corroboram a importância da escolaridade na cognição, sustentando a hipótese da reserva cognitiva e confirmam a implicação do processamento léxico-semântico na fluência verbal.(AU)
