Abstract(s)
A Memória de trabalho é um sistema com capacidade limitada, responsável pelo
armazenamento temporário e manipulação de informações durante a realização de tarefas
complexas. O modelo multicomponente de memória de trabalho é proposto com
subcomponentes especializados. O componente executivo central não possui capacidade de
armazenamento, sendo responsável por supervisionar, controlar e coordenar os demais
sistemas e é considerado um sistema atencional. Estudos revelam que as sintomatologias de
ansiedade são capazes de influenciar o desempenho da memória de trabalho, de forma
especifica, o componente executivo central. Esta pesquisa propôs investigar o impacto da
sintomatologia de ansiedade no componente executivo central da memória de trabalho, e leva
em consideração a população brasileira e portuguesa. A recolha de dados ocorreu por
conveniência, através da distribuição de um link online nas redes sociais. Os instrumentos de
avaliação utilizados foram: questionário sociodemográfico, tarefa N-Back e questionário de
sintomatologia psicopatológica (BSI – Brief Symptom Inventory). No geral, 58.40% dos
participantes apresentaram níveis de sintomatologia de ansiedade acima da média considerada
para população geral, sendo mais expressiva na população brasileira. Relativamente a tarefa NBack, não houve diferença significativa entre as populações. Não foram encontradas correlações
significativas entre as variáveis da investigação. Contudo, esses resultados indicam que a
sintomatologia de ansiedade e a nacionalidade não alteraram de forma significativa o
desempenho na tarefa N-Back. Em suma, as analises sugerem que não houve impacto sobre o
desempenho do executivo central.
Working memory is a system with limited capacity, responsible for the temporary storage and manipulation of information while performing complex tasks. The multicomponent working memory model is proposed with specialized subcomponents. The central executive componente does not have storage capacity, being responsible for supervising, controlling and coordinating the other systems and is considered an attentional system. Studies reveal that anxiety symptoms are capable of influencing working memory performance, specifically, the central executive component. This academic research proposed to investigate the impact of anxiety symptoms on the central executive component of working memory, and takes into account the brazilian and portuguese population. Data collection took place for convenience, through the distribution of an online link on social networks. The assessment instruments used were: sociodemographic questionnaire, N-Back task and psychopathological symptomatology questionnaire (BSI – Brief Symptom Inventory). Overall, 58.40% of the participants had levels of anxiety symptoms above the average considered for the general population, being more expressive in the brazilian population. Regarding the N-Back task, there was no significant difference between populations. No significant correlations were found between the research variables. However, these results indicate that anxiety symptoms and nationality did not significantly alter performance on the NBack task. In short, the analyzes suggest that there was no impact on the performance of the central executive.
