Resumo: The aim of this study is to investigate the effect of prolonged cognitive demand in Event Related Potential (ERP) modulation in inhibitory control paradigm. Data were collected in 19 right-handed volunteers with mean age of 21.21 (±1,77) years who performed the Go/NoGo paradigm for 50 minutes, with synchronized electroencephalogram recording to obtain the ERPs. The time on task effect induced significant changes in subjective variable, cognitive performance and maximum amplitudes of the N2 and P3 component. Our results suggest that when our brain is subjected to extensive cognitive demands, there are adaptations to maintain the behavioral performance through strategy reallocation of energy resources.

Os dados foram coletados em 19 voluntários destros, com a média de idade de 21,21 (±1,77) anos, que realizaram o paradigma do Go/NoGo durante 50 minutos, com gravação sincronizada do eletroencefalograma para obtenção dos ERPs. O efeito do tempo de realização da tarefa provocou alterações significativas nas variáveis subjetivas, de desempenho cognitivo e nas amplitudes máximas dos componentes N2 e P3. Nossos resultados sugerem que quando nosso cérebro está submetido a demandas cognitivas extensas, ocorrem adaptações para a manutenção do desempenho comportamental através da estratégia de realocação de recursos energéticos.Instituto de Psicologia - Universidade de Brasília2019-02-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.unb.br/index.php/revistaptp/article/view/2329710.1590/0102.3772e3527Psicologia: Teoria e Pesquisa; Vol. 35 (2019)Psicologia: Teoria e Pesquisa; Vol. 35 (2019)Psicologia: Teoria e Pesquisa; Vol. 35 (2019)Psicologia: Teoria e Pesquisa; v. 35 (2019)1806-34460102-3772reponame:Psicologia (Universidade de Brasília.
