Development of a computerised version of the Children's Gambling Task for the evaluation of affective decision-making in Brazilian preschool children Desenvolvimento de uma vers o computadorizada da Children's Gambling Task para avalia o da tomada de decis o afetiva em crian as pré-escolares brasileiras

Despite the large number of instruments developed to assess the more purely cognitive executive functions in Brazilian children, few studies have developed instruments for the assessment of the most motivational components of these functions. The primary aim of this study was to develop a computerised version of the Children's Gambling Task (CGT) to assess affective decision-making in preschoolers. The present study also aimed to investigate whether this version of the task is sensitive to developmental changes across the preschool period and to examine gender differences in decision-making. We administered the CGT and the Columbia Mental Maturity Scale (CMMS) to 137 Brazilian children between the ages of three and five years old. Age differences between three-and four-year-olds, but not between four-and five-year-olds were found. Gender differences were not found. From this preliminary study, the computerised version of the CGT for Brazilian child population proved to be suitable for Brazilian child population. Apesar do grande número de instrumentos desenvolvidos para avalia o das fun es executivas mais puramente cognitivas em crian as brasileiras, há poucos estudos que desenvolveram medidas para avalia o dos componentes mais motivacionais dessas fun es. O principal objetivo deste estudo foi desenvolver uma vers o computadorizada da Children's Gambling Task (CGT) para avalia o da tomada de decis o afetiva em crian as pré-escolares. Também se buscou avaliar se a vers o desenvolvida é capaz de discriminar grupos etários e examinar as diferen as entre gêneros na tomada de decis o. A vers o brasileira da CGT e a Escala de Maturidade Mental Colúmbia foram aplicadas em 137 crian as de três a cinco anos. Observou-se que crian as de quatro e cinco anos obtiveram desempenho superior às de três, entretanto n o houve diferen a entre o desempenho das crian as de quatro e cinco anos, nem entre meninos e meninas. A partir deste estudo preliminar, a CGT mostrou-se apta à utiliza o na popula o brasileira.
