Abstract: Resumo O construto Funcoes Executivas (FE) e um grupo de processos composto por multiplos componentes, porem ainda e insuficiente definido e operacionalizado. Podem ser considerados, pela participacao de processamentos emocionais, “frios” e “quentes”. O objetivo deste estudo foi correlacionar o construto Tomada de Decisao (TD), considerado uma FE “quente”, avaliado pelo Iowa Gambling Task (IGT), com outros componentes executivos avaliados pelos Teste Wisconsin de Classificacao de Cartas (WSCT), do Trail Making Test (TMT) e do Hayling Test. Em relacao ao desempenho global do IGT, somente foi encontrada relacao inversa com o tempo da parte B do Hayling Test, sugerindo que a velocidade de inibicao pode se relacionar diretamente com uma TD vantajosa. Foram encontradas correlacoes inversas entre o desempenho no primeiro bloco do IGT e outros escores dos tres instrumentos de FE, indicando um processamento distinto no inicio deste paradigma. Uma possivel hipotese e que mecanismos explicitos mais necessarios nas outras tarefas executivas poderiam ter uma associacao negativa com o desempenho no inicio do IGT, em que um processamento implicito e emocional e privilegiado. Sugerem-se estudos sobre a relacao do construto mensurado pelo IGT com outras FE consideradas “quentes”. © Cien. Cogn. 2012; Vol. 17 (1): 094-104.

Abstract The “executive functions” (EF) construct is a set of processes with many components, still insufficiently defined and operationalized. They can be considered, for the participation of emotional processing, “cold” and “hot”components. This study aimed to correlate the construct decision-making (DM), taken as a “hot” EF, as assessed by the Iowa Gambling Task (IGT), together with other executive components, assessed by Wisconsin Card Sorting Test (WSCT),Trail Making Test (TMT) and Hayling Test. Regarding to the total performance in IGT, the only finding was an inverse correlation with the time score of Hayling’s part B. It suggests that speed processing of inhibition can be directly related to an advantageous DM. Inverse correlations were found between the performance on the first block of IGT and the scores of other three EF tests, indicating a different processing in the beginning of this paradigm. It is possible that explicit mechanisms more necessary in other executive tasks might have a negative association with the performance in the earlier sections of the IGT, in which implicit and emotional processing is privileged. Studies about the relationship between the IGT’s main construct and other “hot” EF should be conducted. © Cien. Cogn. 2012; Vol. 17 (1): 094-104.
