The main objective of this study is to verify whether there are differences in bilingual (Brazilian Portuguese and Spanish speakers) and monolingual students (Brazilian Portuguese speakers) as the components of executive functions and meta-language. In order to test the hypothesis that bilingualism impacts in the development of ex-ecutive functions components and metalanguage, twenty-three (23) bilingual and 23 monolin-gual children, forty-six (n = 46), equally distributed according to age and school year - from first (1st) to third (3rd) year of elementary school), were examined through verbal and non-verbal tasks of executive functions and tasks of metalanguage. Verbal tasks that assess com-ponents of executive functions were Child Hayling Test, the subtests of Children?s Test of Pseudowords and Children Digit Span Test. Non-verbal tasks were Five Digit Test, Bells Test, Corsi Block Test and Trail Making Test for Children. Language Arbitrariness Test and Symbol Substitution Test were applied to evaluate the metalanguage. Forty-two (42) measures were derived from the nine proposed tasks, among which eighteen (18) have presented statis-tically significant differences, fourteen (14) have showed bilingual and four (4) monolingual advantage. Through the Mann Whitney statistical test, it was observed that there were no dif-ferences in the comparison between groups as the metalanguage measures. In general, consid-ering the measures that evaluate the components of the executive functions, the bilingual group has overcome the monolingual group in most of the found differences. It was found that there are differences between bilinguals and monolinguals regarding timing for adaptation to changes (cognitive flexibility). / A partir de uma perspectiva psicolingu?stica, este estudo transversal se insere em uma interface entre bilinguismo infantil e cogni??o. O objetivo principal deste estudo ? investigar se h? diferen?as em escolares bil?ngues (falantes de portugu?s brasileiro e espanhol) e monol?ngues (falantes de portugu?s brasileiro) quanto a componentes das fun??es executivas e ? metalinguagem. A fim de testar a hip?tese de que o bilinguismo impacta no desenvolvimento dos componentes das fun??es executivas e da metalinguagem, 23 crian?as bil?ngues e 23 monol?ngues (n=46), distribu?das igualmente conforme idade e ano escolar (do 1? ao 3? ano do Ensino Fundamental), foram examinadas por meio de tarefas verbais e n?o verbais de fun??es executivas e de tarefas de metalinguagem. As tarefas verbais que avaliam componentes das fun??es executivas foram Teste Hayling Infantil, subtestes Span de Pseudopalavras e de d?gitos. J? as tarefas n?o verbais foram Teste dos Cinco D?gitos, Teste de Cancelamento de Sinos, Teste Blocos de Corsi e o Teste de Trilhas Infantil. As tarefas de Arbitrariedade da L?ngua e Substitui??o de S?mbolos foram aplicadas para avaliar a metalinguagem. Dentre as nove tarefas propostas, derivaram-se 42 medidas, entre as quais 18 apresentaram diferen?as estatisticamente significativas (14 apontam vantagem bil?ngue e quatro vantagem monol?ngue). Por meio do teste estat?stico Mann Whitney, observou-se que n?o houve diferen?as na compara??o entre grupos quanto ?s medidas de metalinguagem. De modo geral, em rela??o ?s medidas que avaliam os componentes das fun??es executivas, o grupo bil?ngue superou o grupo monol?ngue na maioria das diferen?as encontradas. Constatou-se que h? diferen?as entre bil?ngues e monol?ngues quanto ao timing para adapta??o a mudan?as (flexibilidade cognitiva).
