LOPEZ-RAMON, María Fernanda; LEDESMA, Rubén; INTROZZI, Isabel  and  URQUIJO, Sebastián. Implicit Learning of Artificial Grammars in children: effect of the length, the valence and the superficial format of the strings. Psic [online]. 2007, vol.8, n.2, pp. 121-130. ISSN 1676-7314.

The studies that were done in children in relation with the type of representations that are involved with the product of the Implicit Learning (AI) are scarce. For it, the work is focused in the analysis of the effect that some factors, that have not yet been analyzed, have in the identification of the correct items in AI tests: (1) the length of the grammatical strings, (2) the valency of the item and (3) the type of superficial format, in a sample of 7 and 8-year-old children. We evaluated 30 children of the third year of EGB of the Provincial School N ° 27 of Mar del Plata city, Argentina, with the Reber´s Artificial Grammar Paradigm. The results shows that children discriminate better the grammatical correct strings in the tests of implicit learning in the cases that the strings have a positive valency; and in the other way round, the children obtain worse results in the identification of test items with negative valency. The results also indicated that the type of format (alphabetical or figurative) does not influence the correct identification of the items of the test. The obtained information is valuable for the description of the representations involved in the acquisition and transference of the AI during the infancy and involves a contribution for the design and selection of the reagents most adapted for the evaluation of these representational dimensions in the planning of future studies.
