Implicit learning in children and adolescents with mental retardation.

The literature on implicit learning in persons with mental retardation is scarce and contradictory with respect to the relationship between degree of intellectual disability and impact of implicit-learning processes on performance. We examined children and adolescents with mild or moderate mental retardation and typically developing children matched on MA with regard to their implicit learning. Individuals with mental retardation modified their behavior after an implicit training procedure in a way similar to MA- or CA-matched controls. The impact of implicit learning did not vary as a function of IQ or age. However, some differences appeared between groups in their explicit remembering of the training conditions. The theoretical implications of these results are discussed.
