Abstract :
[en] Objective. This study aims to compare verbal and motor implicit sequence learning abilities
in children with and without Specific Language Impairment (SLI). Methods. Forty-eight
children (24 control and 24 SLI) were administered the Serial Search Task (SST), which
enables the simultaneous assessment of implicit spoken words and visuomotor sequences
learning. Results. Results showed that control children implicitly learned both the spoken
words as well as the motor sequences. In contrast, children with SLI showed deficits in both
types of learning. Moreover, correlational analyses revealed that SST performance was
linked with grammatical abilities in control children but with lexical abilities in children with
SLI. Conclusion. Overall, this pattern of results supports the procedural deficit hypothesis
and suggests that domain general implicit sequence learning is impaired in SLI.
