Incidental learning and social‐communicative abilities in children with developmental language disorder: Further evaluating the implicit learning deficit hypothesis

What is already known on the subject Individuals with developmental language disorder (DLD) not only have linguistic problems but also impaired abilities in social and emotional domains. According to the implicit learning deficit hypothesis, these impairments are largely due to a compromised ability to incidentally or implicitly learn regularities of stimuli or events occurring in daily life. However, research examining this hypothesis has yielded mixed results. What this paper adds to existing knowledge This study contributes to the discussion about the presence or absence of a domain-general implicit learning deficit in individuals with DLD, and corresponding potential clinical implications. For this, in addition to measures of language, emotion recognition and social abilities, a novel incidental learning task was used that was held to provide a more process-pure measure of incidental and implicit learning compared to previous research. The collective results do not support the claim of a domain-general implicit learning deficit underlying the social-communicative and -emotional problems in DLD. What are the potential or actual clinical implications of this work? Current interventions to improve language, social and emotional abilities in children with DLD are largely based on relatively effortful strategies involving explicit instruction and feedback. The present evidence of intact incidental and implicit learning abilities supports the examination of possible novel interventions that are based on relatively effortless implicit learning strategies, which may be more in line with how these abilities are acquired in daily life.
