Promoting Executive Functioning in Children with Autism Spectrum Disorder Through Mixed Martial Arts Training.

The present study evaluated the effectiveness of a mixed martial arts (MMA) intervention in improving executive functions (EFs) in a sample with autism spectrum disorder (ASD). School-aged children with ASD were randomly assigned to a MMA intervention group or a waitlist control (WLC) group. The intervention featured a 26-class program over a 13-week period; the WLC group did not participate in any martial arts between pre- and post-test. Results indicated that the MMA group had significantly better EFs at post-test compared to the WLC group. The intervention appeared to be efficacious in meeting its goals of improving the executive functioning of children with ASD. The present study extends the current literature on the malleability of EFs among children with ASD.

Language facilitates event memory in early childhood: Child comprehension, adult-provided linguistic support and delayed recall at 16 months.

Adult-provided supportive language facilitates memory for the past in preverbal and verbal children. Work conducted with 18-month-olds indicates that children benefit from supportive adult language when tested after a 4-week delay but not when tested immediately after sequence demonstration; moreover, findings reveal that supportive language provided only at test may be more facilitative of recall after a delay relative to supportive language provided only at encoding. In the present study, we examined whether child language comprehension abilities moderated the extent to which preverbal children benefitted from supportive language provided at encoding and test. The findings indicated that child language comprehension and supportive language provided at encoding were unassociated with performance at baseline or immediate imitation; however, the moderating effect of child language comprehension on adult-provided supportive language at encoding and test was observed after a 1-week delay. Correlations revealed continuous associations between general comprehension scores and recall performance after the 1-week delay on sequences presented in the most supportive condition at encoding. Taken together, the presented findings reveal that the complex interplay between language and cognition is established in early childhood, with foundational relations emerging before children are capable of verbally reporting on the past.

Adult language use and infant comprehension of English: associations with encoding and generalization across cues at 20 months.

Adult-provided language shapes event memory in children who are preverbal and in those who are able to discuss the past using language. The research conducted to date, however, has not yet established whether infant language comprehension abilities moderate the extent to which preverbal infants benefit from adult-provided supportive language. The present study was conducted to address this question by examining immediate imitation and 1-week delayed generalization across cues in 20-month-old infants as a function of (a) variability in adult-provided linguistic support at encoding and test, (b) infant language comprehension abilities, and (c) their interaction. The provision of supportive adult language at encoding and test was associated with delayed generalization across cues although supportive adult language at encoding did not influence performance at immediate imitation. Infant language comprehension abilities were associated with performance at immediate imitation and delayed generalization across cues. In addition, infant language comprehension abilities moderated the extent to which infants benefited from adult-provided supportive language at encoding and test. The findings contribute to the literature by demonstrating that adult language use and infant language comprehension are independently and differentially associated with immediate imitation and 1-week delayed generalization across cues but also serve to jointly structure event memory in the second year of life.
