چکیده انگلیسی


- Sequencing oromotor movements is correlated with joint attention in children with ASD.
- Multi-modal speech cues increased oromotor imitation performance in young children.
- Some verbal preschool children with ASD exhibit oromotor imitation deficits.

PurposeThis study examined the relationship between joint attention ability and oromotor imitation skill in three groups of young children with and without Autism Spectrum Disorder using both nonverbal oral and verbal motor imitation tasks. Research questions addressed a) differences among joint attention and oromotor imitation abilities; b) the relationship between independently measured joint attention and oromotor imitation, both nonverbal oral and verbal motor; c) the relationships between joint attention and verbal motor imitation during interpersonal interaction; and d) the relationship between the sensory input demands (auditory, visual, and tactile) and oromotor imitation, both nonverbal oral and verbal motor.MethodA descriptive, nonexperimental design was used to compare joint attention and oromotor skills of 10 preschool-aged children with ASD, with those of two control groups: 6 typically developing children (TD), and 6 children with suspected Childhood Apraxia of Speech (sCAS) or apraxic-like symptoms. All children had at least a 3.0 mean length utterance.ResultsChildren with ASD had poorer joint attention skills overall than children with sCAS or typically developing children. Typically developing children demonstrated higher verbal motor imitation skills overall compared to children with sCAS. Correlational analyses revealed that nonverbal oral imitation and verbal motor imitation were positively related to joint attention abilities only in the children with ASD. Strong positive relationships between joint attention in a naturalistic context (e.g., shared story experience) and oromotor imitation skills, both nonverbal oral and verbal motor, were found only for children with ASD. These data suggest there is a strong positive relationship between joint attention skills and the ability to sequence nonverbal oral and verbal motor movements in children with ASD. The combined sensory input approach involving auditory, visual, and tactile modalities contributed to significantly higher nonverbal oral and verbal motor imitation performance for all groups of children.ConclusionsVerbal children with ASD in this study had difficulties with both the social and cognitive demands of oromotor imitation within a natural environment that demanded cross-modal processing of incoming stimuli within an interpersonal interaction. Further, joint attention and oral praxis may serve as components of an important coupling mechanism in the development of spoken communication and later developing socialcognitive skills.
