Motor functioning, exploration, visuospatial cognition and language development in preschool children with autism

Area of Science:

• Developmental Psychology
• Neurodevelopmental Disorders
• Cognitive Science

Background:

• Understanding developmental trajectories requires assessing inter-domain influences.
• Early fine motor skills, visuospatial cognition, exploration, and language are key developmental areas.
• Autism Spectrum Disorder (ASD) and other Developmental Delays/Disorders (DD) present unique developmental pathways.

Purpose of the Study:

• To examine longitudinal relationships between early fine motor functioning, visuospatial cognition, exploration, and language development.
• To compare these relationships in preschool children with ASD versus those with other DD.
• To investigate the role of exploration in these developmental domains.

Main Methods:

• Longitudinal study of preschool children with ASD (n=46 at T2) and DD (n=121 at T2).
• Subgroup analysis (n=50) focused on exploratory behavior.
• Assessment of fine motor skills, visuospatial cognition, exploration, and language (receptive/expressive).

Main Results:

• Fine motor functioning predicted language in both ASD and DD groups.
• Fine motor skills related to visuospatial cognition (both groups) and exploration (ASD group only).
• Visuospatial cognition and exploration measures correlated with receptive and expressive language in both groups.

Conclusions:

• Cognitive development is influenced by the interplay of multiple systems, aligning with embodied cognition theory.
• Interventions should consider the interconnectedness of motor, spatial, and language skills.
• Clinicians and researchers must view cognition as emergent from interacting systems.
