This study examined the relationship between imitation, motor movement, and language skill in 70 children with developmental disabilities. Four primary research questions were addressed: 1) What are the imitation, motor movement, and language profiles of young children with developmental disabilities?; 2) What is the relationship between imitation skill, motor movement, and language skill?; 3) ...

Previous research has shown an association between children's development of psychosocial and motor skills. This study evaluated the development of these skills in 301 three-year-old deaf and hard of hearing children (M: 37.8 months) and considered a range of possible predictors including gender, birth weight, age at first fitting with hearing devices, hearing device used, presence of additiona...

Impaired motor coordination is prevalent in children with Autism Spectrum Disorders (ASD) and affects adaptive skills. Little is known about the development of motor patterns in young children with ASD between 2 and 6 years of age. The purpose of the current study was threefold: (1) to describe developmental correlates of motor coordination in children with ASD, (2) to identify the extent to wh...

The development of visuomotor control in sequential pointing was investigated in 6- to 10-year-old children and in adults. In 3 experiments we manipulated task difficulty by changing the number, the size, and the spacing of the targets in the sequences. In Experiment 4, only 1 movement was required; we varied independently the distance between targets and the distance of the starting point from...

Recent evidence indicates that 6-month-old infants' mental rotation of objects profits from prior manual experience, whereas observational experience does not have the same beneficial effect. The current study investigated whether older infants, at 8 and 10 months, succeed in a mental rotation task after observational experience only and whether performance is related to infants' motor developm...
