Children at Risk for Developmental Coordination Disorder: Judgement of Changes in Action Capabilities
Johnson, Daniel C.; Wade, Michael G.
Developmental Medicine & Child Neurology, v51 n5 p397-403 May 2009
In three separate manipulations, a group of children at risk for developmental coordination disorder (DCD; five males, seven females; mean age 11y 6mo [SD 6.8mo] who were at or below the 15th percentile on the Movement ABC) and a group of typically developing children (TDC; seven males, five females; mean age 11y 3mo [SD 6.8mo]) judged the limit of their standing horizontal reach (HR[subscript max]) under two conditions in which actual HR[subscript max] differed. The manipulations were: (1) one-hand versus two-hand reach; and (2) standard versus short effective foot-length; and (3) rigid versus compliant support surface. For the foot-length and support surface manipulations (but not for the hand manipulation), children correctly judged that their actual HRmax differed in the two conditions (p less than 0.05). On all three manipulations, TDC made significantly larger adjustments in their judgements than did children at risk for DCD (p less than 0.05). The TDC group adjusted their judgements in the appropriate direction on all three manipulations, whereas the DCD group adjusted in the appropriate direction for the foot-length manipulation only. The results suggest that children at risk for DCD are less adept at detecting changes in the limits of their action capabilities.
