title: Judgment of action capabilities in children at risk for developmental coordination disorder.
abstract: OBJECTIVE
  To evaluate the ability to accurately perceive the limits of action capabilities in children at risk for developmental coordination disorder (DCD).
  
  
  METHODS
  In Study 1, 9 to 12-year-old children (mean = 10.6 years, SD = 1.09) were identified as at risk for DCD and the accuracy of their perceptual judgments was compared with the judgments of a group of typically developing children (TDC). Two judgment tasks were used: Maximum vertical reach and maximum sitting height. Study 2 tested the hypothesis that a significant correlation would be found between a specific movement task and a related judgment task. Participants were randomly selected (n = 24) 10 and 11-year-old children (mean = 10.5 years, SD = 0.51).
  
  
  RESULTS
  Magnitude of judgment error (absolute error) on all tasks was significantly (p < 0.05) greater in the DCD group than in the TDC group. Study 2 revealed a significant (p < 0.05) correlation between the movement task and the related perceptual task (r = 0.70).
  
  
  CONCLUSIONS
  Compared to a typically developing group, children at risk for DCD made less accurate judgments of the limits of their action capabilities. The accuracy of a perceptual judgment was found to correlate with a related movement skill.
