On the ability of children with developmental coordination disorder (DCD) to inhibit response initiation: the simon effect.
The ability of children with developmental coordination disorder (DCD) to inhibit the initiation of an incorrect manual response urge was examined using a typical Simon task. While the size of the Simon effect was the same for both DCD (N = 20) and Control (N = 20) groups of children, showing no difference with respect to the time needed to complete the inhibition an unwanted response, children with DCD produced significantly more errors of the type which reflected a reduced ability to successfully effect the inhibition operation when it was required. This result is consistent with some earlier findings pointing to an inhibitory deficit for children with DCD (Wilson & Maruff, 1999).
