What might an internal processing deficit mean in kids with DCD?

• A. Variances in activation patterns during motor tasks
• B. Impaired executive function
• C. Decreased ability to predict sensory consequences of motor commands
• D. Cerebellar involvement

Answer: (B)

Internal processing deficits refer to difficulties in the cognitive steps that plan, organize, monitor, and adjust actions. In kids with DCD, this often shows up as impaired executive function—problems with planning the sequence of a movement, holding and following multi-step instructions in working memory, shifting strategies when a task gets hard, and inhibiting distractions while performing a motor task. Because motor skills require coordinating thoughts and actions quickly and flexibly, weaknesses in these cognitive control processes can make movement feel less smooth or more effortful, even when the basic muscles and reflexes are fine.

So, an internal processing deficit is best understood as an executive function problem that disrupts the planning and regulation of movements. The other options point to neural activation patterns, the ability to predict sensory consequences of a command, or cerebellar involvement—relevant concepts but not the direct reflection of internal cognitive control that underlies this description.
