Abstract
The claim that impulsiveness associated with hyperactivity is the result of deficits in inhibition of responses over time was examined. The cognitive style of hyperactive children was studied under two conditions. As in previous studies hyperactive children appeared impulsive (i.e. gave shorter latencies and made more errors than controls) under conditions where this style led to shorter trials. In contrast, in a revised condition where each error led to an enforced/fixed trial length, hyperactive children waited as long as controls before responding, but still made more errors. Hyperactive children withheld responses when this offered them the best chance of avoiding extra delay. They were however, unable to use the extra time provided as effectively as controls. The link between hyperactive children's aversion to delay and their poor use of time is discussed.
