Children with Attention Deficit Hyperactivity Disorder (ADHD) are more likely to choose impatiently than controls. Delay fading with an alternative activity, signaling the delay, or self-instruction, have been shown to increase self-control choice, but we know little about their generalization. The present study evaluated the effect of multipleexemplar training on the generalization of self-control choice across settings, behaviors, and time, in two, five-year-old boys with ADHD. We used a multiple-baseline-across-settings design. We trained selfcontrol choice across three settings, and we assessed post-training generalization in the fourth, novel setting. We accommodated each setting with different kinds of exemplars: reinforcers, discriminative stimuli, researchers, and conditions, during the delay of the larger reinforcer. Children showed self-control choice in the novel setting for more than 80% and maintained more than 60% at two-month follow-up. The multiple-exemplar training led ADHD children to generalize self-control choice. Future research should incorporate intra-category exemplar training and natural settings demonstrations.
Key words: generalization, self-control choice, multiple-exemplar, delay fading, ADHD.
