“…While only five of these studies used hypothetical rewards, they found no difference in effect sizes between studies that used real or hypothetical rewards. Although the association seen in our study ( r = −0.47) was larger than that estimate, a similar association magnitude has been reported in some studies of discounting in children (e.g., Cuskelly, Zhang, & Hayes, 2003) though not in all (e.g., Kendall, Zupan, & Braswell, 1981). Thus, it is possible that over many studies of ADHD, IQ may account for the observed results.…”

Background A key underlying process that may contribute to attention-deficit/hyperactivity disorder (ADHD) involves alterations in reward evaluation, including assessing the relative value of immediate over delayed rewards. This study examines whether children with ADHD discount the value of delayed rewards to a greater degree than typically developing children using a delay discounting task. Methods Children aged 7–9 years diagnosed with ADHD and controls completed a task in which they chose between a hypothetical $10 available after a delay (7, 30, 90 and 180 days) versus various amounts available immediately. Results ADHD participants discounted more steeply than controls. However, this effect did not survive covarying of IQ. Conclusions ADHD is associated with a steeper delay gradient when contemplating hypothetical later rewards, but not independently of IQ. The interplay of cognitive processing and IQ with reward evaluation in ADHD requires further exploration.

“…Cuskelly et al . () compared waiting time of children with Down syndrome with that of a mental age (MA)‐matched group of typically developing children and found that the children with Down syndrome had significantly shorter waiting times than the comparison group. In a study of adults with Down syndrome, Cuskelly et al .…”
