Problem: Create a discussion post response to: The Krentz et al. (2016) study looked at whether giving tokens as rewards could help adults with intellectual disabilities walk more. The researchers used an ABAB reversal design, where they switched between no rewards and token rewards to see if walking changed. John showed low walking during baseline, but his walking increased and stayed steady when tokens were given. Jerry also walked more during the token phases, but his results changed more from day to day. A functional relationship was shown because walking increased when the token system was used and decreased when it was taken away. To improve the study, the researchers could reduce the amount of attention given during baseline and add a follow-up phase to see if participants would keep walking after the rewards stopped.
