Answer to Question 1

Answer: The argument centers on the concept of delay of reinforcement. A short delay between a response and a reinforcing stimulus promotes better responding; a longer delay is associated with less-effective reinforcement. The essence of the argument is that ADHD children show a steep delay gradient: a short delay strongly activates their behavior (leading to hyperactivity). ADHD is commonly noted in poor classroom performance, which reflects the sensitivity of these children to long delays of reinforcement (as is the case in a classroom).
