I kept many journals detailing Lucas's behavior after being diagnosed with autism. I have about 10 times as many documents pertaining to the 2-year home-based ABA program that we implemented. While reading through one of the early journals, I found this entry. Interestingly, this entry describes how I used a reinforcer (the identical apple cards) to reinforce Lucas's compliance with a task ("Match same.") Keep in mind, this was before we had any ABA training! Kind of cool!

"I set Lucas up at a coffee table with chair. I had Memory Game out that has matching picture cards. I'd set up 4 picture cards and hold one up that matched one of the four. I'd say "Match same." He resisted fiercely at first. Then, he saw the 2 apple cards. He liked them. When I took them from him to do "Match same," he'd cry but pick the right card. I'd give him the apple cards between games. With each successive match same game, he'd cooperate a lttle better. I continued to give him apple cards between each game. He correctly matched same each game (six times.)"
