>First, we attempted to transfer stimulus control from the woman in sandals to pictures of women in sandals by using a pairing procedure; however, no transfer of control was observed after 50 pairing sessions.
>Second, we found that continuous access to snacks, leisure items, attention, and a video of a woman in sandals eliminated the behavior; however, the intervention was impractical for long-term implementation.
>Alex wore a backpack with a strap (0.6 m long) attached to each side of the top. When Alex initiated the target response, a female therapist followed him and gently pulled on the straps and walked him to the corner of the room. If he attempted to move away or drop to the floor, the therapist gently pulled up on the backpack straps.
>After a 1-min time-out period had passed, Alex again was allowed to walk around the room. Fading entailed eliminating first one strap, then the other. When both straps were eliminated, the therapist responded to attempts to drop to the floor by pulling up on a small loop at the top of the backpack. After both straps were eliminated, generalization sessions were conducted in the work area, cafeteria, and outside courtyard in the presence of four different women wearing sandals. The therapist remained nearby during generalization sessions and would have walked over to implement the RI/TO procedure had Alex initiated the problem behavior.
