Abstract
There has been much research into community living skills including leisure, cooking, shopping, and so forth for persons with developmental disabilities. Research in the shopping skills has been one of the fundamental research themes for teachig community living skills. The present study examined techniques for the formation of lining up to buy goods at the cashier's desks in a supermarket and two convenience stores. A boy with developmental disabilities (15-years-old) was trained to line up at the cashier's desks. The skills of lining up at the desks consisted of three subordinate behaviors as follows: a) locating himself behind the last shopper in the line, b) moving up to the front after that shopper took steps forward, and c) starting to pay by cash in his turn. Three training steps (1, 2, & 3) were all conducted in simulation settings. In training 1, pointing and verbal praise were used. In training 2, a ground paper, just like a pedestrian crossing, was stuck on the floor, and also, in training 3, five patterns of lines were introduced for the formation of flexible lining up at the desks. On the other hand, the generalization was evaluated in three real settings. Before training, the student often broke into the queue in both simulation and real settings. However, he could line up appropriately at the cashier's desks after training. The results of the generalization data in vivo would suggested that especially the training of some patterns of lines in the simulation setting was effective.
