This study evaluated the effectiveness of a mercury switch as a self-monitoring device to improve the sitting posture of an adult male. The participant in this study was a 31 year old man who was blind, nonambulatory, and who had been classified in the moderate range of intellectual functioning and in the severe range of adaptive functioning due to physical impairments. After determining that music practice and listening to a game show on the television channel of a radio were powerful reinforcers, a multiple baseline across the two reinforcing activities was implemented. The participant wore a mercury switch inside of a baseball cap which activated a Casio keyboard during music practice and a radio during the independent leisure activity of listening to a game show. During the treatment condition, the keyboard and radio were activated automatically by upright sitting posture. Results indicated that the participant's sitting posture increased from an average of almost 0% correct upright posture during baseline to an average of 52% during treatment.
本研究评估了汞开关作为一种自我监测装置对改善成年男性坐姿的有效性。本研究的参与者是一名31岁的男性，他双目失明、无法行走，并且由于身体损伤，其智力功能处于中等范围，适应功能处于严重范围。在确定音乐练习和收听广播电视频道的游戏节目是强大的强化物之后，对这两项强化活动实施了多基线设计。参与者在棒球帽内佩戴一个汞开关，在音乐练习期间该开关会激活卡西欧键盘，在收听游戏节目的独立休闲活动期间会激活收音机。在治疗条件下，键盘和收音机通过直立坐姿自动激活。结果表明，参与者的坐姿从基线期间平均几乎为0%的正确直立姿势增加到治疗期间的平均52%。
