In the present study the effects of withdrawal of food, withdrawal of attention, and the simultaneous withdrawal of food and attention on the rate of self-injurious behavior of three profoundly retarded girls during mealtime were investigated. The two treatments that prevented eating led to a marked reduction of self-injurious behavior. Application of the method allowing continuation of eating (withdrawal of attention) resulted in an increased rate of two subjects' self-injurious behavior and had little effect on the rate of self-injurious behavior of the third. An analysis of the data suggests that contingent interruption of meal consumption can reduce the behavior and that rates of self-injurious behavior vary as a result of reinforcement.
在本研究中，调查了禁食、不予关注以及同时禁食和不予关注对三名重度智障女孩用餐期间自伤行为发生率的影响。两种阻止进食的处理方法导致自伤行为显著减少。采用允许继续进食的方法（不予关注），两名受试者的自伤行为发生率增加，而对第三名受试者的自伤行为发生率影响不大。数据分析表明，进餐过程中的偶然中断可以减少该行为，并且自伤行为的发生率因强化作用而有所不同。
