We investigated the effects of an intermittent reinforcement procedure on maintenance of verbal/nonverbal correspondence with nutritious snack choices in a day-care setting. Nutritious snack choices were first established using correspondence training procedures in a multiple baseline across three children. Withdrawal of the procedures with one subject led to loss of appropriate responding, suggesting the need for a maintenance strategy. The intermittent reinforcement procedure was implemented in a multiple baseline across subjects. Nutritious snack choices were observed consistently during the intermittent reinforcement condition and the subsequent extinction condition.
我们研究了间歇性强化程序对在日托环境中维持与营养零食选择的言语/非言语对应关系的影响。首先，通过在三名儿童中进行多基线对应训练程序来确立营养零食选择。对一名受试者撤销该程序导致适当反应的丧失，这表明需要一种维持策略。间歇性强化程序在受试者间多基线设计中实施。在间歇性强化阶段及随后的消退阶段，均持续观察到对营养零食的选择。
