Children who are diagnosed with attention deficit hyperactivity disorder (or who engage in behavior consistent with such a diagnosis) are often prescribed stimulant medications for hyperactive or inattentive behaviors. However, the mechanisms by which stimulant medications affect individuals' behavior are rarely evaluated. The purpose of the current study was to evaluate the effects of stimulant medication on response allocation when antecedents and consequences were held constant and equated. Results indicated that the presence of an amphetamine medication (Adderall) influenced response allocation across two concurrently available responses while all other stimulus conditions were held constant.
被诊断患有注意力缺陷多动障碍的儿童(或其行为符合此类诊断),常因多动或注意力不集中行为而被开了刺激性药物。然而,刺激性药物影响个体行为的机制很少被评估。本研究的目的是在前提条件和后果保持不变且相等的情况下,评估刺激性药物对反应分配的影响。结果表明,苯丙胺药物(阿得拉)的存在影响了在两个同时可用反应之间的反应分配,而所有其他刺激条件保持不变。
