We used an assessment that involved competing reinforcer dimensions in a concurrent-schedules arrangement to examine the effects of stimulant medication on impulsivity (i.e., sensitivity of choices to reinforcer immediacy relative to rate, quality, and effort) with 4 students with attention deficit hyperactivity disorder. The assessments were administered in the context of a double-blind, placebo-controlled, counterbalanced reversal design. Reinforcer immediacy was the most influential dimension for 3 of the students and the second most influential dimension for 1 of the students across placebo and medication conditions; medication did not affect these sensitivities.
我们采用了一种评估方法,该方法在同时呈现强化物维度的并行安排中,对4名患有注意力缺陷多动障碍的学生进行测试,以检验兴奋剂药物对冲动性的影响(即相对于强化物的速率、质量和努力程度,选择对强化物即时性的敏感度)。评估是在双盲、安慰剂对照、平衡反转设计的背景下进行的。在安慰剂和药物条件下,强化物即时性对3名学生来说是最具影响力的维度,对1名学生来说是第二最具影响力的维度;药物并未影响这些敏感度。
