我们研究了哌醋甲酯对21名患有注意力缺陷多动障碍（ADHD）的男孩的任务持久性的影响，在他们暴露于可解决和不可解决的问题之后。男孩们每4天尝试解决10个不同的“找字游戏”，涉及药物（安慰剂vs. 0.3 mg/kg）和先前任务难度（可解决vs.不可解决）的交叉。结果显示，药物可以防止在安慰剂日出现的无法解决的问题后表现的下降。此外，与安慰剂相比，服用药物的男孩更有可能将失败归因于外部因素，而将成功归因于内部因素。本研究从认知动机状态机制的角度探讨了药物对ADHD男孩学业表现的影响。
We examined the effects of methylphenidate on the task persistence of 21 boys with attention-deficit hyperactivity disorder (ADHD), after they had been exposed to both solvable and insolvable problems. The boys attempted to solve 10 different find-a-word puzzles on each of 4 days, involving the crossing of medication (placebo vs. 0.3 mg/kg) and prior task difficulty (solvable vs. insolvable). The results revealed that medication prevented the decrement in performance following the insolvable problems that was evident with the placebo days. In addition, on medication compared with placebo, the boys were more likely to make external attributions for failure and internal attributions for success. The results are discussed in terms of the impact of medication on ADHD boys' performance as medicated by cognitivemotivational state mechanisms.
