This study investigated the effect of methylphenidate (Ritalin) on the selective attention of hyperactive children designated as favorable or adverse responders to stimulant medication. Using a type II incidental learning paradigm, it was found that children in the drug condition recalled more central and less incidental stimuli than those children in the placebo condition. While no differential effects on recall were found for responder type, methylphenidate did affect the spontaneous overt labeling of central stimuli by the favorable responder group. Results were interpreted in terms of the role of methylphenidate in narrowing the focus of attention. Implications for the classification of hyperactive children as favorable and adverse responders were also discussed.
本研究调查了哌甲酯（利他林）对被指定为对兴奋剂药物反应良好或不良反应的多动症儿童选择性注意力的影响。采用II型附带学习范式，发现用药组儿童比安慰剂组儿童回忆起更多的核心刺激和更少的附带刺激。虽然未发现反应类型对回忆有差异影响，但哌甲酯确实影响了反应良好组对核心刺激的自发明显标记。研究结果根据哌甲酯在缩小注意力焦点方面的作用进行了解释。还讨论了将多动症儿童分类为反应良好和不良反应者的意义。
