Twenty hyperactive children were divided into two groups of 10 volunteers. Group 1 was taken off its medication (methylphenidate) for two weeks and group 2 was kept on its medication at the usual dosage. About one week following the cessation of medication subjects from both groups heard a story and were shown some pictures illustrating events in the story. They were then tested on their memory for this material. One week later their delayed retention was tested. Both immediate and delayed retention was better in those children who remained on medication. This was especially true for the incidental material.
20名多动症儿童被分成两组，每组10名志愿者。第一组停药（哌甲酯）两周，第二组继续按常规剂量服药。停药后约一周，两组受试者听了一个故事，并观看了一些说明故事中事件的图片。然后对他们对这些材料的记忆进行测试。一周后测试他们的延迟记忆。继续服药的儿童的即时记忆和延迟记忆都更好。对于附带材料来说尤其如此。
