Three groups of learning disabled boys--hyperactives, normoactives, and hypoactives--were studied in grade school, reevaluated at fourteen. At follow-up, all three groups remained at disadvantage to controls on academic and cognitive measures and on complex reaction time. Half the hyperactives had experienced major conflicts with authority, and over a third of hypoactives exhibited psychologically disturbing behaviors. Mental health of normoactives appeared comparable to controls.
三组学习障碍男孩——多动型、正常活动型和低活动型——在小学阶段接受了研究，并在14岁时进行了重新评估。在随访中，所有三组在学业和认知测试以及复杂反应时间方面仍比对照组处于劣势。一半的多动型男孩曾与权威发生重大冲突，超过三分之一的低活动型男孩表现出心理困扰行为。正常活动型男孩的心理健康状况似乎与对照组相当。
