30个家庭，包括两个父母和两个青春期的孩子，接受了高加工负荷连续操作测试CPT-IP，该测试要求在连续呈现的一系列刺激中识别相同的刺激对。本研究的目的是为有关注意在精神病理学，特别是精神分裂症和重大情感障碍中的作用的研究提供规范的数据。从30个家庭中收集的23个家庭的重新测试数据显示，CPT-IP是衡量注意力的可靠指标。研究发现，对空间刺激和语言刺激保持注意力的能力有很大的发展效应，这表明空间技能在儿童和青春期发展得最好，而语言注意能力往往在成年后达到顶峰。因素分析和家庭传递模式进一步表明，这两种类型的注意(空间和语言)是独立的，每一种都具有一定程度的遗传性。实验分心并没有破坏任何受试者的表现，事实上，倾向于改善青少年的表现，特别是对于稀少的刺激。我们的结论是，CPT-IP适用于成员在年龄和处理技能上存在很大差异的家庭。
Thirty families, consisting of two parents and two adolescent children, were tested on a high-processing load Continuous Performance Test, the CPT-IP, which required identification of identical stimulus pairs within a continuously presented series of stimuli. The purpose of this study was to provide normative data for research concerned with the role of attention in psychopathology, especially schizophrenia and major affective disorder. Retest data collected from 23 of the 30 families showed the CPT-IP to be a reliable measure of attention. A major development effect was found in capacity to sustain attention to spatial vs. verbal stimuli, which suggested that spatial skills are most developed during childhood and adolescence, while verbal attentional skills tend to peak in adulthood. Factor analysis and family transmission patterns further suggested that the two types of attention (spatial and verbal) were independent and that each was heritable to some degree. Experimental distraction did not disrupt performance in any of the subjects and, in fact, tended to improve it in the adolescents, especially for sparial stimuli. We conclude that the CPT-IP is appropriate for use with families containing members differing widely in age and processing skills.
