使用来自10个学区的接受特殊教育服务的学生的纵向WISC、WISC-R和WISC-III记录，研究了当产生膨胀分数的老化规范被新规范取代时，IQ中的溜溜球趋势中的年龄差异。描述性和个体生长模型分析显示，虽然智商的长期模式没有随着时间的推移而改变，但年龄在这种模式中的作用却发生了变化。具体来说，在早期测试中，当新规范取代旧规范时，年龄较大的儿童的测试分数下降幅度较小。然而，这些差异在目前的测试中消失了。结果表明，智商和年龄之间的关系是复杂的，并进一步显示了使用个人成长模型来揭示纵向数据中的模式的好处，否则会被更传统的分析技术所掩盖。(c)2005年由Elsevier Inc.出版
Age differences within the yo-yo trend in IQ, caused when aging norms that produce inflated scores are replaced with new norms, were examined using longitudinal WISC, WISC-R and WISC-III records of students tested for special education services from 10 school districts. Descriptive and individual growth modeling analyses revealed that while the secular pattern in IQ has not changed over time, the role of age within this pattern has. Specifically, the decline in test scores that occurs when new norms replace older ones was smaller for older children in earlier testings. These differences, however, disappeared in more current testings. The results reveal that the relationship between IQ and age is complex and, further, shows the benefits of using individual growth modeling to uncover patterns within longitudinal data that would otherwise be obscured with more traditional analytic techniques.
