The similar-sequence and the similar-structure hypotheses are the two mainstays of the developmental approach to mental retardation. In the present study, a third way, the similar-trajectory hypothesis, is described and illustrated using the WAIS-R results of adults with and without mental retardation aged from 20 to 54 years. The whole sample (N=633) comprised 306 participants with mental retardation and 327 without mental retardation. Hierarchical regression analyses comparing the two groups showed similar evolutions of scores with increasing age for verbal and performance scales. These results seem to validate the similar-trajectory hypothesis, at least for the present samples and for the aspects of cognitive development considered here. Some weaknesses and implications of the study are considered in the discussion.
相似序列假说和相似结构假说是智力发育迟缓发展研究方法的两大支柱。在本研究中，描述了第三种方法，即相似轨迹假说，并使用20至54岁有和没有智力发育迟缓的成年人的韦氏成人智力量表修订版（WAIS-R）结果进行了说明。整个样本（N = 633）包括306名智力发育迟缓参与者和327名无智力发育迟缓参与者。比较两组的分层回归分析表明，随着年龄增长，言语和操作量表的分数有相似的变化趋势。这些结果似乎验证了相似轨迹假说，至少对于目前的样本以及此处所考虑的认知发展方面是如此。讨论中考虑了该研究的一些不足之处及启示。
