来自两个不同实验室的研究测试了严重精神发育迟滞和最小语言能力的个体的等效类。在第一项研究中，3名被试学习了几种匹配样本的行为：将图片比较刺激与听写单词样本刺激（AB）匹配，将相同的图片与印刷字母样本（CB）匹配，以及将图片与非代表性形式（DB）匹配。在随后的测试中，所有个体都立即显示出涌现关系AC、AD、BC、艾德、CD和DC，共同构成了等效性的积极证明（如Sidman所定义的）。第二项研究获得了积极的等效性测试结果，在1/2的个人同样最小的口头剧目。总而言之，这些研究质疑以前的断言，等价类是证明只有在个人发展良好的语言剧目。
Studies from two different laboratories tested for equivalence classes in individuals with severe mental retardation and minimal verbal repertoires. in the first study, 3 individuals learned several matching-to-sample performances: matching picture comparison stimuli to dictated-word sample stimuli (AB), matching those same pictures to printed letter samples (CB), and also matching the pictures to nonrepresentative forms (DB). On subsequent tests, all individuals immediately displayed Emergent Relations AC, AD, BC, ED, CD, and DC, together constituting a positive demonstration of equivalence (as defined by Sidman). The second study obtained a positive equivalence test outcome in 1 of 2 individuals with similarly minimal verbal repertoires. Taken together, these studies call into question previous assertions that equivalence classes are demonstrable only in individuals with well-developed language repertoires.
