幼儿的组合能力以年龄（20个月和27个月）和任务要求（对成分的熟悉程度、组合的长度、组合的复杂性、行动的中心/非中心焦点、行为领域）为函数，在几个行为领域进行了测试。表示了6个特定的域。在4个领域（对象游戏、伪装、社交游戏、运动游戏）的诱导模仿和另外2个领域（语言和同伴导向的社交提议）的自发模仿中观察到儿童的组合。与年幼的孩子相比，年龄较大的孩子在每个领域（包括同伴互动）产生了更多至少2或3种离散行为的组合，而非组合行为则较少。在产生组合的各个领域中也发现了一致的关系，也就是说，在一个领域中产生更多组合的孩子在其他领域也会产生更多组合。最后，5个被操纵的任务需求中有4个被证明会影响性能。结果讨论了可能的年龄相关的限制组合技能，在一般，跨领域水平在幼儿期操作。
Toddlers' combinatorial abilities were examined over several behavioral domains as a function of age (20 and 27 months) and task demands (familiarity of components, length of combinations, complexity of combinations, centered/decentered focus of action, behavioral domain). 6 specific domains were represented. Children's combinations were observed during elicited imitation in 4 of the domains (object play, pretense, social play, motor play) and spontaneous production in 2 others (language and peer-directed social overtures). Relative to younger children, older children produced more combinations of at least 2 or 3 discrete behaviors in every domain, including peer interaction, and fewer noncombinatorial behaviors. Consistent relations were also found across domains for production of combinations, that is, children who produced more combinations in one domain also did so in others. Finally, 4 of the 5 manipulated task demands proved to affect performance. Results are discussed in terms of possible age-related constraints on combinatorial skills that operate at a general, cross-domain level during toddlerhood.
