Two related experiments examined generalization across contexts involving different sentence forms when selected grammatical features were trained within a single syntactic context. Results obtained within a single-subject multiple baseline design showed that training the verbal/auxiliary (contracted with pronoun he) was sufficient to induce its generalization across a variety of verbs, object noun phrases, and a different subjective case pronoun, but not across an objective case pronoun. Similar results were obtained for the uncontractible auxiliary in the past tense. Generalization of the uncontractible auxiliary in the present tense was noted across different verbs; so also was the generalization of contractible copula to different adjectives qualifying the subjective case pronouns he and she (but not in qualifying an objective case pronoun it). Finally, generalization of possessive s inflection across male, female, and animal categories was evident. Trained behavior generalized to home situation in one of the experiments. Some unexpected results also suggest that training on certain forms of either verbal auxiliary or copula may be sufficient to generate correct production of both of them.
两项相关实验考察了在单一句法语境中训练特定语法特征时，跨不同句子形式语境的泛化情况。在单被试多基线设计中获得的结果表明，训练动词/助动词（与代词he缩写）足以使其在各种动词、宾语名词短语以及不同主格代词中泛化，但在宾格代词中则不会泛化。对于过去时态中不可缩写的助动词也得到了类似结果。现在时态中不可缩写助动词在不同动词间的泛化得到了证实；可缩写系动词在修饰主格代词he和she的不同形容词间的泛化情况也是如此（但修饰宾格代词it时则不会泛化）。最后，所有格s屈折变化在男性、女性和动物类别间的泛化很明显。在其中一项实验中，经过训练的行为泛化到了家庭情境。一些意外结果还表明，对动词助动词或系动词的某些形式进行训练可能足以促使两者都能正确产出。
