In Exp. I nouns were linked with verbs in paired-associate learning. Nouns were preceded by an article to induce a "sentence set." Grammatical number agreement was varied by inflecting either the noun or verb. ½ the Ss, 3rd, 5th, and 6th graders, and college students, learned a grammatical list, ½ an ungrammatical list. Grammatical lists were learned faster than ungrammatical lists by college Ss. In Exp. II ½ the noun-verb pairs were preceded by an article to induce a sentence set while ½ were not. ½ the pairs agreed in number. The pairs, making 4 conditions, were presented on sound tape to 1st and 2nd graders and college Ss. Grammatical pairs were learned faster at both age levels. Sentence set had no effect on grammatical pairs, but when combined with ungrammatical pairs the sentence set interfered with learning by college Ss but not by grade school Ss.
