Using an oral sentence production task, we investigated how preschoolers (N = 28) produce agreement with complex noun phrases and compared their performance to college students (N = 32) to determine whether preschoolers produce agreement patterns that are qualitatively similar to adults'.

Differences in articulation error rates and error patterns as a function of five elicitation modes (picture, picture with pretraining, word repetition, sentence repetition, and nonsense word repetition) were examined.

When the more distant object was larger but subtended a smaller visual angle than the nearer, subjects tended to base judgments on retinal size. Motion paralax information increased accuracy of judgments of…
