Without criteria for what counts as a U/N-shaped developmental trajectory, it is not clear how many legitimate "Us" really exist. Many, if not all, "Us" may turn out to be illusions borne out of our sampling methods, task construal, and blurry lenses of description. (Contains 2 figures.)

Distributional information is a potential cue for learning syntactic categories. Recent studies demonstrate a developmental trajectory in the level of abstraction of distributional learning in young infants. Here we investigate the effect of prosody on infants' learning of adjacent relations between words. Twelve- to thirteen-month-old infants…

Children from 18-30 months who spoke in either one-or two-word utterances were tested for their ability to discriminate between grammatical and ungrammatical sentences. Results showed that these children can discriminate. (ST)

This study examined the relationship between syntax discrimination and other language skills with 50 children each in kindergarten, first grade and second grade. Also, the children were asked to imitate and show comprehension of normal and scrambled grammar sentences. (Author/JH)

This study examined the effects of sentence length and correct syntax on sentence imitation in 54 first-, second-, and fifth-grade elementary school children. The same children were asked to perform an additional discrimination task between normal and scrambled sentences. (Author/CS)

Utilizing careful, empirical definitions of lesson kinetic structure, the authors tested two hypotheses: student content achievement is directly related to lesson content structure; and, awareness of commonality and theme development is directly related to lesson content structure. Student achievement seems to be related to communication…

Language training for the non-verbal or language delayed child should utilize feedback to reinforce correct responses and should closely follow the syntactical development of normal children. The two basic areas of language training are receptive and expressive. Receptive language training includes attending and responding, following single phase…

This study examines some variables that may affect two aspects of syntax in Head Start children; the use of descriptors and the use of complete sentences. Thirty-six children were assigned to six experimental conditions in a design which varied adult verbal modeling, feedback, and sex. Children given adult verbal modeling produced significantly…

This paper examines the perceptual processes that underlie normal language acquisition with relation to perceptual dysfunctions in the aphasic child. Experiments are cited which seem to indicate that auditory dyfunctions may underlie language impairment. Experimental studies of the linguistic systems of the aphasic child seem to support the theory…

One of the most important capacities which children employ when learning language is the capacity to generalize. A child who hears an utterance of a verbal expression while perceiving a particular object (or action, aspect, etc.) becomes normally able to apply the expression not only to this object but also to all those objects which, for him, are…
