The acquisition of systematic patterns and exceptions in different languages can be readily examined using the causative construction. Persian allows four types of causative structures, including one productive multiword structure (i.e. the light verb construction). In this study, we examine the development of all four structures in Persian child…

In this article we report two studies: a detailed longitudinal analysis of errors in "wh"-questions from six German-learning children (age 2 ; 0-3 ; 0) and an analysis of the prosodic characteristics of "wh"-questions in German child-directed speech. The results of the first study demonstrate that German-learning children…

Investigation of four- through six-year-olds' abilities to correct over-regularized plural nouns and verbs in the past tense showed that, generally, older children performed better than the younger children, and plural nouns were corrected significantly more than past-tense verb forms. Younger children were better at correcting the nouns than the…

Data from a transcript database of 12 children collected in 1-hour samples every month from 1;0 to 3;0 support the hypothesis that there should be strong differences in the frequency and types of errors between pronouns with suppletive nominatives and those without. The suppletive nominative forms "I" and "she" are blocked from overextension in a…

While children aged 1;10 and 2;1 show only a modest rate of mapping novel nouns onto unfamiliar rather than familiar objects, children aged 1;4 and 1;8 show a high rate. Two studies with young 2-year olds found the noun-mapping preference prevalent, but unless initial choices are strongly reinforced, increase in salience of familiar kinds lures…

Investigates the inconsistencies of personal pronoun production both in production and between production and comprehension in a pronoun-reversing child. (EKN)

Investigated whether the rate and patterns of pronoun case error were influenced by the composition of an individual pronoun's paradigm. Twenty-nine children ages 2;6 to 4;0 years were audiotaped interacting with their primary caregivers in various settings. Results indicated that 27 children produced case errors. The composition of a pronoun's…

Sentences evoked from three- to five-year-olds (N=16), analyzed for errors (particularly copying-without-deletion), showed errors when: the subject noun phrase (NP) contained a relative clause, the relative clause had an object gap, and the relative clause was long. (Author/CB)
