Responds to Gordon's critique (in this issue) of Bohannon and Stanowicz (1988) by pointing out relevant and irrelevant aspects of discussions of learnability. Rates of feedback found in Bohannon and Stanowicz are shown to be sufficient to spur learning in many species. Evidence against the universality of negative evidence is discounted. (RH)

Critiques models of children's acquisition of the English past tense. Discusses the sequence of language development in a child and as predicted by a model, the purported U-shaped sequence of the development of children's past-tense usage, and children's overregularization and irregularization errors in past-tense usage. (BC)

Two experiments presented infants with artificial language input in which at least two generalizations were logically possible. The results demonstrate that infants made one of the two generalizations tested, the one that was most statistically consistent with the particular subset of the data they received. The experiments shed light on how…

Little is known about language development in school-age children in Asian countries. This research reports on 3 measures of language development in 100 Cantonese-speaking children age 5 to 9 years. Word scores, structure scores, and the mean length of communication units (MLCU) were derived from a story-retelling task. The structure score was…

In the "blocking-and-retrieval-failure" account of overregularization (OR; G. F. Marcus, 1995; G. F. Marcus et al., 1992), the claim that a symbolic rule generates regular inflection is founded on pervasively low past tense OR rates and the lack of a substantive difference between past tense and plural OR rates. Evidence of extended periods of OR…

This study utilized an electronic data linkage method to examine the effects of risk factors present at birth on language development in preschool. The Preschool Language Scale-3 (PLS-3) was administered to 853 low-income children, and cumulative risk data were abstracted from linked birth records. At least one risk factor was present in 94% of…

The spontaneous language sample forms an important part of the language evaluation protocol (M. Dunn, J. Flax, M. Sliwinski, & D. Aram, 1996; J. L. Evans & H. K. Craig, 1992; L. E. Evans & J. Miller, 1999) because of the limitations of standardized language tests and their unavailability in certain languages, such as Afrikaans. This study examined…

Two studies investigated how preschool children's interpretations of novel words as names for parts of objects were affected by 3 kinds of information: (a) whole object familiarity, (b) whole part juxtaposition, and (c) syntactic information indicating possession. Study 1 tested 3- to 4-year-olds and found that although there was evidence that all…

Truscott and Sharwood-Smith's (henceforth T&SS's) paper offers an interesting set of hypotheses about one possible processing perspective in research on language acquisition. What is striking about this exposition of their model is that it ignores almost entirely the context of previous research on this issue. Embedding their exposition in its…

A critical question about early word learning is whether word learning constraints such as mutual exclusivity exist and foster early language acquisition. It is well established that children will map a novel label to a novel rather than a familiar object. Evidence for the role of mutual exclusivity in such indirect word learning has been…

This paper attempts to address the issue of language development in hearing impaired children. It argues that interpreters, teachers or peers can provide deaf children with language exposure so that they can acquire their native languages more easily. It also argues that the provision of a developmentally appropriate print-rich environments is the…

Prelinguistic Milieu Teaching (PMT) is an intervention designed to teach young children to initiate nonverbal communication using vocalizations, gestures, and eye-gaze. Children are taught through social routines in their natural environment. Techniques include contriving an environment in which the children will be motivated to communicate and…

Purpose: Personal narratives are common in children's conversations, recommended as the appropriate genre for early writing by educators, and part of many high-stakes tests, possibly because they tend to be better formed than fictional narratives. However, current practice in the field of speech-language pathology employs fictional narratives in…

This study reports on a comparison of the use and knowledge of tense-marking morphemes in English by first language (L1), second language (L2), and specific language impairment (SLI) children. The objective of our research was to ascertain whether the L2 children's tense acquisition patterns were similar or dissimilar to those of the L1 and SLI…

Hartshorne and Ullman (2006 ) presented naturalistic language data from 25 children (15 boys, 10 girls) and showed that girls produced more past tense overregularization errors than did boys. In particular, girls were more likely to overregularize irregular verbs whose stems share phonological similarities with regular verbs. It was argued that…
