To test between two recent accounts of the early stages in the acquisition of negation, we conducted an elicited production study with 25 children, between 2;05 and 3;04 (mean 2;11). The experimental study produced a robust set of negative sentences, with considerable individual variation. Although 13 of the child participants mainly produced…

This study examined lexical-phonological interactions in the first 50 words of a group of monolingual German- and Spanish-speaking children and bilingual German--Spanish children. The phonological characteristics of the earliest target word forms and output patterns of these children were analyzed to determine whether bilingual children select…

Infants across cultures need to identify the characteristics of their native languages in order to become competent speakers. The means by which Spanish-speaking children learn to produce number-gender linguistic markers has not been sufficiently investigated. Thirty-eight three-year-olds were tested in Berko-like production tasks, in which they…

In French, the acquisition of object clitics seems delayed, and omissions are documented. In this article, we look at the experimental paradigm traditionally used to elicit object clitics and propose a new elicitation procedure that is closer to how clitics are produced in spontaneous production. We show that under the proposed new experiment, the…

Stoel-Gammon (this issue) provides a welcome addition to the phonological acquisition literature, bringing together insights from long-standing and more recent research to address the relationship between the developing phonological system and the developing lexicon. A growing literature on children's early use of words across languages and…

In previous studies of phonological sensitivity, toddlers have failed to differentiate mispronunciations of varying severity. We provide evidence of more sophisticated phonological knowledge. Nineteen-month-olds were presented with displays consisting of one familiar and one unfamiliar object. In Experiment 1, names of familiar objects were…

Consonant mastery is one of the most widely used metrics of typical phonological acquisition and of phonological disorder. Two fundamental methodological questions concerning research on consonant acquisition are (1) how to elicit a representative sample of productions and (2) how to analyse this sample once it has been collected. This paper…

A case study of a 2-year-old progressing normally in speech development provides evidence of suprasegmental marking of the plural, thought to be adopted only in language-impaired children. Acoustic analyses of the durations and intensity of elicited words indicate that the child had adopted a suprasegmental strategy for marking the singular/plural…

In this study, phonological similarity neighborhood sizes were calculated for expressive lexicon derived from 2 vocabulary lists representative of children aged 1;3 to 3;0. Over 80% of the words in these early lexicons had at least one phonological neighbor; nearly 20% had six or more phonological neighbors. (Contains 29 references.)

The phonological rhythm of French is characterized by a tendency to syllabic isochrony within an utterance and a clear final lengthening, whereas the rhythm of English is stress-timed. A study of babbling at a turning period of the child's development has shown that the French child acquires adult phonological rhythm quite early in interactive…

The claim that multiple-birth children use "twin language" was investigated by describing and comparing the phonological characteristics of the speech of 19 sets of multiple birth children (aged 2-4) and by measuring multiple-birth children's understanding of their twins' or triplets' context-free speech. Results indicated that multiple…

A blind child and her sighted twin sister were recorded at home once a month from 2;5 to 3;5, and their repetitions and routines were analyzed with respect to three dimensions. Results showed that the blind twin used routines and modified imitations and repetitions more frequently, and her use of modified repetitions increased during the study.…

The lexical variables of word frequency and neighborhood density were hypothesized to facilitate sound change to varying degrees. Twelve children with functional phonological delays participated in an alternating-treatments experiment to promote sound change. Results indicated word frequency was most facilitative in sound change, whereas dense…

This study examined adult and child word-initial voice onset time productions in English and Hindi to determine the age of acquisition of the phonemic voice contrast. Cross-linguistic differences in patterns of acquisition were found, but these were not necessarily traced to the different phonological systems. (JL)
