Toddlers with smaller vocabulary than expected for their age are considered late talkers (LT). This study explored the effects of characteristics of words on vocabulary acquisition of 12- to 24-month-old LT children compared with an age matched (AM) and a vocabulary matched (VM) group of typically developing peers. Using the…

Beginning with the classic work of Shepard, Hovland, & Jenkins (1961), Type II visual patterns (e.g., exemplars are large white squares OR small black triangles) have held a special place in investigations of human learning. Recent research on Type II "linguistic" patterns has shown that they are relatively frequent across languages…

In learning language, children must discover how to interpret the linguistic significance of phonetic variation. On some accounts, receptive phonology is grounded in perceptual learning of phonetic categories from phonetic distributions drawn over the infant's sample of speech. On other accounts, receptive phonology is instead based on phonetic…

Studies on the acquisition of Spanish as a first language do not agree on the patterns and factors relevant for coda development. In order to shed light on the questions involved, a longitudinal study of coda development in Northern European Spanish was carried out to explore the relationship between accuracy, markedness and frequency. The study…

Cross-linguistically, languages allow a wider variety of phonotactic patterns in onsets than in codas. However, the variability of phonotactic patterns in coda position in different languages suggests these patterns must, at least in part, be learned. Two experiments were conducted to explore whether there is an asymmetry in English-learning…

Adult learners know that language is for communicating and that there are patterns in the language that need to be learned. This affects the way they engage with language input; they search for form-meaning linkages, and this effortful engagement could interfere with their learning, especially for things like grammatical gender that often have at…

To understand the interactions between production patterns common to children regardless of language environment and the early appearance of production effects based on perceptual learning from the ambient language requires the study of languages with diverse phonological properties. Few studies have evaluated early phonological acquisition…

In this study, we examined the nature of infants' representations of newly encountered word forms. Using a word-object association task, we taught 14-month-olds novel three-syllable words differing in segments and stress patterns. At test, we manipulated the stress pattern of the word or the position of the stressed syllable in the word. Our…

During the first year of life, infants begin to have difficulties perceiving non-native vowel and consonant contrasts, thus adapting their perception to the phonetic categories of the target language. In this paper, we examine the perception of a non-segmental feature, i.e. stress. Previous research with adults has shown that speakers of French (a…

This study explored the sensitivity of 20 10- to 11-month-old infants to the phonological characteristics of their native language. Tone-probe event-related potentials were obtained for subjects listening to a story, either with normal English function morphemes or modified with atypical function morphemes. Results suggest that the 11-month-olds,…

Considers the possibility that infants from different linguistic backgrounds babble similarly. Results of an experiment show that Spanish- and English-learning babies produce predominantly CV syllables with voiceless, unaspirated plosive consonants. Vowel production is also similar. (EKN)

Analyzes a child's use of word-level phonological constraints in multi-word utterances. The selection and avoidance patterns and modifications of adult forms indicated the presence of a syllable sequencing constraint that governed grammar and word combinations. (Author/CB)

Presents a case study of the babbling monologues produced by a Dutch child in the six weeks following acquisiton of the first word, which shows that this child's word production and his concurrent babbling are very much related. Concludes that word production influences the course of babbling and vice versa. (SED)

Examines onset, atrophy, and possible interaction of a set of patterns in the speech of a child acquiring French and English. Examines how data bear on the question of whether the bilingual child has two distinct production phonologies from the earliest stage. Tests recent claims consonant harmony patterns. (Author/VWL)

Previous research has shown that infants begin to display sensitivities to language-specific phonotactics and probabilistic phonotactics at around 9 months of age. However, certain phonotactic patterns have not yet been examined, such as contrast neutralization, in which phonemic contrasts are neutralized typically in syllable- or word-final…
