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…

The study aims to account for the distribution of finite versus non-finite verbs during a developmental period when children use both types of verb forms in contexts requiring finiteness. To meet this goal, longitudinal samples from three Hebrew-acquiring children (aged 1;4-2;6) are examined from the onset of verb production and across the…

This study compared segmental distribution patterns for consonants and vowels in English infant-directed speech (IDS) and adult-directed speech (ADS). A previous study of Korean indicated that segmental patterns of IDS differed from ADS patterns (Lee, Davis & MacNeilage, 2008). The aim of the current study was to determine whether such differences…

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)

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)

Describes a study of adult listeners' perceptions of infant babbling. Adult judges were unable to identify language background significantly above chance level. Findings do not support the babbling drift hypothesis which predicts that babbling begins to approximate characteristics of the mother tongue as infants approach meaningful speech. (SED)

Argues that knowing how infants process speech is a prerequisite to any definition of linguistic experience and therefore, the discrimination paradigm does not provide a test for the effect of experience on infants' speech discrimination. Outlines conditions to be met in order to conclude an effect of experience. (EKN)

Examines the process of language acquisition as well as scientists' understanding of the intricate process of learning to talk. Specifically addresses: (1) foundations of language; (2) prenatal period; (3) first month after birth; and (4) conversation. Also discusses adult-child activities that stimulate language-learning. (SD)

This monograph presents a descriptive analysis of the syntactic patterns in 16 corpora of word combinations from 11 infants learning either English (six children), Samoan, Finnish, Hebrew, or Swedish. The mean utterance lengths range up to about 1.7 morpehmes. There are both reanalyses of corpora in the literature and new corpora. The data…

Examines the phonetic patterns and linguistic development of an infant who was tracheostomized during the period that infants normally begin to produce syllabic vocalization. It was found that the infant had developed only a tenth of the canonical syllables expected in normally developing infants, a small inventory of consonant-like segments, and…

This study reports a replication of an earlier study by Kilbourne and Ginsberg (1980) which indicated the occurrence of a transition from predominantly coacting to predominantly alternating infant-mother vocalization patterns. In addition, the present study examined the modulating influences of nursing activity and mother's focus of attention upon…

Examines issues relating to similarity neighborhoods of words in children's lexicons. Young children's receptive vocabularies were analyzed for three-phoneme, four-phoneme and five-phoneme words. The pattern of the original results from Charles-Luce & Luce (1990) was replicated. (18 references) (Author/CK)

Video-analysis was used to investigate the transition from coacting to alternating patterns of infant-mother vocalizations in this longitudinal study of one infant. In addition to investigating the transition and its developmental implications, the relationship between the temporal patterning of kinesic and vocal behaviors was studied. The study…

Reports results of a longitudinal study of the acquisition of first words by 18 infants. Strategies used in word acquisition and environmental variables related to language development were investigated. Results were analyzed in terms of an interaction model of the language-learning process. (DP)

Followup to earlier report that focused on initial uses of first 10 words produced by 4 children is presented. Results of analysis of subsequent use of these 40 words is presented. Findings indicate that the role of linguistic input in early lexical development may decline sharply once a child has established initial uses for words. (24…
