Selected aspects of early phonological development are described, and eight important characteristics are suggested. It is held that the child plays a highly active, creative role in the acquisition process. The child's early vocables constitute a connecting link between babbling and adult-modeled speech; the child's phonological systems for…

A study was conducted to determine whether the child expresses linguistic knowledge during the single-word period. The order of mention in 65 sets of successive single-word utterances from five children at Stage 1, two to four years old, were analyzed. To elicit speech, the children were shown line drawings representing such situations as animate…

Examines the hypothesis that adults and children have media-specific conceptions of picturing and that the functional uses of photography and drawing differ across development. Results showed an age progression from viewing photography as only reflecting the real object to viewing it as a medium that allows for control and alteration of reality.…

Data are presented from one subject (J) that show a gradual development of the complexity of words in terms of syllable structure and degree of phonetic similarity of co-occurring consonants. During the age range of 1;9 to 2;6, J's data show a highly systematic progression of stages, each characterized by fewer restrictions on the number, order,…

The research reported here was carried out to help establish the normal course of fricative acquisition as a basis for comparisons with abnormal development. Three questions concerning phonological processes were investigated as part of a larger study of fricative acquisition: (1) the phonological processes that underlie children's fricative…

A question of both theoretical and practical importance for the study of phonological development is whether there is a difference in the status of productions rendered spontaneously by the child and those repeated by the child after either an adult model or his own production. The relevant theoretical questions are: (1) Are all the child's…

Comprehension of the quantifiers "some" and "all" was studied with 202 children, three to nine years old. Thirty-two quantifier sentences dealing with descriptions of circles and squares were presented to the children. Wooden objects were presented to some children to see if results were affected by the choice of abstract objects, but no…

A study was conducted to determine whether children give evidence of using any of six comprehension strategies and whether children of same and different ages use different strategies. It was studied how comprehension performance can best be predicted by other facts about the child, including his language and his language input. The six…

This paper reports the results of a preliminary study dealing with the ways in which children between ages 6 and 7 organize spoken language. In particular, aspects of the temporal and segmental structure of polysyllabic English words containing the syllable C/jul/, as in the word "pediculous," are dealt with. This study is based on the assumption…

The crib talk reported here of a 2;2-2;4-year-old boy replicates the phenomenon of crib talk reported in previous studies by other investigators. This study adds a corpus of mother-child interaction (MCI) and tests one aspect of the hypothesis that crib talk may enhance production of linguistic forms at a later date. Transcripts of monologues were…

Comprehension of reversible active and passive sentences was studied with 48 Japanese children between the ages of two and six. Four types of sentences were constructed using passive and active structures and two word orders: subject-object-verb (SOV) and object-subject-verb (OSV). The basic order of elements in a simple sentence in Japanese is…

By age two, a child begins to form complex sentences by joining two or more sentences or by embedding one sentence into another. Formation of conjoined structures is a simpler process and emerges earlier than that of embedding structures. This paper attempts to answer the following questions: (1) Do children produce or understand embedding…

Children's early utterances were studied to determine whether there are developmental changes in the content, context, frequency, and form of their speech and the degree to which the changes correspond to changes in Piagetian cognitive stage. Twenty children were studied; six were 10 or 11 months old, and the remaining 14 were distributed evenly…

This paper reports on two aspects of dyadic communication skills: verbal imitation, and response to questions and commands, as they relate to the development of semantic functions in three English-speaking children. The children, aged 16, 21 and 22 months, were unobtrusively videotaped during weekly free play sessions with their mothers. The…

This paper reports on a longitudinal study of the acquisition of the voicing contrast in American-English work-initial stop consonants, as revealed through instrumental analysis of voice onset time characteristics. Four monolingual children were recorded at approximately two week intervals, beginning when the children were about 1;6. Data provide…
