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…

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…

Bilingual and monolingual children were presented with experimental conditions where response mode and semantic information was varied. Forty children, 20 in each language-type group, responded in the present progressive and the past tenses to a series of colored drawings of simple activities. Half of the subjects responded to the task under…

Investigators agree that mothers employ a variety of request forms and that children seem to be able to respond to these forms with a remarkable degree of accuracy. It is suggested that the speech of mothers to their children is filled with requests which are really not requests at all. It is shown that many of what appear to be adult requests to…

It is proposed that in studying the development of children's speech, the findings in the data are heavily influenced by what is expected to be found on the basis of our theoretical preconceptions. This phenomenon is actually more widespread than has previously been acknowledged, and our expectations about how children learn language may have to…

The interest of the psychologist in bilingualism from its origins in the early 1900's to the present is traced. Bilingualism and intelligence are discussed as well as some recent studies on bilingualism and cognitive development. Several areas where psychologists may provide valuable insights into the process of becoming bilingual are discussed…

Although educational psychologists are concerned with the acquisition of knowledge, particularly in the classroom, language acquisition and knowledge of language are areas slighted in their textbooks. Integration of developmental psycholinguistics into educational psychology courses should employ the recently emerging rationalist view rather than…

Several studies have begun to investigate the claim that children can make most phonological discriminations when they begin to speak. This paper investigates how well children aged 2;3 to 2;11 can discriminate between pairs of minimally different real words, and it shows that the results are affected by how well the children know the words. It is…
