The study used naturalistic data on the production of nominal prefixes in the Otopamean language Northern Pame (autonym: Xi'iuy) to test Whole Word (constructivist) and Minimal Word (prosodic) theories for the acquisition of inflection. Whole Word theories assume that children store words in their entirety; Minimal Word theories assume that…

The organization of our knowledge about the world into an interconnected network of concepts linked by relations profoundly impacts many facets of cognition, including attention, memory retrieval, reasoning, and learning. It is therefore crucial to understand how organized semantic representations are acquired. The present experiment investigated…

The comprehension of paired wh-questions is examined in child Mandarin, to compare the age of acquisition with that of children speaking European languages like English and German. In Study 1, participants were 734 Mandarin speakers aged 2;6-7;11, drawn from four regions of China. Results reveal a striking parallel between the acquisition of…

This dissertation explores parallels between Complementizer Phrase (CP) and Determiner Phrase (DP) semantics, syntax, and morphology--including similarities in case-assignment, subject-verb and possessor-possessum agreement, subject and possessor semantics, and overall syntactic structure--in first language acquisition. Applying theoretical…

Stoel-Gammon (this issue) highlights the close and symbiotic association that exists between the lexical and phonological domains in early linguistic development. Her comprehensive review considers two bodies of literature: (1) child-centred studies; and (2) studies based on adult psycholinguistic research. Within the child-centred studies, both…

The relation of social and linguistic input measures to early vocabulary development was examined in 30 low-income African American mother-infant pairs. Observations were conducted when the child was 0 years, 1 month (0;1), 0;4, 0;8, 1;0, 1;6, and 2;0. Maternal input was coded for word types and tokens, contingent responsiveness, and…

This study explored the relationships between several aspects of maternal language and measures of the psycholinguistic abilities of 26 Mexican-American mothers and their children enrolled in Head Start. Several significant relationships were obtained including a significant correlation between mothers' and childrens' total language scores.…

Thirty-one eight-year-old boys were the subjects of a study to determine the relationship between language skills in infancy and reading skills at elementary school age. As infants, the boys had been taped in interaction sessions with their mothers. The level of skill development of the infants was measured according to the principles of…

Language acquisition in children, ages 6 to 10 years, and their linguistic competence with respect to complex aspects of English syntax, are studied. The nature of specific disparities between adult and child grammar are discussed, and the gradual reduction of these disparities as the children's knowledge of language increases is traced. In all,…

Interviews with 108 Navajo children from bilingual first grade classes on Navajo reservations were recorded. Analysis of the interviews focused on phonological, grammatical, and lexical features that show a systematic variation within the speech of individuals or between individuals. Variable features were compared with background factors such as…
