Catarina Vales; Patience Stevens; Anna V. Fisher – Grantee Submission, 2020
Organized semantic representations encoding across- and within-domain distinctions are a hallmark of mature cognition, and understanding how they change with experience and learning is a key endeavor in developmental science. Existing computational modeling studies provide a mechanistic framework for understanding how structured semantic…

Morse, Anthony F.; Cangelosi, Angelo – Cognitive Science, 2017
Most theories of learning would predict a gradual acquisition and refinement of skills as learning progresses, and while some highlight exponential growth, this fails to explain why natural cognitive development typically progresses in stages. Models that do span multiple developmental stages typically have parameters to "switch" between…

Ganger, Jennifer; Brent, Michael R. – Developmental Psychology, 2004
The authors asked whether there is evidence to support the existence of the vocabulary spurt, an increase in the rate of word learning that is thought to occur during the 2nd year of life. Using longitudinal data from 38 children, they modeled the rate of word learning with two functions, one with an inflection point (logistic), which would…

Snyder, Lynn S.; And Others – Journal of Child Language, 1981
Presents a study of the early vocabulary of young children, considering variables such as contextual flexibility, content, and composition of the lexicon in comprehension and production. Reports evidence for a relative independence between these two domains, and for an early version of the referential style observed at later stages of development.…

Chapman, Kathy; And Others – Journal of Speech and Hearing Disorders, 1983
The frequency and type of inappropriate word extensions (i.e., use of ball for moon) in the spontaneous speech of nine young language disordered children (2.8 to 3.4 years old) were studied. The percentage of inappropriate word extensions of these children was comparable to that of normal children at the same level of linguistic development.…

Miscione, John L.; And Others – 1977
This study investigated preschool children's understanding of the words "know" and "guess." Subjects for the study were 48 male and female preschool children ranging in age from 3.6 to 6.6 years. The children were divided into three age groups representing one year intervals. The task for the study involved a "guessing" game in which a colored…

Durand, C. – International Journal of Early Childhood, 1997
Summarizes progressions between 2 and 6 years of age in children's power of concentration, ability to express ideas, build logical relationships, structure spoken words, and play with the semantic, phonetic, syntactical, and morphological aspects of oral language. Notes that the progression depends on the educator's interaction with the child.…

Klausmeier, Herbert J.; And Others – 1976
The Conceptual Learning and Development (CLD) Model specifies four levels of concept attainment (concrete, identity, classificatory, and formal) and three uses of concepts (problem solving, subordinate-supraordinate, and principles). Longitudinal and cross-sectional studies of concept attainment may be conducted. The results of this study of 300…
