Linguistics and Communication Disorders are considered two different disciplines by most students and scholars in both fields as well as by researchers working in other relevant fields such as psychology and education. However, most core disorders, disabilities and delays in communicative ability directly concern language, especially in…

Vygotsky's views on how language is instrumental in bringing about advanced forms of intellectual functioning offer a researchable framework from which to study this development. Developmentalists in psychology and linguistics have focused for too long on continuities rather than on the process of change in mental growth. The study of the…

The sensitive period as a developmental concept is discussed. Observations are made on various problems involved in attempting to explain adult difficulties with second language acquisition by invoking motivational and input factors. (Author/ NQ)

This review describes the prenatal and postnatal development of the human cortex. Neurogenesis, neuronal migration, dendrite maturation, synaptogenesis, and white matter development are discussed. In addition, the concept of "critical" or "sensitive" periods is discussed as well as genetic and environmental influences (Nature-Nurture). The effects…

How a child answers questions provides information about how he or she processes input. A child's early responses to questions at age one year, three months, were compared to her responses at one year, seven months, when she was in the two-word stage. (SW)

In studying the effects of different teaching methods on preschoolers' language abilities it was found that the productive training condition produced more generalized responding on other kinds of tasks. (Editor)

A study of 5-year olds' ability to distinguish promises from predictions was suspected to have achieved its results due to methodological problems. A similar study with 32 children ages 5 to 6 that used several variations of the previous study's procedures was found to have similar results, suggesting the earlier findings were an accurate…

Sixteen children (aged 14 to 26 months), who were reported by their parents to overextend, were tested for overextension in both language production and comprehension. The children were first asked to name each of a series of pictures of inappropriate exemplars of the words they were reported to overextend. Those words that were overextended, a…

Based on a study of 50 children between the ages of 3;0 and 5;6, the reasons for the differential difficulty of various forms of "who,""why,""when," and "how" questions are postulated. (EJS)

Examines the CDI-WORDS Short Form vocabulary checklist as an index of language production. The study focuses on the associations between this short form and directly observed measures of lexical production; the associations between short-form checklists administered at different ages; the predictive associations between short form scores and…

A study was conducted to test whether three, four, and five-year-old children would be better able to use either static or dynamic properties for grouping objects, and whether performance under these conditions would be better than when no property was given. One of the two study tasks, the free sort, also used by Rosch et al. (1976), asked…

Research evidence currently indicates that young children's communication skills for both the speaker and the listener roles are often ineffective. The accuracy of children's communication improves gradually over the elementary school years. Current thinking in the area of metacognition may be very useful in understanding the development of…

Three empirical studies were conducted to investigate the hypothesis that the "easy to see" construction (such as in the sentence "children are hard to understand") is acquired at a younger age than the 7-9 year range reported by previous studies (Cambon and Sinclair, 1974; Chomsky, 1969; 1972; Cromer, 1970; Kessel, 1970).…

The recent experimental literature on the acquisition of English antonyms is reviewed, with special reference to the position of Eve Clark and the particular ontogenetic assumptions her position entails. The assumptions examined are: (1) in a hierarchically organized lexical domain, the order of acquisition appears to be from the top of the…

This article hypothesizes that language repetition of young children (in the sense used by Kobashigawa and Snow) does not help language acquisition. The evidence comes from the results of a prior study in which no indication was found that mothers who repeat themselves a great deal have children who acquire language more quickly. However,…
