The content of 228 college student's writing samples appears to be a main determiner of how many and what types of preposition errors will appear. These results indicate that preposition errors point to cognitive lags and complex, abstract writing tasks may be the appropriate treatment. (Author/PN)

Adult and child L2 acquisition of syntax-semantics interface phenomena must be compared with monolingual L1 acquisition of the same phenomena in order to assess the possible effects of interference and transfer. However, this "L1A touchstone" can also be misleading because non-grammatical mechanisms that interact with such interface phenomena may…

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…

This study proposes that children's phonological behavior at Stage VI of sensorimotor development may show markedly decreased variability compared to children at Stage V. According to Piaget, sensorimotor development during Stage VI is distinguished from preceding stages by the onset of representational ability and ability to form mental…

A theory of how people learn certain procedural skills is presented. It is based on the idea that the teaching and learning that goes on in a classroom is like an ordinary conversation. The speaker (teacher) compresses a non-linear knowledge structure (the target procedure) into a linear sequence of utterances (lessons). The listener (student)…

The purpose of this research was to develop methods to study the effects of context on children's comprehension and production of temporal terms such as "before,""after,""next,""then," and "but first." A longitudinal study, using naturalistic and traditional laboratory methods, and three…
