In natural language, evidence suggests that, while some rules are productive (regular), applying broadly to new words, others are restricted to a specific set of lexical items (irregular). Further, the literature suggests that children make a categorical distinction between regular and irregular rules, applying only regular rules productively…

While normal child language acquisition results in complete productive and comprehension abilities at a relatively young age, adult language acquisition is more belabored and often results in linguistic abilities that differ from those of native speakers in terms of both productive and comprehension abilities. A major line of research in language…

Bilinguals must have a mechanism for controlling attention to their two language systems in order to achieve fluent performance in each language without intrusions from the other. This paper examines the evidence that the experience of controlling attention to two languages boosts the development of executive control processes in childhood for…

Contrary to earlier assertions, young children do not interpret the word "different" to mean "same." Both two-and-a-half year old children and adults interpret requests for same or different objects appropriately, apparently following conventions of conversational discourse. These data offer no support for a discrete semantic feature model of…

Investigates the influence of word meaning on lexical processing in children and adults. Examines developmental trends in lexical decisions for abstract and concrete words. Concludes that word meaning influences lexical processing in children but that there is a developmental shift in the kinds of semantic characteristics that are available for…

After presenting a brief description of the principles of a story grammar, some experimental results are summarized to illustrate the power of story schemata in controlling recall. Specially constructed versions of four stories were used with second, fourth, and sixth graders and in a second experiment with adults. One version of each story was…

Three experiments used a visual fixation technique to examine whether toddlers interpret speech continuously. Found that 24-month-olds had delayed responses when a competing distractor picture's label overlapped phonetically with the target at onset, but not when the pictures' labels rhymed, showing that children monitored speech stream…

The assumption that "ideal" text grammars are valid descriptions of the schemata used by children to organize their recall of text was challenged in a study involving 150 elementary school children. The children, all with above-average reading ability, were classified as having one of three types of schemata: theme-initial (identifying…

Aspects of the processing of frequency information were investigated in two studies. The first showed that second graders were as prepared to process frequency differences as adults. The second showed that practice at frequency counting does not improve the performance of young adults and neither does feedback regarding earlier performance.…

Three experiments conducted with normal adults in both Israel and the United States show that the answers people give to questions vary with the category of the target and its distance. (FL)

Reports on 5 experiments investigating the effect of blocking words according to semantic category on ordered recall in adults and young children. (Author/RM)

This article considers the implications of two central constructs of sociocultural theory (SCT) for second language (L2) development: mediation and internalization. It first discusses Vygotsky's general theoretical claim that human mental activity arises as a consequence of the functional system formed by our biologically specified mental…

Relational-inference, a process associated with developmental change in performance on classification items, was investigated in two experiments. The accuracy and latency with which 20 subjects at each of 3 age levels (8, 11, and adult) stated relationships among concepts were tested. In experiment 1, 40 triplets of concepts related by a class…
