The functional architecture of the verbal processing resource system was studied by testing aphasic patients in Canada and Boston for their abilities to use syntactic structure in sentence comprehension in isolation and under dual-task conditions. Results indicate that the processing resource system underlying syntactic processing is separate from…

A study explored working memory (WM) capacity, WM task requirements, as well as effects between WM, skills, knowledge base, and intelligence in adults with mental retardation and children aged 3-6 years. Adults were better on measures reflecting skills and knowledge base. Children performed better in phonological and visuo-spatial WM tasks.…

How do children determine the syntactic category of novel words? In this article we present the results of 2 experiments that investigated whether German children between 12 and 16 months of age can use distributional knowledge that determiners precede nouns and subject pronouns precede verbs to syntactically categorize adjacent novel words.…

This study used functional magnetic resonance imaging (fMRI) to examine brain-behavior correlations in a group of 16 children (9- to 12-year-olds). Activation was measured during a semantic judgment task presented in either the visual or auditory modality that required the individual to determine whether a final word was related in meaning to one…

Two studies examined the possibility of retrieval-induced forgetting by 7-year-olds. Children heard a story while viewing pictures of events mentioned in the story, each highlighting objects drawn from two distinct semantic categories (e.g. animals and food). Over the next several days, children were asked the same yes/no questions about half the…

This study investigates how different encoding strategies affect retention of Chinese characters (words) as measured by recall of the sound and meaning of the characters. Three types of encoding strategies were investigated during character learning: rote memorisation (shallow processing), student self-generated elaboration, and instructor-guided…

This study compared the effects of instructor-provided vs. learner-generated analyses of semantic relationships between major concepts on structural knowledge acquisition in an introductory psychology course. One group explained the relationships on instructor-provided graphic organizers; the other group classified relationships between concepts…

This review of the literature looks at writing disabilities in the context of special education services provided within regular classrooms. A definition of learning disabilities as well as a discussion of effects of left and right brain dominance and of the steps of the writing process begin the paper. Among the findings of the research synthesis…

A specific skill necessary to expand vocabulary is that of acquiring additional meanings for words that have common, already known meanings. A study was conducted to determine if presenting subjects with the known meaning of a word before requiring them to learn a new meaning for it would result in a learning detriment. The study used homonyms…

Limitations of the retrieval strategy dimension of Siegler's (1982, 1984) distributions-of-associations model of young children's estimation of sums are delineated, an alternative model is described, and findings of two studies designed to test key assumptions of the models are reported. In Study 1, kindergarten children with normal IQ and no…

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 "yes/no" method of vocabulary assessment requires students to indicate words they know from among a list of words and nonwords. Preliminary evidence gained from a study involving fifth grade students indicates that the method is superior in many ways to the multiple choice method of assessment. Analysis of "false alarms," cases in which…

Problems related to the structure of the mental lexicon are considered. The single access assumption, the passive memory assumption, and the heterogeneous memory assumption are rejected in favor of the theory which assumes several active memories, each able to store expression based on only one homogenous set of abstract primitives. One lexicon…

Overviews of schema theory, which focuses on the cognitive operations engaged in by the reader, and discourse analysis, which focuses on structural characteristics of the text itself, are presented in this paper. The first section explains the notion of cognitive schemata (patterns of expectations that are applied to incoming information) and…

This research discusses the probability of child witnesses providing a complete and accurate description of an event. Children have been regarded as particularly inaccurate, highly suggestible, and basically unreliable in court cases. Psychologists have concluded that younger children are much more suggestible than older children or adults, and a…
