This study examined conceptual relationships in semantic memory using an indirect priming technique in high-functioning autistic adolescents and controls. The autistic subjects and controls showed similar semantic priming effects. However, correlations with nonverbal cognitive measures for the autistic subjects suggests that semantic processing in…

Eight commentaries are provided on an article examining the means by which bilinguals control their two language systems. (Author/VWL)

Replies to commentaries written by eight peers in response to an article the author wrote on the means by which bilinguals control their two language systems and in which he proposed an inhibitory control model that embodies the principle that there are multiple levels of control. (Author/VWL)

Presents the semantic information theory, formulated by the philosopher Fred Dretske, as a contribution to the discussion of metatheories and their practical implications in library and information science. Highlights include mathematical communication theory; digitization, perception, cognition, and concept formation; information and knowledge;…

A category effect (i.e., living vs. nonliving exemplars) in confrontation naming has been reported in association with various cerebral pathologies. However, the published reports conflict as to the presence of this category effect in normal controls. The present experiment included 90 subjects in three age groups (young, young-elderly, and…

Positron emission tomography was used to investigate two competing hypotheses about the role of the left inferior frontal gyrus (IFG) in word generation. One proposes a domain-specific organization, with neural activation dependent on the type of information being processed, i.e., surface sound structure or semantic. The other proposes a…

P. N. Johnson-Laird and R. M. J. Byrne proposed an influential theory of conditionals in which mental models represent logical possibilities and inferences are drawn from the extensions of possibilities that are used to represent conditionals. In this article, the authors argue that the extensional semantics underlying this theory is equivalent to…

In a recent study of conceptual combination, Estes (2003) presented evidence for the priming of relational information in the absence of shared constituents between the prime and target (e.g., "pancake spatula" was interpreted more quickly following "bacon tongs" than following "city riots"). He argued that these data support the view that…

Verbal fluency is a widely used neuropsychological paradigm. In fMRI implementations, conventional unpaced (self-paced) versions are suboptimal due to uncontrolled timing of responses, and overt responses carry the risk of motion artifact. We investigated the behavioral and neurofunctional effects of response pacing and overt speech in semantic…

The present study investigated the structure of categories and concepts in psychological research and the nature of mental representations in general. (Author/RK)

Rosch replied to the previous article in this edition of the Journal of Experimental Psychology and its evaluation of her research on the Cognitive Representations of Semantic Categories. (RK)

Two experiments are reported in which subjects viewed films of automobile accidents and then answered questions about events occurring in the films. Wording of questions regarding speed influenced subjects' estimates of speed. (Author/RM)

A study is reported investigating the question whether inferences made from sentences occur immediately in comprehension or are in part a function of the way material from sentences is stored in memory. (Author/RM)

The research study investigated the memory and metamemory abilities of four severely to profoundly deaf students with bilateral sensory-neural loss, between the ages of 9 and 20 years. Metamemory was investigated with four modified subtests identified as "story list,""study plan,""retrieval event," and "opposites-arbitrary." Encoding was…

Previous cognitive science research demonstrates how the Agent-action-Objective (AaO) paradigm controls the cognitive processes of differentiation and integration. The present discussion advances the process to the fourth of five phases. Of the four dependent variables emerging at this stage, two are discussed: zero processing and variations in…
