Notes that speech intelligibility has traditionally been measured by presenting words mixed in noise to listeners for identification at different signal-to-noise ratios. The words are produced in isolation or in sequence contexts where the predictability of specific items can be varied. Emphasizes that the technique provides valuable data about…

In this study, non-French participants learned gender-appropriate adjectives for 24 French nouns. Findings indicate that learning the same set of feminine French nouns could be made more or less difficult when the nouns in the masculine category created more or less competition.

This article attempts to clarify issues that were discussed in a previous article, which was written in response to an article that focused on connectionism and language transfer. (33 references) (CK)

Maintains that Demetriou and his colleagues' project shows how developmental scientists can assess concepts from multiple frameworks and relate them through explicit modeling and targeted research to build explanations powerfully grounded in data and theory. Presents doubts related to specific conclusions because of issues related to the design of…

Uses a spatial model to examine the relationship between stimulus exposure, cognition, and affect. Notes that this model accounts for cognitive changes that a stimulus may acquire as a result of exposure. Concludes that the spatial model is useful for evaluating the mere exposure effect and that affective change does not require cognitive change.…

Based on Luria-Das information processing theory, hypothesized that 26 educable mentally retarded children would score significantly less well on relatively pure measures of planning ability than would 13 younger average ability students after students were matched on cognitive processing ability. Hypothesis was not supported by study. (Author/NB)

Whereas the writing process is recursive, Instructional Theory into Practice (ITIP) is a linear, sequential series of instructional decisions. By understanding the relationship between these two models, staff development and curriculum specialists can assist teachers by coordinating support group sessions and followup training using a common…

A parallel distributed processing model of visual word recognition and pronunciation is described. A key feature is the assumption that there is a simple, uniform procedure for computing a phonological representation from an orthographic representation for irregular words as well as regular words. (SLD)

Discussion of expert systems focuses on knowledge acquisition methodologies and their potential application to cognitive science research and the development of instructional materials. Topics discussed include subject matter experts; types of knowledge; structured interviews; task analysis; intelligent computer assisted instruction (ICAI);…

Examines the place of mental models in the process of knowledge construction, particularly by the relationship between mental models and computer models in that process. Analyzes and discusses children's use of spreadsheets to build their own computer models. Suggests that the process of building models on a computer may provide direct support to…

Examined whether age-related change in naming time reflects automatic access of familiar names because of greater familiarity with the named objects or global change in speed of processing. The path analyses and structural-equation modeling of 8- to 13-year olds were consistent with the second explanation. Time and age were linked to reading…

Describes a model of information processing that could be helpful in teaching students to interpret information. Four stages of information processing are discussed: judging suitability, understanding/comprehending, evaluating, and extracting. Examples based on task analysis and observations of students' work are included. (three references) (MES)

Addresses foundations of designing a bibliographic database for casual end-users, including the representation of knowledge, hierarchical schemata, cognitive processing of search problems, basic level categories of knowledge, and Boolean strategy in online searching. A hierarchical-based query model, data-item model, and idealized data model for…

Examines the phenomenon of semantic change with regard to color categories in closely related Mayan languages (Tzetal and Tzotzil) associated with radically different social milieux. It is argued that, although a model of individual cognition explains how color categories change at the basic level, a social model accounts for differences between…

Examined burnout among nursing assistants (n=245). Found that both stressor and appraisal variables influenced feelings of burnout. Stressor variable, frequency of disturbing patient behaviors, best explained feelings of reduced Personal Accomplishment. Appraisal variable, reaction to patient behaviors, best explained Emotional Exhaustion. Found…
