Describes a computational model of high-dimensional context space: the Hyperspace Analog to Language (HAL). Shows that HAL provides sufficient information to make semantic, grammatical, and abstract distinctions. Demonstrates the cognitive compatibility of the representations with human processing; and introduces a new methodology that extracts…

Explores role of cognitive efficiency in interaction planning and plan performance of undergraduate students--one study explicated the concept of cognitive efficiency relating to communication processes; two others aimed at extending existing plan-based theorizing. Suggests cognitive efficiency and interaction experience are at the root of…

ACT-R is a theory of cognition that is capable of learning the relative usefulness of alternative rules. A model using this implicit procedural learning mechanism is described that explains results from a concept formation task created by McDonald and MacWhinney (1991), a role assignment created by Blackwell (1995), and a new role assignment…

Illustrates "hard" and "soft" theoretical constraints of cognitive structures and examines ways in which the learning mechanism feature of the Soar architecture places hard constraints on all models that use the feature. The relationship between architecture and model in terms of the degree to which a model is compliant with constraints set by the…

Offers a commentary on five contributions to recent developments in the study of cognitive development that have been selected for this special issue. The relevance of each author's paper to issues that are central to cognitivists today and post-Piagetian developmental psychologists is discussed, and the overall need of evolutionary models to…

Reviews studies on the cognitive mechanisms underlying creative thought and proposes a general model. This model holds that creative thought involves interactions among a number of distinct cognitive components. Some of the implications of this model for the design of effective educational programs are discussed. (Author/CR)

Seeks to identify some of the issues associated with the role of models in scientific explanations. Develops a typology of explanations and explores the notion of appropriateness in scientific explanations. Investigates the nature of models and their contribution to explanations. (DDR)

Presents a positive response to Sampson et al.'s article (this issue [2000]) describing a cognitive-information processing (CIP) framework useful for improving career services. Asserts that the authors strike an appropriate tone of optimism and caution that matches the article author's own experience as a practitioner and a teacher of the CIP…

Investigates whether a well-defined coaching process used at the moment of anger will help students internalize the cognitive processes learned in counseling sessions and enable them to use the anger management strategies independent of coaching. Offers school counselors reasons to implement such a model as an adjunct to individual or small group…

Four experiments examined very young infants' expectations about containment events. Found that 2- to 3.5-month-olds recognized that objects could be lowered inside a container with an open but not a closed top. Three-and-a-half-month-olds realized that objects could not pass through the container's back wall and should have moved with it to a new…

In some psycholinguistic models, processing is characterized by generation of multiple outputs using information from higher processing levels. Such models are considered autonomous in word recognition domain but interactive in sentence processing domain. This confusion arises not from differences between lexical and syntactic processing, but from…

Discussion of critical thinking focuses on conditions for effective collaborative learning and the potential for the Web to support critical thinking in knowledge-based communities. Highlights include collaborative learning; collaborative teams; thinking skills development; instructional strategies; and collaborative learning models that include…

Deals with two compromise strategies: (1) embedded language islands (EL Islands), and (2) "bare forms" in code switching (CS) within the projection of complementizer. These elements are discussed within the framework of the Matrix Language Frame Model. Shows how this model provides an explanatory account for the occurrence of both EL…

Investigated three models that permit restricted examinee control over revising previous answers in the context of adaptive testing, using simulation. Two models permitting item revisions worked well in preserving test fairness and accuracy, and one model may preserve some cognitive processing styles developed by examinees for a linear testing…

Data from 2,443 Korean employees were used to test a dual-process model theorizing that job satisfaction and organizational support are key emotional and cognitive processes influencing organizational commitment. Results show that the two processes operate through independent channels to influence the impact of work experience on commitment.…
