Molecular models are described which are suitable for illustrating the nucleic acids. The same principles used to construct these could be applied to models of polypeptides. (BB)

The Prisoner's Dilemma (PD) game demonstrates how cooperative or competitive choices influence decision making between two people or groups. A study of 48 college students tested an infinite-choice, continuous-time version of the PD. Results indicated that oscillatory cooperation was the predominant over-time behavior, that players matched…

Demonstrates how principles of simulation help students develop working models or prototypes. Explains how computer software enables this process for learners with only basic computer knowledge. (SK)

Presents a design framework that incorporates integrated structures for modeling knowledge and skills, designing tasks, and extracting and synthesizing evidence. Illustrates these ideas in the context of a project that assesses problem solving in dental hygiene through computer-based simulations. (SLD)

Synthesizes lessons from school finance research that employs computational structural models to investigate different policy proposals. Suggests that full equilibrium analysis may lead to outcomes that differ from those predicted by partial equilibrium models. (Contains 50 references and 47 notes.) (JOW)

Describes an activity that would be useful for any level biology class discussing recombinant DNA technology to help students visualize the step-by-step process involved. (JRH)

Studied whether ordered latent class models can be used as nonparametric item response theory (NIRT) models to scale polytomous models. Simulation findings show that the Bayesian estimation method presented can handle the inequality restrictions on the parameters and the sparseness of the data quite well. (SLD)

The SeLective Attention Model (SLAM) performs visual selective attention tasks and demonstrates that object selection and attribute selection are both necessary and sufficient for visual selection. The SLAM is described, particularly with regard to its ability to represent an individual subject performing filtering tasks. (TJH)

The Shortlist model is presented, which incorporates the desirable properties of earlier models of back-propagation networks with recurrent connections that successfully model many aspects of human spoken word recognition. The new model is entirely bottom-up and can readily perform simulations with vocabularies of tens of thousands of words. (DR)

Reviews the literature on debriefing and identifies the essential elements and phases of the debriefing process. A model for systematic assessment of debriefing is presented which consists of five sets of questions that focus on learning objectives, situational constraints, the debriefing strategy, implementation of the strategy, and the…

Describes a computer-based connectionist-type network model that correctly identified the gender of a set of French nouns, relying solely on information inherent in the nouns' structures, in the absence of explicit rules for evaluating nouns, through discovering criterial gender-specific features through examples of masculine and feminine nouns.…

The relationship between recognition and recall, especially the orderly recognition-failure function relating recognition and the recognizability of recallable words, was investigated using a composite holographic associative recall-recognition memory model (CHARM) in 10 series of computer simulations. Support for the model is demonstrated. (SLD)

A theoretical integration of the storage and processing functions of working memory in language comprehension is presented. A computational theory is described in which storage and processing are fueled by activation. Capacity is expressed as the maximum amount of activation available in working memory for either storage or processing. (SLD)
