Reviews efforts to develop computer-based, case-management simulations for use in training rehabilitation counselors. Describes exemplary systems. Discusses issues related to research and development of computer software in case-management training. (Author)

The Feature Integration Theory of visual search proposed by A. M. Treisman and others (1980, 1986) is reviewed, and a modified Guided Search theory is presented in which the parallel stage guides the serial stage as it chooses display elements to process. A computer simulation illustrates the theory. (SLD)

A bidimensional 2-parameter logistic model was applied to data generated for 2 groups on a 40-item test. Item parameters were the same across groups; correlation across the 2 traits varied. Results indicate the need for caution in using item-response theory (IRT)-based invariance indexes with multidimensional data for these groups. (TJH)

Computer simulations are described in which pairs of simulated individuals in groups play a prisoner's dilemma game, with the choice to cooperate determined by one of three simple heuristics. Results reveal that the prevalence of cooperation depends on the heuristic used, value of the payoff, and the social comparison process. (SLD)

The parallel distributed processing model of visual word recognition in reading developed by Seidenberg and McClelland (1989) is extended through simulation. A response by Seidenberg and McClelland recognizes merits of the expanded model and outlines requirements for supplanting their original model. (SLD)

A discipline in which scientists seek to simulate and synthesize lifelike behaviors within computers, chemical mixtures, and other media is discussed. A computer program with self-replicating digital "organisms" that evolve as they compete for computer time and memory is described. (KR)

Simulated population data were used to compare relative performances of the modification index and C. Chou and P. M. Bentler's Lagrange multiplier test (a multivariate generalization of a modification index) for four levels of model misspecification. Both indices failed to recover the true model except at the lowest level of misspecification. (SLD)

Coordination is a key issue in the design of organizational structures and processes. In this article, the authors propose a body of concepts that support the modeling and computer simulation of organizational processes and organizational coordination. Three aspect models are described that highlight different coordination aspects, and future…

Describes the developmental process used to visualize the calcium ATPase enzyme of the sarcoplasmic reticulum which involves evaluating scientific information, consulting scientists, model making, storyboarding, and creating and editing in a computer medium. (Author/CCM)

Discusses how to train teams in problem-solving skills. Topics include team training, the use of technology, instructional strategies, simulations and training, theoretical framework, and an event-based approach for training teams to perform in naturalistic environments. Contains 68 references. (Author/LRW)

Examines instructional computer simulation from a Heideggerian point of view, claiming that traditional conceptions of simulation do not account for important characteristics of existence, namely anxiety and waiting. Discusses Heidegger's conception of Bestand, or standing reserve, and suggests implications for instruction. (Author/LRW)

Discussion of the four basic types of educational simulators that are available foe medical education for problem-based, interactive learning focuses on the role of microsimulators. Describes educational medical simulators and suggests that the development of microsimulators should focus on the intelligent, educational feedback in the debriefing.…

SUSTAIN (Supervised and Unsupervised STratified Adaptive Incremental Network) is a model of how humans learn categories from examples. SUSTAIN initially assumes a simple category structure. If simple solutions prove inadequate and SUSTAIN is confronted with a surprising event (e.g., it is told that a bat is a mammal instead of a bird), SUSTAIN…

Four experiments explored participants' understanding of the abstract principles governing computer simulations of complex adaptive systems. Experiments 1, 2, and 3 showed better transfer of abstract principles across simulations that were relatively dissimilar, and that this effect was due to participants who performed relatively poorly on the…

Computer aided design (CAD) has been producing 3-D models for years. AutoCAD software is frequently used to create sophisticated 3-D models. These CAD files can be exported as 3DS files for import into Autodesk's 3-D Studio Viz. In this program, the user can render and modify the 3-D model before exporting it out as a WRL (world file hyperlinked)…
