Through Project EXCEL (Excellence in Community Elected and Appointed Leadership), 63 participants (Ohio county commissioners) completed simulation exercises in 7 assessment centers. Participants received personalized feedback on 15 behavioral dimensions. (SK)

This paper presents an analysis of the stability of principal components. Stability is measured by the expectation of the absolute inner product of the sample principal component with the corresponding population component. The usefulness and predictive validity of the model were supported through simulation. (SLD)

It is proposed that attributes of automatization depend on the strength of a processing pathway, and that strength increases with training. With the Stroop effect as an example, automatic processes are shown through simulation to be continuous and to emerge gradually with practice. (SLD)

Discussion of computer simulations as a form of computer-assisted learning (CAL) focuses on a framework for domain representation for an Intelligent Simulation Learning Environment (ISLE). Topics discussed include knowledge related to computer simulations; formalization of domain knowledge; and the conceptual domain model. (19 references) (LRW)

Describes a computer program that gives Fluxus exhibition attendees an opportunity to experience the Flux objects in the spirit in which they were originally created. Suggests that the computer program provides a virtual approximation to the original art works without damaging them. (RS)

New applications of computer-assisted training being developed include telecommunications, artificial intelligence, soft skills training, and performance support systems. Barriers to acceptance are development time, costs, and lack of human contact. (SK)

The scoring pattern of the Multiple Affect Adjective Check List--Revised (MAACL-R) (M. Zuckerman and B. Lubin, 1985) was studied under "simulate good" and "simulate bad" conditions and under instructional sets of "simulate" or "simulate with caution" with 320 college students. Results show that the MAACL-R…

Examined the degree to which coefficient alpha is affected by including items with different distribution shapes within a unidimensional scale. Computer simulation results indicate that reliability does not increase dramatically as a result of using differentially shaped items within a scale. Discusses implications for test construction. (SLD)

Examines connectionist simulations indicating that starting with simplified inputs or limited memory is not necessary in training recurrent neural networks to learn pseudo-natural languages; such restrictions hinder acquisition. Suggests that Gold's theorem and possible lack of explicit negative evidence do not implicate innate,…

Presents an approach to multidimensional unfolding that reduces the occurrence of degenerate solutions and conducts a Monte Carlo study to demonstrate the superiority of the new method to the ALSCAL and KYST nonmetric procedures for student preference data. (SLD)

Clarifies several issues regarding the effects of autocorrelated errors on Type I error in ordinary least-squares models. Demonstrates through Monte Carlo simulation the conditions under which distortion in Type I error is less than predicted by asymptotic theory. Suggests a recently developed small-sample method for time-series analyses. (SLD)

Used Monte Carlo methods to compare several measures of item-parameter drift, manipulating numbers of examinees and items and numbers of drift items. Overall, Lord's chi square (F. Lord, 1968) measure was the most effective in identifying items that exhibited drift. Discusses the usefulness of other methods. (SLD)

Studied results from five linking methods under the graded-response model using simulated data. Results show that differences in the linking coefficients are small. The five methods yielded similar results for longer common-item links with large sample sizes and when the distribution of item-location parameters matched the underlying trait…

Compared three methods for developing a common metric under item response theory through simulation. For smaller numbers of common items, linking using the characteristic curve method yielded smaller root mean square differences for both item discrimination and difficulty parameters. For larger numbers of common items, the three methods were…

Applied optimal design methods to the item-bank design of adaptive testing for continuous testing situations using a version of the weighted-deviations model (M. Stocking and L. Swanson, 1993) in a simulation. Independent and overlapping item banks used items more efficiently than did a large item bank. (SLD)
