COMPUTER GAMING AND INTERACTIVE SIMULATIONS FOR LEARNING: A META-ANALYSIS

Substantial disagreement exists in the literature regarding which educational technology results in the highest cognitive gain for learners. In an attempt to resolve this dispute, we conducted a meta-analysis to decipher which teaching method, games and interactive simulations or traditional, truly dominates and under what circumstances. It was found that across people and situations, games and interactive simulations are more dominant for cognitive gain outcomes. However, consideration of specific moderator variables yielded a more complex picture. For example, males showed no preference while females showed a preference for the game and interactive simulation programs. Also, when students navigated through the programs themselves, there was a significant preference for games and interactive simulations. However, when teachers controlled the programs, no significant advantage was found. Further, when the computer dictated the sequence of the program, results favored those in the traditional teaching method over the games and interactive simulations. These findings are discussed in terms of their implications for exiting theoretical positions as well as future empirical research.

Moderators of Stress in Parents of Children with Autism

Parents of children with autism experience more stress and are more susceptible to negative outcomes than parents of children with other disabilities. The present work examines the relationship between stressors, social support, locus of control, coping styles, and negative outcomes (depression, social isolation, and spousal relationship problems) among parents of children with autism. Fifty-eight parents completed surveys. Results indicated that several coping styles corresponded to negative outcomes. Furthermore, the relationship between stressors and negative outcomes was moderated by social support and coping style. Results are discussed in relation to applications for clinical practice.

When Member Homogeneity is Needed in Work Teams A Meta-Analysis

A meta-analytic integration of 57 effect sizes from 13 studies (567 teams, 2,258 participants) was performed to determine if groups that are homogeneous with respect to gender, ability level, and personality achieve higher levels of performance than teams that are heterogeneous on these attributes. Although individual studies often show marked differences between homogeneous and heterogeneous groups, the results of this integration show the combined effect sizes of these studies to be small, though not significant, in favor of heterogeneous groups. It appears that the significant effects found in many of the included studies can be attributed to the type and difficulty of the task used in the investigation. Implications for team construction are discussed.

Efficacy of relapse prevention: A meta-analytic review

Although relapse prevention (RP) has become a widely adopted cognitive-behavioral treatment intervention for alcohol, smoking, and other substance use, outcome studies have yielded an inconsistent picture of the efficacy of this approach or conditions for maximal effectiveness. A meta-analysis was performed to evaluate the overall effectiveness of RP and the extent to which certain variables may relate to treatment outcome. Twenty-six published and unpublished studies with 70 hypothesis tests representing a sample of 9,504 participants were included in the analysis. Results indicated that RP was generally effective, particularly for alcohol problems. Additionally, outcome was moderated by several variables. Specifically, RP was most effective when applied to alcohol or polysubstance use disorders, combined with the adjunctive use of medication, and when evaluated immediately following treatment using uncontrolled pre-post tests.

Team training in the skies: Does crew resource management (CRM) training work?

The aviation community has invested great amounts of money and effort into crew resource management (CRM) training. Using D. L. Kirkpatricks (1976) framework for evaluating training, we reviewed 58 published accounts of CRM training to determine its effectiveness within aviation. Results indicated that CRM training generally produced positive reactions, enhanced learning, and promoted desired behavioral changes. However, we cannot ascertain whether CRM has an effect on an organizations bottom line (i.e., safety). We discuss the state of the literature with regard to evaluation of CRM training programs and, as a result, call for the need to conduct systematic, multilevel evaluation efforts that will show the true effectiveness of CRM training. As many evaluations do not collect data across levels (as suggested by D. L. Kirkpatrick, 1976, and by G. M. Alliger, S. I. Tannenbaum, W. Bennett, Jr., & H. Traver, 1997), the impact of CRM cannot be truly determined; thus more and better evaluations are needed and should be demanded.

ANALYZING COMMUNICATION SEQUENCES FOR TEAM TRAINING NEEDS ASSESSMENT

Several models of team performance have suggested that a clearer understanding of team process is needed to determine better training formats and reduce crew-generated errors. The present study investigated the degree to which analyzing communication sequences would contribute to the understanding of effective crew process in two simulated flight tasks. The results indicate that pattern analyses reveal additional strong differences between performance groups that would have been overlooked by simple frequency counts of communication. In each case, the sequential analysis shed additional light on the communication patterns that characterize better-performing teams. These results are discussed in terms of their implications for team performance research and team training. Potential applications of this research include training needs assessment, training design, and performance measurement after training.

Measuring Team Knowledge: A Window to the Cognitive Underpinnings of Team Performance

The authors report an effort aimed at developing and evaluating measures of taskwork and teamwork team knowledge for teams in which members differ in knowledge backgrounds. These measures were used in a study with 36 teams to explore the cognitive underpinnings of team performance variations due to cross-training regime. The authors demonstrate that these measures are valid and provide team performance information that complements outcome and behavioral measures. Teams exposed to full cross-training acquired more taskwork and teamwork knowledge than control teams or teams exposed to a conceptual version of cross-training. Measures of team knowledge provide information regarding team task performance critical for system design and training programs.

Cerebral lateralization of spatial abilities: A meta-analysis

There is a substantial disagreement in the existing literature regarding which hemisphere of the brain controls spatial abilities. In an attempt to resolve this dispute, we conducted a meta-analysis to decipher which hemisphere truly dominates and under what circumstances. It was found that across people and situations, the right hemisphere is the more dominant for spatial processing. However, consideration of specific moderator variables yielded a more complex picture. For example, females showed no hemisphere preference while males showed a right hemisphere advantage. Also, no hemisphere preference was indicated for spatial visualization tasks while subjects performing spatial orientation and manual manipulation tasks displayed a predictable right hemisphere preference. These findings are discussed in terms of their implications for exiting theoretical positions as well as future empirical research.

The Impact of Cross-Training and Workload on Team Functioning: A Replication and Extension of Initial Findings

Although previous research has shown that cross-training team members improves team performance, a number of questions remain concerning the nature of cross-training. The current study provides an extension of previous cross-training research by investigating two theoretical issues: the nature of cross-training and the joint impact of cross-training and workload on team functioning. The study examined 40 three-person teams performing a simulated radar task. Results indicated that positional rotation was an effective cross-training method for highly interdependent tasks, that cross-trained teams developed a greater degree of interpositional knowledge than did teams that were not cross-trained, and that cross-training was important only under high-workload performance conditions. The current study suggests that the type of cross-training necessary to improve team performance may be related to the nature of the task and that cross-training may be effective in allowing teams to coordinate implicitly—that is, without the need to communicate overtly. Taken together with previous work, the results of this study indicate strong support for the efficacy of cross-training as a means to help teams perform well. Potential applications of this research include training for military, medical, and aviation teams

A Methodology for Enhancing Crew Resource Management Training

Human error is an ever-present threat to the safe conduct of flight. Recently, applied psychologists have developed an intervention, crew resource management (CRM) training, designed to help prevent human error in the cockpit. However, as it is commonly applied within the aviation community, CRM lacks standardization in content, design, delivery, and evaluation. This paper presents a discussion of an applied program of research aimed at developing a methodology for the design and delivery of CRM training within the Navy. This long-term, theoretically based program of aviation team research included identification of skills to be trained, development of performance measures, application of instructional design principles, and evaluation of the training delivery. Our conclusion indicates that a systematic methodology for developing CRM training can result in better performance in the cockpit. Actual or potential applications of this research include any task environment in which teams are interdependent.
