Discusses problems in academic research and their effects on libraries. Topics discussed include the trend toward rapid publication in the scientific fields; competition for academic research and development funding; the relationship between federal funding and publications; the role of libraries in the research process; and the role of vendors.…

Discussion of hypertext structures focuses on three studies of preservice teachers that assessed the effects of different methods of explicitly mapping expert knowledge structures onto hypertext on the acquisition of structural knowledge. Topics addressed include time on task, semantic networking, cognitive limitations of browsing behavior, and…

Describes a study that was conducted to examine the effects of captioned video material of varying difficulty on intermediate and advanced English-as-a-Second-Language (ESL) students' comprehension with videotaped episodes presenting low and high audio/video correlation. Captions were found to be more important for low audio/video correlation. (17…

A study of logical reasoning ability of endusers searching a CD-ROM index and its correlation to searching performance was conducted at the University of Illinois at Urbana-Champaign. Findings showed a correlation between cognitive skills and citation selection and indicated that computer system design can be improved using a cognitive engineering…

Describes a study that was conducted to examine gender differences in attitudes toward computers among high school students. Highlights include sex role behavior; students' interest in computers; stereotypes about computer users; self-confidence in ability to learn and use computers; and students' perceptions of parents' and teachers' attitudes…

Describes a study of undergraduates that examined the effects of behavioral versus cognitive review strategies on learning outcomes and depth of processing during computer-based instruction. Near and far transfer learning are discussed, the use of locus of control is explained, and posttest differences are examined. (eight references) (LRW)

A retrospective chart review was used to examine sexual behaviors and cognitive impairment in 200 youth (ages 5-18) with serious mental illness. Lower IQ was associated with increased sexual acting-out. For more serious victimizing sexual behaviors, only verbal IQ differences were statistically significant. Overall, sexual behavior disorders were…

Discussion of the appropriateness of evaluation criteria and measures for information retrieval focuses on a study that investigated the appropriateness of 20 measures, including precision and recall, for evaluating interactive information retrieval performance representing 4 major evaluation criteria. The importance of user satisfaction in…

This study investigated the concurrent validity of the Mayes Motor Free Compilation (MMFC) using the mental scale of the Bayley Scales of Infant Development (BSID) as the criterion variable with 50 typically developing preschool-aged children. Results indicated that the MMFC and the BSID scores were significantly and positively correlated.…

In a study of 696 learners, the authors found that stress associated with challenges in the learning environment had a positive relationship with learning performance and that stress associated with hindrances in the learning environment had a negative relationship with learning performance. They also found evidence suggesting that these…

This prospective study examined whether interdependent self-construal (collectivism), independent self-construal (individualism), family cohesion, and social support would predict levels of self-esteem among Vietnamese American adolescents. Standardized self-report measures of family cohesion, social support, and self-esteem, as well as a measure…

Computational models of infant categorization often fail to elaborate the transitional mechanisms that allow infants to achieve adult performance. In this article, we apply a successful connectionist model of adult category learning to developmental data. The Supervised and Unsupervised Stratified Adaptive Incremental Network (SUSTAIN) model is…

This study examined the influence of demographic characteristics, risk behaviors, knowledge, and psychosocial variables on HIV testing among a sample (n = 551) of young African-American men who have sex with men (MSM) from three cities--Atlanta (n = 241), Birmingham (n = 174), and Chicago (n = 136). Among the entire sample of young men, age,…
