This article describes the formulation and execution of the Rainbow Project, Phase I, funded by the College Board. Past data suggest that the SAT is a good predictor of performance in college. But in terms of the amount of variance explained by the SAT, there is room for improvement, as there would be for virtually any single test battery. Phase I of the(More)
The authors describe a series of experiments that explore 3 major ability determinants of individual differences in skill acquisition in the context of prior theory (e.g., P.L. Ackerman, 1988) and subsequent empirical and theoretical research. Experiment 1 assessed the predictability of individual differences in asymptotic skill levels on the(More)
Previous research on basic information-processing tasks has suggested that there may be a dissociation between the underlying process determinants of task performance and associations with ability measures. This study investigates this dissociation in the context of a complex skill-learning task-an air traffic control simulation called TRACON. A battery of(More)
Online communities of practice cannot achieve organizational impact without member activity – discussion that leads to knowledge sharing, social network development, and strengthening of the professional community Several guidelines exist for facilitating ongoing, " organic " discussion, which stems from requests for information made by forum members.(More)
Practical intelligence as measured by tacit-knowledge inventories generally has shown a weak relation to other intelligence constructs. However, the use of assessments capturing specialized, job-related knowledge may obscure the generality of practical intelligence and its relation to general intelligence. This article presents three studies in which three(More)
CONTEXT The process whereby medical students employ integrated analytic and non-analytic diagnostic strategies is not fully understood. Analysing academic performance data could provide a perspective complementary to that of laboratory experiments when investigating the nature of diagnostic strategy. This study examined the performance data of medical(More)
