To clarify the relationships between reaction time (RT) variability and intelligence, RT distributions from 303 male Navy recruits were partitioned into 16 fast-to-slow latency bands calculated with measures of mental ability. The slowest bands (worst trials) were the best predictors of intelligence and working memory performance. (SLD)

Two ways of teaching a course in adolescent development and learning were compared. Sections of normal size were taught as usual, while large sections had instruction augmented with televised illustrations. With the exception of these illustrations, resources were the same for both classes and included a programed text. Results on two types of…

Two experiments involving 227 children aged 5 to 18 years suggest that working memory operates as a general system independent of the subject's reading skill and that dynamic testing procedures enhance predictions of reading performance. Individual differences in working memory do not appear restricted to an academic domain. (SLD)

The reliability of derived measures from 4 cognitive paradigms was studied using 19 Navy enlisted men (aged between 18 and 24 years). The paradigms were: graphemic and phonemic analysis; semantic memory retrieval; lexical decision making; and letter classification. Results indicate that derived scores may have low reliability. (SLD)
