The Nobel Prize in Economics was awarded in 2002 for work on judgment and decision-making tasks that are the operational measures of rational thought in cognitive science. Because assessments of intelligence (and similar tests of cognitive ability) are taken to be the quintessence of good thinking, it might be thought that such measures would…

We studied developmental trends in 5 important reasoning tasks that are critical components of the operational definition of rational thinking. The tasks measured denominator neglect, belief bias, base rate sensitivity, resistance to framing, and the tendency toward otherside thinking. In addition to age, we examined 2 other individual difference…

This study examined the predictors of belief bias in a formal reasoning paradigm (a syllogistic reasoning task) and myside bias in two informal reasoning paradigms (an argument generation task and an experiment evaluation task). Neither cognitive ability nor thinking dispositions predicted myside bias, but both cognitive ability and thinking…

The article summarizes the four preceding articles on specific reading disability and emphasizes the presence of variability in all discussions of the topic. (DB)

The article summarizes findings of research on individual differences in reading ability, noting the primary effects of lack of phonological awareness on the ability to phonologically segment, analyze, and synthesize the speech stream. Other sources of individual differences are also addressed: early visual processes, naming processes, context,…

The effect of orthographic structure on the word search performance of good and poor third-grade readers is examined. (MP)

College students (n=349) completed an argument evaluation test in which they evaluated arguments about real-life situations. Argument quality and strength of prior beliefs were used to create an index of differences that were reliably linked to differences in cognitive ability and actively open-minded thinking. (SLD)

The domain specificity and generality of an important critical thinking skill was examined by administering nine reasoning and decision-making tasks to 125 adults. Performance across tasks displayed considerable domain specificity, but five tasks displayed moderate convergence. Performance on tasks that displayed domain generality was more…

A review of interactive models of reading combined with the assumption of compensatory processes indicates that compared to poor readers, good readers appear to have superior strategies for comprehending and remembering large units of text and are superior at context-free word recognition. (MKM)

Examined developmental and individual differences in tendencies to favor analytic over heuristic responses in three tasks (inductive reasoning, deduction under belief bias conditions, probabilistic reasoning) in children varying in age and cognitive ability. Found significant increases in analytic responding with development on first two tasks.…

Fourth and fifth graders marked on a checklist the titles and authors of children's books which they recognized. This measure of exposure to print was correlated with children's growth in reading ability as measured by standardized tests. Individual differences in growth in reading were significantly related to the measure. (BC)

Presents a framework for conceptualizing development of individual differences in reading ability that emphasizes the effects of reading on cognitive development and on "bootstrapping" relationships involving reading. Uses the framework to explicate some persisting problems in the literature on reading disability and to conceptualize…

The literature on individual differences in cognitive processes that operate at the text level is reviewed. Poor readers display comprehension deficits independent of word-decoding skill, due to deficient syntactic abilities and to more general metacognitive strategies. The general conclusions from this review and from Part One (ED 150 706) are…

Studied whether individual differences in print exposure and exposure to other media can account for individual differences in acquired declarative knowledge, controlling for confounds between experience and ability. Results with 268 undergraduates (90 males and 178 females) suggest that exposure is a significant contributor to knowledge…

Studied reading comprehension, vocabulary, general knowledge, and print exposure of 11th graders who completed reading battery 10 years earlier. Found that first-grade reading ability predicted all 11th-grade outcomes--even when cognitive ability was partialed out--and was linked to print exposure, even after 11th-grade reading comprehension…
