Investigated linkage between delay-of-gratification dimension of impulsivity and social information processing in 80 second-graders and 80 fifth-graders. Found that low-delay ability and younger participants made less use of social cues than did older and high-delay ability participants; however, these findings were qualified by grade and gender…

Whether relations between intelligence test performance and information processing measures depend on individual differences in speed-accuracy preferences rather than capacity limitations and whether the impact of strategic variables changes with increasing age or extraversion was studied with 83 adults ages 50 to 79 years. Results are discussed…

A model of cognitive slowing is proposed that correctly predicts a positively accelerated reaction between latencies of older and younger adults and provides a unified account of the effects of task complexity, practice, speed-accuracy tradeoffs, and fluctuations in individual performance. (SLD)

The relationship between elementary operations underlying processing of numerical information and performance on psychometrically derived ability measures requiring processing of numbers but defining separate ability factors was studied for 102 Air Force recruits (54 males and 48 females). Patterns of convergent and discriminate relationships for…

Examines information-processing differences among four types of readers differing in reading comprehension and speed. Finds that good comprehenders outperformed poor comprehenders on all types of tasks, but the results were less clear for the high- and low-speed readers. Proposes differences in working memory as a source of individual differences…

Examined the effects of instruction in bridging and problem-solving strategy, 2 specific components of mediational instruction, on behaviors of 10- and 11-year-old children during LOGO programing tasks. Describes two case studies demonstrating typical differences between children's performances under the different learning conditions. Supports the…

Presents a theory of cognitive development that postulates a general cognitive processing system, a hypercognitive system governing self-regulation, and specialized structural systems responsible for processing different reality domains. Suggests five principles that serve as organizational pivots of developing cognition. Reports the results of…

Examined task factors, cognitive processes, and individual differences as determinants of performance in 188 adults locating a position on a topographical map. Both spatial visualization ability and a visual learning style were found to be effective predictors of performance. A form of verbal strategy training produced significantly improved…

Tower of Hanoi has become a popular tool in cognitive and neuropsychology to assess a set of behaviors collectively referred to as executive functions. Substantial variability in performance on the Tower of Hanoi (TOH) disk-transfer task among normally functioning young adults, and potential contributions to these individual differences, were…

Our research reflects the current trend to relate individual differences in second language learning to underlying cognitive processes e.g., Robinson, 2002. We believe that such investigations, apart from being of practical importance, can also shed light on the cognitive mechanisms underlying the language learning process. Here we focus on the…

Though many cognitive abilities exhibit marked decline over the adult years, individual differences in rates of change have been observed. In the current study, biometrical latent growth models were used to examine sources of variability for ability level (intercept) and change (linear and quadratic effects) for verbal, fluid, memory, and…

This study adds to the growing literature linking children's experiences in the environment to individual differences in their developing skills in attention, memory, and planning. The authors asked about the extent to which stimulating and sensitive care in the family and in the child-care or school environments would predict these cognitive…

Theoretically, prospective memory retrieval can be accomplished either by controlled monitoring of the environment for a target event or by a more reflexive process that spontaneously responds to the presence of a target event. These views were evaluated in Experiments 1-4 by examining whether performing a prospective memory task produced costs on…

The recent No Child Left Behind legislation has defined a vital role for large-scale assessment in determining whether students are learning. Given this increased role of standardized testing as a means of accountability, the purpose of this article is to consider how individual differences in motivational and psychological processes may…

Individual differences in verbal/analytic and nonverbal/holistic cognitive strategies were studied in relationship to performance levels in spatial tasks, sex and handedness. Analytic processes are described as sequential, resulting in decomposition of stimulus information, and holistic processes, as parallel, involving information synthesis.…
