As children develop, their information-processing speed (PS) increases, and they retain more information in working memory (WM); these changes have been hypothesized to drive age-related improvements in reasoning and problem solving. For example, in Fry and Hale’s (1996) cascade model, developmental change in PS increases the functional capacity of WM, which in turn facilitates reasoning. Studies have shown that developmental increases in PS and WM during childhood and adolescence predict… Expand

Longitudinal evidence linking processing speed to the development of reasoning.
The findings suggest that variations in processing speed may constrain the development of reasoning, directly and perhaps indirectly. Expand
Extended cascade models of age and individual differences in children's fluid intelligence
Abstract Children's cognitive abilities (e.g., processing speed, working and secondary memory, and fluid intelligence) improve with age, but the relationships among these abilities are not wellExpand
A test of the cascade model in the elderly
Abstract The cascade theory (Fry & Hale, 1996) posits that developmental changes in perceptual speed in childhood increase the capacity of working memory, which increases fluid reasoning performance.Expand
Working memory, attention, and mathematical problem solving: A longitudinal study of elementary school children.
The role of working memory (WM) in children's growth in mathematical problem solving was examined in a longitudinal study of children (N = 127). A battery of tests was administered that assessedExpand

Children ’ s higher order cognitive abilities and the development of secondary memory
ties both improve with age, but the nature of the relation between these two developmental trends is not yet well understood. Much recent research on higher order cognitive abilities in adults hasExpand
Relations between Preschool Children’s Fine Motor Skills and General Cognitive Abilities
ABSTRACT An increasing number of findings suggest that cognition is grounded in sensorimotor experiences. Research suggests that fine motor skills (FMS) link to cognitive abilities. Existing studies,Expand
Processing speed, working memory and reasoning ability from childhood to old age
Abstract The study investigated whether theoretical causative relations among declining cognitive abilities during adulthood and old age conform to a literal reversal of improving cognitiveExpand
Sustained Attention and Its Relationship to Fluid Intelligence and Working Memory in Children
Understanding individual differences in intelligence remains an interesting research question, even with more than a century of empirical research and large numbers of models and theories. We knowExpand
Relations between speed, working memory, and intelligence from preschool to adulthood: Structural equation modeling of 14 studies
Abstract We posit that fluid intelligence (Gf) develops in four cycles, with two phases in each cycle, each distinctly connected with changes in processing speed and working memory. NewExpand


Processing Speed, Working Memory, and Fluid Intelligence: Evidence for a Developmental Cascade
Processing speed, working memory capacity, and fluid intelligence were assessed in a large sample (N = 214) of children, adolescents, and young adults (ages 7 to 19 years) Results of path analysesExpand
In press, Psychological Science Rethinking Speed Theories of Cognitive Development: Increasing the Rate of Recall Without Affecting Accuracy
Researchers have suggested that developmental improvements in immediate recall stem from increases in the speed of mental processes. However, that inference has depended on evidence from correlation,Expand
Sources of developmental change in children's word-problem performance.
This study was designed to examine the roles of domain-specific and general information-processing skills in developmental change in children's performance on arithmetic word problems. In 2 studies,Expand
Individual differences in working memory and reading
Individual differences in reading comprehension may reflect differences in working memory capacity, specifically in the trade-off between its processing and storage functions. A poor reader'sExpand

The chapter concludes by discussing the question of how adolescent cognition differs from that of children and of how dual-process theories can be usefully employed in framing future research on adolescent social and cognitive development. Expand
Inductive and Deductive Reasoning
According to traditional logic, arguments can be either inductive or deductive. Sometimes, it is difficult to determine which category an argument might be in. However, there are some key conceptsExpand
