This study assessed the extent to which executive functions (EF), according to their factor structure in 5-year-olds (N = 244), influenced early quantity-number competencies, arithmetic fluency, and mathematics school achievement throughout first and second grades. A confirmatory factor analysis resulted in updating as a first, and inhibition and…

This study explored transactional associations among visuomotor integration, attention, fine motor coordination, and mathematics skills in a diverse sample of one hundred thirty-five 5-year-olds (kindergarteners) and one hundred nineteen 6-year-olds (first graders) in the United States who were followed over the course of 2 school years.…

Many assume that cognitive and linguistic processes, such as semantic knowledge (SK) and self-regulation (SR), subserve learned skills like reading. However, complex models of interacting and bootstrapping effects of SK, SR, instruction, and reading hypothesize reciprocal effects. Testing this "lattice" model with children (n = 852)…

At what point in reading development does literacy impact object recognition and orientation processing? Is it specific to mirror images? To answer these questions, forty-six 5- to 7-year-old preschoolers and first graders performed two same-different tasks differing in the matching criterion-orientation-based versus shape-based (orientation…

In a longitudinal study, auditory and visual temporal order thresholds (TOTs) were investigated in primary school children (N = 236; mean age at first data point = 6;7) at the beginning of Grade 1 and the end of Grade 2 to test whether rapid temporal processing abilities predict reading and spelling at the end of Grades 1 and 2. Auditory and…

A sample of 116 children (M = 6 years 7 months) in Grade 1 was randomly assigned to experimental (n = 60) and control (n = 56) groups, with equal numbers of boys and girls in each group. The experimental group received a program aimed at improving representation and transformation of visuospatial information, whereas the control group received a…

Evidence suggests that sensitivity to coherent motion (CM) is related to reading, but its role in the etiology of developmental dyslexia remains unclear. In this longitudinal study, CM sensitivity was measured in 31 children at family risk for dyslexia and 31 low-risk controls. Children, diagnosed with dyslexia in third grade (mean age = 8 years 3…

This study investigates the responses of 84 children, aged 6 years 3 months to 7 years 5 months, to questions dealing with the categories of physical causality and 2 causal demonstrations. (WY)

Results support the hypothesis that, with 6-year old children, the production of analytic responses on the Conceptual Style Test is a function of the instructions used. (Author/CB)

This study examined first graders' use of strategic behavior (looking more during study and categorizing during study) in response to perceiving instructions versus remembering instructions. (BRT)

These results suggest that previously published findings indicating that young children are unresponsive to issues of intentionality are methodological artifacts of the verbal assessment procedures employed. (Authors)

Issues include consistent individual differences in children's strategy choices, interpretation of differences within a framework, and the relation of differences to standardized test performance. (RJC)

Analyses revealed consistent support for the hypothesis that number conservation is developmentally prior to liquid quantity conservation. (Authors)

Assessed first and third graders' and undergraduates' knowledge of strategies appropriate to comprehension and memory. Also assessed their knowledge of task variables affecting comprehension and memorization tasks. Only undergraduates showed understanding of comprehension-memory distinction. Third graders showed some understanding of differential…
