Early fine motor ability is significantly associated with later achievement, even after controlling for typical child-level predictors of school outcomes. Previous longitudinal studies have confirmed this but typically have not included low-income, at-risk populations. Research has distinguished two different aspects of fine motor skills: those…

The relations among various spatial and mathematics skills were assessed in a cross-sectional study of 854 children from kindergarten, third, and sixth grades (i.e., 5 to 13 years of age). Children completed a battery of spatial mathematics tests and their scores were submitted to exploratory factor analyses both within and across domains. In the…

The contribution of the three core components of working memory (WM) to the development of mathematical skills in young children is poorly understood. The relation between specific WM components and Numerical Operations, which emphasize computation and fact retrieval, and Mathematical Reasoning, which emphasizes verbal problem solving abilities in…

The objective of the investigation was to develop and test procedures for training children in coordination of projective space. (Projective concepts involve apparent distance, relative position, shape of figures, and other topological factors. A person with a command of projective space sees objects as a coordinated system of figures in space.) A…

Investigates whether viewers of different ages are aware that camera lenses manipulate the apparent velocity and distance of events presented on television. Suggests that younger viewers do not understand how television production techniques manipulate perceptual information and may thus be misled by their use. (PD)
