Purpose: To review and assess theory and research supporting DIR/Floortime™, a method proposed for treatment of young children with autism spectrum disorders (ASD). Methods: Published materials describing the principles of DIR/Floortime™were evaluated. Published outcome research articles were assessed for the adequacy of their design and…

Despite external changes such as those of magnitudes, the functional properties of the visual system also improve with increased age. According to Jean Piaget's centration/decentration theory, the process of perceptual development might continue until adulthood and even after. However, perceptual development should not be understood in all of its…

Because visual short-term memory deficits are common in children with reading problems, a series of experiments were reviewed which examined the role of phonological processes in short-term memory. Results suggest that both developmental and individual differences in verbal memory span are related to efficient phonological processes. (Author/DB)

Examines current research on brain development, focusing on infants' ability to understand basic numerical concepts and arithmetic operations. Asserts that as the brain undergoes dramatic transformations, it already has a built-in capacity to understand basic numerical concepts. Recommends that parents and professionals engage in activities…

Outlines the patterns and processes of visual representation which occur during early childhood and suggests some differences that may be apparent in relation to the young gifted child. Stages of development are described and the use of children's drawings as indicators of giftedness is also outlined. (Author/CR)

This article summarizes the early development of the visual system within the context of the other sensory systems and preterm birth and relates this information to early intervention. Retinopathy of prematurely, ocular defects, cortical visual impairment and potential impact of the neonatal intensive care unit environment are discussed. (Contains…

Some recent research is examined on childrens' perception of pictures. Implications are drawn for those who create and use illustrated childrens' books. (SJL)

In the 1920s and 1930s, interpretations of reading readiness held that learning to read occurred at a specific point in cognitive development. Postponement of reading instruction until a child reached this stage of maturity was widely accepted at that time, and throughout the 1940s and 1950s. The 1960s marked a transition period in terms of…

The two chapters of this monograph deal with the issue of the existence of a perceptual grammar that influences reading proficiency, particularly initial reading proficiency. The first chapter indicates the importance of studying reading and writing in terms of readers' and writers' knowledge of visuo-spatial processing rules. It discusses…
