Three-dimensional (3D) object completion, the ability to perceive the backs of objects seen from a single viewpoint, emerges at around 6 months of age. Yet, only relatively simple 3D objects have been used in assessing its development. This study examined infants' 3D object completion when presented with more complex stimuli. Infants…

This study investigates the visual information storage capacity in 5-, 8-, 11-, and 21-year olds. A partial report technique is used to assess the amount of information that children can take in and what the course of information loss was over time. (DP)

This series of activities on spatial relationships was designed to help users acquire the skills of spatial visualization and orientation and to improve their effectiveness in applying those skills. The series contains an introduction to spatial orientation with several self-directed activities to help improve that skill. It also contains seven…

Studies the ability of 5-month-old infants to recall temporal information and use temporal organization by training them to fixate a hierarchically structured or unstructured sequence of stimuli which appeared in four spatial positions. Results are interpreted within a temporal organizational framework; infants appear to use organization within…

Examines the development of young children's analysis of spatial patterns--specifically, hierarchical letter and geometric forms. Suggests that although children as young as four years of age demonstrated substantial analytic competence, their ability to integrate the parts of the spatial array to form a coherent whole was weaker and more easily…

The diagnosis and treatment of early learning problems and their relation to visual development is the subject of a series of 12 articles. The optometric viewpoint expressed is that vision is learned. A child's method of organizing his world, and manifestations of his disorganized behavior, including poor early academic achievement, probably…

A program investigated the feasibility of training selected abilities so as to facilitate transfer among tasks requiring these abilities and thus reduce training time and increase personnel flexibility. An extensive review of relevant literature was a first step in this investigation. Undergraduate college students were used as subjects in an…

Describes a lesson in which instruction is initiated through the right cerebral hemisphere by using visualizations as concrete aids to learning. Explanations include a hand model which is used to illustrate the dynamics of guard cell activity of stomates and a paper folding model to show increase in surface area. (RT)

Conclusions derived from drawing research indicate that young children can be trained to see and respond to the distinctions of their observation and that these distinctions can enrich their drawing experiences. These distinctions include spatial information obtained from observation. Three basic factors influence young children's spatial…

This study investigated the relationship between intramodal and intermodal information processing and performance on traditional age appropriate tests of spatial and perceptual-motor abilities. The ability of 65 normal kindergarten, first grade and second grade children to match to either a tactile or a visual standard was assessed with a modified…

The purpose of this paper is to illustrate the parents' role in their child's visual guidance program, the philosophies behind the program, and the teacher's responsibility to child vision. The first chapter, on parent involvement, instructs them to provide an environment to stimulate intellectual growth and stresses the importance of the…

A scheme is presented for the development of perception and learning in which a hierarchy of skills begins with innate response systems and progresses through gross motor activities to more specialized motor systems represented by eye-hand coordination. The next stage of development, the control of ocular muscles, is discussed and the development…

Visual recognition, navigation, tracking, and imagery are posited to involve some of the same types of representations and processes. The first part of this paper develops a theory of some of the shared types of representations and processing modules. The theory is developed in light of neurophysiological and neuroanatomical data from non-human…
