This article describes a visual assessment procedure (VAP) which evaluates capacity, attention, and processing (CAP) of infants and preschool children with visual impairments. The two-level battery considers, first, visual capacity and basic visual attention and, second, visual perceptual and cognitive abilities. A theoretical analysis of the…

Three experiments investigated use of visual input and body movement input arising from movement through the world on spatial orientation. Experiments involved infants searching for a toy hidden in one of two containers. Findings indicated that search was best after infant movement in a lit environment prior to searching; all other conditions led…

Three experiments examined whether 8.5-month-olds considered an object's width and compressibility when determining whether it could be inserted into a container. Results suggested that infants realized that large balls could fit into large but not small containers, whereas small balls could fit into both containers. Infants understood that large…

Investigated early determinants of infants' self--other discrimination when presented with a live image of themselves or another person that was either contingent or contingent with delay. Found that infants 4 months and older perceived and acted differently when facing the image of themselves compared to that of another; 9-month-olds showed more…

We asked 22 right brain-damaged (RBD) patients and 11 elderly healthy controls to perform hand-pointing movements to free-field unseen sounds, while modulating two non-auditory variables: the initial position of the responding hand (left, centre or right) and the presence or absence of task-irrelevant ambient vision. RBD patients suffering from…

Previous reports have demonstrated that the comprehension of sentences describing motion in a particular direction (toward, away, up, or down) is affected by concurrently viewing a stimulus that depicts motion in the same or opposite direction. We report 3 experiments that extend our understanding of the relation between perception and language…

Five experiments investigated the recognition of proper names and common nouns using the lexical decision paradigm. In Experiments 1-3 the case of the initial letter of written stimuli was systematically varied. An advantage was consistently found for proper names written with the first letter in capital. Crucially, response times to proper names…

This paper studied whether abnormal P3 amplitudes in PDD are a corollary of abnormalities in ERP components related to selective attention in visual and auditory tasks. Furthermore, this study sought to clarify possible age differences in such abnormalities. Children with PDD showed smaller P3 amplitudes than controls, but no abnormalities in…

AN ANNOTATED BIBLIOGRAPHY OF TEN STUDIES OR WRITINGS ON PROBLEMS RELATED TO VISUAL PERCEPTION PUBLISHED BETWEEN 1954-1964 IS PRESENTED. THIS ARTICLE APPEARED IN "THE READING TEACHER," VOLUME 20, NOVEMBER 1966. (RH)

Reviews the ideas included in and the debate spawned by the author's paper at the 1974 International Intervisitation Program meeting in Britain. The paper questioned systems theory's adequacy as an exclusive explanation of organizations. (IRT)

Describes an experiment in which the rate of habituation of fixation of 12-week-old infants to a homogeneous stimulus series where a cube was presented in different orientations was contrasted with the rates of habituation to various heterogeneous series where a cube was alternated with some other solid.

Argues that pointing emerges as a component of action-for-self: selective orienting to salient (usually moving or changing things). Pointing with vocalization, followed by pointing with naming, indexes the child's shifting focus of attention. Evidence that pointing emerges for the purpose of intentional communication is lacking.
