Background: To understand how the human brain organises the information, how prototypes are handled in the categorisation system, researchers have pointed out that there may be a relationship between visual perception and concept acquisition. Aim: This study was conducted to examine the effect of a concept education programme, developed on the…

Object substitution masking (OSM) is said to occur when a perceptual object is hypothesized that is mismatched by subsequent sensory evidence, leading to a new hypothesized object being substituted for the first. For example, when a brief target is accompanied by a longer lasting display of nonoverlapping mask elements, reporting of target…

This study investigated whether object-picture discrepancy occurs because preschool children regard pictures as significates rather than as signifiers. Results indicated the children did not consistently respond to objects and their pictorial representations equivalently. (Author/DB)

Examines how children's responses to questions about object terms varied across objects and the degree to which children specified common and conventional values for different object dimensions. (HOD)

A LONGITUDINAL STUDY WAS PERFORMED WHICH FOLLOWED THREE GROUPS OF CHILDREN (CULTURALLY DISADVANTAGED, AVERAGE, AND CULTURALLY ADVANTAGED) THROUGH GRADE THREE IN AN ATTEMPT TO DETERMINE THE RELATIVE IMPORTANCE OF THE DEVELOPMENT OF CERTAIN PERCEPTUAL FACTORS ON SUCCESS OR FAILURE IN BEGINNING READING. INSTRUMENTS USED WERE SELECTED TO IDENTIFY…

Reviews the research literature on the abilities of infants to categorize visual information on dot patterns; schematic faces; hue; and orientation. (HOD)

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…

The relationship between conceptual complexity and stimulus saliency was explored in a 3 x 4 factorial design using 144 undergraduates. Levels of complexity were represented by varying the ratio of relevant-to-irrelevant dimensions (1:3, 2:2, and 3:1). The saliency factor varied according to the discriminability between each attribute within…

Studies five-year-olds' relative number judgements of small and large number displays with and without perceptual aids. Children were found to respond to local rather than global density differences and to benefit from the provision of perceptual aids on both small and large number displays. (Author/AS)

A detailed program for the development of pre-reading visual perceptual skills in young children is presented which provides benefits to both teacher and child due to its scope and flexibility. The program is primarily visual-motor, providing at the same time experiences in language and concept development. The prescribed sequence of lessons…

The technique of factor analysis was used to explore the structure of five batteries of readiness tests (Gates Reading Readiness Test, Developmental Tests of Visual Perception, Metropolitan Readiness Tests, Specially Constructed Readiness Test by Olson, and Wechsler Intelligence for Children) as predictor variables for the Stanford Achievement…

Reports on a study in which children aged 7 to 9 years and 11 to 13 years were asked to judge which one out of three wooden blocks would float, given weight and volume information for each block relative to a block that was known to float. Indicates that judgments may have been based on the size-weight illusion. (HOD)

Examined perception of object unity in partial occlusion in 72 infants. Recorded how long subjects looked at a display of complete and incomplete rods. In test and control conditions, infants looked longer at broken rods than at complete rods, suggesting that infants' cognitive, visual, or attentional skills may be insufficient to support…

Presented are remedial activities for use by the classroom teacher with learning disabled elementary school children in her regular class. An introductory section discusses specific learning deficits, general motor coordination deficits, and behavior manifestations. Offered are 15 generalizations about teaching the learning disabled child such as…
