This study of 48 children with congenital blindness who attended mainstream schools focused on the tactile and haptic skills they needed in typical academic and everyday tasks. The results showed that, in general, the children mastered such tactile tasks, but some items posed special problems. (Contains 4 tables.)

The objective of the present study was to assess the development of luminance- and texture-defined static form perception in school-aged children. This was done using an adapted Landolt-C technique where C-optotypes were defined by either luminance or texture information, the latter necessitating extra-striate neural processing to be perceived.…

Infants with visual impairment often require additional interaction from adults to reinforce behaviors that lead to competency at mealtimes, but parental and professional confidence in teaching these skills is often limited. In the following collective case study, the authors, a speech/language pathologist (S/LP), occupational therapist (OT), and…

Everyday environments, even small regions within reach, vary dramatically in terms of material composition. Adapting one's manual behavior to such transitions can be considered to be an important element of skilled action. To investigate the origins of this ability, we presented 8-month-olds (n=24) and 10-month-olds (n=24) hard or soft objects on…

GRADES OR AGES: Four-, five-, and six-year olds. SUBJECT MATTER: Sensory experiences, including tactile, auditory, and visual. ORGANIZATION AND PHYSICAL APPEARANCE: The guide is divided into three sections, one for each of the above sensory areas. Each section lists materials and describes activities; illustrations are interspersed. The guide is…

Investigated the relative effects of developmental level and domain-specific knowledge on 4- to 9-year-olds' ability to identify and make similarity decisions about objects based on haptic or tactile information. Found that older children explored models more exhaustively, found more differentiating features, and made fewer errors than younger…

Lowenfeld (1945) developed a series of six instruments which could be used to identify perceptual abilities. For this study, the visually oriented person was defined as the objective viewer of the environment, while the haptic person was defined as a person who uses the eyes only when forced to do so and relates to his environment subjectively. He…

Four experiments studied the perception of the unity and boundaries of objects by 88 4-month-old infants who manipulated them out of the visual field. Infants perceived the unity/boundaries of these objects by detecting the motion patterns they themselves produced. Discrimination between motion patterns transferred from touch to vision. (SLD)

Argues that visuals constitute a language" in that they suggest physical objects . . . just as words signify their referents;" an adaptation of a paper presented at national convention of Department of Audiovisual Instruction, YNational Education AssociationI (Houston, Texas, March 28, 1968).

Examines the ability to differentiate appearance-reality and Level Two perspective-taking in tactile modality among a total of 92 children aged two-four years in three studies. The results indicate that three-year-olds find tactile appearance-reality and Level Two perspective-taking tasks easier than visual ones. (RJC)

In this article, we examine the extent to which children with autism and children with learning difficulties can be discriminated from their responses to different patterns of sensory stimuli. Using an adapted version of the Short Sensory Profile (SSP), sensory processing was compared in 34 children with autism to 33 children with typical…

The relationships of sense modalities included in the broad term "perception" are explored. Vision is a transmission from external world to brain. Ocular mobility and spatial organization abilities are important to vision as it is involved in the perceptual-cognitive process. Kinesthetic and visual behaviors are interrelated and are supplemented…

As a child matures from infancy to early childhood, a shift occurs in his sensory hierarchy from tactile to auditory to visual. The transition between the predominance of the auditory sense and visual sense takes place in about grades four and five. Although the sensory systems do not function singularly (but are integrated in the total action…
