This article investigates categorical perception as a phenomenon which can be understood in terms of adaptation level theory. Data from four experiments, two visual and two tactual-kinesthetic, supports the idea that categorical perception is a pervasive characteristic of perceptual organization. (JAZ)

The use of a nonvisual tactual and auditory tutorial method to teach initial reading skills to 16 reading disabled children (ages 7 to 14) was evaluated. The method was shown to be less effective than sighted methods. (DB)

Results are discussed in terms of cognitive growth, the psychoanalytic notion of ambivalence, the role of stimulus context in eliciting laughter or fear, and a possible adaptive, stimulus-maintaining function of laughter. (Authors)

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). (Editor/RD)

A revised concept of multimodality, multisensory instruction which minimizes the visual modality is suggested to deal primarily with the severe spelling difficulties of the dyslexic and of others with a similar language problem. (Author/SW)

Infants ranging from 6 to 12 months were randomly assigned to one of three conditions: (1) allowed to look at a specified object, (2) allowed to look at and manipulate it, or (3) allowed to look at the object and to manipulate the transparent box in which it was encased. (JMB)

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)

Explored in 2 studies 3- and 4-year-olds' understanding that the 5 senses can each lead to different types of knowledge. Found that 3-year-olds performed significantly poorer than 4-year-olds on all tasks, suggesting a marked transition in children's ability to recognize the origin of their modality-specific knowledge between 3 and 4 years.…

Recent research indicates that by 4.5 months, infants use shape and size information as the basis for individuating objects but that it is not until 11.5 months that they use color information for this purpose. The present experiments investigated the extent to which infants' sensitivity to color information could be increased through select…

The study examined modality effects in the learning of Braille through providing a variety of either study or test trials in either the visual or haptic modalities. Subjects were 144 right handed college students. Results supported previous experiments demonstrating the visual modality superior to the combined visual-haptic or the haptic modality…

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…

This guide describes and illustrates 50 perceptual games for preschool children which may be constructed by teachers. Inexpensive, easily obtained game materials are suggested. The use of tactile and visual perceptual games gives children opportunities to make choices and discriminations, and provides reading readiness experiences. Games depicted…

Sixty-nine students in grades 9, 10, and 11 were tested with three of Viktor Lowenfeld's visual-haptic tests in an attempt to ascertain whether students at these levels segregated in a fashion similar to Lowenfeld's sample. Respondents were spread over the visual-haptic continuum as Lowenfeld suggested they should be. However, a large and…

Analysis of 40 first-grade children's performance on two discrimination learning problems revealed that children do transfer dimensional information between the visual and tactual modalities. (Author/JMB)

Infants of 12 months were tactually familiarized with either a hard or an elastic substance. Subjects subsequently were shown films of objects moving in patterns characteristic of either hard or elastic objects, and their eye movements were detected. Results suggested that quite young infants detect intermodel invariants specifying some substances…
