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…

Using a single-subject alternating treatments reversal design, the effects of three conditions, tactile stimulation, auditory stimulation, and choice of the two, were compared on the math story problem solving of elementary students with attention problems. Students attempted and solved slightly more problems and engaged in fewer off-task…

This research was conducted to determine the effects of traditional instruction versus Contract Activity Packaged (CAP) versus Programmed Sequenced Learning (PLS) versus Tactual Resources (TR) on the achievement and attitudes of 32 second-year undergraduate teacher education majors enrolled in two classes of a required child-study course at a…

The study was undertaken to evaluate the nature of sensory dysfunction in persons with autism. The cross-sectional study examined auditory, visual, oral, and touch sensory processing, as measured by the Sensory Profile, in 104 persons with a diagnosis of autism, 3-56 years of age, gender- and age-matched to community controls. Persons with autism…

The paper reports on two experiments in Braille learning which compared blind and sighted subjects on the immediate recall of haptically-examined Braille symbols. In the first study, sighted subjects (N=64) haptically examined each of a set of Braille symbols with their preferred or nonpreferred hand and immediately recalled the symbol by drawing…

The purposes of this investigation were to compare an individual's magnitude and direction of error in three tests of kinesthetic perception, and to determine whether individuals tend generally to reduce, augment, or moderate stimuli on all three tests. A single group design was employed, using a sample of 34 male students. The variables of joint…

The purpose of the project was to gain information with which to improve the quality of tactual maps for the blind. Empirical studies of the pair-comparison type were conducted, using blind students as subjects, to determine discriminable sets of areal, linear, and point symbols made in plastic and to identify discriminable sets of linear and…

Even congenitally blind persons can picture things they have never seen, through an intuitive sense of perspective. (Author/BB)

Two experiments were conducted to (1) replicate the findings of habituation of behavioral responding to a tactile stimulus assuring state control and (2) demonstrate dishabituation either by reinstatement of responding to the original, habituated stimulus or to novel stimuli either within or between modalities. Subjects were newborn Caucasian…

Surveys research on the differences between haptic and visual learners and describes a haptic testing program to help industrial arts teachers work with haptic students. (SK)

In three experiments, sighted college students tried to learn the names of the first 10 symbols of the braille alphabet. In Experiments 1 and 2, visual examination of the symbols enhanced learning. In Experiment 3, similar results were obtained when standard size braille symbols were used during the study trials. (Author)

All Ss' accuracy decreased with increasing task difficulty. Accuracy of nonretarded Ss did not differ as a function of visual status. Blind retarded Ss were more accurate than were sighted retarded Ss. (Author)
