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)

A cell-by-cell analysis of finger movements of 16 blind adolescent braille readers was conducted to separate, catalog, and measure the components of scanning movements across braille cells as a function of reading proficiency. Results confirmed the superiority of bimanual reading and suggested that the two hands may perform different functions.…

Different materials that are used in manufacturing long cane shafts were assessed for their ability to transmit vibration and their sensitivity to tactile information, flexibility, and durability. It was found that the less flexible a cane shaft is, the better it transmits vibrations that are useful for discriminating surface textures and that…

In this systematic review of research, the author analyzes studies of neural cortical activation, brain plasticity, and braille reading. The conclusions regarding the brain's plasticity and ability to reorganize are encouraging for individuals with degenerative eye conditions or late-onset blindness because they indicate that the brain can make…

Two experiments investigated 5-month-old infants' amodal sensitivity to numerical correspondences between sets of objects presented in the tactile and visual modes. A classical cross-modal transfer task from touch to vision was adopted. Infants were first tactually familiarized with two or three different objects presented one by one in their…
