This study was designed to determine the relationship between the Lowenfeldian visual-haptic (perceptual) and the Piagetian concrete-formal (operational reasoning) continua. The study also investigated the relationship between age, sex, academic goal, academic preference, and a person's perceptual aptitude or intellectual reasoning abilities.…

In the analysis of ability structure and loss of vision, 228 blind persons (153 male, 75 female) heterogenous in respect to chronological age, sex, degree of blindness, age at onset, and duration, were compared to sighted controls. A test battery was administered which included tests for verbal comprehension, mental arithmetic, spatial ability,…

British and Zambian children were compared on their abilities to reproduce patterns, from tactile and visual presentations, by modeling, drawing, and gesturing. Age, sex, and intelligence variables were analyzed. Results suggested that cross-cultural differences in these tasks reflect differences in specific perceptual skills rather than broad…

Witelson found that boys but not girls showed right-hemisphere specialization for tactile-spatial processing as early as six years. Witelson's task was administered to 46 normal four- and five-year olds. Both sexes showed right-hemisphere specialization. No sex differences appeared either in specialization or in overall performance. (Author/SJL)

A total of 100 3- and 5-year-old children were trained and assessed individually on the concept of equilateral triangle at three levels of attainment: concrete, identity, and classificatory. Five training conditions existed: (1) visual inspection; (2) visual inspection and verbal orienting instruction; (3) visual inspection, free haptic activity,…

A study involving 29 sighted and 22 blind children in grades 3-12 was conducted to determine whether there are grade, sex, and handedness group differences in texture preferences and whether such preferences effect discrimination accuracy. (SBH)

Results indicated that clients who were touched evaluated the counseling experience more positively than no-touch subjects. Stronger effects occurred when clients were touched by an opposite-sex counselor. (Author)

Two studies examined the effects of handedness on braille learning. Experiment 1 featured 64 sighted undergraduates at North Carolina State University, all of whom were right-handed and had no experience with braille. Results revealed that females outperformed males, but that, contrary to expectation, no significant effects of handedness were…

A 2 (touch-no touch) x 2 (sex of confederate) x 2 (sex of subject) between subjects design tested the affective and evaluative consequences of receiving an interpersonal touch in a Professional/Functional situation. It was found that the affective and evaluative response to touch was uniformly positive for females, who felt affectively more…

Using Jean Piaget's theory of spatial development, a study was undertaken to identify the development of spatial concepts in 48 blind, partially sighted, and sighted 4-to-7-year-old children through the use of tactual recognition of shapes. (Author/PHR)

The purposes of this study were to investigate possible relationships between haptic abilities and first grade reading achievement and to determine whether significant differences in haptic function existed among defined subgroups of first grade subjects. Ninety-nine subjects, stratified by both sex and risk of failure (a combination of reading…

First-, third-, and fifth-grade children and adults performed a tactile shape-discrimination task. Changes in the magnitude of differences between performance in the left and right perceptual fields were examined. Results suggested that the right hemisphere becomes progressively more specialized for tactile spatial ability with increasing age.…
