3 experiments were performed to measure the possible effect of bilateral kinesthetic difference (BKD) on tactual-kinesthetic judgment of size when the stimulus objects were simultaneously presented to the right and left hands for comparison. A BKD was not demonstrated.

The essential requisites for successful operative treatment of hands affected by rheumatoid arthritis are a thorough knowledge of the disease and experience in the applicable specialized hand surgical techniques. In musicians, decisions about the indications for surgery, the particular technique to be used, and the disadvantages of each possible procedure require additional basic knowledge about musical instruments and how they are played. This paper provides an overview of the changes in the hand and their effects on musicians in the early stages and late stages of rheumatoid arthritis as well as the special considerations that must be taken into account for operative therapy in both the early and late stages of the disease. The choice of operative procedure is often dependent on the instrument played and may vary between the right and left hands, or even from one finger to the next. If at all possible, the anticipated results of an operation should be simulated and checked preoperatively by using static or dynamic testsplints.

10 boys and 10 girls were tested at each of six age levels (6, 7, 8, 12, 13, and 14 yr.). All of the children were right-handed, and at each age level the groups did not differ in age, WISC Full Scale IQ, or educational attainment. The groups were compared on motor tasks (strength and speed) and tactile-perceptual tasks (finger localization and symbol recognition). The performances of the right and left hands were compared. The results indicated clear right-hand motor superiority, but no “sidedness” effect for the tactile-perceptual measures. The implication of these results for brain-behaviour relationships was discussed.

The present study investigated the effects of the use of the right and left hands on haptic identification of letters of the alphabet. Each of the 64 right-handed subjects was given three series of randomly ordered presentations of the 26 letters of the alphabet. The subjects were asked to feel each letter and name correctly each letter as quickly but as accurately as possible. Analysis showed faster identification by those subjects using their left hands on Series 1 with no hand-differences appearing on Series 2 and 3. Significant over-all improvement in identification time occured with practice. The results were interpreted in terms of a novelty hypothesis of right-hemisphere function and an explanation of perceptual learning of letter identification.

Right And Left Hands

Congenitally blind and sighted blindfolded children between the ages of 6 and 14 years were tested for hand preference with performance tasks. There were no differences between the groups in direction or degree of hand preference. The degree of handedness increased with age and was essentially linear though the blind seemed to be somewhat less lateralized at the younger ages. When the same groups were required to match three-dimensional bricks for height, depth, breadth, and volume, no hand advantages were found for either group. Both groups of children improved in their accuracy of spatial discriminations with age. Further, the degree of lateralization on the handedness task did not relate to ability on the tactile task or to differences between the right and left hands on the tactile task. Thus, there is no effect of blindness on tactile matching ability nor is there an effect of the hand used in the task.

Here we report an experiment in which 16 right-handed young adults named a series of unilaterally presented pictures during concurrent unimanual finger tapping with the right and left hands at separate times. A multivariate analysis of variance showed no significant differences in picture-naming reaction time between left versus right visual-field stimulations. Also the test for finger tapping was nonsignificant, with the magnitude of disruption being symmetrical for the right and left hands as a function of visual fields. It was proposed that the two cerebral hemispheres interact with each other at later processing stages when performing tasks requiring both left and right hemispheric processing resources.

Lateralization of peripheral nerve conduction velocity was studied in right-handed men ( n = 40) and women ( n = 48). Sensory and motor velocities were measured in ulnar and median nerves of the right and left hands. In women, the mean sensory velocity was significantly faster in the left than the right hand. There were no significant right-left differences in men. The mean sensory velocity from the right hand was significantly slower in women than men, creating an asymmetric organization of sensory conduction in women. Estradiol in women and testosterone in men were suggested as playing a role in asymmetric and symmetric nerve conductions, respectively.
