Our current project studies hemispheric specialization in stereognosis, the ability to blindly use manual information to identify novel objects, using 3-D printed cylinders of successive size (1 mm to 16 mm diameter). Our preliminary results in right-handers indicate a right-hand advantage for stereognosis, consistent with left-hemisphere specialization for proprioceptive-visual integration. We also explored interlimb transfer in this task. Following opposite arm experience with the task, the left arm improved compared to left arm naive performance, while the right arm showed a decrement in compared to right arm naive performance. These findings not only confirm a right arm advantage for this task, but also suggest competitive interhemispheric influences on this task.
