We're familiar with left-brain/right-brain functions & being left or right handed, but we also have a dominant eye, ear, and foot. The experiences and research from Dr. Carla Hannaford's book, The Dominance Factor, shed some surprising light (for us) on how our dominant sensory and motor functions may affect us under stress or new learning situations--which is pretty much the conditions our children are in all the time. This is just one more factor to consider for parents to "know their child."
