Many adults continue to manifest these problems. The four year olds show reversals as they put on shoes by themselves. Some four to five year olds may start printing numbers and letters from right to left. At these ages, this is a normal stage of developing orientation in children. Although most children master this concept of directionality by age seven, this confusion in orientation may continue, in some people, all their life.
Reversals are a manifestation of a developmental lag in the process or orientation.
They are indicative of an underlying problem in the integration of the vestibular and visual systems in the brain. Rote repetition of learning to write letters and numbers correctly or rotely learning right and left hands may help us pass a test, but it does not solve the problem of the underlying causative factor of orientation development. The development of orientation starts in the prenatal period with the attitudinal reflexes which help the fetus orient in utero. This development continues through varied learned experiences in our lives. Interference in movement activities involving vision and neuromotor relationships limit the development of orientation.
