Perception and Perceptual Training Activities

At my hospital something in the region of a 1,000 head injuries are admitted each year. The task of rehabilitating the severe ones with all their disturbing problems becomes an ever-increasing worry. There is no denying that treatment time spent on these patients is one of the most expensive in terms of manpower for their learning patterns may take months and even years to re-establish, some perhaps not at all. Nevertheless, we do have a duty to bring them to as good a quality oflife as possible, and then hope that time and nature will do the rest. Each of you receives your head injury patients at various stages of recovery; some come to you at the later stages of their rehabilitation and it does not take you long to discover that your patient is heartily fed up not only with himself but every therapist he sets eyes upon. You are therefore familiar with the head injury cases who display the most bizarre and meaningless behaviour; who are distractable, inattentive, and emotionally charged at the least provocation or the ones who apathetically sit and wait for the next meal. I am not going to suggest that a knowledge of perception and a programme of perceptual training activities are the answer to all your prayers; far from it, there are too many variables. But consideration of perception may be a step forward in the understanding as to why these patients behave as they do. First, let us establish what we mean by perception. It has been described in many ways. I am going to quote the definition from Chambers Encyclopaedia:
