I watched a documentary on youtube about a blind boy who sees with sound. He clicks his tongue, and listens to the sound it makes to visualize the world around him. With this unique skill he can function almost as well as anybody else. He can walk around without bumping into anything, go to school, play basketball, play video games, roller blade, and even ride a bike. The clicks he makes with his tongue bounce off near by objects and come back to him, so he can visualize how far away things are and where they are. He is the only boy in the world who sees using echo location.
The psychology of Perception involves the interaction of our senses and our conscious mind. Perception is involved in every aspect of our lives as we make decisions and judgments based on what we experience. If you study diligently you will leave this course with a broad understanding of sensation and perception. From this general understanding you will be able to further investigate areas of interest by means of literature review and research on specific topics.
