This is Thor. A dog that stayed for a week at a boarding kennel that I work at. He touched my heart as soon as I laid eyes on him. He would come up for scratches with his little puppy dog eyes, but what was interesting, like most dogs, when you scratched between his shoulder blades he would shake on of his back legs. Dogs shake their back legs due to a reflex that the touch receptor in that area put off. When a prolonged signal is being sent from that area the signal is sent from there to the signal cord for processing and back through the central dorsal horn to send a motor signal telling the leg to shake. Reflexes are processed in the spinal cord.
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.
