Sensation and Preception - Essay Example Driving is another instance where sensation and perception is vital to our well-being. Determining our distance in relation to a structure, or another vehicle, is particularly important for our safety, and the safety of others with whom we share the road. These are two instances, in which these processes are necessary to ensure our survival during our normal, everyday lives. During the viewing of this video, my perception of sensory stimuli was noticeably changed on numerous occasions. The most notable of these, was the screen that appeared to be a darker shade of gray on the left half. This was most intriguing, because when the sensory stimuli was altered by simply covering the center boundary, the only area in which a difference in shade was actually present, both halves of the screen were proven to be identical in color. In retrospect, even though one is aware of there being no actual difference, aside from the center boundary, we still get the sensation that there is a slight dif ference in brightness or color. This phenomenon, referred to as subjective contours, is explained as the brain’s tendency to detect a slight difference in the sensory stimuli, in this case the slight color variation, and to over-extend that variation, therefore registering a pattern that does not exist.
