Sensation and Perception As It Relates to Human Processing
Although well related, sensation and perception play two complimentary but vastly different roles in how we interpret our world as humans. Sensation refers to the process of sensing our environment through touch, taste, sight, sound, and smell, also known as the five senses. This information is then sent to our brains in raw form where perception comes into play. Perception is the way we interpret sensations and then make sense of everything surrounding us. Both sensation and perception are simply two terms used to describe how our senses work coherently together to organize and interpret information. Although sensation and perception are used conjointly in processing the world around us, they each have individual processes that together piece together our world almost as you would a jig-saw puzzle. Sensation is the process in which our senses gather information and send it to our brain. A copious amount of information is being taken in at a time such as smells, temperatures, sounds, and images. Even with all of the information our brain takes in, a lot of information is not being processed such as various waves and microscopic images our brain is yet to learn how to process. To date we are not able to smell every single smell in our vicinity or hear every minute sound, we focus on a set or even an individual sense. As humans our thresholds are different. We possess an absolute and difference threshold. The absolute threshold is the point where something becomes noticeable to our senses. It is the most solemn sound we can hear or the slightest touch we can feel. Anything less than this goes unnoticed to us. The absolute threshold is the point at which a stimuli goes from undetectable to detectable to our senses. While the absolute threshold is a useful concept, it does not exist in reality. That is, on one occasion, an individual might...
