In everyday language, the terms "sensation" and "perception' are often usedinterchangeably.SENSATION:Sensations can be defined asthe passive process of bringing information from the outside worldinto the body and to the brain.The process is passive in the sense that we do not have to beconsciously engaging in a "sensing" process.Sensation occurs:a) sensory organs absorb energy from a physical stimulus in the environment.b) sensory receptors convert this energy into neural impulses and send them to the brain.
In other words, Sensation is the process by which our senses gather information and send it to thebrain.A large amount of information is being sensed at any one time such as room temperature,brightness of the lights, someone talking, a distant train, or the smell of perfume.With all thisinformation coming into our senses, the majority of our world never gets recognized.We don'tnotice radio waves, x-rays, or the microscopic parasites crawling on our skin.We don't sense allthe odors around us or taste every individual spice in our gourmet dinner.We only sense thosethings we are able too since we don't have the sense of smell like a bloodhound or the sense ofsight like a hawk; our thresholds are different from these animals and often even from eachother.PERCEPTION:Perception can be defined asthe active process of selecting, organizing, and interpreting theinformation brought to the brain by the senses.Perception follows:a) the brain organizes the information and translates it into something meaningful.The perceptual process allows us to experience the world around us. Take a moment to think ofall the things you perceive on a daily basis. At any given moment, you might see familiar objectsin your environment, feel the touch of objects and people against your skin, smell the aroma of ahome-cooked meal and hear the sound of music playing in your next door neighbor's apartment.All of these things help make up our conscious experience and allow us to interact with thepeople and objects around us.In this overview of perception and the perceptual process, we will learn more about how we gofrom detecting stimuli in the environment to actually taking action based on that information.What Is Perception?Perception is our sensory experience of the world around us and involves both the recognition ofenvironmental stimuli and actions in response to these stimuli. Through the perceptual process,we gain information about properties and elements of the environment that are critical to oursurvival. Perception not only creates our experience of the world around us; it allows us to actwithin our environment.
