Sensation and Perception Psychology Introduction Sensation and perception play different roles in how we understand our world. In this essay I will explain the difference between sensation and perception, describe the signal detection theory and sensory adaptation and the important role they play in psychology and how we make sense of what we see, hear, taste, touch, and smell. Sensation and Perception Sensation is when our senses gather information and send it to our brain. A huge amount of information is being sensed at the same time such as taste, touch, sight, sound and smell.

There is something called the absolute threshold and this is the point where something becomes noticeable to our senses, things like sounds. There is also something called the difference threshold which is the amount of change needed for us to recognize that a change has occurred. Perception is the understanding of what we take in through our senses. It’s the way we perceive things in the environment. It’s what makes us difference from each other. The process of selecting, organizing and interpreting the information brought to the brain by the senses. The way sensation and perception work together is that sensory organs take up energy from a physical stimulus in the environment, then sensory receptors switch this energy into neural impulses and send them to the brain, as this is going on, perception comes into play, the brain organizes the information and turns it into something we can understand. During signal detection we attempt to detect what we want to focus on and ignore or not think
