Perceptions on the other hand, require organizing and understanding the incoming sensation information In order for sensations to be useful, we must first add meaning to those sensations, which create our perceptions of those sensations. The sensation is the initial conscious response of the brain to the stimuli or it can be understood as the first step in the direction of perception, whereas perception is the second or say direct response to the sensation and an indirect response to the physical stimulus. Sensation and perception are two separate processes that are very closely related Sensation is input about the physical world obtained by our sensory receptors, and perception is the process by which the brain selects, organizes, and interprets these sensations. Sensation provides the raw sensory data that perception relies on, while perception gives meaning and context to the sensory inputs
Perception builds upon sensation by organizing and interpreting the sensory information, allowing us to make sense of our surroundings. Our sensory receptors are constantly collecting information from the environment, however, it is how we interpret the information that affects how we interact with the world Perception refers to the way sensory information is organized, interpreted, and consciously experienced. Sensory receptors are specialized neurones that respond to specific types of stimuli When sensory information is detected by a sensory receptor, sensation has occurred For example, light that enters the eye causes chemical changes in cells that line the back of the eye.
Differences in sensation and perception can lead to phenomena such as optical illusions, where sensory input is misinterpreted. One way to think of this concept is that sensation is a physical process, whereas perception is psychological. Here, we will discuss the difference between sensation and perception, before an overview of how sensory information is received and processed by the nervous system and how that affects our conscious experience of the world.
