The main difference between sensation and perception lies in the processes they involve and their purpose. Sensation is the physical process by which our sensory receptors detect sensory stimuli from the outside world. Examples of sensory receptors include the taste buds on your tongue, the auditory receptors in your ears, and the light-sensitive cells in your eyes. In essence, sensation is the act of detecting something using our five senses. Perception, on the other hand, is the psychological process by which the brain organizes, interprets, and consciously experiences these sensations. It involves creating meaningful information about the stimuli in our surroundings. Perception is influenced by factors such as beliefs, values, prejudices, and past experiences. In summary, sensation is the act of detecting stimuli using our sensory receptors, while perception is the process by which our brain interprets and gives meaning to these sensations. One way to think of this concept is that sensation is a physical process, whereas perception is psychological. Some examples to illustrate the difference between sensation and perception: Sensation: Light entering the eye causes chemical changes in cells that line the back of the eye, which then relay messages to the brain.
Perception: Interpreting the light as a visual image, such as the word you are reading right now.
Sensation: Detecting the scent of baking cinnamon rolls with your olfactory receptors.
Perception: Associating the scent with the memory of your grandmother's baking or anticipating the enjoyment of eating the cinnamon roll.
Sensation: Hearing an alarm going off.
Perception: Recognizing the sound as an alarm and interpreting it as a signal to wake up or take action.
