Difference between Sensation and Perception

The sensory-perceptual process can be divided into different stages. It always starts with a stimulus, which becomes a sensation and later a perception.

Thanks to sensation and perception, mental constructions such as smells, colors, flavors and others allow us to create the world we know. Without an organism and an organ capable of processing and interpreting them, it can be said that these stimuli would not exist. For example, time is a construction created by man as a way to measure the continuity between his actions. Without the human species, time would only exist as the changes that things and beings experience throughout their lives.

Sensation
Perception
Definition It is the reception of stimuli that occurs thanks to the sensory organs (smell, taste, sight, touch and hearing). They are immediate basic experiences that are usually generated by simple stimuli. These stimuli are transformed into electrical and/or chemical impulses that travel to the nervous system or the brain where they are transformed into perceptions. It can be said that it is the interpretation of sensory stimuli (sensations). It is the part of the sensory-perceptive process in which sensations are given meaning and are organized and integrated. Perception is individual, so the processing of stimuli is different for each person. The same stimulus will not be perceived in the same way by two people.
examples A determined person can feel a change in the aroma of the environment. This change in scent is perceived as a specific perfume or scent, for example, the perfume that this person’s mother wears.
