Perception is the process of getting, interpreting, selecting, and organizing sensory information. Perception usually deals with the human senses that generate signals from the environment through sight, hearing, touch, smell and taste.
In other words, perception is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system.
Humans have five basic senses: touch, sight, hearing, smell and taste. The sensing organs associated with each sense send information to the brain to help us understand and perceive the world around us. Sensory perception is often the most striking proof of something factual—when we perceive something, we interpret it and take it as “objective” or “real”. Most obviously, we can experience this with eyewitness testimonies.
Perceptual illusions can be seen, interpreted and used in two very different aspects: on the one hand, and this is the common property assigned to illusions, they are used to entertain people. They are a part of everyday culture; they can kill time. On the other hand, they are often the starting point for creating insights.
Perception is the key to gaining information and understanding the world around us. Without it, we would not be able to survive in this world filled with stimuli surrounding us. This is because perceptions not only mould our experience of the world but allows us to act properly within our environment.
When individuals have a preconceived perception about a given person or situation it will result in the reality of their expectation. Identifying and understanding the way the brain processes information through our senses is one of the most beneficial tools of the cognitive mind.
