Perception is defined as the mental process of organizing sensations into meaningful patterns. Moreover, Perception is the process of "knowing" which depends on intact sensation; mental experience that occurs when sensations are given meaning by the memory of past experiences. According to Helmholtz, Perception is the mental experience arising when sensations are embellished by the recollection of past experiences.

Perception is the process by which the brain organizes and interprets sensory information from the environment. It refers to the way we interpret and make sense of what we see, hear, touch, taste and smell. Perception is a complex process that involves several different stages, including sensation, attention, and interpretation.

For example, when looking at a tree, you first see the tree and then you perceive the tree's shape, size, texture, and color. Your perception of the tree is influenced by past experiences and expectations, as well as the context in which the tree is seen.

Perception can also be affected by cognitive processes such as attention, memory, and expectations. For example, a person may not perceive an object in their peripheral vision if they are not paying attention to it, or they may perceive an object differently if they have prior knowledge of it.

Perception can also be affected by cognitive biases, such as selective attention and confirmation bias. For example, a person may perceive a neutral face as angry if they are in a negative mood or have had a bad experience with the person before.

It's worth noting that perception is not a direct representation of reality but an interpretation of it, and it can be influenced by a person's past experiences, emotions, and cognitive biases.
