• • • Perception (from the perceptio) is the organization, identification, and interpretation of in order to represent and understand the presented information, or the environment. All perception involves signals that go through the, which in turn result from physical or chemical stimulation of the sensory system. For example, vision involves striking the of the eye, smell is mediated by, and hearing involves. Perception is not only the passive receipt of these signals, but it's also shaped by the recipient's,,, and. Perception can be split into two processes, (1) processing the sensory input, which transforms these low-level information to higher-level information (e.g., extracts shapes for object recognition), (2) processing which is connected with a person's concepts and expectations (or knowledge) and selective mechanisms () that influence perception.

Perception depends on complex functions of the nervous system, but subjectively seems mostly effortless because this processing happens outside conscious awareness. Since the rise of in the 19th Century, has progressed by combining a variety of techniques. Quantitatively describes the relationships between the physical qualities of the sensory input and perception. Studies the brain mechanisms underlying perception.

Include the extent to which sensory qualities such as sound, smell or color exist in objective reality rather than in the mind of the perceiver. Although the senses were traditionally viewed as passive receptors, the study of and has demonstrated that the brain's perceptual systems actively and pre-consciously attempt to make sense of their input.

There is still active debate about the extent to which perception is an active process of testing, analogous to, or whether realistic sensory information is rich enough to make this process unnecessary. The of the enable individuals to see the world around them as stable, even though the sensory information is typically incomplete and rapidly varying.

Human and animal brains are structured in a, with different areas processing different kinds of sensory information. Some of these modules take the form of, mapping some aspect of the world across part of the brain's surface.

These different modules are interconnected and influence each other. For instance, taste is strongly influenced by smell.
