Perception (from Latin perceptio 'gathering, receiving') is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. [2]
Commonly recognized sensory systems are those for vision, hearing, touch, taste, smell, balance and visceral sensation. Sense organs are transducers that convert data from the outer physical world to the realm of the mind where people interpret the information, creating their perception of the world around them. [1]
For example, the general sensation and perception of touch, which is known as somatosensation, can be separated into light pressure, deep pressure, vibration, itch, pain, temperature, or hair movement, while the general sensation and perception of taste can be separated into submodalities of sweet, salty, sour, bitter, spicy, and umami, all of ...
Vision dominates our perception of the world around us. This is because visual spatial information is one of the most reliable sensory modalities. Visual stimuli are recorded directly onto the retina, and there are few, if any, external distortions that provide incorrect information to the brain about the true location of an object. [18]
What is considered a strange blurring of sensation from one perspective, is a normal and 'natural' way of perception of the world in another, and indeed many individuals and their cultures develop sensoria fundamentally different from the vision-centric modality of most Western science and culture. One revealing contrast is the thought of a ...
Flavor perception is an aggregation of auditory, taste, haptic, and smell sensory information. [18] Retronasal smell plays the biggest role in the sensation of flavor. During the process of mastication , the tongue manipulates food to release odorants.
Visual perception is the ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment. The resulting perception is also known as visual perception, eyesight, sight, or vision (adjectival form: visual, optical, or ocular). The various physiological components involved in vision ...
Patients undergoing regional anesthesia can have incorrect, "phantom" perception of their limb positions during a procedure. A longstanding neurological explanation of this effect was that, without incoming signals from proprioceptive neurons, the limb perception system presented to consciousness a default, slightly flexed position, considered ...
