OVERVIEW
This page is used to organize CRG work on clinical findings and observable entities related to perception and sensation.
MAJOR FUNCTIONS, PROCESSES, STATES, QUALITIES AND DISPOSITIONS
Major Concepts | Type of phenomenon | Commonly Used Terms | SNOMED CRG Working Definition |
---|---|---|---|
Perception function | Function | perception, mental model, image | Perception is a function that endows a person with the capacity to mentally represent internal and external stimuli detected by sensory organs. The realization of this function is the mental representation of the detected stimulus. The inputs to the perception function are typically the outputs of a sensory process. However, perception sometimes occurs in the absence of any sensory stimulus, for example, in hallucination. Note: (see URU discussion) |
Perceptual process | Process | perceiving | The perception process is the process by which sensory outputs (signal generated by a real or imagined sensory stimulus) are transformed to produce both a mental representation and phenomenological experience of the stimulus. At the physical level, the perception process is instantiated by the perception function - the set of anatomic structures, physiological processes, and rules governing physiological processes that initiate, perform, sustain, and terminate the conversion of sensory outputs to a perceptual experience (i.e., the perception function). |
Perceptual experience | State | a perception, a sensation, a sight, a sound, a smell, a taste, a touch (sensation) | A perception experience is the |
Sensory function | Function | sensation, sensory transduction | |
Sensory process | Process | sensory transduction process | |
Sensory experience | State | a sensation, a sensory experience | |
Sensory perception function | Function | Sensory perception is a function that endows a person with the capacity to detect internal and external stimuli via sensory transducer structures in the body and transmit this information to the brain (sensory function), then cognitively represent, organize, and interpret this information (perception function). The realization of the sensory perception function is the acquisition of information from stimuli both within the body and the external environment. | |

DEFINITIONS
Term | Source | Definition |
---|---|---|
Sensation | Accessed | sensationn.1. the process or experience of perceiving through the senses. See sensory system. 2. an irreducible unit of experience produced by stimulation of a sensory receptor and the resultant activation of a specific brain center, producing basic awareness of a sound, odor, color, shape, or taste or of temperature, pressure, pain, muscular tension, position of the body, or change in the internal organs associated with such processes as hunger, thirst, nausea, and sexual excitement. Also called sense datum; sense impression; sensum. |
Perception | Accessed | perceptionn. the process or result of becoming aware of objects, relationships, and events by means of the senses, which includes such activities as recognizing, observing, and discriminating. These activities enable organisms to organize and interpret the stimuli received into meaningful knowledge and to act in a coordinated manner. |
