The ability quickly and accurately to recognize similarities and differences among presented objects, whether these be pairs of words, pairs of number series, or multiple sets of these or other symbols such as geometric figures.
Mental processes by which intellectual, sensory, and emotional data are organized logically or meaningfully.
The intermediate level of contact with the internal or external environments. The perceptual area of the brain interprets the impulse as sight, sound taste, smell, or bodily sensation; however, other impulses may be generated and transmitted to other areas of the brain for significance, relationships, and action. What we perceive is not so much dependent upon the sense organ that is stimulated as it is upon the area of the brain that is stimulated.
An impression formed in the brain as a result of information about the outside world which is passed back by the senses.
Process by which information received by the senses is recognized, interpreted, and analyzed to become meaningful.
The process by which the body collects and analyzes information about the world. Perception consists of the conscious recognition and interpretation of sensory stimuli. It is the vehicle through which people know, understand, learn, or process data in order to make conscious or unconscious decisions about actions and reactions.
The process by which information about the world, received by the senses, is analyzed and made meaningful. Abnormalities of perception include hallucinations, illusions, and agnosia.
Perception is the process of comprehending a sensation. The brain receives input from the five senses (taste, smell, hearing, vision, and touch), which it then recognizes and arranges into a meaningful pattern. Various factors like attitude, mood, and expectations influence the ultimate interpretation. For instance, an individual who is hungry will likely pay more attention to the sight and aroma of food compared to someone who has recently eaten.
Hallucinations are erroneous perceptions that manifest without the presence of sensory input.
