Perception involves sensation, organization, interpretation, and categorization of inputs based on past experiences. It occurs quickly in the brain and is influenced by education, intelligence, and preconceived notions. Different types of perception are possible through the nervous system and each characteristic is a physical process and subjective experience.
The characteristics of perception are the sensation, organization, interpretation and categorization of inputs according to past experiences. The process of sensory perception occurs very quickly in the human brain, usually in less than a second. Different types of perception are possible through the complex activity of the nervous system receiving input from each of the five senses. This input then converts into signals that travel to the brain via the spinal cord and peripheral nervous system. Each of the characteristics of perception is both a physical process and a subjective experience according to different personalities, biases and backgrounds.
Sensation is a main feature of perception as it relates to external input. Auditory perception occurs when the ears detect sounds and carry this perceptual information to the brain. Organization occurs when listeners identify the type of sound and compare it to other sounds they have heard in the past. Interpretation and categorization are generally the more subjective areas of perception, as they involve decisions about whether listeners like what they hear and whether they want to continue listening. All of these choices are made in fractions of a second and can happen hundreds of times a day with many types of sensory input.
The process of visual perception follows the same principles as those of auditory perception. Input reaching the brain through the eyes is an important part of how people make sense of the world around them. Psychologists who study the characteristics of perception often report that people form a complete picture of reality as they see it, rather than a completely objective view. The sections of their brain dedicated to perceptual skills draw comparisons between current and past sensory input. These sets of brain cells are also responsible for forming questions and drawing conclusions based on current levels of understanding.
Factors influencing perception can include existing education levels, intelligence, and preconceived notions about certain topics. When people interpret sensory input, they typically form ideas that can be considered farsighted or nearsighted depending on previous familiarity and experience with similar types of input. This feature of perception is related to the learning process. When people study a lot about a topic very carefully, their subsequent interpretation and categorization of that topic can change as they encounter new related input. This type of learning experience is considered instrumental when it comes to honing subjective perceptual skills.
