Feeling is the basis of all psychological activities. Only after things are felt can things be perceived and thought on this basis. Sensation is inseparable from perception and all other psychological activities, especially since it is closely related to perception. Sensation and perception are two inseparable basic psychological processes.
(a) Similarities between perception and perception.
From the definition of sensation and perception, we can see that the objects reflected by both are the surface phenomena of objective things, and the impressions formed in people's minds are the concrete images of objective things, and the process of gaining sensory experience.
From the perspective of the two ways of reflecting objective things, they are both direct reflections of objective things. Only when objective things directly act on the sensory organs, will sensation and perception be produced. When things disappear, sensation and perception will also disappear. Since both belong to the sensory cognition stage, sensory perception is commonly referred to as perception.
(II) The difference between sensation and perception
As two different levels of psychological processes, there are certain differences.
1. The source of the production is different. Sensation is an activity between psychology and physiology, a simple psychological process based on physiological effects. Its production mainly comes from the physiological activities of sensory organs and the physical characteristics of objective stimulation. Sensation is a common phenomenon shared by individuals; while perception is pure psychological activity, a psychological activity process that comprehensively and explains various attributes of objective things based on sensation, reflecting the participation of human knowledge and experience and subjective factors.
Like the same stimulation, it can cause the same sensation, but it will cause different perceptions. Experience plays different roles in the activities of sensation and perception. Whether a person's feelings can be produced or not. Experience can make the sensitivity more sensitive, but the generation of perception cannot be separated from experience. It relies more on the individual's knowledge and experience and personality characteristics.
2. The specific content reflected is different. Feeling is the reflection of the individual attributes of objective things by the human brain, while perception is the comprehensive and overall reflection of the various attributes of objective things.
3. Different physiological mechanisms. Sensation is the result of a single analyzer activity, and perception is the result of analyzing and combining the relationship between complex stimuli or stimuli in a synergistic manner in multiple analyzers.
4. Perception is a psychological activity higher than sensation, but it is not a simple sum of feelings. It is generated under the influence of individual knowledge and experience, as well as the psychological characteristics of , such as needs, motivation, interests, emotional states, etc., and perception is greater than the sum of feelings.
(III) The connection between sensation and perception
Sensation is the basis for the generation of perception. Sensation is an organic part of perception and a basic condition for the generation of perception. Without a feeling of reacting to the individual attributes of objective things, it is impossible to have a perception that reflects the overall objective things. The correctness of perception depends on the correctness and integrity of perception. For example, the story of "The Blind Man Touching Elephant" illustrates this point. As a result, each blind man's single feeling is correct, but because of the lack of completeness of the feeling, the perception of the elephant is wrong.
2. Perception is the in-depth and development of sensation, which in turn affects the refinement of sensation.
3. Sensation and perception are carried out simultaneously. In real life, people rarely have isolated feelings. Usually the two are integrated. In psychology, they distinguish feelings from perception and discuss them only for the needs of research.
