(1) When the stimulus intensity is high, the contrast is obvious and the color is bright, it is easy to become the object of perception.

Stimulators with strong light, loud sound and well-defined outline are easy to be perceived and processed. On the contrary, stimuli with dim light, weak voice and vague outline are not easy to be perceived.

(2) When the stimulus is close, continuous or similar in shape in space, it is easy to become the object of perception.

In line with the principle of perceptual organization, when other conditions are the same, stimuli that are adjacent or close to each other in space, or stimuli with continuity and similar stimuli in the field of vision, are easy to form graphics and stand out from the background and be processed and processed by perception.

(3) The stimulus conforms to the principle of "good graphics", that is, when the graphics are simple and symmetrical, they are easy to become the objects of perception.

In the field of vision, symmetrical parts, parts with good continuity, parts with simple structure, etc. are easily organized into graphics and become perceptual objects.

(4) When the stimulus contour is closed or tends to be closed, it is easy to become the object of perception.

2. The part that is closed or tends to be closed in the field of vision is easy to be organized into graphics and become the object of perception, which conforms to the closed principle of perceptual organization.

3. Perceptual selectivity is influenced by subjective factors.

4. People's perceptual selectivity depends not only on the physical characteristics of objective stimuli, but also on subjective factors such as the needs and motives, interests and hobbies, goals and tasks, existing knowledge and experience, and the meaning of stimuli to individuals.

Extended data:

Examples of perceptual wholeness:

The experimenter first presents a picture to the subject, which shows a man wearing a sportswear and running, so that people can conclude that he is a football player who is exercising on the court. Then the subjects were presented with a second picture. In front of the football player, there was a girl who ran away in panic. At this time, it was judged that a bad guy was chasing a girl.

Finally, the experimenter took out the third picture. Behind two running pedestrians, it was a lion that had just escaped from the zoo. At this time, the subjects understood the real meaning of the picture: athletes and young girls ran desperately to avoid the lion. It can be seen that without the overall situation and the relationship between the parts, the part loses its definite meaning.
