Perceptual set

Explanation:

The perceptual process to the objects higher in our field of vision as the closer. it involves selection, inferences, and interpretation. It is more important in the active process. It is a process in which notice some aspects of perceptual data and ignore others. the factors that affect our perceptual tendencies are motivation, emotions, expectation, and culture. Sometimes it is helpful .It is a good example of top-down processing. Schema, mental framework, and concepts often guide the perceptual guide.
