Discuss key features on perceptual development
Answers
Perception involves many attributes, but the three most recognized features of perception include constancy, grouping (particularly the Gestalt principles), and contrast effect.
Constancy
In terms of perception, constancy refers to the capability of one or more perceptual systems to identify the same object among a sea of sensory inputs. For example, a coin looks circular when held face-on, and elliptical when it is held showing its side. But, constancy enables us to identify the object as a coin even if it is held either way. Without constancy, we might perceive one object as a different sensory input if sensed in a different angle, degree, intensity or frequency.
Grouping
Grouping is a feature of perception that follows the principles primarily proposed by Gestalt psychologists. The principles of grouping were formulated to analyze the natural human perception of objects as organized and in patterns. The six Gestalt grouping principles include proximity, similarity, closure, good continuation, common fate, and good form. Learn more about them here.
Contrast Effect
A contrast effect refers to the increase or decrease in perception as related to the normal intensity, degree, frequency or other attributes. The so-called "normal perception" is based on the previous experience/s of the person.
Answer:
Perception is the process of taking in the information, organizing and interpreting it.
And when the child develops motor competence, they make use f perceptual information to inform their choices about the motor actions.
Key features of perceptual development :
Constancy- identifying the same objects from a group of a number of sensory inputs.
Grouping- Organizing things in certain pattern
Contrast- increase and decares in perception.
