Are you familiar with Piaget’s stages of cognitive development? Piaget created four stages of development. He was able to justify that all children go through these four stages, but at different rates. Throughout this paper, I will discuss the four general periods of development. First, piaget developed sensorimotor intelligence period. Stage one(birth to one month) uses schemes and reflexes. For example, infants suck whenever their lip are touched. Stage two (one to four months) deals with the the primary circular reactions. A prime example of circular reaction is thumb-sucking. Stage three (four to eight months) use secondary circular reactions. Stage four(eight to twelve months) deals with the coordination of secondary schemes. Stage five (twelve to eighteen months) uses tertiary circular reactions . Stage six ( eighteen to two years) deals with children being able to vary their reactions and observe the results. Second, the child undergoes the preoperational stage between the age of two and seven. During this period, a child begins to use symbols to represent a missing object. The use of symbols is most vital in make-believe play. Also, …show more content…

During this period, children gain the knowledge of conservation ( liquids, numbers, weight, volume, and length) . The conservation of liquid is Piaget’s most famous experiment. The child is shown two glasses that are filled with water to the same height. Immediately, the child agrees that both glasses are the same. The experimenter pours one of the glasses of water into a taller glass, and proceeds to question the amount once more. The child explains that the taller glass has more because it is bigger. The child’s response is incorrect. The correct response should have been that the amount is still the same. By doing this experiment with a child, it allows the experimenter to know that the child has not mastered conservation
