Decentralization is Piaget's stage
the first stage is sensory motor stage. From birth to about 2 years old, children in this stage can only rely on their own muscle movements and senses to cope with external things. This stage is further divided into six small stages: ① from birth to 1 month, At this time, the baby's movements become more coordinated, but it can't play with foreign objects. At this time, the baby's movements become more coordinated, but it can't play with foreign objects, The baby's vision is coordinated with grasping. It begins to fiddle with things around it. The 10 month old baby knows that things still exist when they are out of sight. ④ 10-12 months old. At this time, the behavior has a purpose, and it begins to be able to predict the effect of the behavior. ⑤ 12-18 months old. The baby will do slightly different actions for different objects to see what the results will be. ⑥ 18-24 months old, The second stage is the pre operation stage, which is about 2-7 years old. In this stage, children can only think with representation, and their thinking is superficial, primitive and chaotic. The pre operation stage can be divided into two stages: ① pre concept stage, about 2-4 years old. This stage is characterized by the emergence of symbolic function and imitation. ② intuitive thinking stage, the pre operation stage is divided into two stages, About 4-7 years old. Young children mainly reflect the surface phenomenon of things, only push from one special situation to another special situation, and describe irrelevant things as causality. Egocentrism is the prominent feature of this stage.
the third stage is the concrete operation stage. About 7-11 years old, in this stage, children form a preliminary operation structure, At this stage, children develop "decentralization", that is to say, the self-centered idea of only looking at problems from their own point of view graally disappears. At this time, children can not only focus on one aspect of the situation or problems, We can also pay attention to several aspects; We can not only pay attention to the static state of things, but also see the dynamic change; It can also reverse the direction of thinking.
the fourth stage is the stage of formal operation. From about 11 to 12 years old, the indivial has formed a complete cognitive structure system, can carry out formal propositional thinking, and the intellectual development tends to be mature. Piaget initially thought that the intellectual development of formal operation was completed at about 15 years old. Later, he revised his original view in 1972, It is considered that normal people should reach the stage of formal operation no later than 15-20 years old
2. Pre operation stage (2-7 years old). At this time, the child has not yet established the real logical operation ability, can only learn the preliminary metaphysical cognition, so it often shows the self-centered way of thinking. Piaget's "three mountains experiment" is to verify the characteristics of self cognition in this stage
3. Specific operation stage (7-12 years old). At this time, children began to establish specific logical thinking ability, and began to learn to analyze things rationally. But we can't think logically out of the physical objects completely, so the thinking at this time is more abstract than image thinking. This is also the reason why primary school teachers often need to give examples in kind in class, and their examination questions are often applied
4. Formal operation stage (over 12 years old). At this time, children began to learn abstract operations, and they could do logical thinking without physical objects. They learned to enter the thinking mode of alts. However, there are many people who can not enter the stage of formal operation in their life, but can only stay in the stage of concrete thinking, which is often manifested in the lack of logical reasoning ability and spatial imagination ability. According to gender differences, psychological research tends to be mostly female
it should be noted that Piaget's cognitive development theory is a longitudinal description of human cognitive development process from the perspective of developmental psychology. However, to really understand the essence of Geneva School, we need to combine it with his other horizontal cognitive theory "genetic epistemology" to understand Piaget's point of view.
He divided cognitive development into four stages: sensorimotor stage, pre operation stage, specific operation stage and formal operation stage. The four stages are as follows:
the first stage is sensorimotor stage. From birth to about 2 years old. This stage of children can only rely on their own muscle movements and feelings to deal with external things. This stage is further divided into six stages:
① from birth to 1 month. At this time, the baby is not aware of the things around, or even their own existence, can not distinguish between things and me, lack of self-awareness
(2) 1-4 months. At this time, the baby's movements become more coordinated, but still can not play with foreign objects (3) 4-10 months. At this point, the baby's vision and grasping movements are coordinated. I started fiddling with things around me. Infants aged 9 to 10 months know that things are still out of their sight (4) 10-12 months. At this point, the behavior has a purpose, and the effect of the behavior can be expected (5) 12-18 months. The baby will make slightly different movements to different objects to see what the results will be (6) 18-24 months. Before acting, babies can think about actions in their minds and find new ways to solve problems The second stage is the pre operation stage. About 2-7 years old. In this period, children can only think by appearance, their thinking is superficial, primitive and chaotic. The pre operation stage can be divided into two stages:① pre concept stage, about 2-4 years old. This period is characterized by the appearance of symbolic function and imitation
(2) intuitive thinking stage, about 4-7 years old. Children mainly reflect on the surface phenomenon of things, only push from one special situation to another, and say irrelevant things have causality. Egocentrism is the prominent feature of this stage The third stage is the concrete operation stage. About 7-11 years old, in this stage, children formed a preliminary structure of operation, appeared logical thinking. However, thinking is also directly related to specific things, cannot do without specific experience, and lacks the ability of generalization. Abstract reasoning has not yet developed, and can not carry out propositional operationat this stage, children develop "decentralization", that is, the self-centered idea of only looking at problems from their own point of view graally disappears. At this time, children can not only focus on one aspect of the situation or problem, but also pay attention to several aspects; We can not only pay attention to the static state of things, but also see the dynamic change; It can also reverse the direction of thinking
The fourth stage is the formal operation stage. From about 11 to 12 years old, to this stage, the indivial has formed a complete cognitive structure system, can carry out formal propositional thinking, and the intellectual development tends to be mature Piaget initially thought that the intellectual development of formal operation was about 15 years old. Later, in 1972, the original view was revised, that normal people should reach the stage of formal operation no later than 15-20 years oldthe first stage is sensory motor stage. From birth to about 2 years old, children in this stage can only rely on their own muscle movements and senses to cope with external things. This stage is further divided into six small stages: ① from birth to 1 month, At this time, the baby's movements become more coordinated, but it can't play with foreign objects.
