Piaget's "animism" is characterized by the pre operational stage
The main features of the pre operation stage are as follows:(1) animism
children can't distinguish between living and inanimate things, and often extend people's conscious motivation and intention to inanimate things
(2) egocentrism
children lack the ability of opinion selection, they only view the world from their own point of view, and it is difficult to understand the views of others
(3) the irreversibility of thinking
children can't mentally reflect on the behavior they see, and can't recall what things looked like before they changed
(4) lack of conservation
children do not realize that when the surface features of things change, their essential features do not change. Nonconservation is an important feature of pre operational children
Piaget believes that in the process of indivial development from birth to maturity, cognitive structure is constantly reconstructed in the interaction with the environment, thus showing different stages of homogeneity. He divides the development of children's thinking into the following four stages:
1, perceptual motor stage (0-2 years old)
this stage, Children have two great achievements in cognition: they have acquired the permanence of objects, that is, they have lost the consciousness of perceiving objects and still believe that they exist continuously; There is a causal relationship
It can be divided into two stages: pre concept or symbolic thinking stage (2-7 years old) and intuitive thinking stage (4-7 years old) There are two remarkable characteristics in the stage of concrete operation (7-12 years old)this stage has: the conservation and reversibility of thinking, that is, they can think about the changes they see in reverse and compare them before and after, and think about how the changes occur; The formation of group structure can classify objects according to the complex rules of combining various characteristics
In this stage, we can use language to imagine and think in the mind, reconstruct things and processes to solve problems. In addition, according to the concept, hypothesis and so on as the premise, the hypothesis dection reasoning, draw a conclusion. Therefore, whether a child has the ability of hypothetical dection is an extremely important measure to judge his intelligence1. Delete unnecessary data and applications: Intelligent Manager (memory manager) - storage space / memory
2. Close unnecessary applications: click the recent task key in the lower left corner of the screen - click "X" in the upper right corner of the application to be closed / close all in the lower right corner
3. If the mobile phone supports memory card, move the multimedia files to the expansion card or set the shooting storage path to the expansion card. If there is no memory card, it is recommended to move multimedia files to the computer regularly
4. Uninstall infrequently used software or files
if the memory of the mobile phone is still insufficient after the above operation, it is recommended to back up the data (contacts, information, photos, etc.) in the mobile phone and try to restore the factory settings.
