Piaget 's influence of the four - step theory Piaget is an influential psychologist who produced four levels of cognitive development. He believes that when humans are in infancy, childhood and adolescence, they try to understand the world through experimentation. In the process of cognitive development, children are small scientists who create theories, experiments and conclusions about how to adapt to the world. When children are adults, they will influence what they have learned and they will be able to use the skills they need to live in this world.
The developmental theory of Jean Piaget, which is one of these theories, is considered as the theory of the first stage, and Piaget itself is considered one of the most important people in developmental psychology. Piaget believes that everyone went through the same four stages. In order to move from one stage to the next stage, the goal of the current stage must be reached. This theory is widely used in the school curriculum. Erik Ericsson is interested in self-development (how humans develop self-consciousness) and personal social / cultural identity (the role played by individual families and society). Psychology His theater theory is based on his belief that everyone experienced eight developmental stages in their own life.
Piaget 's cognitive development theory: Piaget' s cognitive development theory thinks that children develop active knowledge when they operate and explore their world, and that development progresses step by step. This theory is divided into four stages: sensory movement, preoperative, specific surgery, and formal operation. Behavioral and Evolutionary Developmental Psychology: Behavioral attention to the adaptive value of behavior or survival value and its evolution history. That roots can be traced back to Darwin's work. The most famous of these is the early follow-up of the actions of several young birds, ensuring that young people are by their mothers and nourished and protected from danger. Imprinting leads to a critical period that refers to the period of time during which a child is biologically prepared to acquire adaptive behavior, but needs to stimulate environmental support.
Adolescence is also a period of change in the process of cognitive development. Piaget has developed a cognitive development theory emphasizing the four stages that children have to experience. The four stages of Piaget's cognitive development stage are as follows. Sensory movement, preoperative, specific surgical and formal surgical stages. Since the focus of this article is adolescence, we will describe in detail the formal operation stage of 11 years old and older. Features of the formal operation stage are abstract thinking, logical thinking, and hypothetical reasoning. During Piaget's official activities, children have acquired abstract and hypothetical thought skills. In other words, the children can ask themselves about the hypothesis of the "hypothesis" type. And it further demonstrates their ability to create and test concepts.
