8. Opinion taking refers to children's ability to infer other people's internal psychological activities, that is, to understand other people's thoughts, wishes and emotions. The essential feature of view taking is that indivials are self-centered in their cognition, that is, they can look at problems from the perspective of others. Therefore, an indivial must first be able to discover the potential differences between his own views and those of others, and distinguish his own views from those of others. However, to distinguish one's own views from others is not to choose others' views. Only by making accurate inferences about others' views on the basis of differentiation can one really have the ability to choose views. The ability of opinion taking is developed under the stimulation of extensive social interaction and colorful social clues, which has an important impact on children's personality and social development
some contemporary developmental psychology theorists and researchers have developed Piaget's views on children's cognition and put forward various stage models to describe the development of children's view taking ability. There are mainly two theoretical models:
Flavell divides a series of cognitive psychological actions that occur when children adopt opinions into four stages according to the order of occurrence: 1. Cognitive evaluation of others has the possibility of different views (attitude, knowledge, etc.) from their own. Children realize that people have different views on a certain event or situation. 2. Need stage. Children realize that it is necessary to infer the opinions of others in order to achieve their goal of interpersonal communication, persuade others and win in the game. 3. Inference stage. The cognitive activities in this stage include all psychological activities except perception. The purpose of these activities is to infer the views of others in a particular situation, that is, character characteristics. 4. Application stage. Indivials apply their inferential information to subsequent behaviors, such as what to say and how to say to others
Salman used the dilemma story of "Holly climbing the tree" to study children's perspective taking ability. According to the children's reaction, Selman divides the development of view taking ability into five stages: stage 0: egocentric view taking. Children cannot distinguish between their own interpretation of events and what they believe to be true or correct. Stage 1: social information perspective selection (about 6-8 years old). Children are aware that others have different understandings and opinions. Stage 2: self reflective viewpoint selection (about 8-10 years old). Children realize that everyone knows that others have their own thoughts and feelings. They not only know that others have different views, but also can be aware of others' views. Stage 3: mutual viewpoint selection (10-12 years old). Children can view the interaction of two people from the perspective of a third party and a common friend. Stage 4: viewpoint selection of social and custom system (over 12-15 years old). Children recognize that there is a comprehensive view, and also recognize that "in order to accurately interact with others and understand others, each self should consider the common view of the social system."
