The Psychological Experiment And Simulation Study On Individual Information Processing Under Social Influence

The individual information cognitive process is usually done in a particular social context, affected by social factors. Nowadays, for the continuous change in information dissemination channel characteristics and influence models of social interaction, the study of individual cognitive information process mechanism under social influence become the frontier and hot issues in developing.This thesis first provides an overview of the individual cognitive information process, distortion and bias of individual information cognitive process, summarize to the framework of cognitive system and cognitive biases, richly reveals the connotation of individual information cognitive process.Then, this thesis mainly summarizes the social learning theory, social cognitive theory, social comparison theory, cognitive dissonance theory, etc., and multiple social influence effects, such as conformity, polarization, minority/majority effects, social facilitation/inhibition, and so on, systematically investigating the social influence effects during information cognitive process.For the full range of inspection on the above influence mechanism is not realistic operability. This thesis presents the design and organization of psychological experiment, through the experimental manipulation, observing the social distortion and bias. In the psychological experiments, we discuss and verify the Internet group communication’s affect on individual attitudes (how individuals weigh the information they achieved from self and obtained from others).Finally, based on the individual information cognitive process mechanism under social influence, refines the core proposition, defines the decision variables and transfer function, constructs simulation system for use. We observe individual’s attitudes and preferences through social interaction and evolution, especially studying and verifying formation mechanism of the social influence factors to individual information cognitive process...
