We possess many beliefs which have different mechanisms in their formation and change. The first purpose of the present article is to discuss how to approach the dynamics of belief change. And the concepts reality dependency and value dependency are proposed as factors of belief change. The second purpose is to report the results of an experiment on the effect of reality of informationin formation and change of belief as "knowlede". The reality is defined the degree of the vividness of information like being objective exsistence.<BR>101 experimental subjects are randomly assigned 2×2 conditions, which are initial information with low reality and incongruent information with low reality condition, intial low reality-incongruent high reality condition, initial high-incongruent low reality and initial high-incongruent high condition. The experimental task is to resolve a cognitive incongruent situation brought about providing an incongruent information after forming a belief by accepting provided information.<BR>The results showed that the reality of information has significant effects on belief formation and change. In addition, these suggest that the reality of information in belief formation and that of belief change have different effects.
