The connotation of convincing theory is to change the attitudes through accepting other people’s information.This paper used the control experiments method,through exposing the subjects to some GMF information,to observe and measure whether or not the attitude and behavior about GMF will change.200 freshmen were randomly selected to participate in the experiment.These students were divided into experimental group and control group,the experimental group was asked to read a set of PPT materials about GMF and the control group was used for comparative observation.Results showed that the tendency of information attitude will lead to the significant changes in attitudes and behaviors about GMF.Meanwhile,the impact of the identity of information providers is not obvious,and the relationship between the attitude change and behavior change is weakly related.
