The experimental study on censorship was conducted to investigate the effects of (1) censor power and (2) the type of freedom re-establishment of communication on the recipients' attitude change in hypothetical situations. The censor was either a powerful or powerless agent, and the type of freedom re-establishment was direct re-establishment of freedom, re-establishment of freedom by implication, or non-re-establishment of freedom. The results indicated that both of the two independent variables, i.e. (1) and (2), mentioned above did not influence the subjects' attitude change toward the censored communication topic. The subjects in the non-re-establishment condition perceived greater threat to freedom than those in the direct re-establishment condition. And the subjects in the direct re-establishment and re-establishment by implication conditions perceived the communicator more positively than those in the non-re-establishment condition. The results in the present experiment have been interpreted according to the psychological reactance theory.
