The aim of this research is to determine the effect of source credibility in the advertisements on purchase intention by the cognitive response level. The research has been carried out by comparison of the two different commercials prepared for a water brand. Whereas the first ad film has a celebrity, expert and attractive source, there is no obvious feature of source at the second commercial. By using experimental design, the research was applied to two different groups with similar properties and two commercial films were shown to them. The initial attitudes of both groups were measured before the ads. Their cognitive responses and purchase intentions to the ads were measured after respondents watched the ads. The data obtained as a result of the experiment 2 (favorable-unfavorable) X 3 (positive-neutral-negative) was analyzed by factorial design. In this research we used a student sample (n = 159).In addition to the dependent variable, the two independent variables that contains purchase intention, respondents' initial attitude and cognitive response to the advertised product were added. Highly credible sources will be more persuasive than less credible sources when the receiver is initially unfavorable toward message. In addition, other findings and implications are given
