The present study investigates the effects of on-screen messages on viewer perceptions of source credibility and issue valence. Previous research has found that elites utilize framing in order to alter viewer perceptions and change public opinion. An experiment was conducted, which examined whether on-screen messages displayed during a presidential-news conference had any effect on the viewers' perception of sound credibility and issue valence. The results of the study indicate that on-screen messages have no effect on individuals' perceptions of source credibility and issue valence. The study also found that an individual's· political ideology plays a major role in influencing perceptions of source credibility and issue valence.
