 They then found that said standards affected the actual evaluation of the president's performance, demonstrating priming.This experiment points to the potential of news media to direct the public's attention and perception of political figures, though the researchers also indicate that subjects with higher self-reported levels of knowledge of politics showed decreased effects of priming.This lead Iyengar's team to the conclusion that priming has varied implications depending on an individual's given knowledge prior to political news media exposure.
