title: Persuasive images in popular science: Testing judgments of scientific reasoning and credibility.
abstract: This article tested the assumption that functional magnetic resonance imaging (fMRI) images in popular science news articles make those articles appear more reasonable and persuasive to readers. In addition to fMRI images, this study also examined the potential impact of science fiction and artistic images commonly found in popular news articles. 183 undergraduates were asked to evaluate one of four versions of an article, each with a different image. The researchers discovered no significant differences between readers' evaluations of the news article with the images isolated as the only independent variable. This suggests that images alone may not have a strong effect upon evaluation, that no image is necessarily more persuasive than another as implied by earlier studies and that further research is needed to determine what, if any, role images play in conjunction with the text to create a persuasive effect.
