Is a picture really worth 1,000 words? When it comes to fact-based news articles, how much do they add to the credibility of the articles? Researchers interested in the power of images to persuade readers have examined this issue in a number of studies. Imagine you read a brief article titled “Watching TV Is Related to Math Ability,” which claimed that watching television, because it activates the temporal lobe in the same way doing math problems does, can increase a person’s math ability. Imagine further that text was accompanied either by no image, a bar graph, or a brain image (Figure 2.3). Take a minute and complete the questions below and then turn the page to learn more.
