Bike Helmet Ted Talks-Visual Evidence

The use of visual evidence in the two talks differed strongly in their effects. The pro-helmet speaker relied heavily on text and bullet points, with a similar format running throughout all the slides. This yielded little added strength to his argument, overstimulating the language part of the brain rather than making his point clearer. The wide variety of ads, images, text, statistics, and quotes employed by the second speaker added a lot to his presentation, illustrating his points in different, easy-to-understand ways. There was also an added level of creativity in the car-safety ads that he made, which combined the statistical similarities between the effects of cars and cigarettes, another parallel that strengthened his argument.
