ILLUSTRATIVE ARTICLE: CONDUCTING EXPERIMENTS When a person feels safe, they counter-intuitively take more risks. This has been observed among people driving cars, kids on a playground, and bicy- clists. This is a problem: The point of safety equipment is not to encourage people to behave less safely! The safety equipment used in past research was designed to be used with the activity that participants completed for the study (e.g., bike helmet with riding a bike). Would the increased risk taking occur even if the equipment was not designed for the activity? Gamble and Walker (2016) attempted to address this question with an experimental manipulation and some clever deception by attempting to cred- ibly convince research subjects that they were taking part in an eye-tracking experiment that required either baseball cap or a helmet. They found that participants who wore the helmet showed higher levels of both risk taking and sensation seeking compared to those who wore the cap. First, acquire and read the article: Gamble, T., & Walker, I. (2016). Wearing a bicycle helmet can increase risk taking and sensation seeking in adults. Psychological Science, 27(2). 289-294. doi:10.1177/0956797615620784 Then, after reading the article, consider the following: 7. Evaluate the internal validity of this study. 8. Do you believe that their conclusion is justified, given the experiment and results
