Below are summaries of two studies exploring the dangers of texting while driving. Read each summary and then comment on which study, 1 or 2, you think provides stronger evidence that texting while driving is dangerous. Explain your reasoning by laying out the facts (identify the scientific studies being done, potential errors, etc.) from these two studies and implications that led you to your conclusion. Study 1: Drivers in this study were between the ages of 16 and 54, and they performed on a closed course, with no other cars or pedestrians present. The idea of “danger” was measured by drivers’ reaction time—the time from seeing a flashing yellow light until they applied the car breaks. The treatment condi- tions in this study were: sending text messages, reading text messages, and a control condition in which drivers completely focused on the road. Study 2: Drivers in this study were long-haul truck drivers, and their behavior was recorded using several cameras inside the cab of their truck. In this study, the idea of “danger” was measured by recording whether or not the driver crashed. The treatment variable was “texting,” but it is not clear if any distinction was made between sending or reading text messages, or between using a keyboard to type a message versus using voice to text software.
