Identify the independent variable and its levels and the dependent variable and how it is being operationalized/measured. 5. An air force psychologist hypothesizes that environmental temperature will affect pilot’s reaction time. The task is to press, as quickly as possible, one of 5 buttons depending on which of 5 lights come on. Using 21 pilots, he tested each for 90 minutes. He assigned 7 pilots to a 70 degree room, another 7 pilots to a 90 degree room, and the last 7 pilots to a 40 degree room. On average the pilots in the 70 degree room took longer to respond than did the pilots in the 40 degree and 90 degree rooms. From these results, the air force psychologist concludes that the more uncomfortable the temperature (90 degrees and 40 degrees) the faster the reaction time (in seconds).
