People may perceive sound differently, depending on how in shape they are. Researchers have previously shown that women respond to oncoming noise sooner than men, supporting the view that stronger people require less time to react to impending danger. In the latest study from Ohio, scientists say that response time is not based on someone’s gender, height, or weight, but instead, relies on how fit a person is.
“This is the first evidence that our motor system and the perception of looming sounds evolved together,” John Neuhoff, an evolutionary psychologist at the College of Wooster and lead researcher on the study, told DISCOVER. Neuhoff tested 50 people, ranging from college students to 43-year-old couch potatoes, for strength and cardiovascular fitness. He categorized his subjects based on their fitness level, measuring their pulse rate for 60 seconds after they marched for three minutes.
