Passage Three: Questions 46-50     People standing at the bottom or the top of a staircase tend to overestimate steepness of a slope and think the angle is 20 degrees more than it really is. And, people can exhaust themselves just by picturing the effort required to climb the slope. A new study suggests that our misperception of slope was not biased by fatigue or even fear of falling. Rather, we determine the steepness of a slope based both on our visual perception and our point of view—namely, people’s perception of how much motor effort the hills would require to climb. Researchers at Ohio State University asked 100 hundred passerby to estimate the angle of a set of stairs—which, of course, require no effort to ascend and another 100 to do the same for an escalator. To further explore if our visual perception would be influenced by height, the researchers asked half the subjects in each condition to estimate the angle of a set of stairs or an escalator from the bottom and the other half from the top. The researchers found that the participants assigned to the staircase group consistently overestimated the slant of a slope by approximately 20 degrees; hills looked steeper from the top than from the bottom, presumably they were more difficult and more dangerous to descend than to ascend. And, this perception was universally perceived both by younger and older participants assigned to the stairs group: college-age students and older people estimated slopes the same. This finding suggested that people’s perception of slant does not seem to relate to people’s age-related physiological condition.      However, misperception of slope steepness only happened at the chance level for the participants assigned to the escalator condition, in which case no motor effort was required to ascend to the top. The disparate findings obtained from the stairs and escalator groups collectively provided evidence suggesting that our perspective—perceiving how much motor effort would be involved in climbing a slopedoes affect our slant estimation process.
