简介
Hills are judged to be steeper with a verbal measure (in degrees) than with a motor measure. Traditionally, studies of slope estimation have used relatively long distances (Proffitt, Creem, & Zosh, 2001). More recently, previous studies found verbal estimates greatly overestimated slopes (Effect of Distance & Surface Experiment) and these overestimates fit a log function as a function of increased distance (Fine-grained Distance Experiment). Based on these initial findings with regard to the role of distance in slope estimation, the current study was interested in further examining the relation of slope perceptual sensitivity across predetermined distances. The study replicated the effects of distance and type of measure on predetermined logarithmic distances but did not reproduce the interaction effect. Consistent with previous work, motor estimates were more accurate at all ranges. These results can be interpreted as modulation of the individual’s implicit slope by depth cues available at near distances that are not available at further distances. We conclude that geometric layout of the world interacts with effort required for interacting with the world?(Proffitt, Bhalla, Gossweiler, & Midgett, 1995), but more strongly for verbal than for motor measures.
