Perceiving geographical slant.
People judged the inclination of hills viewed either out-of-doors or in a computer-simulated virtual environment. Angle judgments were obtained by having people (1) provide verbal estimates, (2) adjust a representation of the hill's cross-section, and (3) adjust a tilt board with their unseen hand. Geographical slant was greatly overestimated according to the first two measures, but not the thi...
متن کاملPerceiving virtual geographical slant: action influences perception.
In 4 experiments, the authors varied the extent and nature of participant movement in a virtual environment to examine the influence of action on estimates of geographical slant. Previous studies showed that people consciously overestimate hill slant but can still accurately guide an action toward the hill (D. R. Proffitt, M. Bhalla, R. Gossweiler, & J. Midgett, 1995). Related studies suggest t...
متن کاملThe Role of Geographical Slant in VirtualEnvironment
for providing the VR{models used in this experiments. The authors thank Pavel Zahorik for comments and suggestions on an earlier draft of this manuscript. We are grateful to Scott Yu for providing the 3D model of our virtual environments lab shown in Fig. 1. Abstract. We have investigated the role of geographical slant in simple navigation and spatial memory tasks, using a computer graphics tow...
متن کاملAffordances matter in geographical slant perception.
We argue that the experimental conditions in the Durgin et al. (2009) study were so different from those in Bhalla and Proffitt (1999) that the results of the former study cannot be generalized to the latter. The participants in the Durgin et al. study viewed a 2-m-long ramp; those in Bhalla and Proffitt viewed expansive hills. When drawing generalizations from one study to another, equating ex...
متن کاملVisual-motor recalibration in geographical slant perception.
In 4 experiments, it was shown that hills appear steeper to people who are encumbered by wearing a heavy backpack (Experiment 1), are fatigued (Experiment 2), are of low physical fitness (Experiment 3), or are elderly and/or in declining health (Experiment 4). Visually guided actions are unaffected by these manipulations of physiological potential. Although dissociable, the awareness and action...
