Hierarchical structures play a central role in many aspects of human cognition, prominently including both language and music. In this study we addressed hierarchy in the visual domain, using a novel paradigm based on fractal images. Fractals are self-similar patterns generated by repeating the same simple rule at multiple hierarchical levels. Our(More)
Quantitative predictions of egocentric distance and geographical slant perception may be derived from dense coding (scale expansion) in angular variables (Durgin & Li, 2011). In particular, distance/height matching tasks can be accounted for by measured biases in perceived direction (elevation) relative to the horizon (Li et al., 2011). However, substantial(More)
Several individual differences including age have been suggested to affect the perception of slant. A cross-sectional study of outdoor hill estimation (N = 106) was analyzed using individual difference measures of age, experiential knowledge, fitness, personality traits, and sex. Of particular note, it was found that for participants who reported any(More)
Estimates of (geographical) hill slant are often higher for women than men. We collected estimates of slant for several hills from a cross-section of people from the nearby community and from college students. Prior research has suggested that knowledge about hill slant (e.g., from experience with skiing) has a corrective impact on hill slant estimation but(More)
which can surmount indoor stairs or steps by virtue of a new contact angle estimation method. First, link parameters of the rocker-bogie mechanism are optimized through the Taguchi method, with the aim of making the trajectory of the center of mass (CM) of the mobile platform as smooth as possible. Based on the optimization result, the mobile platform is(More)
