Perceiving Animacy From Deformation and Translation
In a cartoon, we often receive an animacy impression from a dynamic nonanimate object, such as a sponge or a flour sack, which does not have an animal-like shape. We hypothesize that the animacy impression of a nonanimal object could stem from dynamic patterns that are possibly fundamental for biological motion perception. Here we show that observers recognize the animacy of human jump actions ...
متن کاملPerceiving shape from shading.
Our visual experience of the world is based on two-dimensional images: nat patterns of varying light intensity and color faIling on a single plane of cells in the retina. Yet we come to perceive solidity and depth. We can do this because a number of cues about depth are available in the retinal image: shading, perspective, occlusion of one object by another and stereoscopic disparity. In some m...
متن کاملPerceiving Structure From Motion: Failure Of Shape Constancy
Four experiments are reported on human perception of structure from motion that show systematic failures of shape constancy as a function of object motion. Two of these experiments show that the perceived depth of an object undergoing sinusoidal oscillation about a vertical axis increases monotonically with the amplitude of oscillation. The other two experiments show how the shape of an object ...
متن کاملCortical regions involved in perceiving object shape.
The studies described here use functional magnetic resonance imaging to test whether common or distinct cognitive and/or neural mechanisms are involved in extracting object structure from the different image cues defining an object's shape, such as contours, shading, and monocular depth cues. We found overlapping activations in the lateral and ventral occipital cortex [known as the lateral occi...
متن کاملThe role of surface attraction in perceiving volumetric shape.
Rock [1973, Orientation and Form (New York: Academic Press)] showed that form perception generally depends more on the orientation of a stimulus in world coordinates than on its orientation in retinal coordinates. He suggested that the assignment of an object's 'environmental orientation' depends on gravity, visual frame of reference, and the observer's ability to impose orientation along one a...
