Description |
In addition to the visual attention and working memory impairments described above, the lesions in Balints syndrome produce various defects in perception of visual object structure, motion, and depth. Information on object structure and depth is so important for interacting with objects and obstacles that our brains employ multiple cues. These cues include accommodation, convergence, binocular disparity, motion parallax, texture accretion/deletion, convergence of parallels, position relative to horizon, relative size, familiar size, texture gradients, edge interpretation, shading and shadows, and aerial perspective. Understanding the relationships among these redundant cues is an active research topic. |
