Egocentric Spatial Representation in Action and Perception*
Neuropsychological findings used to motivate the ‘‘two visual systems’’ hypothesis have been taken to endanger a pair of widely accepted claims about spatial representation in conscious visual experience. The first is the claim that visual experience represents 3-D space around the perceiver using an egocentric frame of reference. The second is the claim that there is a constitutive link betwee...
متن کاملEgocentric spatial representation in early
Neurons encoding simple visual features in area V1 such as orientation, direction of motion and color are organized in retinotopic maps. However, recent physiological experiments have shown that the responses of many neurons in V1 and V3a are modulated by the direction of gaze. We have developed a neural network model of the hierarchy of maps in visual cortex to explore the hypothesis that visu...
متن کاملEgocentric Spatial Representation in Early Vision
Recent physiological experiments have shown that the responses of many neurons in V1 and V3a are modulated by the direction of gaze. We have developed a neural network model of the hierarchy of maps in visual cortex to explore the hypothesis that visual features are encoded in egocentric (spatiotopic) coordinates at early stages of visual processing. Most psychophysical studies that have attemp...
متن کاملAsymmetric Influence of Egocentric Representation onto Allocentric Perception.
Objects in the visual world can be represented in both egocentric and allocentric coordinates. Previous studies have found that allocentric representation can affect the accuracy of spatial judgment relative to an egocentric frame, but not vice versa. Here we asked whether egocentric representation influenced the processing speed of allocentric perception. We measured the manual reaction time o...
متن کاملEgocentric qualitative spatial knowledge representation for physical robots
Although recent (physical) robots have powerful sensors and actuators their abilities to show intelligent behavior is often limited. One key reason is the lack of an appropriate spatial representation. Spatial knowledge plays a crucial role in navigation, (selfand object-)localization, planning and reasoning for physical grounded robots. However, it is a major difficulty of most existing approa...
