The mapping of visual space is a function of the structure of the visual field

摘要: Flanders et al.'s model predicts that subjects use a shouldercentered reference system to determine the position of remembered targets for reaching. Other studies goal-directed arm movements have found other areas in bodv architecture be center coordinate (e.g.: head-centered: Bard al. 1990; Biguer 1982; trunk-centered: Yardley 1990). Common these is suggestion an egocentric (or bodycentered) used process spatial information. Discrepancies among models arise from identification system's origin. A body-centered mapping refers sensorimotor mode processing information characterized by direct dialogue with physical world continuously updating proprioceptive registration gaze direction (Paillard 1986). In addition bodycentered systems, there experimental evidence existence allocentric frame capable cognitively and thus determining object space (Bridgeman 1979; 1989; Paillard 1981; 1991). This derives memory-based internal construct built extracting stable covariant features structured visual environment. It corresponds representational 1986) or cognitive 1989)
