Visual egocentric localization: An experimental study

Jan H. Bruell, Clark University


Egocentric localization was defined as localization of objects with respect to one's body. This study dealt with visual egocentric localization, specifically with the visual perception of the median plane.

In a historical introduction evidence was presented which showed that both retinal and muscular factors are detriments of visual egocentric localization. The need for a theory which would do away with the dichotomy of retinal vs. muscular factors was pointed out by referring to Werner and Wapner's views on these matters. A Theory which stressed the interaction of both factors was proposed. Implications of this theory were tested in three experiments.
