Processing of asymmetrical noise in two- and three-dimensional global symmetry.

ABSTRACT

Studied how the visual system processes asymmetrical noise in globally symmetrical patterns and how much noise the visual system needs to distinguish between perfectly symmetrical and imperfectly symmetrical patterns. Human Ss: Four normal Japanese adults (graduate students). Two experienced and 2 inexperienced Ss were asked to detect 2-dimensional and 3-dimensional mirror symmetry in random dot displays. The use of parallel processing vs serial processing was analyzed.
