Abstract
Three expts. were concerned with shifts of the position of the apparent median plane, defined as the straight-ahead. A test figure extending asymmetrically to the left of fixation produces a shift of the apparent median plane relatively to the left, compared with a test figure extending asymmetrically to the right of fixation. The effect of asymmetrical figural extent was found to be significant irrespective of the degree of flux emanating from the figural surface. Furthermore, there was evidence for starting position effects, analogous to those previously found in studies on vertically; i.e., other things being equal, the position of the straight-ahead (apparent median plane) is relatively closest to the position in which a line is placed in the visual field; if a line is initially placed to the left of the objective median plane, in the objective median plane, or to the right of the objective median plane, the straight-ahead is shifted respectively more toward the left, more toward the center, more toward the right.Keywords
