For ϴLaser values less than 80° or greater than 120°, the subjects had near-perfect performance, but this table summarizes the pattern of errors for the worst ϴLaser values. The diagonal cells in each matrix (in italics) are the percent correct responses whereas the off-diagonal cells show the pattern of confusions.
