Note: σx, σy = perceptual standard deviations on dimensions x and y; Dx, Dy = decision boundary locations on dimensions x and y; +A, −B = random walk criteria; k = random-walk scaling constant; μR, σR = residual-time mean and standard deviation; μAS, σAS = attention-switch-time mean and standard deviation; px = probability that dimension x is processed before dimension y.
