2. Wendy participates in a color perception experiment in which she is presented with a constant green dot on the left side of the screen (wavelength = 530nm) and another dot on the right side of the screen that varies in wavelength across trials (500nm, 510nm, 520nm, 530nm, 540nm, 550nm, 560nm, or 570nm).
