WebThe relationship between stimulus intensity and sensation is described in Stevens' force law : S = aI b, in which the sensation ( S ) is related to stimulus intensity ( I ) by exponent b . If the exponent is less than 1, the sensation grows less rapidly than the stimulus. That is also what Fechners and Weber's laws predict. chrome pdf 转图片
