用两种不同的方法测量了18个观测者的34个亮度函数。在一种方法中，观察者设置白色目标的各种亮度水平，并分配与所设置的水平的表观亮度成比例的数字。在另一种方法中，观察者调节白色噪声的响度和白色目标的亮度，以实现响度和亮度之间的一系列跨模态匹配。这两种方法都给出了很好的近似幂函数，表明心理物理幂律适用于个人感知者。
A total of 34 individual brightness functions were measured for 18 observers by two different methods. In one method the observer set various luminance levels of a white target and assigned numbers proportional to the apparent brightness of the levels set. In the other method the observer adjusted the loudness of a white noise and the luminance of a white target in order to achieve a series of cross-modality matches between loudness and brightness. Both methods gave good approximations to power functions, showing that the psychophysical power law holds for the individual perceiver.
