Ss 对在受控手指力的主动触摸条件下凹槽金属板的感知粗糙度进行了大小估计。板中的凹槽越宽，凹槽之间的平台越窄，或者手指力越大，感知到的粗糙度就越大。手指力的增加也略微增加了幅度估计函数的斜率，这表明不仅均匀表面的粗糙度，而且图案化表面的不同部分的粗糙度的对比也会因感觉表面的方式的变化而改变。在视觉中也有类似的效果，即照明的增加会增加表面的表观对比度。
Ss made magnitude estimates of the perceived roughness of grooved metal plates under conditions of active touch with controlled finger force. The wider the grooves in the plate, the narrower the lands between the grooves, or the greater the finger force, the greater was the perceived roughness. Increase in finger force also slightly increased the slope of the magnitude estimation function, suggesting not only that the roughness of a uniform surface but also the contrasts in the roughness of differing parts of a patterned surface would be altered by changes in the manner of feeling the surface. An analogous effect has been reported in vision, in that increases in illumination increase the apparent contrast of a surface.
