Feschner: the (cid:373)ag(cid:374)itude of o(cid:374)e(cid:859)s se(cid:374)sor(cid:455) e(cid:454)perie(cid:374)(cid:272)e is the su(cid:373) of the j(cid:374)ds from absolute threshold to the differential threshold associated with the baseline stimulus intensity of the present comparison level. Says the relationship between the physical stimulus intensity ( and the experienced perceptual magnitutde is described by a power law. Equal physical stimulus rations produce equal perceived response magnitudes: a human and a cat stand facing an oncoming car at night. The driver of the car only sees one pair of eyes in her headlights. The dri(cid:448)er o(cid:374)l(cid:455) sees the (cid:272)at(cid:859)s pair of e(cid:455)es.
