Document Summary

The organization, identification, and interpretation of a sensation in order to form a mental representation. When sensors in the body convert physical signals from the environment into encoded neural signals sent to the central nervous system. Methods that measure the strength of a stimulus and the o(cid:271)se(cid:396)ve(cid:396)"s se(cid:374)sitivit(cid:455) to that stimulus. The minimal intensity needed to just barely detect a stimulus 50% of the time. The minimal change in a stimulus that can just barley be detected. The just noticeable difference of a stimulus is a constant proportion despite variations in intensity. The response to a stimulus depends both on a pe(cid:396)so(cid:374)"s se(cid:374)sitivit(cid:455) to the sti(cid:373)ulus i(cid:374) the p(cid:396)ese(cid:374)(cid:272)e of (cid:374)oise a(cid:374)d o(cid:374) a pe(cid:396)so(cid:374)"s decision criterion. Sensitivity to prolonged stimulation tends to decline over time as an organism adapt to current conditions. Light-sensitive tissue lining the back of the eyeball.
