Document Summary
Started studying human development scientifically about 100 years ago. Brother- henry james: what"s a (cid:271)a(cid:271)(cid:455)"s thoughts like? (cid:862)bloo(cid:373)i(cid:374)g, (cid:271)uzzi(cid:374)g (cid:272)o(cid:374)fusio(cid:374)(cid:863, empiricist in his outlook (what a person experiences). When infant born, they have no e(cid:454)pe(cid:396)ie(cid:374)(cid:272)es so the(cid:455) do(cid:374)"t k(cid:374)o(cid:449) a(cid:374)(cid:455)thi(cid:374)g. a(cid:374)(cid:455)thi(cid:374)g the(cid:455) see o(cid:396) hea(cid:396) is a (cid:374)e(cid:449) e(cid:454)pe(cid:396)ie(cid:374)(cid:272)e so it"s all (cid:272)o(cid:374)fusio(cid:374): when born, not capable of perception yet. Developmental psychology is a science- follo(cid:449)s the s(cid:272)ie(cid:374)tifi(cid:272) (cid:373)ethod. If you make a mistake you will eventually find out and be able to fix it. If a stimulus is constant, we learn to ignore it: high amplitude suckling method- relies on fact that pacifie(cid:396) i(cid:374) (cid:271)a(cid:271)(cid:455)"s (cid:373)outh, the(cid:455) sta(cid:396)t suckling. Motion sensor hooked up to graphic display of paper. Infant sucked on pacifier, put a tick on the graph. Suckling slows down or stops after hearing first sound. If the sou(cid:374)d is (cid:272)o(cid:374)sta(cid:374)t, the(cid:455)"ll ha(cid:271)ituate to it a(cid:374)d sta(cid:396)t su(cid:272)kli(cid:374)g agai(cid:374). At so(cid:373)e poi(cid:374)t afte(cid:396) habituation, do sound two.
