Document Summary

Distinguishing differences in spacing of facial features develops more slowly than distinguishing between facial contours. Babies can discriminate between speech sounds as early as 1 month of age (cid:894)(cid:862)pa(cid:863) (cid:862)(cid:271)a(cid:863)(cid:895) By 6 (cid:373)o(cid:374)ths, (cid:271)a(cid:271)ies (cid:272)a(cid:374) disti(cid:374)guish (cid:271)et(cid:449)ee(cid:374) 2 sylla(cid:271)le (cid:449)ords (cid:894)(cid:862)(cid:271)ada(cid:863) (cid:862)(cid:271)aga(cid:863)(cid:895) Can also distinguish between word and non-words in artificial languages. Babies are better at discriminating some kinds of speech sounds than adults are. Up until 6 months of age, babies can discriminate all sound contrasts that appear in any language o. Including sounds they do not hear in the language spoken to them. At 6 (cid:373)o(cid:374)ths, lose a(cid:271)ility to disti(cid:374)guish pairs of (cid:448)o(cid:449)els that do(cid:374)"t o(cid:272)(cid:272)ur i(cid:374) the la(cid:374)guage they hear. Age 1, ability to discriminate non-heard consonant contrasts fades. Loss of ability is consistent with process of synaptic pruning. Newborns are capable of discriminating between individual voices.
