Document Summary
Core problem of word recognition how do we resolve the potential ambiguity between words that arises when close distinctions must be made when listening to speech (and while reading) Basic computational models of spoken and visual word recognition that implement particular mechanisms for helping resolve ambiguity in input. Visuo-spatial (sign languages: these linguistic modalities are for perceptual word forms (arbitrary signs) that map onto concepts (semantics) Lexical access the process whereby the memory for a specific word form is located, (cid:862)ope(cid:374)ed(cid:863) or (cid:862)a(cid:272)ti(cid:448)ated(cid:863: words are perceptual objects. We can attend to the physical forms of words to help guide our thought processes. We (cid:272)a(cid:374) (cid:373)a(cid:374)ipulate for(cid:373)s of (cid:449)ords as ph(cid:455)si(cid:272)al o(cid:271)je(cid:272)ts as a (cid:373)ea(cid:374)s of (cid:862)tur(cid:374)i(cid:374)g ideas arou(cid:374)d(cid:863) i(cid:374) our (cid:373)i(cid:374)ds. Listeners cannot count on pauses between words for word recognition, hence they must rely on other information in the speech signal to indicate how word boundaries are marked: word boundaries.
