Linguistic analysis in word recognition Orthographies based on phonemes, syllables, morphemes. English units of transcription are phonemes phonemes combine to form morphemes Chinese units of transcription are characters correspond to syllables Chinese is not a syllabic system many character spellings for the samesyllable Symbols correspond to linguistic units: not treated monolithically
Chinese: A window on analytic processing. Character = syllable graphemic units smaller than the character (but not smaller than a syllable) exist even in logographic writing systems 80-95% characters are semantic-phonetic compounds phonetic semantic • Mapping syllable --> character (homophones) • Semantic components within Chinese characters • Phonological influences on semantic components
Homophony influences recognition Chinese: set of 1273 syllables (across tones, excl. gaps)transcribed by 7000+ characters in common usehomophone families in Chinese vary greatly.range is about 40 /shi4/ to 1 /si3/ English syllables: more variability in onsets and codas homophone families in English are limited. Homophony is greater in Chinese than English
English: phonemes O-P correspondence int --> /Int/ or /aInt/ Homophones: P-O correspondence 1:5 /it/ --> meet meet meat feet mete elite pete Chinese: syllables O-P correspondence 议 --> /yi4/ * Homophones: P-O correspondence 1:20 Relation of orthographic and phonological form *number indicates lexical tone.
Expt. 1: Does homophony influence recognition in Chinese? Homophonic mapping: syllable --> character Phonetic does not fully specify pronunciation. Control ‘frequency’ of syllable and visual complexity Collaborator: Shu Hua at Beijing Normal University Haiyan Zhou at Beijing Normal University
Chinese ‘spelling’ task Onset: Hear: /yi4/ See:意 • Judge: “yes” Hear: /yi4/ See:突 • Judge: “no” SS = Students at Beijing Normal University, China --------------------------------> time
Phonological- Orthographic syllable mapping influences performance in a ‘spelling’ task. Frequency ISI = onset Low frequency targets show P-O homophone effect large = many characters; small = few characters
Chinese characters are compositional but not productive34 % of words in Mainland Chinese texts consist of single character80-95% of characters are phonetic compounds
Semantic components serve a semantic cueing function. 桌 染 板 ‘desk’ ‘dye’ ‘plank’ 木means ‘wood’
Phonetic components 4000 phonetics for 1273 syllables phonetic can behave differently in different character contexts 26.3% of semantic-phonetic compounds are pronounced like their phonetic phonological information is • coded loosely at the level of the component • only in some characters • in phonological units greater than the phoneme • “typical” position is on right
Bivalent components serve a semantic or a phonetic function. 米means ‘rice’ and is pronounced mi3 糜 means “gruel” pronounced mi2
Expt. 2: Do readers treat characters analytically? Facilitation due to repetition of a semantic component in character recognition tasks. Reduce overall semantic similarity of prime and target manipulate semantic transparency attributes of a component defined over many characters Reduce overall form similarity of prime and target alter position of component Collaborators: Douglas Honorof at Haskins Laboratories Shu Hua at Beijing Normal University

Cross task comparison: Forward masked: attenuated semantics S+ = S- SOA 250: greater effect semantic similarity S+ ≠ S- Character decision: semantic emphasis Character naming: greater influence of phonology
Summary: Linguistic analysis in character recognition Exp. 1: Chinese character = syllable (≠ phonemes) Complexity O--> P mapping in a spelling task Exp. 2: Facilitation due to component repetition: ≠ simple relatedness among characters whole character relatedness is weak ≠ repetition of form change in component position ns Relation of component to character Decision Nam. semantic (P-T) at longer SOA S+ not S- neither S semantic (P-T) with mask both S neither S change function (P≠T) F- = C F- ≠ C
Conclusions for the non-Sinophone psycholinguist Naming slowed when the same component appeared as a phonetic, then as a semantic Interference reflects incompatible mappings: • Component —> phonology • Component —> semantics Processing of the semantic cannot arise at the level of the whole character: it must be analytic
