Document Summary
From low-level processing (sensory input) to retrieval of meaning (lexical access) Word recognition: word is recognized and the recognition point usually occurs before the complete word has been heard. Gating task work: a paradigm used to study spoken word. Lexical decision task, word spotting task, gating task. recognition. The point at which a word is recognized before its uniqueness point = isolation point of recognition. Words starting w/ /sha/ : shop, shock, shark, shot, shovel => as more segments become available, the final candidate is selected. Cohort model: access state -> selection state -> integration state (context) top down not necessary; emphasis on bottom up process (perceptual cues, features, transitional cues) The basics of the trace model - highly interaction model of spoken word recognition. Connectionist (many simple processing units connected together) and interactive model; lexical context can directly assist acoustic- perceptual processing and info above the word level can directly influence word processing.
