  1. Time: Tuesday 10:40-12:10 Room: 8-309 Instructor: Mafuyu Kitahara Material: Balota D. A. (1994) “Visual word recognition” in M. A. Gernsbacher (ed.) Handbook of Psycholinguistics, pp. 303-358, San Diego: Academic Press. 2007-06-19pp.317-319

  2. Seidenberg & McClleland (1) • Good results • Regular words • Exception words • Nonwords • Freq x Regularity • Dual-route account • Hfreq reg >> fast lexical • Lfreq reg >> assembled • Hfreq ex >> fast lexical • Lfreq ex >> assembled+slow lexical+interference • Simulation shows the same results

  3. Seidenberg & McClleland (2) • Neighborhood • Target = “lint” • Friends = “mint”, “hint”, “tint” • Enemy = “pint [paint]” • Frequency of each matters mint hint lint E T pint tint T E

  4. Seidenberg & McClleland (3) • Problems • Dyslexia • Bias from nonwords/exception words • Subjects rely more on assembled • Attentional demands interfere assembled route • Meaning level • Error score simulation is poor in nonwords
