{"pk":49920,"title":"Looking beyond parental reports: systematic biases in early word recognition assessment","subtitle":null,"abstract":"This study examines convergence between parental reports and behavioral measures in assessing early word knowledge of twenty-eight 14-month-old Korean infants. We compared infants' word recognition patterns with parental reports using full and shorter versions of the Korean MacArthur-Bates Communicative Development Inventories (MCDI-K). Our analyses revealed three key patterns. First, while parents showed consistent judgment between the full CDI and the target-word checklist, the checklist demonstrated better convergence with eye-tracking measures, which accounted for baseline looking biases. Second, parents' reporting accuracy varied systematically with item difficulty: for early-acquired words, parents showed higher agreement with eye-tracking than for later-acquired words. Third, exploratory analyses suggested a possible asymmetry in word category recognition, with infants showing stronger recognition of nouns than verbs in the eye-tracking task, contrasting with more balanced verb-noun knowledge in parental reports. These findings show that assessment methods capture different aspects of early word knowledge.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Psychology; Cognitive development; Language acquisition; Language Comprehension; Eye tracking; Quantitative Behavior"}],"section":"Papers with Poster Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/7511s972","frozenauthors":[{"first_name":"Jun Ho","middle_name":"","last_name":"Chai","name_suffix":"","institution":"Sunway University","department":""},{"first_name":"Margarethe","middle_name":"","last_name":"McDonald","name_suffix":"","institution":"University of Kansas","department":""},{"first_name":"Eon-Suk","middle_name":"","last_name":"Ko","name_suffix":"","institution":"Chosun University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2025-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/49920/galley/37882/download/"}]}
