Age-of-Acquisition, Word Frequency, and Neighborhood Density Effects on Spoken Word Recognition by Children and Adults☆

摘要: This study assessed how lexical factors associated with vocabulary growth influence spoken word recognition by preschoolers, elementary-school children, and adults. Word frequency effects in gating repetition tasks were minimal, whereas age-of-acquisition neighborhood density found for all listeners. For repetition, children displayed more of an advantage the early-acquired items from sparse vs dense neighborhoods than did adults; adults showed a greater later-acquired items. Regression analyses revealed that contributed to phonological awareness among individual children. In turn, awareness, receptive vocabulary, verbal short-term memory reading. These findings are discussed terms recent proposals about level processing at which exerts either facilitatory or inhibitory effects. The development early reading skill is also discussed.
