Two experiments examined the effects of phonotactic probability and neighborhood density on word learning by 3-, 4-, and 5-year-old children. Nonwords orthogonally varying in probability and density were taught with learning and retention measured via picture naming. Experiment 1 used a within story probability/across story density exposure…

Despite arguments for the relative ease of learning common noun meanings, semantic development continues well past the early years of language acquisition even for names of concrete objects. We studied evolution of the use of common nouns during later lexical development. Children aged 5-14 years and adults named common household objects and their…

Several recent experiments indicate that, when learning words, children are not as sensitive to phonemic differences (e.g., /d/ vs. /t/) as they are in discrimination tasks [Pater, J., Stager, C. L., & Werker, J. F. (2004). "The perceptual acquisition of phonological contrasts." "Language," 80, 384-402; Stager, C. L., & Werker, J. F. (1997).…
