There is a surprising degree of overlapping structure evident across the languages of the world. One factor leading to cross-linguistic similarities may be constraints on human learning abilities. Linguistic structures that are easier for infants to learn should predominate in human languages. If correct, then (a) human infants should more readily…

In previous research, Saffran and colleagues [Saffran, J. R., Aslin, R. N., & Newport, E. L. (1996). Statistical learning by 8-month-old infants. Science, 274, 1926-1928; Saffran, J. R., Newport, E. L., & Aslin, R. N. (1996). Word segmentation: The role of distributional cues. "Journal of Memory and Language," 35, 606-621.] have shown that adults…

Is past tense production better modelled by a Single Mechanism or a Words and Rules model? We present data concerning a phenomenon that has not been considered by either model--regular past tense verbs with contrasting phonotactics. One set of verbs contains clusters at the inflected verb end that also occur in monomorphemic words…

Investigated whether learning the distinction between substance names and object names is conceptually or linguistically driven, by repeating Soja et al.'s study with English- and Japanese-speaking children. (Japanese does not make the count-mass grammatical distinction proposed to contribute to learning the distinction.) Found evidence for…

Compares the many-perspectives account of lexical acquisition--which proposes that children learn to take alternative perspectives along with the words they acquire--to the one-perspective account--which proposes that children are at first able to use only one term to talk about an object or event. Provides evidence from a variety of sources that…

This study compared perception and production of Korean speech sounds by college students who had spoken Korean regularly for a few years during childhood to those of novice Korean learners and childhood hearers who had heard Korean regularly during childhood but had spoken Korean only minimally. Findings revealed long-term benefits of childhood…

Assessed semantic priming for category coordinates and function-related words in children with good or poor reading comprehension, matched for decoding skill. Found that both groups showed priming for function-related words, but poor comprehenders showed priming for category coordinates only if the pairs shared high-association strength. Good…

Two experiments investigated how child and adult speakers of English and Kannada (Dravidian) interpret scopally ambiguous sentences containing numerally quantified noun phrases and negation. Results showed that 4-year-olds' interpretations were constrained by the surface hierarchical relations (the c-command relations) between sentence elements…

The ''ba, ba, ba'' sound universal to babies' babbling around 7 months captures scientific attention because it provides insights into the mechanisms underlying language acquisition and vestiges of its evolutionary origins. Yet the prevailing mystery is what is the biological basis of babbling, with one hypothesis being that it is a non-linguistic…

Three studies investigated the comprehension of sentences containing the focus particle "only" by children and adults. Contrary to previous findings, two of the studies found that young children made errors predominantly by failing to process contrast information rather than errors in which they failed to use syntactic information to…

Compared gestures of Chinese and American deaf children who had not been exposed to a usable conventional language model with speech of hearing children learning Mandarin or English. Found that deaf children conveyed central elements of motion events in their communications. Deaf American and Chinese children used gestures to express motion in…
