Age of acquisition (AoA) refers to the age at which people learn a particular item and the AoA effect refers to the phenomenon that early-acquired items are processed more quickly and accurately than those acquired later. Over several decades, the AoA effect has been investigated using neuroscientific, behavioral, corpus and computational…

Research on recognition of complex words has primarily focused on affixational complexity in concatenative languages. This dissertation investigates both templatic and affixational complexity in Hebrew, a templatic language, with particular focus on the role of the root and template morphemes in recognition. It also explores the role of morphology…

We examined how age of acquisition in Spanish heritage speakers and L2 learners interacts with implicitness vs. explicitness of tasks in gender processing of canonical and non-canonical ending nouns. Twenty-three Spanish native speakers, 29 heritage speakers, and 33 proficiency-matched L2 learners completed three on-line spoken word recognition…

Word age-of-acquisition (AoA) affects reading. The mapping hypothesis predicts AoA effects when input--output mappings are arbitrary. In Spanish, the orthography-to-phonology mappings required for word naming are consistent; therefore, no AoA effects are expected. Nevertheless, AoA effects have been found, motivating the present investigation of…

When addressing infants, many adults adopt a particular type of speech, known as infant-directed speech (IDS). IDS is characterized by exaggerated intonation, as well as reduced speech rate, shorter utterance duration, and grammatical simplification. It is commonly asserted that IDS serves in part to facilitate language learning. Although…

The present study investigated the mechanisms underlying perceptual compensation for assimilation in novel words. During training, participants learned canonical versions of novel spoken words (e.g., "decibot") presented in isolation. Following exposure to a second set of novel words the next day, participants carried out a phoneme…

Research has shown that the comprehension of definite referring expressions (e.g., "the triangle") tends to be faster for "given" (previously mentioned) referents, compared with new referents. This has been attributed to the presence of given information in the consciousness of discourse participants (e.g., Chafe, 1994) suggesting that given is…

In two experiments, 1.5-year-olds were taught novel words whose sound patterns were phonologically similar to familiar words (novel neighbors) or were not (novel nonneighbors). Learning was tested using a picture-fixation task. In both experiments, children learned the novel nonneighbors but not the novel neighbors. In addition, exposure to the…

Reports on a study in which subjects heard the beginnings of spoken words, followed by increasingly larger segments of word-onset information until the words could be correctly identified. Results are discussed in terms of word-initial phonology as a trigger for response activation. (34 references) (Author/OD)

Assessment of two-year-olds' (N=22) acquisition of words for referents of previously learned words indicated that young children found it easier to learn a new word when they were able to contrast its referent with that of a word they already knew. (Author/CB)

Three experiments investigated the processes by which 2-year-olds acquire the language to express category hierarchies. The first experiment studied how children use current linguistic knowledge to constrain the potential meanings of new words. This experiment compared interpretations of new words given to objects the children could already name…

Explains distributional regularity (DR), an intuition that sound sequences occurring frequently and in multiple contexts are candidates for the lexicon. Describes study that proposed hypotheses about children's segmenting sounds using DR functions, exploiting phonotactic constraints on pronunciation, and learning word-boundary clusters. Details…

The developmental nature of the reflective concept of "word" in young children was investigated and the degree to which these developmental aspects of metalinguistic awareness correspond to levels of cognitive development as described by Piaget was studied. (HOD)

The recognition of multimorphemic French words was investigated using a procedure that allowed the position of first fixation of the eye to be manipulated and gaze durations to be recorded. (37 references) (Author/LB)

To study whether metalinguistic benefits of childhood bilingualism flow on to reading acquisition, word awareness skills were developed in one group of monolingual English children and in another "marginal bilingual" group. Results strengthen the argument for a causal role in reading acquisition for word awareness. (Contains 63…
