When children learn the name of a novel object, they tend to extend that name to other objects similar in shape--a phenomenon referred to as the shape bias. Does the shape bias stem from learned associations between names and categories of objects, or does it derive from more general properties of children's understanding of language and the…

Children's early word productions often differ from the target form, sometimes exhibiting vowel lengthening when word-final coda consonants are omitted (e.g., "dog" /d[open o]g/ [arrow right] [d[open o]:]). It has typically been assumed that such lengthening compensates for a missing prosodic unit (a mora). However, this study raises the…

The forms of words as they appear in text and speech are central to theories and models of lexical processing. Nonetheless, current methods for simulating their learning and representation fail to approach the scale and heterogeneity of real wordform lexicons. A connectionist architecture termed the "sequence encoder" is used to learn…

This paper examines the findings and implications of the cross-linguistic acquisition of #sC clusters in relation to sonority patterns. Data from individual studies on English, Dutch, Norwegian, and Hebrew are compared for accuracy of production as well as the reductions with respect to potential differences across subtypes of #sC groups. In all…

Rapid acquisition of linguistic categories or constructions is sometimes regarded as evidence of innate knowledge. In this paper, we examine Polish children's early understanding of an idiosyncratic, language-specific construction involving the instrumental case--which could not be due to innate knowledge. Thirty Polish-speaking children aged 2; 6…

Young children learning English are biased to attend to the shape of solid rigid objects when learning novel names. This study seeks further understanding of the processes that support this behavior by examining a previous finding that three-year-old children are also biased to generalize novel names for objects made from deformable materials by…

This study investigated trajectories of Korean children's growth in the awareness of four phonological units--"syllable," "body," "rime" and "phoneme"--over time, by following a sample of 215 children over a period of 15 months, beginning at their first year of preschool and collecting four waves of data. Much of the existing research suggests…

Each clause and phrase boundary necessarily aligns with a word boundary. Thus, infants' attention to the edges of clauses and phrases may help them learn some of the language-specific cues defining word boundaries. Attention to prosodically well-formed clauses and phrases may also help infants begin to extract information important for learning…

Variation set structure--partial overlap of successive utterances in child-directed speech--has been shown to correlate with progress in children's acquisition of syntax. We demonstrate the benefits of variation set structure directly: in miniature artificial languages, arranging a certain proportion of utterances in a training corpus in variation…

The "weaker links" hypothesis proposes that bilinguals are disadvantaged relative to monolinguals on speaking tasks because they divide frequency-of-use between two languages. To test this proposal, we contrasted the effects of increased word use associated with monolingualism, language dominance, and increased age on picture naming times. In two…

Repetition is a central phenomenon of behavior, and researchers have made extensive use of it to illuminate psychological functioning. In the language sciences, a ubiquitous form of such repetition is "structural priming," a tendency to repeat or better process a current sentence because of its structural similarity to a previously experienced…

LChildren pass through a stage in development when they produce utterances that contain auxiliary BE ("he's playing") and utterances where auxiliary BE is omitted ("he playing"). One explanation that has been put forward to explain this phenomenon is the presence of questions in the input that model S-V word order (Theakston, Lieven & Tomasello,…

The present study investigated the roles of pattern detection capacities and understanding of intentions in children's learning of linguistic rules. We taught two-year-olds a Hebrew morphological distinction between noun and verb forms using two different training protocols. The protocols were identical in all parameters except that only in an…

Strategies that produce generalized responding are valuable, especially with regard to language acquisition, because relatively little training may result in large behavior changes. Conditions that result in generalized manding were analyzed in the current study. We demonstrated in reversal designs that undesirable or single-word responses were…

The aim of the study was to examine whether auditory binaural interaction, defined as any difference between binaurally evoked responses and the sum of monaurally evoked responses, which is thought to index functions involved in the localization and detection of signals in background noise, is atypical in a group of children with specific language…
