Purpose: Recent studies from the authors' laboratory have suggested that reduced audibility in the high frequencies (because of the bandwidth of hearing instruments) may play a role in the delays in phonological development often exhibited by children with hearing impairment. The goal of the current study was to extend previous findings on the…

Adults can learn new artificial phonotactic constraints by producing syllables that exhibit the constraints. The experiments presented here tested the limits of phonotactic learning in production using speech errors as an implicit measure of learning. Experiment 1 tested a constraint in which the placement of a consonant as an onset or coda…

Pavlenko's keynote paper calls for a rethinking of models of the mental lexicon in the light of recent research into emotion and bilingualism. The author makes a convincing case for the inclusion of affective aspects in the study of the mental lexicon. Indeed, the knowledge of the degree of emotionality of a word and of its affective valence is…

Although many researchers have examined the effects of anxiety on second language learning in recent years, the specific sources and effects of language anxiety have not yet been clearly established. Moreover, few studies have specifically examined anxiety from the learner's perspective. Although previous interview and diary studies have pointed…

Research with adults has shown that ambiguous spoken sentences are resolved efficiently, exploiting multiple cues--including referential context--to select the intended meaning. Paradoxically, children appear to be insensitive to referential cues when resolving ambiguous sentences, relying instead on statistical properties intrinsic to the…

In their first few years, almost all children learn at least one language, though not equally well. Differences in the quantity, quality, sources, and variety of language inputs and conversation opportunities have a long-lasting effect. This article provides an overview of early language development and explains how talking with babies promotes…

Are thematic roles linked to verbs in young children as in adults or will children accept any participant in a given role with any verb? To assess early verb comprehension we used typicality ratings with adults, parental questionnaires, and Intermodal Preferential Looking with children. We predicted that children would look at named targets, would…

Background: Grounded in sociocultural theories of language development and use, this paper explores the concept of dialogic voice. Building on the term "dialogue", dialogic voice points to the fundamentally social nature of language-in-use. From this perspective, language emerges from specific histories and thus carries the multiple voices of…

A wealth of human knowledge is acquired by attending to information provided by other people--but some people are more credible sources than others. In two experiments, we explored whether young children spontaneously keep track of an individual's history of being accurate or inaccurate and use this information to facilitate subsequent learning.…

This article addresses the acquisition of meaning of words and phrases that refer to aspects of the world that are not directly perceivable. It examines the patterns of semantic input that are available in the linguistic environment that provide clues to allow a child to construct a lexicon that is both broad and deep. These patterns are…

Past research has indicated that English-learning infants begin segmenting words from speech by 7.5 months of age (Jusczyk & Aslin, 1995). More recent work has demonstrated, however, that 7.5-month-olds' segmentation abilities are severely limited. For example, the ability to segment vowel-initial words from speech reportedly does not appear until…

Researchers have long noted that children's grammatical morphemes are variably produced, raising questions about when and how grammatical competence is acquired. This study examined the spontaneous production of determiners by two French-speaking children aged 1 ; 5-2 ; 5. It found that determiners were produced earlier with monosyllabic words,…

This study examined the effect of a quasi-experimental project on fifth grade English learners' achievement in state-mandated standards-based science and English reading assessment. A total of 166 treatment students and 80 comparison students from four randomized intermediate schools participated in the current project. The intervention consisted…

Purpose: The purpose of this study was to determine whether children exposed to 2 languages would benefit from the phonotactic probability cues of a single language in the same way as monolingual peers and to determine whether crosslinguistic influence would be present in a fast-mapping task. Method: Two groups of typically developing children…

Children from low-income families benefit remarkably from exposure to compensatory education that began with Head Start in 1965 and aimed to improve school readiness skills by design. While empirical evidence has supported more instructional time in elementary and secondary schools for low-income students, little is known that whether increasing…
