Prediction error plays a pivotal role in theories of learning, including theories of language acquisition and use. Researchers have investigated whether and under which conditions children, like adults, use prediction to facilitate language comprehension at different levels of linguistic representation. However, many aspects of the reciprocal…

Children's understanding of passives of certain mental state predicates appears to lag behind passives of so-called actional predicates, an asymmetry that has posed a major empirical challenge for theories of passive acquisition. This paper argues against the dominant view in the literature that treats the predicate-based asymmetry as…

Humans can attribute beliefs to others. However, it is unknown to what extent this ability results from an innate biological endowment or from experience accrued through child development, particularly exposure to language describing others' mental states. We test the viability of the language exposure hypothesis by assessing whether models…

Poverty of the stimulus has been at the heart of ferocious and tear-filled debates at the nexus of psychology, linguistics, and philosophy for decades. This review is intended as a guide for readers without a formal linguistics or philosophy background, focusing on what poverty of the stimulus is and how it's been interpreted, which is…

Mikhail Bakhtin is a latecomer to the field of child development. His contributions emphasize the dialogic nature of language as a lived event of becoming for all and de-thrones any monologic truths that might be told otherwise. Dismantling any master theory that might determine the ways children are known (or know-able), Bakhtin offers a…

Linguistic alignment--the contingent reuse of our interlocutors' language at all levels of linguistic structure--pervades human dialogue. Here, we design unique measures to capture the degree of linguistic alignment between interlocutors' linguistic representations at three levels of structure: lexical, syntactic, and semantic. We track these…

Previous papers in these pages have dealt empirically with the child's first words, the child's first imitations, and the use of yes/no and wh-questions with infants. In this study, we touch on all these issues, but attempt to place them in a systemic-functional language framework and a cultural-historical learning one. First, we deal with some of…

This dissertation focuses on when and how children learn about the meanings of the propositional attitude" verbs know" and "think". "Know" and "think" both express belief. But they differ in their veridicality: "think" is non-veridical and can report a false belief; but "know" can only…

Acquisition in general and first language acquisition in particular is a very complex and a multifaceted phenomenon. The way that children acquire a language in a very limited period is astonishing. Various approaches have been proposed so far to account for this extraordinary phenomenon. These approaches are indeed based on various philosophical…

Infants' phonological acquisition during the first 18 months of life has been studied within experimental psychology for some 30 years. Current research themes include statistical learning mechanisms, early lexical development, and models of phonetic category perception. So far, linguistic theories have hardly been taken into account. These…

A fundamental problem in language acquisition is determining how children learn the formal vocabulary of the adult grammar. A proposed solution is the Semantic Bootstrapping Hypothesis (SBH), which states that children infer the identity of syntactic entities such as "subject" in input based on the presence of semantic entities such as…

An experiment on children aged 2 to 7 led to a critical evaluation of Piaget's implicit contention that young children use determiners anaphorically. It is suggested that the importance of young children's processing procedures on the linguistic environment has been underestimated in Piaget's interactive epistemology. (CHK)

Numerous findings suggest that non-native speech perception undergoes dramatic changes before the infant' s first birthday. Yet the nature and cause of these changes remain uncertain. We evaluated the predictions of several theoretical accounts of developmental change in infants' perception of non-native consonant contrasts. Experiment 1 assessed…
