This study tests the hypothesis that developmental dyslexia is (partly) caused by a deficit in implicit sequential learning, by investigating whether infants at familial risk of dyslexia can track non-adjacent dependencies in an artificial language. An implicit learning deficit would hinder detection of such dependencies, which mark grammatical…

Children start producing ["necessary and sufficient"] conditionals relatively late. Past counterfactuals (PCFs), for example "If she had shut the cage, the rabbit wouldn't have escaped", are particularly problematic for children; despite evidence of comprehension in the preschool years, children aged eleven are still making…

Young infants' learning of words for abstract concepts like "all gone" and "eat," in contrast to their learning of more concrete words like "apple" and "shoe," may follow a relatively protracted developmental course. We examined whether infants know such abstract words. Parents named one of two events shown in side-by-side videos while their…

By 14 months, infants have become exquisite observers of others' behavior and successful word learners. But do they coordinate their early observational and language capacities to gain insight into the intentions of others? Building upon Gergely, Bekkering, and Kiraly's (2002) classic head-touch phenomenon, we consider the contribution of language…

We delineated the achievement of early speech-language milestones in 15 young children with Rett syndrome ("MECP2" positive) in the first two years of life using retrospective video analysis. By contrast to the commonly accepted concept that these children are normal in the pre-regression period, we found markedly atypical development of…

John McDowell begins his essay "Knowledge by Hearsay" (1993) by describing two ways language matters to epistemology. The first is that, by understanding and accepting someone else's utterance, a person can acquire knowledge. This is what philosophers call "knowledge by testimony." The second is that children acquire knowledge in the course of…

Before the end of the first year of life, infants begin to lose the ability to perceive distinctions between sounds that are not phonemic in their native language. It is typically assumed that this developmental change reflects the construction of language-specific phoneme categories, but how these categories are learned largely remains a mystery.…

Number words are generally used to refer to the exact cardinal value of a set, but cognitive scientists disagree about their meanings. Although most psychological analyses presuppose that numbers have exact semantics ("two" means exactly two), many linguistic accounts propose that numbers have lower-bounded semantics (at least two), and…

Understanding how people learn the phonological patterns of their language is a major challenge facing the field of phonology. In this dissertation, I approach the issue of phonological learning by focusing on "saltatory" alternations, which occur when two alternating sounds "leap over" an intermediate, invariant sound (e.g.,…

Research on joint attention and language learning has focused primarily on cues requiring visual access. However, this narrow focus cannot account for the emergence of language among some congenitally blind children who develop language on the same developmental timescale as their sighted peers. Findings from this longitudinal, retrospective study…

This study investigated the effects of explicit, rich vocabulary instruction on the word acquisition and reading comprehension of high school students. The quasi-experimental study employed a two-group pretest-posttest design, using students from two intact sophomore English classes. The treatment group received daily, explicit, rich vocabulary…

This article focuses on educational language practices as described by preschool teachers in Norwegian kindergartens in groups consisting of one- to three-year-old children. Research indicates a relationship between high-quality childcare and language development, yet there is a need for more research on educational practices in high-quality…

This study aimed to describe home literacy (HL) activities of Spanish-/English-speaking children of low-socioeconomic status backgrounds and examine the relationship between HL and performance on standardized assessments. Parents of 65 dual-language learners (DLLs) in kindergarten completed an HL questionnaire. Parents reported an average of 17…

Teacher preparation is complex in nature. Students in K-12 education comprise of an increasingly culturally and linguistically diverse population. Standards have significantly evolved with state and Common Core State Standards that now place a greater emphasis on academic discourse both in written and oral forms. To better prepare the next…

Bilingual children often show advanced executive functioning (EF) and false belief (FB) understanding compared to monolinguals. The latter has been attributed to their enhanced inhibitory control EF, although this has only been examined in a single study which did not confirm this hypothesis. The current study examined the relation of EF and…
