Washoe, the chimpanzee pioneer who learned aspects of American Sign Language, died in October 2007. In reviewing her life and accomplishments, this article focuses on Washoe's status as an ape and a person, and on the role of emotion in language learning and language use. It argues that Washoe's legacy stems not from the number of ASL signs she…

Participants (aged 5-6 yrs, 9-10 yrs and adults) rated (using a five-point scale) grammatical (intransitive) and overgeneralized (transitive causative) uses of a high frequency, low frequency and novel intransitive verb from each of three semantic classes [Pinker, S. (1989a). "Learnability and cognition: the acquisition of argument structure."…

Fundamental questions in cognitive science concern the origins and nature of the units that compose visual experience. Here, we investigate the capacity to individuate and store information about non-solid portions, asking in particular whether free-ranging rhesus monkeys ("Macaca mulatta") quantify portions of a non-solid substance presented in…

This study reports results of a randomized controlled trial aimed at joint attention (JA) and symbolic play (SP) in preschool children with autism, with prediction to language outcome 12 months later. Participants were 58 children (46 boys) with autism between 3 and 4 years of age. Children were randomized to a JA intervention, an SP intervention,…

Play is a significant medium for children's literacy development. As children engage in play activities, they are given opportunities and the motivation to show what they already know about reading and writing systems. Previous literature has shown that a literacy-rich environment increases the number of literacy activities available through play.…

Purpose: The aim of this study was to investigate the language outcomes of 7-year-old children with and without a history of late language emergence at 24 months. Method: One hundred twenty-eight children with a history of late language emergence (LLE) at 24 months and 109 children with a history of normal language emergence (NLE) at 24 months…

Despite arguments for the relative ease of learning common noun meanings, semantic development continues well past the early years of language acquisition even for names of concrete objects. We studied evolution of the use of common nouns during later lexical development. Children aged 5-14 years and adults named common household objects and their…

We found that infant gaze following and pointing predicts subsequent language development. At ages 0 ; 10 or 0 ; 11, infants saw an adult turn to look at an object in an experimental setting. Productive vocabulary was assessed longitudinally through two years of age. Growth curve modeling showed that infants who gaze followed and looked longer at…

This article seeks to illuminate the degree of position-based variation observed in the acquisition of new segments in a second language and to explain such variability as the consequence of phonetic constraints; this approach contrasts with much previous research that has used typological markedness to the same end. Specifically, it is proposed…

Embodied theories of cognition hold that mentally representing something "red" engages the neural subsystems that respond to environmental perception of that colour. This paper examines whether implicit perceptual information on object colour is represented during sentence comprehension even though doing so does not necessarily facilitate task…

This study seeks to uncover the characteristics of foreign language instructors' discourse styles implemented in the classroom when teaching students the target language. Foreign language classrooms are unique to academia because the teachers of the language, depending on whether they are native or non-native speakers of the target language,…

"The Analysis of Verbal Behavior" ("TAVB") publishes experimental and theoretical papers relevant to a behavioral analysis of language. Normand, Fossa, and Poling (2000) reviewed the published studies in "TAVB" across several dimensions and found that despite the growth of the journal, most articles published in "TAVB" from 1982 to 1998 were…

Speechreading is a visual communicative skill for perceiving speech. In this study, we tested the effects of speech experience and deafness on the speechreading neural network in normal hearing controls and in two groups of deaf patients who became deaf either before (prelingual deafness) or after (postlingual deafness) auditory language…

Research over the past several decades has provided insight into the processes that govern early brain development and how those processes contribute to behavior. In this article, the authors provide an overview of early brain development beginning with a summary of the prenatal period. They then turn to postnatal development and examine how brain…

Two experiments explored the neural mechanisms underlying the learning and consolidation of novel spoken words. In Experiment 1, participants learned two sets of novel words on successive days. A subsequent recognition test revealed high levels of familiarity for both sets. However, a lexical decision task showed that only novel words learned on…
