This emerging technology report delves into the role of ChatGPT, an OpenAI conversational AI, in language learning. The initial section introduces ChatGPT's nature and highlights its features, including accessibility, personalization, immersive learning, and instant feedback, which render it a valuable asset for language learners and educators…

This paper invites us to reconsider our usual understanding of infancy, no longer as something that passes but as "infantia." The Latin word "infantia," which is not easy to translate, means a lack of speech, a lack of eloquence, and also infancy, babyhood, and dumbness. Drawing on Barbara Cassin's works on the untranslatables,…

Young children can exploit the syntactic context of a novel word to narrow down its probable meaning. This is "syntactic bootstrapping." A learner that uses syntactic bootstrapping to foster lexical acquisition must first have identified the semantic information that a syntactic context provides. Based on the "semantic seed…

The ability to objectively quantify the complexity of a text can be a useful indicator of how likely learners of a given level will comprehend it. Before creating more complex models of assessing text difficulty, the basic building block of a text consists of words and, inherently, its overall difficulty is greatly influenced by the complexity of…

In this commentary, I discuss why, despite the existence of gradience in phonetics and phonology, there is still a need for abstract representations. Most proponents of exemplar models assume multiple levels of abstraction, allowing for an integration of the gradient and the categorical. Ben Ambridge's dismissal of generative models such as…

Bilingual environments are more complex than monolingual environments. To adapt to this complexity, bilingual infants may navigate their environment in fundamentally different ways than monolingual infants. Drawing from visual, social, and linguistic processing, in this article, I present evidence to suggest that bilingual and monolingual learners…

Theoretical approaches within the cognitive-interactionist framework (Long, 2015) have identified various aspects of L2 input and characteristics of instruction that predict learners' L2 outcomes. Such strategies of L2 teaching relate to shaping characteristics of communicative activities in which the L2 is embedded and modifying L2 input, L2…

Preverbal communication means any social behavior that occurs before children communicate verbally. Generally, these communicative behaviors are categorized into two ways: as behavior regulation (BR) or joint attention (JA) skills. BR, also referred to as requesting, involves the use of behaviors to gain something or receive assistance (Mundy et…

Scholars of language development have long been challenged to understand the development of functional categories. Traditionally, it was assumed that children's language development initially relies on lexical elements, while functional elements become accessible only at later periods; and that it is lexical growth which bootstraps grammatical…

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…

The visual-manual modality of sign languages renders them a unique test case for language acquisition and processing theories. In this commentary the authors describe evidence from signed languages, and ask whether it is consistent with Ambridge's proposal. The evidence includes recent research on collocations in American Sign Language that reveal…

Purpose: Most children with autism spectrum disorder (ASD) have below-age lexical knowledge and lexical representation. Our goal is to examine ways in which difficulties with social communication and language processing that are often associated with ASD may constrain these children's abilities to learn new words and to explore whether minimizing…

The Discontinuity Model (DM) described in this article proposes that adults can learn part of L2 morphosyntax twice, in two different ways. The same item can be learned as the product of generation by a rule or as a modification of a template already stored in memory. These learning modalities, which are often seen as opposed in language theory,…

The goal of this article is to make the case for a radical exemplar account of child language acquisition, under which unwitnessed forms are produced and comprehended by on-the-fly analogy across multiple stored exemplars, weighted by their degree of similarity to the target with regard to the task at hand. Across the domains of (1) word meanings,…

Naturalistic language and communication strategies (i.e., naturalistic teaching strategies) refer to practices that are used to promote the child's language and communication skills either through verbal (e.g., spoken words) or nonverbal (e.g., gestures, signs) interactions between an adult (e.g., parent, teacher) and a child. Use of naturalistic…
