Language is crucial for adapting to society, and learning different languages enhances human efficiency. Learning a second language involves acquiring any language in addition to one's native language. Second Language Acquisition (SLA) has two meanings, generally, it describes the process of learning a second language, and more specifically, it…

The past thirty years have shown a rise in models of language acquisition in which the state of the learner is characterized as a probability distribution over a set of non-stochastic grammars. In recent years, increasingly powerful models have been constructed as earlier models have failed to generalize well to increasingly complex and realistic…

In the first year of life, infants' speech perception becomes attuned to the sounds of their native language. This process of early phonetic learning has traditionally been framed as phonetic category acquisition. However, recent studies have hypothesized that the attunement may instead reflect a perceptual space learning process that does not…

Children learn words in a social environment, facilitated in part by social cues from caregivers, such as eye-gaze and gesture. A common assumption is that social cues convey either perceptual or social information, depending on the age of the child. In this review of research on word learning and social cues during early childhood, we propose…

The study of language acquisition has a long and contentious history: researchers disagree on what drives this process, the relevant data, and the interesting questions. Here, I outline the Starting Big approach to language learning, which emphasizes the role of multiword units in language, and of coarse-to-fine processes in learning. I outline…

Background: Children with communication disorders experience difficulty in one or more areas of articulation and speech, language, fluency, voice and social communication, and they work with speech-language pathologists (SLPs) to improve their communication. With the rise of adoption and use for mobile applications among special education and…

Despite different epistemologies and assumptions, all theories in second language (L2) acquisition emphasize the centrality of context in understanding L2 acquisition. Under the assumption that language emerges from use in context, the cognitivist approach focuses on distributions and properties of input to infer both learning objects and process…

While there is a growing body of research on second language acquisition (SLA) in children, adolescents, young and more mature adults, much remains to be explored about how adults in later life learn a new language and how good additional language learning is for them. Our goal in this article is to survey and evaluate what is known about the…

Purpose: In typical development, distributional cues--patterns in input--are related to language acquisition processes. Statistical and implicit learning refer to the utilization of such cues. In children with intellectual disability, much less is known about the extent to which distributional cues are harnessed in mechanisms of language learning.…

The work of L.S. Vygotsky was popularised in the West between two great waves of educational thought: constructivism and cognitivism. Reception was therefore colored by three metaphors introduced by Jerome Bruner: 'construction', 'scaffolding' and 'narrative'. Narratives were to be characterized by features we call SELF: Subjects, Expectancy and…

Dynamic systems theory (DST) is presented in this article as a suitable approach to research the acquisition of second language (L2) because of its close alignment with the process of second language learning. Through a process of identifying and comparing the characteristics of a dynamic system with the process of L2 learning, this article…

The present review explores the meaning of the term 'incidental' in light of how incidental learning is framed, conceptualized, and operationalized in second language (L2) vocabulary research. Three interpretations of incidental vocabulary learning that seem to appear recurrently in the literature are presented and discussed along with examples of…

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…

There is an exponential growth in the number of schools that offer American Sign Language (ASL) for foreign language credit and the different ASL curricula that were published. This study analyzes different curricula in its assumptions regarding language, learning, and teaching of second languages. It is found that curricula vary in their…

The author reviews some of the recent research on learning to read, and discusses two theories prevalent during the 1970s of the process of perception during mature reading--the Hypothesis Position and the Direct Perception Position. (KC)
