In this paper, I first provide a brief review of how scholars have conceptualized, tested, and elaborated aptitude frameworks relevant to second language (L2) speech learning. Subsequently, I introduce an emerging paradigm that assigns a fundamental role to domain-general auditory processing (i.e., having a good ear) in L1 speech acquisition and…

Despite earlier claims that language abilities are intact in individuals with Williams syndrome (WS), many studies have shown that language development is often delayed and atypical, that is, it develops in line with different cognitive abilities compared to typically developing populations. It is unclear, however, whether general cognitive…

Attempts to prevent language endangerment seem to have overlooked how families proceed in surrendering the language whose intergenerational transmission is their main responsibility. The present paper envisages language maintenance or loss from the vantage point that beliefs about language are the main referents of language use in the family in…

We investigated age-related decline in adult learning of Dutch as an additional language (Ln) in speaking, writing, listening, and reading proficiency test scores for 56,024 adult immigrants with 50 L1s who came to the Netherlands for study or work. Performance for all four language skills turned out to decline monotonically after an age of…

This study sought to contribute to the growing literature on third and subsequent language learning by establishing whether bilingualism has an effect on ability to learn a subsequent language, as indicated by a measure of language aptitude, the Defense Language Aptitude Battery (DLAB). Test results were obtained for 142 diplomatic officers in the…

Mathematical reasoning is now featured in the mathematics curriculum documents of many nations, but this necessitates changes to teaching practice and hence a need for professional learning. The development of children's mathematical reasoning requires appropriate encouragement and feedback from their teacher who can only do this if they recognise…

Among the new and multiple demands from contemporary society, framed in a global context of constant changes and advances, one of the most outstanding needs in recent years is the early acquisition of a second language. It is commonly known that, when starting the process of learning a second language or L2 being in adulthood, the results are not…

This longitudinal study involving 101 Dutch four- and five-year-olds charts indirect request (IR) and mental state term (MST) understanding and investigates the role that Theory of Mind (ToM) and general linguistic ability (vocabulary, syntax, and spatial language) play in this development. The results showed basic understanding of IR and MST in…

Background: Little is known about the nature, range and prevalence of different subgroups in language trajectories extant in a population from 4 to 11 years. This hinders strategic targeting and design of interventions, particularly targeting those whose difficulties will likely persist. Methods: Children's language abilities from 4 to 11 years…

Background: It is recognized that children from areas associated with socioeconomic disadvantage are at an increased risk of delayed language development. However, so far research has focused mainly on young children and there has been little investigation into language development in adolescence. Aims: To investigate the language abilities of…

This paper reports a quantitative study on gender differences in attitudes when learning oral skills via technology. The study was conducted at Tafila Technical University, Jordan, with 70 female and 30 male students, to find out if female students are better and faster in learning a language than male. Specifically, it seeks to investigate…

The presence or absence of clinically delayed language development prior to 3 years of age is a key, but contentious, clinical feature distinguishing autism from Asperger's disorder. The aim of this study was to examine language processing in children with high-functioning autism (HFA) and Asperger's disorder (AD) using a task which taps lexical…

This research aims to develop instruments to assess language development in under-3s and the adult interventions that support it. After an extensive literature search, observations were conducted in 17 groups of children spread over two day-care centres. In total 42 children were observed during a 30-minute slot and 25 adults during a half day.…

The dissertation project is a study of how childrens' increasingly skillful use of certain language forms ("stance forms") help them to more effectively perform culturally salient social identities in discourse. Although scholars have long claimed that language use helps to position speakers in terms of socially recognizable identities,…

Typically language development in children closely coincides with development in many other areas. This makes it difficult to determine whether observed correlations are coincidental or causal in nature. The three studies presented here explore these relationships by looking at two populations of learners who are delayed in exposure to English,…
