Research on "parentese," the acoustically exaggerated, slower, and higher-pitched speech directed toward infants, has mostly focused on maternal contributions, although it has long been known that fathers also produce parentese. Given recent societal changes in family dynamics, it is necessary to revise these mother-centered models of…

Why do infants learn some words earlier than others? Many theories of early word learning focus on explaining how infants map labels onto concrete objects. However, words that are more abstract than object nouns, such as "uh-oh," "hi," "more," "up," and "all-gone," are typically among the first to…

This paper contributes to a research program within extensive reading (ER) and "Reading in a Foreign Language" using corpora to simulate ER input to develop vocabulary through incidental learning to 9,000 words. This helps researchers/teachers evaluate ER. If corpora indicate no 'pathway' from smaller to larger vocabulary sizes through…

This study evaluates the potential for incidentally learning early reading vocabulary through the extensive viewing (EV) of children's movies/television with subtitles. Recent research has investigated how much exposure to important vocabulary EV and extensive reading (ER) provides. Investigations compute the number of repetitions of target…

It is commonly accepted that educators who prepare to teach materials to meet student needs should cover all skills in English, such as speaking, listening, reading, and writing with additional grammar and vocabulary according to the level of students. Because technology has developed rapidly, educators can design technologically friendly teaching…

In order for children to understand and reason about the world in an adult-like fashion, they need to learn that conceptual categories are organized in a hierarchical fashion (e.g., a dog is also an animal). While children learn from their first-hand observation of the world, social knowledge transmission via language can also play an important…

The importance of input on language learning cannot be overstated. One method of providing input to learners at a level that is appropriate for them is called extensive reading, in which learners read an abundance of texts. In practice, for learners of English as a second or foreign language, these texts are often books that have been written and…

Semantic variables enable L2 researchers and materials creators to quantify and control the effects of meaning on cognition. However, in recent years, many variables have been normed and published. Parsing the methods employed in norming this myriad of variables and which disparate theories informed their creation can be an opaque and arduous…

This study examines second language (L2) learners' perspectives regarding the affordances and challenges of using the Data-Driven Learning (DDL) to identify the properties of near-synonymous words. Employing a convergent mixed-method design, this study deciphers the perceptions of 40 undergraduate L2 learners majoring in English language teaching.…

For languages to survive as complex cultural systems, they need to be learnable. According to traditional approaches, learning is made possible by constraining the degrees of freedom in advance of experience and by the construction of complex structure during development. This article explores a third contributor to complexity: namely, the extent…

Age of acquisition (AoA) is a measure of word complexity which refers to the age at which a word is typically learned. AoA measures have shown strong correlations with reading comprehension, lexical decision times, and writing quality. AoA scores based on both adult and child data have limitations that allow for error in measurement, and increase…

English-medium instruction (EMI) is gaining popularity among EFL higher education institutions. However, not all EMI programs provide the same English immersion as those in the Anglosphere. The researcher targeted English medium university textbooks as a research focus, since they are first and foremost learning material of specialist knowledge…

Corpus-based data-driven learning (DDL) is an inductive instructional approach using computer-generated concordances. It provides students with the opportunity to analyze different language forms across contexts found in the concordance output. The idea of engaging students to discover the language rules and patterns from authentic learning…

This study builds on prior research on second language (L2) Spanish psych verbs, which has centered on morphosyntactic properties, by examining their syntactic distribution, which relies on lexical semantic knowledge. The fact that certain forms are licensed for some verbs, but not others, is the result of an underlying lexical semantic difference…

The words in children's language learning environments are strongly predictive of cognitive development and school achievement. But how do we measure language environments and do so at the scale of the many words that children hear day in, day out? The quantity and quality of words in a child's input are typically measured in terms of total amount…
