The present study investigates the impact of meaningful input on L2 learners' vocabulary use and their fluency in oral performance (immediate and repeat tasks), as well as whether the effects are mediated by learners' prior vocabulary knowledge and working memory. Ninety university students learning English as a foreign language were randomly…

Grammar competition has been proposed as a model for second language (L2) acquisition. Variational Learning provides a framework within which to investigate the idea of grammar competition as the model requires a marriage of quantitative properties of the input with Universal Grammar. A diachronic variational model of grammar competition is…

Chapelle (2003) proposed three general types of input enhancement that help L2 learners "acquire features of the linguistic input that they are exposed to during the course reading or listening for meaning" (p. 40): input salience, input modification, and input elaboration. In 2010, Cárdenas-Claros and Gruba argued that Chapelle's…

Inequality often appears in linked pairs of variables. Examples include schooling and income, income and consumption, and wealth and happiness. Consider the famous words of Veblen: "wealth confers honor." Understanding inequality requires understanding input inequality, outcome inequality, and the relation between the two--in both…

Neuropsychological case-studies suggested that dates and encyclopedic numbers may be processed differently than unknown numbers. However, this issue was seldom investigated in healthy participants. Therefore, it is unclear whether known dates are read like words (as lexical items), or like numbers (each position strictly defines digits' values in…

Multimedia input can enhance vocabulary learning in the context of learning English as a foreign language (EFL). Drawing upon a mixed method, this study explores the potential of multimedia input in vocabulary learning. EFL vocabulary learning was assessed under four input conditions ("definition + word information + video, definition + word…

How does parental causal input relate to children's later comprehension of causal verbs? Causal constructions in verbs differ across languages. Turkish has both lexical and morphological causatives. We asked whether (1) parental causal language input varied for different types of play (guided vs. free play), (2) early parental causal language…

Traditionally, the exogenous control of gaze by external saliencies and the endogenous control of gaze by knowledge and context have been viewed as competing systems, with late infancy seen as a period of strengthening top-down control over the vagaries of the input. Here we found that one-year-old infants control sustained attention through head…

One of the key commitments of the Community College Research Initiatives (CCRI's) STEM Transfer Partnership (STP) program is to transform STEM transfer pathways and improve outcomes for students from low-income backgrounds using student input. Student input is an essential element in institutional transformation for student success but the process…

Despite the fact that in most communities interaction occurs between the child and multiple speakers, most previous research on input to children focused on input from mothers. We annotated recordings of Sesotho-learning toddlers living in non-industrial Lesotho in South Africa, and French-learning toddlers living in urban regions in France. We…

Infants experience language in rich multisensory environments. For example, they may first be exposed to the word applesauce while touching, tasting, smelling, and seeing applesauce. In three experiments using different methods we asked whether the number of distinct senses linked with the semantic features of objects would impact word recognition…

Interpreting a sentence can be characterized as a rational process in which comprehenders integrate linguistic input with top-down knowledge (e.g., plausibility). One type of evidence for this is that comprehenders sometimes reinterpret sentences to arrive at interpretations that conflict with the original language input. Does this reflect a…

This study examined the extent to which early intervention (EI) speech-language pathologists (SLPs) use and recommend language input strategies for caregivers of children with language delays and the child factors associated with these decisions. Participants included 213 SLPs who completed an online survey. Wilcoxon signed-rank tests, Friedman's…

This study investigates the effects of input-based and output-based instructions on the acquisition of second language (L2) request modifiers. Four intact classes were randomly assigned to textual enhancement (TE), input flooding (IF), output-based instruction (OI), and control (CO) groups. The TE group watched some captioned videos on requests…

In acquiring a native language, the input children receive, to an unneglectable extent, shapes the rate of acquisition and the ultimate achievement. This in turn has cascading effects on many aspects of later development, including but not limited to language. Providing optimal input for early language development, therefore, is of major interest…
