Purpose: Persons with aphasia (PWAs) have been shown to have impaired attention skills that may interfere with their ability to successfully participate in speech and language therapy. Fluctuations in attention can be detected using physiological measures such as electroencephalography (EEG), but these measures can be impractical for clinical use.…

Internal error monitoring as reflected by the error-related negativity (ERN) component can give insight into the process of learning a second language (L2). Yet, early stages of learning are characterized by high levels of uncertainty, which obscures the process of error detection. We examine how uncertainty about L2 syntactic representations,…

The language we use over the course of conversation changes as we establish common ground and learn what our partner finds meaningful. Here we draw upon recent advances in natural language processing to provide a finer-grained characterization of the dynamics of this learning process. We release an open corpus (>15,000 utterances) of extended…

Common tests of morphological awareness measure both morphology and syntax by requiring participants to fit words and pseudowords into sentences by adding or removing affixes. We report the results of a study testing a new word level task. College students viewed transparent words (without phonological or orthographic shifts) and used a keyboard…

Reading texts may serve as a vital source of informational content and language knowledge for second language (L2) learners, which is known as the dual relevance of L2 reading (Han & D'Angelo, 2009). Text complexity, however, influences the two, determining to a great extent whether the dual outcome is attainable. Drawing on Complex Dynamic…

Mandarin requires neither determiners nor morphological inflections, which casts doubt on Mandarin-speaking children's ability to use function words as a syntactic bootstrapping tool to identify the form class of a new word. This study examined 3- and 5-year-old Mandarin learners' ability to use function words to interpret new words as either…

An extensive body of research has investigated the role of syntactic complexity in gauging the linguistic complexity of reading texts, particularly for the purpose of determining their grade appropriateness. However, little such research has focused on adapted teaching materials for English as a foreign language (EFL) contexts, and to date there…

Purpose: Research in the cognitive and neural sciences has situated predictive processing--the anticipation of upcoming percepts--as a dominant function of the brain. The purpose of this article is to argue that prediction should feature more prominently in explanatory accounts of sentence processing and comprehension deficits in developmental…

Purpose: This study provided reference data and examined psychometric properties for clausal density (CD; i.e., number of clauses per utterance) in children between ages 4 and 9 years from the database of the Edmonton Narrative Norms Instrument (ENNI). Method: Participants in the ENNI database included 300 children with typical language (TL) and…

Based on data from numerous languages, such as English, Frisian, and Danish, Merchant (2001) proposes the "preposition stranding generalization" (PSG), which states that only languages that allow preposition stranding under wh-movement also allow preposition stranding under sluicing. The availability of this generalization has been the…

This paper aims to discuss old and contemporary perspectives in understanding language acquisition taking into account the neural theory of language. Discussing a recent theory by Kuhl (2010), neural substrates of first language learning will be put forward (Berwick et al., 2013). Neural substrates of phonetic learning, word learning, sentence…

Children with autism spectrum disorder often have significant language delays. But do they learn language differently than neurotypical toddlers? We compared the lexical skills of 64 preverbal and minimally verbal children with autism spectrum disorder to 461 vocabulary-size-matched typically developing toddlers. We also examined social features…

Purpose: The aim of this study was to extract key learning from intervention studies in which qualitative aspects of dosage, "dose form," have been examined for children with developmental language disorder (DLD)--in vocabulary, morphosyntax, and phonology domains. This research paper emerged from a pair of systematic reviews, aiming to…

The objectives of this study were to explore foreign tourists' responses to Thai English, a variety of English emerging in Thailand, in terms of comprehensibility, and to identify the linguistic features that made Thai English incomprehensible. One hundred international tourists in Bangkok from four regions including East Asia, Southeast Asia,…

In this article, we propose a reconceptualization of the principles and parameters (P&P) framework. We argue that in lieu of discrete parameter values, a parameter value exists on a gradient plane that encodes a learner's confidence that a particular parametric structure licenses the utterances in the learner's linguistic input. Crucially,…
