Purpose: We examined receptive verb knowledge in 22- to 24-month-old toddlers with a dynamic video eye-tracking test. The primary goal of the study was to examine the utility of eye-gaze measures that are commonly used to study noun knowledge for studying verb knowledge. Method: Forty typically developing toddlers participated. They viewed 2…

This study examines the quantity and quality of child-directed speech across household activities in a socioeconomically diverse sample of Argentinian Spanish-speaking children, an understudied population. Thirty children (mean: 14.3 months) and their families were audio-recorded for four hours. The middle two hours were transcribed and analysed…

This study examined the differences and similarities among the writing of three types of developmental English and advanced ESL United States community college students, comparing the writing of resident English learners (RL2), whose home language was not English but who attended United States public schools for five years or more, to that of…

Purpose: Several studies have reported that "useful speech" at 5 years of age predicts outcomes in individuals with autism spectrum disorder (ASD), but this skill has been vaguely defined. This study investigates which specific aspects of expressive language in children with ASD best predict adult language and communication outcomes.…

This study was conducted to identify Iranian EFL teachers' perceptions regarding the most serious written errors made by young adult EFL learners, along with the most effective types of written corrective feedback to deal with them. Data were collected from 253 Iranian EFL teachers through a questionnaire made by the researchers and were analyzed…

For this study, 11 children with moderate to severe autism spectrum disorder (ASD) were given directives containing prepositions in three cue conditions: (a) spoken alone, (b) a short video clip along with spoken cues, and (c) a sequence of three graphic symbols accompanied by spoken cues. Participants followed directives significantly more…

This study aimed to investigate the production of stress in English compound nouns and phrasal verbs by L1 Thai learners. Based on the Interlanguage Hypothesis (Corder, 1982; Selinker, 1972), it was hypothesized that (1) there is a positive relationship between English proficiency levels and accuracy in stress assignment in compound nouns and…

First-order theory of mind (ToM) development has shown to conform to a Guttman scale, with desire reasoning developing before belief reasoning. There have been attempts to test for internal consistency and scalability in advanced ToM, but not over a broad age range and only with a limited set of tasks. This 2-year longitudinal study (N = 155;…

The present study investigates collocational profiles that appear in the English textbook series for Vietnamese students from elementary to high school grades by identifying how the series covers collocations in terms of frequency and how the mode of collocation presentation aligns with recommendations in the existing literature. A total of 30,005…

While semantic and syntactic properties of verb meaning can impact the success of verb learning at a single age, developmental changes in how these factors influence acquisition are largely unexplored. We ask whether the impact of syntactic and semantic properties on verb vocabulary development varies with age and language ability for toddlers…

This research addresses implicit learning of temporal meanings in English by adult non-native readers of German, a language without morphosyntactic imperfective aspect. Twenty-four learners from mixed first languages participated in a norming study assessing unenhanced aspect awareness. Then, in a second experiment, 91 native-German learners…

Becoming productive with grammatical categories is a gradual process in children's language development. Here, we investigated this transition process by focusing on Turkish causatives. Previous research examining spontaneous and elicited production of Turkish causatives with familiar verbs attested the onset and early stages of productivity at…

English ditransitive verbs show a complex alternation between the double object construction (DOC, (1)) and prepositional object datives (POD, (2)). This dissertation examines the acquisition, representation, and learnability of the dative alternation among L2 English learners, presenting experimental data from participants with L1 backgrounds of…

When reading scientific text, readers must draw inferences when the author does not make relations explicit; readers also need to pick up on causal relations that the author "does" make explicit. We collected think-aloud protocols from 86 undergraduate biology students reading 7 brief, illustrated passages about the immune system. After…

The difficulties in learning skills that deaf and hard of hearing students encounter stem from morphology and syntactic morphology (morpho-syntax) and it is clear that there are limited studies related to these. In this study, it is aimed at examining hearing and deaf and hard of hearing students' morpho-syntactic actions which are compatible with…
