The study investigates whether Italian verbal inflectional morphology is associated with inhibitory control skills after controlling for receptive vocabulary and verbal working memory. A sample of Italian preschoolers aged 4;0 to 6;0 was assessed using a standardized inhibitory control task tapping two different inhibitory skills (response…

Investigations have been too limited and inconclusive to find out whether written corrective feedback improves grammatical accuracy of learners. This study aimed at investigating the comparative effects of direct and indirect corrective feedback on short-term and long-term retention of the subject-verb agreement by Iranian EFL writers. The design…

We investigate sensitivity to island constraints in English native speakers and Najdi Arabic learners of English, examining (1) whether second language (L2) learners whose native language (L1) does not instantiate overt "wh"-movement are sensitive to island constraints and (2) the source of island effects. Under a grammatical account of…

Purpose: Little is known about the relationship between discourse comprehension and production in traumatic brain injury (TBI), especially for spoken language. This study examined to what extent narrative discourse comprehension accounts for narrative discourse production outcomes (story grammar, story completeness). A secondary aim was to…

Background: The comprehension profile of people with agrammatism is a debated topic. Syntactic complexity and cognitive resources, in particular phonological short-term memory (pSTM), are considered as crucial components by different interpretative accounts. Aim: To investigate the interaction of syntactic complexity and of pSTM in sentence…

This dissertation examines the relative effects of phonetic salience and phonological prominence on speech sound processing. Three test cases, respectively, investigate the processing of consonants versus vowels by speakers of German, Hebrew, and Amharic; the processing of aspirated versus unaspirated stops by speaker of Spanish and Thai; and the…

Representing the base-10 structure of numbers is a challenging cognitive ability, unique to humans, but it is yet unknown how precisely this is done. Here, we examined whether and how literate adults represent a number's full syntactic structure. In 5 experiments, participants repeated number-word sequences and we systematically varied the order…

This study investigates the role of recursive language and working memory (WM) in second-order false belief skills in Danish-speaking children with autism spectrum disorder (ASD; n = 62; 8 females) and typical development (n = 41; 15 females), ages 6-16. Second-order false belief skills correlated with receptive grammar, vocabulary, and age;…

Lexical ability, an umbrella term to cover various knowledge and skills pertaining to words in print, is a key component in reading comprehension. Little is known how different facets of lexical ability jointly contribute to L2 reading comprehension and how the contributions may differ between higher- and lower-proficiency L2 learners. This study,…

This study aimed to investigate the effect of visual input enhancement (VIE) on the comprehension of reading texts and the learning of two grammatical forms: English relative clauses and articles. Individual learners' working memory (WM) capacity was also tested to explore its impact on the effectiveness of VIE. A total of 48 Korean college…

We report on a conceptual replication of Révész (2012) in order to investigate the idea whether learners provided with recasts do engage in different kinds of behavioral engagement as a function of their working memory and if/how this engagement comes to bear on performance on different measures. Engagement with recasts was measured through a…

The deficit in verbal working memory (vWM) skills has been frequently reported in children with developmental language disorder (DLD) and may contribute to their problems in language. This study aimed to compare the phonological short-term memory (pSTM) and linguistic skills between Persian-speaking children with DLD and typical language…

Background and aims: Previous studies suggest that syntactic development in children with intellectual disabilities (ID) is positively correlated with verbal short-term memory (VSTM). This study investigated the characteristics of syntactic development and their relationships of VSTM in children with ID based on type. Methods: The participants…

This study investigates the interpretation of object-initial sentences in German-speaking children. We addressed the following questions: (1) Which morphosyntactic cues do children deploy to process object-initial sentences? (2) Which executive function (EF) abilities support them during this task? This study examined the effect of case and number…

The present dissertation reports two experiments that examine implicit and explicit language learning methods and their impacts on early vocabulary, grammar, and phonological acquisition, in addition to working memory, proactive/reactive control, and fluid intelligence, as well as learner motivation. Experiment 1 investigated adult L2 acquisition…
