The study investigates the effect of the perception of text and task difficulty on adults' performance in reading tests in L1 and L2. The relationship between the following variables is studied: (a) readers' perception of text and task difficulty in L1 and L2 measured in a self-reported post-task questionnaire, (b) the number of correct answers to…

Source-based writing is a complex and frequently occurring task type in postsecondary education. While a large body of research now exists investigating source-based student writing, few studies have used corpus-based methods to investigate L1 student performance on source-based writing tasks and to connect this performance to the holistic quality…

This study examined the impact of the manipulated task complexity (Robinson 2001a, 2001b, 2007, 2011; Robinson & Gilabert, 2007) on second language (L2) speech comprehensibility. I examined whether manipulated task complexity (a) impacts L2 speech comprehensibility, (b) aligns with L2 speakers' perception of task difficulty (cognitive…

This study examined the sources of reading comprehension difficulties in English language learners (ELLs). The characteristics of ELL poor comprehenders were compared to their English as a first language (EL1) peers. Participants included 124 ELLs who spoke Chinese as an L1 and 79 EL1 students. Using a regression technique based on age, non-verbal…

Multiple test tasks are available for assessing L2 collocation knowledge. However, few studies have investigated the characteristics of a variety of recognition and recall tasks of collocation simultaneously, and most research on L2 collocations has focused on verb-noun and adjective-noun collocations. This study investigates (1) the relative…

Applied linguistics may benefit from a morphological complexity measure to get a better grip on language learning problems and to better understand what kind of typological differences between languages are more important than others in facilitating or impeding adult learning of an additional language. Using speaking proficiency scores of 9,000…

The present study examined the effect of L1 domain-relevant knowledge on L2 reading comprehension texts among student teachers of ELT (N = 90), drawn from a population of 270 student teachers studying at an undergraduate program in some state universities in Iran. A proficiency test was applied to control language proficiency of students. Among…

Differential item functioning (DIF) assessment is key in score validation. When DIF is present scores may not accurately reflect the construct of interest for some groups of examinees, leading to incorrect conclusions from the scores. Given rising immigration, and the increased reliance of educational policymakers on cross-national assessments…

Background: Many children with specific language impairment (SLI) in sentence comprehension. These deficits are usually attributed to limitations in the children's understanding of syntax or the lexical items contained in the sentences. This study examines the role that extra-linguistic factors can play in these children's sentence comprehension.…

Background: To date there is limited information documenting growth patterns in the narratives of bilingual children with and without primary language impairment (PLI). Aims: This study was designed to determine whether bilingual children with and without PLI present similar gains from kindergarten to first grade in the macro- and microstructure…

This study investigated which level of graded reader was most appropriate for Chinese-speaking learners of various English abilities and whether there were significant differences in comprehension and vocabulary acquisition when different English proficiency (EP) groups read texts of varying difficulty levels. Eight-two senior high school students…
