According to the Interface Hypothesis (IH) (e.g., Tsimpli & Sorace 2006; Sorace 2011), external interfaces are more challenging for L2 learners than internal interfaces. It is not clear, however, if linguistic phenomena associated with external interfaces are necessarily problematic and if internal interfaces are necessarily unproblematic. In…

This article draws on an approach that conceptualizes L2 learning difficulty in terms of implicit and explicit knowledge. In a study with first language Mexican Spanish university-level learners (n = 30), their teachers (n = 11), and applied linguistics experts (n = 3), we investigated the relationship between (a) these groups' difficulty…

This study examined Italian 7- to 9-year-olds' understanding of the connective "but" when used to relate two events in sentences embedded in short stories. Performance was largely accounted for by the cognitive complexity of the sentence that included the connective and the salience of its meaning (confirmed in a second study with…

While there is a plethora of research on pronunciation problems of EFL learners with different L1 backgrounds, published empirical studies on syllabification errors of Iraqi Kurdish EFL learners are scarce. Therefore, to contribute to this line of research, the present study set out to investigate difficulties of this group of learners in the…

Based on a prior study by Chen and Truscott, the present study investigated the possible effects of repetition (repeated exposure) and L1 lexicalization on the incidental acquisition and retention of 10 English target words by 90 Persian-speaking EFL learners at an Iranian university. Seven aspects of vocabulary knowledge were measured, including…

This paper has studied the question formation techniques used by the Saudi students at Bisha University. It addresses the problems faced by the students in forming questions in English. The study has identified that a large number of the students suffer from the lack of proper grammar rules in forming various types of interrogative sentences and…

The visual complexity of orthographies varies across writing systems. Prior research has shown that complexity strongly influences the initial stage of reading development: the perceptual learning of grapheme forms. This study presents a computational simulation that examines the degree to which visual complexity leads to grapheme learning…

The purpose of this study was to determine whether an eighth grade state-level math assessment contained items that function differentially (DIF) for English Learner students (EL) as compared to English Only students (EO) and if so, what factors might have caused DIF. To determine this, Differential Item Functioning (DIF) analysis was employed.…

Purpose: The purpose of this study was to examine sentence-recognition performance for a large, diverse group of nonnative speakers of English on the recently developed Basic English Lexicon (BEL) sentence materials and to determine whether BEL sentence lists are equated in difficulty for this population. Method: The BEL sentences were presented…

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…
