The goal of this paper is to tease apart two approaches to the source of children's consistent scope assignment in negative sentences containing logical connectives: the Semantic Subset Principle and the Semantic Subset Maxim. Previous developmental work has observed that four- to six-year-old children across languages have difficulty with…

Very few studies have investigated second language (L2) knowledge of word parts. The present study was set to measure L2 recognition of 35 English prefixes and the factors that might predict scores. The form and meaning sections of Sasao and Webb's Word Part Levels Test were administered to 152 Arabic learners of English as a foreign language…

aaaPlural marking differs across languages. Some must mark plurality using an overt morpheme (e.g. English, Russian), while others mark it optionally (e.g. Korean) or lack an explicit plural morpheme (e.g. Chinese). This crosslinguistic difference in plural marking has received much attention in research exploring language transfer in the context…

Word learning in a second language (L2) is a complex process, which is affected by learner-related (e.g., morphological awareness) and language-related (e.g., word semantic transparency) factors. Morphological awareness is learners' sensitivity to the morphological structure of printed words, and semantic transparency is the degree to which…

As one type of the most extensively used sentences, English questions are must-learn grammatical structures for learners of English as a foreign language (EFL). However, it is commonly seen that English learners across proficiency levels produce ungrammatical English questions. To determine the source of learners' erroneous production, we…

This study investigates the effects of motivation and structured input on the acquisition of English past tense regular forms. The role of motivation in the positive effects generated by processing instruction has been investigated in one previous study (Farhat & Benati, 2018). However, more research is needed to generalize the initial…

This research paper analyzes the extent to which Arabic-speaking EFL learners are aware of the English plural morphemes and whether they are able to recognize them in context. The study also investigates whether the participants' English proficiency level may play a role in their ability to recognize these morphemes. For the purpose of the study,…

This study investigated the learnability of multiple word knowledge aspects and the relationship between the word knowledge aspects. A total of 261 Thai high school students were measured on receptive and productive word knowledge aspects: word parts, the form-meaning link, and collocations. The current findings indicated that word parts are…

Purpose: This single-case study examines a complexity approach to target selection in grammatical intervention in three children with varying levels of mastery of tense and agreement. Specifically, we examine whether targeting a complex tense and agreement grammatical structure (auxiliary BE in questions) leads to generalization to other less…

The study investigates to what extent English as a second language (ESL) learners develop explicit and automatised explicit knowledge of two target-forms (third person singular 's' and future conditional if-clause) after input and output based instruction and whether learning effects differ depending on the target forms. The study follows a…

Morphological analysis and incidental learning are two vocabulary learning strategies that language learners may use in order to acquire the meanings of new words. To date, however, few studies have compared the effectiveness of these two strategies. Hence, the current study was carried out to compare the effect of morphological analysis and…

This current study aimed to investigate the influence of derivational and inflectional morphological awareness on the writing of undergraduate students studying English as a Foreign Language. They were divided in to two groups and each group comprised 200 advanced EFL learners. Explicit morphological instructions were given to group two in the…

This study investigates the effect of morphological treatment on morphological awareness and reading comprehension skill in a foreign language teaching. Experimental design was used in this study which was conducted with 74 freshmen who are studying at Translation and Interpreting Department. Following the Oxford Quick Placement Test and Nation's…

It has been well learnt that a large number of Arab EFL learners encounter a considerable degree of complexity in the use of tense and aspect as fundamental components of the English language. Such a degree of difficulty is perceived and experienced by those learners at their different levels of learning English starting at the primary level up to…

This study aims to clearly diagnose EFL "students' writing strengths and weaknesses." I adapted a diagnostic framework which comprises multiple writing components associated with three main dimensions of second language writing. The essays of 304 English learners who enrolled in an English language program were double-rated by 13…
