This article explores how leading textbook authors select and instruct vocabulary in beginner and intermediate Chinese textbooks used in the United States. Leading textbook authors were approached; subsequently; four authors completed interviews with pre-designed questions. Grounded theory methodology was used to analyse the interviews, and their…

While it is known that heritage speakers diverge from the homeland baseline, there is still no consensus on the mechanisms triggering this divergence. We investigate the impact of two potential factors shaping adult heritage language (HL) grammars: (1) cross-linguistic influence (CLI), originally proposed for second language acquisition (SLA), and…

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…

The "wanna" facts are a classic Poverty of Stimulus (PoS) problem: "Wanna" is grammatical in certain contexts ("Who do you want PRO to play with?") but not others ("Who do you want who[strikethrough] to play with you?"). On a standard analysis, "contraction" to "wanna" is blocked by some…

This study examines the effect of enhanced input of lexical chunks on the performance of Arabic-speaking English learners' writings. Lexical chunks, containing their forms, meanings, and functions, stored and recovered as a single component in brains, may alleviate language processing problems and increase language proficiency. The research…

This research paper presents a quasi-experimental empirical study investigating the effects of structured input and structured output tasks on the acquisition of English causative forms. This research is framed on VanPatten's (1996) input processing theory. The grammatical form chosen for this investigation is affected by a processing strategy…

This article examines factors that promote active multilingualism. For this purpose, the "Peabody Picture Vocabulary Test" was used with 48 children. Their results were linked to a parental questionnaire designed to evaluate the children's linguistic input in their immediate environment. The study shows that, besides a minimum amount of…

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…

Purpose: This paper investigates the accuracy order of grammatical morphemes followed by Saudi EFL learners. The major aim of the research was to reveal the pattern of grammatical morpheme acquisition of the participants, and to compare it against the Natural Order Hypothesis (NOH) as stated by Krashen (1977). The different factors that affected…

This study explores the effects of extensive audio-visual input with three captioning modes -- unenhanced captions, textually enhanced captions, and no captions -- on learning a variety of L2 grammatical constructions and examines the effects of three learnability factors: construction type, frequency, and recency. A total of 112 participants…

The present study investigates whether textual enhancement had any effects on grammar learning (tag questions) and reading comprehension, and whether the types of tag question contributed to the benefits of textual enhancement. The study employed a pretest--posttest design with three treatment sessions. The target forms were English tag questions,…

The current project longitudinally investigated the extent to which first-year Japanese university students developed their second language (L2) oral ability in relation to increased input in foreign language classrooms. Their spontaneous speech was elicited at the beginning, middle and end of one academic year, and then judged by linguistically…

This study examines the effectiveness of the provision of specific input on the use of verb conjugation and tenses to preparatory students at Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. This is a well-documented grammatical issue for native Arabic speakers, and was undertaken due to this factor, as well as the students under…

The two main components of Processing Instruction (PI) are Explicit Information (EI) and Structured Input (SI). Most researchers have concluded that the SI is more responsible for learner gains than the EI (Benati, 2004a, 2004b; VanPatten & Oikennon, 1996; Wong, 2004). However, some researchers have found that EI does significantly impact…

This article reports the findings of a study in which we investigated the possible effects of word order on the acquisition of case marking. In linguistic typology (e.g. Greenberg, 1963) a very strong correlation has been shown between dominant SOV (subject object verb) word order and case marking. No such correlation exists for SVO (subject verb…
