Purpose: Assessing whether a book is relevant or suitable for use in teaching materials is not an easy and haphazard matter, various methods and theories have been offered by researchers in studying this matter. Taking a study of the context of textbooks, researchers found the urgency that textbooks are a foundation for education, socialization…

Agreement asymmetry is one of the significant linguistic phenomena that Arab and Western linguists (Ghaly, 1995; Parkinson, 1995; Benmamoun, 1998; Collins, 2001; Dayf, 1986) and Aoun, 1994) have tried to account for within the framework of the Government and Binding theory. They focused upon the number asymmetry in different varieties in Arabic.…

We investigate concrete acquisition theories for a derived approach to linking theory development and explore to what extent two prominent linking theories in the syntactic literature--UTAH and rUTAH--can be derived from the data that English-learning children encounter. We leverage a conceptual acquisition framework that specifies key aspects of…

The objective of this study was to examine the development of derivational morphological structures in the productive language of Kuwaiti Arabic (KA)-speaking children. Participants were 512 typically developing Kuwaiti children aged 3;0 years to 7;11 years (243 boys and 269 girls). Five age groups at 1-year intervals were tested; each group was…

Using computational simulations, this work demonstrates that it is possible to learn a systematic relation between words' sound and their meanings. The sound-meaning relation was learned from a corpus of phonologically transcribed child-directed speech by using the linear discriminative learning (LDL) framework (Baayen, Chuang, Shafaei-Bajestan,…

Children's understanding of passives of certain mental state predicates appears to lag behind passives of so-called actional predicates, an asymmetry that has posed a major empirical challenge for theories of passive acquisition. This paper argues against the dominant view in the literature that treats the predicate-based asymmetry as…

Attitude verbs like "think" and "want" describe mental states (belief and desire) that lack reliable physical correlates that could help children learn their meanings. Nevertheless, children succeed in doing so. For this reason, attitude verbs have been a parade case for syntactic bootstrapping. We assess a recent syntactic…

The concept of bias is familiar to linguists primarily from the literature on questions. Following the work of Giannakidou and Mari (Truth and Veridicality in Grammar and Thought: Modality, Mood, and Propositional Attitudes, University of Chicago Press, Chicago, 2021), we assume "nonveridical equilibrium" (implying that p and ¬p as equal…

The present study investigated the second language processing of grammatical mood in Spanish. Eye-movement data from a group of advanced proficiency second language users revealed nativelike processing with irregular verb stimuli but not with regular verb stimuli. A comparison group of native speakers showed the expected effect with both types of…

The Mayan language Mam uses complex predicates to express events. Complex predicates map multiple semantic elements onto a single word, and consequently have a blend of lexical and phrasal features. The chameleon-like nature of complex predicates provides a window on children's ability to express phrasal combinations at the one-word stage of…

Usage-based theory has proposed that learning of linguistic constructions is facilitated by input that contains few high-frequency exemplars, in what is known as a skewed (or Zipfian) input distribution. Early empirical work provided support to this idea, but subsequent L2 research has provided mixed findings. However, previous approaches have not…

We investigated whether children's inhibitory control (IC) is associated with their ability to produce irregular past tense verb forms as well as learn from corrective feedback following overregularization errors. Forty-eight 3;6 to 4;5 year old children were tested on the irregular past tense and provided with adult corrective input via models of…

Literature on early language acquisition has observed that age of onset of acquisition (AoA) is relevant for certain grammatical phenomena. Simultaneous bilinguals receive regular and extensive exposure to two languages from birth (Müller, 2009), whereas sequential child learners get in extensive contact to L[subscript B] once the L[subscript A]…

We investigate the processing of "wh" questions in Niuean, a VSO ergative-absolutive Polynesian language. We use visual-world eye tracking to examine how preference for subject or object dependencies is affected (a) by case marking of the subject (ergative vs. absolutive) and object (absolutive vs. oblique), and (b) by the transitivity…

In Turkish, Relative Clause (RC) attachment ambiguity arises when two noun phrases (NPs) in a genitive construction follow the (RC). The present paper studies Turkish RC attachment preferences of Turkish native speakers in two experiments through off-line comprehension tasks. While in the first experiment the main verb immediately follows the NP…
