Purpose: The Arabic verb system features a nonlinear root and pattern derivational morphology. Previous studies suggest that young Arabic and Hebrew speakers' early verb use is based on semantic complexity rather than derivational morphological structure. The present study examines the role of morphological and semantic complexity in the emergence…

Aspect markers (AMs), temporal adverbs (TAs) and temporal nouns (TNs) are used by young Mandarin-speaking children to express time. However, the factors that affect the relative acquisition trajectories of these categories remains unclear. Accordingly, this study adopts Weist's time-concept model to examine the patterns of acquisition between and…

A cross-cultural investigation of lacunae contributes to successful intercultural communication, helping in achieving mutual understanding between cultures and solving communication problems between different nations. This study is aimed at identifying and classifying lexical lacunae in the kinship terminologies of the Russian and Kazakh…

The delayed acquisition of Spanish "ser" and "estar" is generally understood as rooted in the cognitive demands imposed by the integration of semantic-pragmatic and world-knowledge factors associated with their lexical meanings. Here we ask (1) what is the nature of this language world-knowledge integration? and (2) what is the…

This study investigates Mandarin-speaking children's knowledge of event semantics in interpreting spatial modifiers with "zai" 'at' after a posture verb or before a placement verb. The event-semantic principles investigated include subevent modification (Parsons, 1990) and aspect shift (Fong, 1997). We conducted an experimental study…

The ability to project oneself forward in time and imagine a future episode, known as episodic foresight (EpF), is an important aspect of future thinking. EpF tasks often involve children choosing an item for a future episode, yet the degree to which future projection is required to succeed -- versus memory or semantic associations -- has been…

While semantic and syntactic properties of verb meaning can impact the success of verb learning at a single age, developmental changes in how these factors influence acquisition are largely unexplored. We ask whether the impact of syntactic and semantic properties on verb vocabulary development varies with age and language ability for toddlers…

Language comprehension is remarkable in that we adapt easily to different forms of language use, from adapting to speakers' dialects, meanings of new slang words, and fictional worlds described in novels. While there is growing evidence comprehenders adapt their expectations for text during reading, the nature of these adaptation mechanisms…

Perception verbs and mental verbs have significant overlap in their syntax and semantics; both reference mental representations when taking embedded clauses, as in "I see that Maria was here" and "I think that Maria was here." Some have suggested that perception is more accessible for young children than mental states, raising…

This article reports on a study whose aim was to analyze the relation between the level of declarative purism and the preference for a particular loanword adaptation technique. Evidence from many languages shows that language purists accept foreign words more readily if they are in a native disguise; as a consequence, they choose adaptation…

This study investigated the impact of language modality and age of acquisition on semantic fluency in American Sign Language (ASL) and English. Experiment 1 compared semantic fluency performance (e.g., name as many animals as possible in 1 min) for deaf native and early ASL signers and hearing monolingual English speakers. The results showed…

Purpose: This study examines the effect of age on language use with an automated analysis of digitized speech obtained from semistructured, narrative speech samples. Method: We examined the Cookie Theft picture descriptions produced by 37 older and 76 young healthy participants. Using modern natural language processing and automatic speech…

Research has investigated how lexical-semantic and participant factors impact word learning in young children and adults. However, limited information pertaining to expressive vocabulary development exists for school-aged bilinguals--particularly those with developmental language disorder (DLD). Cross-linguistic differences in the semantic…

Acquiescence is often defined as the systematic selection of agreeable ("strongly agree") or affirmative ("yes") responses to survey items, regardless of item content or directionality. This definition implies that acquiescence is immune to item characteristics; however, the influence of item characteristics on acquiescence…

Researchers have identified sources of individual differences in writing across beginning and developing writers. The aim of the present study was to further clarify the sources of this variability by investigating the extent to which there are differences in genetic and environmental factors underlying the associations between lexical diversity,…
