This study aimed to adapt and validate the Word Complexity Measure (WCM) for Persian-speaking toddlers. The WCM is a tool for assessing phonological complexity, originally proposed by Stoel-Gammon. The study was conducted in two phases: (1) adapting the WCM parameters to the Persian language and (2) conducting a validation study with 60…

The association between pre-reading skills and phonological production skills has been shown at school age, but less is known about how these skills interact at an earlier age when they are just developing. The focus was to investigate whether a connection between pre-reading skills (letter naming, rapid automatised naming; RAN) and phonological…

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…

In individuals with Down syndrome (DS) deficits in verbal short-term memory (VSTM) and deficits in sentence comprehension co-occur, suggesting that deficits in VSTM might be causal for the deficits in sentence comprehension. The present study aims to explore the presumed relationship between VSTM and sentence comprehension in individuals with DS…

Efficient visual exploration in infancy is essential for cognitive and language development. It allows infants to participate in social interactions by attending to faces and learning about objects of interest. Visual scanning of scenes depends on a number of factors, and early differences in efficiency are likely contributing to differences in…

Heritage language (HL) speakers seem to diverge from monolingual speakers in the acquisition of syntax-discourse interface phenomena. However, most of the studies reporting this finding do not make any distinction between different types of syntax-discourse interface structures. Therefore, it is an open question whether these structures are…

The purpose of this study was to examine early fast mapping abilities in late talkers (LT) and typically developing (TD) Spanish-speaking children by considering the effect of different variables on fast mapping (age, vocabulary level, grammatical category and number morphology). Thirty-eight Spanish-speaking children were assessed at three times…

Mutual exclusivity (ME) refers to the assumption that there are one-to-one relations between linguistic forms and their meanings. It is used as a word-learning strategy whereby children tend to map novel labels to unfamiliar rather than familiar referents. Previous research has indicated a relation between ME and vocabulary development, which…

Working memory (WM) limitations are frequently reported for children with specific learning disorder (SLD). However, WM capacity influences more than literacy and numeracy, as research highlights the contribution of WM to language development, in particular syntax. In this article, the authors study the effect of syntactic intervention, i.e.…

Morphophonological processing involves the phonological analysis of morphemes. Item-specific phonological characteristics have been shown to influence morphophonological skills in children. This study investigates the relative contributions of broad phonological skills and vocabulary to production and judgement accuracies of the Dutch past tense…

This study aimed to investigate specific associations between structural and acoustic characteristics of infant-directed (ID) speech and word recognition. Thirty Italian-acquiring children and their mothers were tested when the children were 1;3. Children's word recognition was measured with the looking-while-listening task. Maternal ID speech was…

Weak performance in short-term memory (STM) in children with cochlear implants (CI) may have an impact on vocabulary development. Vocabulary, phonological STM (non-word repetition), phonological/verbal STM (digit span) and rapid naming measures were administered to 15 Greek-speaking children with CI (ages 4;6-8;6) and to chronological age (CA) and…

Across languages, children do not comprehend 3SG/3PL subject-verb agreement before age five, despite early mastery in spontaneous speech. This study investigates subject-verb agreement in a language hitherto not studied in this respect, namely Dutch. The authors examine if (1) Dutch two- and three-year-olds comprehend subject-verb agreement and…

This study investigated children's narrative evaluations about jealousy in relation to performance on a higher-order perspective-taking task and assessments of receptive vocabulary and nonverbal intelligence. Eighty children (5;0-11;11) narrated a wordless picture book about a jealous frog, answered probe questions about the plot, and generated a…

Forty native Spanish-speaking children (age 8;0-10;3), 20 with Specific Language Impairment (SLI) and 20 with Typical Language Development (TLD), received a battery of psycholinguistic tests, IQ, hearing screenings, and the Spanish Non-word Repetition Task (NRT). The children's repetition of 20 non-words was scored. The percentage of correct…
