When Developmental Language Disorder Meets Diglossia: A Cross-Sectional Investigation of Listening Comprehension Among Native Arabic-Speaking Preschoolers.

Diglossia in the Arabic language refers to the existence of two varieties of the same language: the Spoken Arabic (SA) and the Literary Arabic (LA). This study examined the development of listening comprehension (LC) among diglossic Arabic K1-K3. For this purpose, a large sample of typically developing (TD; N = 210) and developmental language disorder children (DLD; N = 118) were examined using SA and LA texts. The analysis of variance conducted on their performance in LC revealed significant effects of K-level, group (TD vs. DLD) and text affiliation (SA vs. LA): higher scores in TD and in SA. A significant interaction between text affiliation and K-level was observed among the TD but not the DLD group. This interaction indicated that the gap in LC between the SA and LA varieties decreased with age only among TD children. The theoretical and pedagogical implications of these results are discussed.

Children's Command of Four Inflectional Constructions in Arabic: Differences and Development With Age.

PURPOSE: This study examines whether differences in acquisition exist among the inflectional constructions of number, gender, possessive pronouns, and tense. Moreover, the study investigates whether these inflectional patterns develop with age. METHOD: The participants were 1,020 Arabic-speaking kindergartners from K2 and K3. Children were assessed in morphological tasks, which targeted four different morphological inflectional constructions both in real words and pseudowords: gender, number-plural, possessive pronouns, and tense. RESULTS: Findings reveal the differences between all inflectional constructions. In other words, children demonstrated higher performance in gender construction, followed by construction of numbers and possessive pronouns, while the lowest performance is shown among tense construction. In addition, the results indicate that all inflectional constructions develop with age, that is, there was higher performance in K3 than in K2 in all inflection constructions. CONCLUSIONS: This study contributes to our knowledge about early language development by showing that the acquisition of gender and number-plurals is faster and more advanced than the acquisition of possessive pronouns or tense. The implications of these results are discussed, especially the need to develop children's inflectional forms such as possessive pronouns and tense, which may eventually also impact narrative understanding and production.
