The impact of diglossia on phonological representation in Arabic speaking children

The study tested the impact of the phonological distance between Spoken Arabic (SpA) and Standard Arabic (StA) on quality of phonological representations among kindergarten, first-, second-, and sixth-grade Arabic-speaking children (N = 120). A pronunciation accuracy judgment task targeted three types of StA words that varied in extent of phonological distance from their form in SpA: (a) IDENTICAL WORDS, with an identical lexical–phonological form in StA and SpA; (b) COGNATE WORDS, with partially overlapping phonological forms; items in this category varied in degree of phonological distance too; and (c) UNIQUE WORDS with entirely different lexical–phonological forms. Multilevel Regression analysis showed that phonological distance had a significant impact on quality of phonological representations across all grades. Growth in quality of phonological representations was mainly noted between the three younger groups and the sixth-graders. Implications for the impact of phonological distance on phonological representations and on language and literacy development are discussed.
