Abstract: This study examined diglossia and its cognitive basis in Arabic. Repetition priming effects were compared within spoken Arabic (SA), as well as with the effects found when the primes were in either literary Arabic (LA) or Hebrew. In experiment 1, using lexical decisions for auditory presented words, a significant priming effect was found at lag 0 when the primes were in LA and in Hebrew. Furthermore, large repetition priming effects were found at relatively long lags (lag 8–12) within SA. This effect was absent when the repetition involved translation equivalents using either Hebrew or LA. The results showing that lexical decisions for words in SA were not influenced by previous presentations of translation equivalents in LA, in addition to the findings from a former study on semantic priming effects, suggest that the status of LA is similar to that of Hebrew and is consistent with the typical organization of L2 in a separate lexicon. Thus, learning LA appears to be, in some respects, more like learning a second language than like learning the formal register of one’s native language.
