How does dissociation between written and oral forms affect reading: evidence from auxiliary verbs in Arabic

Abstract

In Arabic, auxiliary verbs are necessary in the written language, but absent from the oral language. This is contrary to languages such as English and French in which auxiliary verbs are mandatory in both written and oral languages. This fact was exploited to examine if dissociation between written and oral forms affects reading measures like letter detection task and therefore to validate the phenomenon of the missing‐letter effect (MLE) and to replicate previous studies. In addition, the study examined whether auxiliary verbs in Arabic are considered as functional elements that constitute part of the structural frame. Sixty native Arabic speakers read a passage while looking for a target letter that was embedded in a preposition, an auxiliary verb or a content word. Results showed the typical MLE with more omissions for the preposition than for the content words. However, the results with the auxiliary verb are less clear. The functional and the syntactic roles of auxiliary verbs in Arabic are discussed.
