Abstract:

This study probes the effects of allomorphy on access to Arabic roots and word patterns in two cross-modal priming experiments.This study probes the effects of allomorphy on access to Arabic roots and word patterns in two cross-modal priming experiments.Experiment 1 used strong roots which undergo no allomorphy, and weak roots which undergo allomorphy and surface with only two of their three consonants in some derivations. Word pairs sharing a root morpheme prime each other reliably not only when the root was strong (e.g., [muaarikun]/[aaraka] participant/participate), but also when it was weak (e.g., [ittifaaqun]/[waafaqa] agreement–agree, where the weak root {wfq} surfaces fully in the target but not the prime). This facilitation occurred even when the weak root surfaced with different semantic meanings across prime and target (e.g., [ ittiZaahun]/[waaZaha] destination/confront).Experiment 2 assessed the effects of allomorphy on word pattern processing, comparing word pairs where the word pattern is transparently realised in both prime and target (e.g., [ intaara]/[ i.tamala] spread/bear], with pairs which share the same underlying word pattern but where a weak root triggers an assimilation process in the prime (e.g., [ itta.ada]/[ ibtasama] unite/smile). This assimilation process does not disrupt the CV-structure of the word pattern, in contrast to a third condition where this is disrupted in both prime and target (e.g., [daara]/[qaala] turn around/say). Strong priming effects were observed in the first two conditions but notin the third. The bearing of these endings on models of lexical processing and representation is discussed.
