Fig 1. Morphological processing theories of spoken word production.

Fig 1 is adapted from Beyersmann, Dutton, Amer, Schiller, and Biedermann [2]. Panel A represents the production of singular-dominant and plural-dominant plurals, based on a word production theory proposed by Levelt, Roelofs, and Meyer [4]. Panel B refers to a morphological processing theory of word production proposed by Biedermann, Beyersmann, Mason, & Nickels [1], and Panel C refers to a theory by Nickels, Biedermann, Fieder, and Schiller [9].
