Abstract
Phonological processes such as place assimilation, in which coronal sounds partially adopt the place of a subsequent noncoronal (e.g., green boat becomes green/m boat), may create ambiguity during speech comprehension, but may also paradoxically facilitate word recognition. Gow (2001) demonstrated that partial assimilation facilitates perception of postassimilation context. Two eye‐tracking experiments investigated whether this progressive effect is influenced by lexical processes. Assimilated and nonassimilated adjectives (e.g., green) were spliced onto coronal or noncoronal nouns (e.g., boat or dog) to create phonologically plausible and implausible assimilation. In experiment 1, assimilation resulted in nonwords; in experiment 2, words assimilated into other words, cuing lexical competition (e.g., cat box became cat/p box). Subjects viewed a screen showing 4 pictures: a coronal noun, 1 noncoronal, and 2 fillers. Eye movements were monitored as subjects heard instructions to select a picture with a mouse. In both experiments subjects were reliably faster to look at the noncoronal target following the assimilated adjective than the nonassimilated one. This progressive effect occurred approximately 100 ms later when assimilation created competitors (experiment 2). These results support an interactive view of word recognition in which lexical processing interacts in real time with phonological and perceptual grouping and integration processes.
