Theories of linguistic knowledge sometimes invoke prominence scales rooted in features like animacy (animate > inanimate; where “>” means “outranks in prominence”) and grammatical role (subject > indirect object > direct object) to explain a wide range of phenomena. Such prominence scales have been argued to be relevant to psycholinguistic theories, but open questions remain about the exact mechanism(s) which directly reference these scales in online processing. The present study aims to test the role prominence plays in incremental sentence comprehension by examining Georgian, a language whose morphosyntax makes it an especially good testing ground. In two self-paced reading experiments, patterns of incremental difficulty strongly suggest that the parser navigates incremental ambiguities that stem from case morphology by harmonically aligning scales for animacy and grammatical role.
