- Abstract
Objective: Arguments that contribute to verb meaning are labeled as thematic roles. For instance, sentences containing the verbs düşmek/koşmak have no object arguments (intransitive), whereas sentences containing the verbs düşürmek/koşturmak are determined to have objects (transitive). Intransitive verbs differ in what kind of roles their subjects take, which is postulated by the Unaccusative Hyphothesis: The subject of the intransitive verb düşmek takes a theme role, while the subject of the intransitive verb koşmak takes an agent role. Previous studies on agrammatic aphasia were based on the assumption that verbs with a greater number of arguments are more difficult to process, as predicted by the influential Argument Structure Complexity Hypothesis (ASPH). There are many cases in Turkish where transitive verbs are derived from intransitive verbs with causative morphemes. Thus, Turkish provides a suitable environment to test the transitivization effect in agrammatic aphasia. The aim of this study is 1) to reveal the effect of transitivization on the online sentence processing in Turkish-speaking agrammatic aphasia and, 2) whether there is a processing difference between the intransitive verb types. Methods: In this study, participants [aphasia (n=18) & control (n=18)] listened to sentences (n=160) including these four types of verbs. While listening, two pictures in which one of two pictures was strongly related to the argument of the verb were shown on the screen and eye movements were monitored. Results: Linear mixed effect model revealed that the main effects of group and verb type were significant for accuracy and reaction time. The results of GAMM analysis showed that the group effect in transitive verbs was significant, but not in intransitive verbs. Conclusion: These findings confirm the ASPH, but reveal that there is no hierarchy of difficulty for agrammatic aphasia among the verb types that differ according to the Unaccusative Hyphothesis.
