Linking is the theory that captures the mapping of the semantic roles of lexical arguments to the syntactic functions of the phrases that realize them. At the sentence level, linking allows us to understand “who did what to whom” in an event. In Spanish, linking has been shown to interact with word order, verb class, and case marking. The current study aims to provide the first piece of experimental evidence about the interplay between word order and verb type in Spanish. We achieve this by adopting role and reference grammar and the extended argument dependency model. Two different types of clauses were examined in a self-paced reading task: clauses with object–experiencer psychological verbs and activity verbs. These types of verbs differ in the way that their syntactic and semantic structures are linked, and thus they provide interesting evidence on how information that belongs to the syntax–semantics interface might influence the predictive and integrative processes of sentence comprehension with alternative word orders. Results indicate that in Spanish, comprehension and processing speed is enhanced when the order of the constituents in the sentence mirrors their ranking on a semantic hierarchy that encodes a verb's lexical semantics. Moreover, results show that during online comprehension, predictive mechanisms based on argument hierarchization are used rapidly to inform the processing system. Our findings corroborate already existing cross-linguistic evidence on the issue and are briefly discussed in the light of other sentence-processing models.

We report an eye-tracking experiment that examined argument linking and the role of prominence in Spanish sentence comprehension by testing the interplay between word order and verb type. Previous evidence from a self-paced reading study (Gattei, Dickey, Wainselboim, & París, 2015). showed that comprehenders use morphosyntactic information to form predictions about the thematic structure of the upcoming verb. In this study we focussed on the time course of this process. Results showed an interaction between verb type and word order for late eye movement measures but not for early eye movement measures. Participants regressed more and for longer time when word order did not match the canonical order for each verb class. This interaction is observed from the verb region onwards, independently of word order. We interpret that these effects take place due to the misinterpretation of the prominence status of the preverbal argument, leading to differential reading strategies.
