Why bother? What our eyes tell about psych verb (non) causative constructions

We present an eyetracking study that investigates how linking is achieved during real-time comprehension of Spanish sentences with causative psych verbs and alternative case marking. This group of verbs lead to verbs’ argument structures that require direct or inverse syntax-to-semantics linking according to the type of case marking assigned to their object. The study aimed at disentangling whether processing inverse linking was more costly than direct linking, and exploring how incremental argument interpretation takes place when lexemes that accept several case markings are used. Results showed that during incremental comprehension, inverse linking is more difficult than direct linking, irrespective of word order. As for argument interpretation, the current study partially replicated the results of previous studies conducted in this language using different verb types. Findings are discussed under the light of different psycholinguistic models addressing case marking processing and incremental linking.
