The Effect of Prior Context on the Resolution of Structural Ambiguity with Variants of the Indirect/Oblique Relative Clauses in Brazilian Portuguese
Keywords:
Relative clause processing, Prior context, Temporary ambiguity, Self-monitored reading, MemoryAbstract
This study focuses on the processing of temporary ambiguities, introducing a novel phenomenon—indirect/oblique relative clauses in Brazilian Portuguese (BP). The aim was to verify whether prior contexts with low or high plausibility could favor the reading of “que” (that/which), in constructions such as “Pedro disse ao professor que Alice entregou o relatório que precisa...” (Pedro said to the teacher that Alice delivered the report that she needed...), as a relative pronoun, instead of a subordinating conjunction, in contrast to standard relative clauses (“(...) ao professor para quem Alice entregou (...)”), without ambiguity. Forty-seven participants took a self-monitored reading test, with short stories followed by a comprehension question. The dependent variable was the reading time (RT) of the sentence segments. The type of relative clause (standard or cutting), and the type of prior context (low or high plausibility for a relative clause) were the independent variables (Maia et al., 2003; Soares, 2014). An adapted verbal working memory test was also administered (Kim; Oines; Miyake, 2017). Our results indicate that, when faced with this type of structure, the embedded clause is preferentially read as a complement clause. The context has only a marginal effect on the critical segment, while the type of relative clause significantly impacts processing cost, which is maintained in the subsequent segment. The standard relative clause shows quick recovery, particularly in high context, although the interaction is only marginal. The memory score only showed a positive correlation with performance on the comprehension task in the low plausibility context. It is inferred that, in a challenging scenario, i.e., low plausibility and structural ambiguity, individuals with greater memory capacity show better processing performance with complex syntactic structures.
