Research paper thumbnail of The Processing of Relative Clause Attachment as a Tool for Resolving a Problem in Typology of Relative Clauses: Preliminary Evidence from Thai Data

Journal of Psycholinguistic Research, Oct 20, 2017

In pro-drop languages, nouns can be dropped when its reference can be retrieved from context. Therefore, what has been defined as a gap in RCs (i.e., the controversial element hereafter) and has often been used for differentiating RCs from NSCs might actually be a zero pronoun, making syntactic structures of RC and NSCs indistinguishable. This article reviews the study of the processing of RC attachment in Thai and discusses how its results provide preliminary evidence supporting that RCs and NSCs in Thai are syntactically different constructions and the controversial element in RCs is not a zero pronoun. The article suggests a new promising tool for investigating an unresolved typological problem. Keywords Typology • Relative clauses • Gap • Zero pronoun • Relative clause attachment Traditional Analyses: Syntactic Distinction Between RCs and NSCs Strings of words that function to give information about the head noun are often categorized either as relative clauses (RCs) as in (1) or nominal sentential complements (NSCs) as in (2). In this article, what will be referred to as traditional analyses is analyses that distinguish RCs from NSCs. For the traditional analyses, the presence of a gap (Comrie 1998) and the well-formedness of the clause (Kullavanijaya 2010, p. 60) are often adopted syntactic criteria to differentiate RCs from NSCs. RCs are claimed to contain a gap, making the clause incomplete as one of the arguments is extracted. The structure of NSCs on the other hand is the same as that of well-formed sentences. In English and European languages, the syntactic distinction between B Teeranoot Siriwittayakorn

Instances of adjacency violation pose a challenge to researchers but also an opportunity to better understand how people process sentences and to improve parsing algorithms by, for example, suggesting new features that can be used in machine learning. We report corpus counts and reading-time data for Thai to investigate an adjacency violation that has been reported in other languages for ambiguous relative clauses that can be attached to either of two nouns, namely, the local noun (which is adjacent to the relative clause) or the non-local noun (which is farther from the relative clause). The results indicate that, unlike English, Thai violates adjacency by favoring non-local attachment even though the two languages share many grammatical features that have been linked to a local-attachment preference (e.g., rigid SVO word order). We reinterpret previous proposals to suggest that a language favors the non-local noun if it passes at least one of two tests. (1) Modifiers can intervene between noun and relative clause. (2) Adverbs can intervene between transitive verb and direct object.

Two issues are addressed. Firstly, we investigate whether experience with a construction with identical surface word order, namely nominal sentential complements, can affect the processing of relative clauses. Secondly, we investigate whether previously-reported effects of experience in sentence processing reflect general learning that can change participants' preferences or whether it only reflects strategic learning that helps participants perform better in a specific situation.We report a corpus count showing that local attachment (e.g., attaching the relative clause to "the runner") is more frequent than non-local attachment (e.g., attaching the relative clause to "the co...

However, little is known about how unexpected situations affect information processing. This study investigated the processing of possibility hedges. Specifically, it tested whether participants ignored possibility hedges when processing medical diagnoses and medical advice that contradicted their expectation. The results suggested that possibility hedges used in sentences did not affect the degree of participants’ surprise when reading unexpected text continuations. However, it was found that although participants paid attention to possibility hedges when asked to rate credibility of the texts, they paid attention to the hedges to a varying degree depending on whether situations mentioned in the text turned out to be better or worse than expected. The study added to the body of literature in information processing that unexpec...

Participants were slower to read sentences containing agreement violations, in a manner similar to what has been reported for native English speakers. The results add to a growing literature according to which learners can acquire knowledge of number agreement even if their native language lacks it. This suggests that learners are not constrained by the features available in their native languages, and are able to acquire new features and put this knowledge to use when reading sentences for content.

Studies across various languages have investigated ambiguous relative clauses that can be attached to either of two nouns to determine the types of languages in which locality is violated. We report a corpus count and a questionnaire in Thai indicating that intra-sentential contexts can obscure locality. Two reading experiments controlling for context are also reported in support of locality in Thai. The finding that context distorted locality raises the possibility that previous reports of locality violations in various languages may be reduced to contextual effects.
