Syntactic Errors in Older Adults with Depression.

Background and Objectives: This study investigated the differences in syntactic errors in older individuals with and without major depressive disorder and cognitive function disparities between groups. We also explored the correlation between syntax scores and depression severity. Materials and Methods: Forty-four participants, assessed for dementia with the Mini-Cog, completed the 15-item Geriatric Depression Scale (TGDS-15) and specific language tests. Following a single-anonymized procedure, clinical psychologists rated the tests and syntax scores. Results: The results showed that the depressive disorders group had lower syntax scores than the non-depressed group, primarily on specific subtests. Additionally, cognitive test scores were generally lower among the depressed group. A significant relationship between depression severity and syntax scores was observed (r = -0.426, 95% CI = -0.639, -0.143). Conclusions: In conclusion, major depressive disorder is associated with reduced syntactic abilities, particularly in specific tests. However, the relatively modest sample size limited the sensitivity of this association. This study also considered the potential influence of cultural factors. Unique linguistic characteristics in the study's context were also addressed and considered as potential contributors to the observed findings.

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

In typological literature, there has been disagreement as to whether there should be distinction between relative clauses (RCs) and nominal sentential complements (NSCs) in pro-drop languages such as Japanese, Chinese, Korean, Khmer and Thai. 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.
