Syntactic and semantic information in Tagalog reflexive processing
This is work in progress and is in collaboration with
Brian Dillon.
In English, abstract syntactic principles regulate coreference in reflexives (Chomsky, 1981).
There is some debate, however, on the status of these constraints in Austronesian languages.
For example, some scholars argue that these languages have semantically-grounded constraints on reflexive interpretation,
such as a thematic hierarchy (e.g. Andrews (1985) for Tagalog;
Bell (1976) for Cebuano;
and Van Valin (1999) for Toba Batak, another related language spoken in Indonesia).
On the other hand, some have argued that much like English, these languages have structurally-grounded constraints (Rackowski, 2002; Richards, 2013).
The goal of this project is to address this debate by combining fieldwork and large-scale experimentation.
To investigate the role of grammatical constraints on resolving a reflexive’s real-time interpretation,
researchers have largely used variants of Sturt’s mismatch paradigm (2003).
For example, researchers have examined the extent to which comprehenders momentarily consider DPs not licensed by Principle A (henceforth, distractor) as they process the reflexive.
In this paradigm, researchers systematically manipulate the features of the distractor,
and measure whether comprehenders are sensitive to the matching features between the distractor and the actual antecedent. Consider: The new executives who oversaw the middle manager(s) doubted themselves...
To the extent that themselves is processed differently when the distractor is singular and when it is plural indexes attention to the features of the distractor.
This indicates activation during the course of resolving the reflexive’s reference.
Any influence exerted by the distractor is referred to as interference effects.
I am investigating the extent to which Tagalog comprehenders attend to syntactic factors (e.g., c-command and locality) and to semantic factors (e.g., thematic relations) during the real-time comprehension of reflexives.
To this end, I have conducted a large-scale offline antecedent selection experiment to investigate reflexive licensing.
Consistent with Principle A, participants overwhelmingly chose as antecedents DPs that were in the same clause and that c-commanded the reflexive.
DPs not licensed by Principle A—either because they did not c-command or they were not in the same clause as the reflexive, or both—had very little impact on participants’ ultimate interpretation.
This part of the project has been presented at the 15th Philippine Linguistic Congress and at the 30th Annual Meeting of the Austronesian Formal Linguistics Association.
I have also conducted a self-paced reading experiment using a number-mismatch paradigm to see whether distractors were momentarily considered as antecedents.
Participants’ responses to comprehension questions replicated the offline interpretations.
However, their reading times suggested that they were momentarily considering the distractor in a way that is not predicted by the models of retrieval espoused by Lewis & Vasishth (2005) or by Dillon et al. (2013). A more articulated version of this research is available here.
In another self-paced reading experiment, I have partially replicated these findings. Responses to comprehension questions were again replicated.
Their reading times, however, provided no evidence that they were attending to the distractor.
While I had collected data from 104 participants, only data from 58 were left after adopting the same exclusion criteria as the earlier study.
The results were trending in the same direction, suggesting that this failure to replicate could be due to low power.
These inconsistencies echo recent research by Jäger et al. (2017) that suggested that effect sizes of interference effects in reading measures are small and easily require 100+ participants to yield sufficient power to detect.
The unclear empirical picture to date suggests that an alternative experimental methodology would be helpful to investigate interference effects.
For this reason, I adopted a fairly underutilized paradigm to measure real-time interference: the visual world paradigm.
An additional benefit of this paradigm is that the linking hypothesis between models of retrieval (Lewis & Vasishth, 2005) and the experimental measures is fairly straightforward:
visual attention is typically taken to be a probabilistic function of attention (Allopena, Magnuson, & Tanenhaus, 1998).
Thus, in VWP, we can directly track the degree to which different DPs are activated and considered during the processing of a reflexive pronoun.
This summer (August to September 2023), I started running a visual word experiment to investigate interference effects, where the distractor is inside a relative clause that is modifying the antecedent.
I have collected data from 80 participants, out of 120, and will be finishing data collection this December. Next year (around July to August 2024), I will be running another visual world experiment to test whether the thematic role of the distractor modulates the degree of interference.
If comprehenders resolve reflexive interpretation by making reference to thematic prominence à la Andrews (1985), then we expect to see more pronounced interference effects from distractors that are more prominent on the hierarchy (agents) than those that are less prominent (patient).
