Competition Between Primary and Nonprimary Relations During Sentence Parsing

 Saveria Colonna and Joel Pynte
  
 

Abstract:
The aim of this poster is to discuss Frazier and Clifton's distinction between primary and non-primary relationships, and more precisely their claim that "an underspecified analysis is assigned only to nonprimary relations." An eye tracking experiment, conducted in French, is reported, whose results suggest that in case of conflict between a primary and a non primary relation, the decision concerning the primary relation can be delayed. The sentences were of the following type (simplified English examples) :

(1) Tired (masculine) of calling the man he left the room.

(2) Tired (feminine) of calling the man she left the room.

The first NP, "the man," can be interpreted either as the direct object of "calling" or the subject of "left" (competition between two primary relationships). However, "the man" is also the potential subject of the adjunct predicate "tired" (depending on gender agreement). That is, if "tired" and "the man" have the same gender (first example), the reader will have a tendency to consider that "the man" is the one who is "tired." As a consequence "the man" also becomes the likely subject of "left." By contrast, in the case of gender disagreement, "the man" cannot be the subject of the adjunct predicate and thus keeps being a potential object for the preceding verb, in accordance with the usually preferred interpretation for a noun phrase in such a position.

The analyis of regressions suggested that gender agreement was checked at the moment when the ambiguous NP was being processed, and that a decision concerning the adjunct predication was made at that moment. Moreover, the analysis of first fixation duration at the diambiguating point suggested that the ambiguous NP was indeed given the status of potential subject of the following verb in the gender agreement condition. The decision concerning the non-primary relationship did not trigger a full commitement in favor of the subject interpretation however, as indicated the data recorded on the subject-disambiguated sentences, that the participants were also presented with. Two types of subject-disambiguated sentences were compared:

(3) Tired(masc) of calling(optionally trans) the man left the room.

(4) Tired(masc) of chatting(intransitive) the man left the room.

First fixation durations and first-pass gazes at the disambiguating point were shorter in the intransitive condition (4), suggesting that the status of the ambiguous NP was left undecided until the disambiguating region was reached in the optionally transitive condition.
