The Bear or the Lion - Who Did It? Adaptive Integration of Verbs and Adjectives in Pronoun Resolution
SymposiumTalk-05
Presented by: Verena C. Seibold
Language comprehension relies on integrating lexical-semantic expectations and discourse-level cues, including contextual and causal information. Implicit Verb Causality (IVC) assigns default causal roles to discourse protagonists, fostering expectations about event interpretation. However, these verb-based expectations can be modulated by additional cues, such as adjective semantics. For example, in Winograd-style scenarios (“The trophy doesn’t fit in the brown suitcase because it is too small/large”), the adjective determines which referent maintains a coherent causal interpretation. This study examines how adjective semantics interacts with IVC to establish coherent causal relations.
In two experiments, participants read short event descriptions followed by explanations containing an ambiguous pronoun and an evaluative adjective (e.g., “The bear annoyed the lion because it was aggressive.”). We manipulated whether the adjective-induced causality was congruent or incongruent with the IVC bias of the verb. Participants then judged the coherence of a target sentence by explicitly resolving the pronoun (e.g., “The lion was aggressive.”).
Coherence judgments reflected an interaction between verb- and adjective-based biases: coherence was highest when both aligned and decreased when they conflicted. Adjective-driven expectations were weighted more strongly than verb-based biases, which still influenced interpretation. This differential weighting shows that readers combine multiple sources of information in a flexible, cue-weighted manner, demonstrating adaptive integration in pronoun resolution to maintain coherence under ambiguity.
