Perspective-taking in deriving implicatures: The listener's perspective is important too

Area of Science:

• Psycholinguistics
• Cognitive Science
• Linguistics

Background:

• Theories of meaning suggest listeners infer implicit messages using conversational norms and contextual knowledge.
• Psycholinguistic studies indicate listeners derive quantity implicatures when speakers are knowledgeable, but less so otherwise.

Purpose of the Study:

• To investigate how listeners utilize their own unique knowledge (listener's perspective) when deriving implicatures.
• To explore the derivation of ad hoc quantity implicatures under varying speaker knowledge conditions, including listener's privileged knowledge.

Main Methods:

• Two experimental studies were conducted with neurotypical English-speaking adults.
• Participants' implicature derivation was assessed in situations manipulating speaker knowledge and listener's privileged information.

Main Results:

• Listeners' own perspectives significantly influenced their derivation of implicatures.
• The impact of the listener's perspective varied depending on the type of privileged knowledge available.

Conclusions:

• Listener's perspective is a crucial factor in pragmatic interpretation and implicature formation.
• Findings necessitate refinement of models explaining pragmatic interpretative strategies and knowledge-based inference.
