"This Isn't a Promise, It's a Threat"

Area of Science:

• Psycholinguistics
• Cognitive Science
• Linguistics

Background:

• Understanding how humans process language, particularly speech acts like promises and threats, is crucial for cognitive science.
• Previous research has explored the semantic and pragmatic nuances of speech acts, but the processing of anaphoric references to implied promises and threats requires further investigation.

Purpose of the Study:

• To investigate the cognitive processing of anaphoric references to implied promises and threats.
• To examine the role of semantic scope differences between 'threat' and 'promise' in language comprehension.
• To determine the temporal dynamics of processing mismatched speech act meanings.

Main Methods:

• Eye-tracking was used to record participants' reading times as they processed vignettes.
• Participants read sentences containing implied promises and threats, with specific target words ('threat', 'promise') analyzed.
• A two-part processing measure was employed, assessing immediate and later reading time penalties.

Main Results:

• A reading time penalty was observed when 'threat' referred to an implied promise, but not vice versa initially.
• Later processing revealed reading time penalties for both 'threat' referring to a promise and 'promise' referring to a threat.
• These findings indicate an initial asymmetry in processing based on semantic scope, followed by sensitivity to meaning mismatches.

Conclusions:

• The initial processing of anaphoric references to threats and promises is influenced by the semantic scope asymmetry where threats can be a type of promise.
• This asymmetry effect is transient, with readers ultimately detecting and penalizing meaning mismatches regardless of the speech act performed.
• Language comprehension involves dynamic adjustments, moving from initial semantic biases to a more robust sensitivity to overall meaning coherence.
