The role of executive function in perspective taking during online language comprehension

Area of Science:

• Psycholinguistics
• Cognitive Science
• Communication Studies

Background:

• Interlocutors build common ground, a set of shared beliefs, during conversation.
• The role of common ground in constraining initial language interpretation remains debated.
• Executive functions, particularly inhibition control, are proposed to explain occasional insensitivities to common ground.

Purpose of the Study:

• To investigate the role of executive functioning, specifically inhibition control, in common ground representation during language interpretation.
• To determine if individual differences in inhibition control affect the ability to inhibit perspective-inappropriate interpretations.
• To explore the influence of collaboratively established common ground on language processing.

Main Methods:

• An experiment was conducted to measure individual differences in inhibition control.
• Participants processed temporary referential ambiguities in speech.
• The study assessed the successful inhibition of perspective-inappropriate interpretations based on common ground status.

Main Results:

• Individual differences in inhibition control significantly predicted the degree to which participants inhibited perspective-inappropriate interpretations.
• Common ground status influenced interpretation, with collaboratively established information yielding greater sensitivity.
• Failures in inhibition control were linked to insensitivity to common-ground information.

Conclusions:

• Executive functioning, specifically inhibition control, plays a crucial role in managing common ground during online language processing.
• Occasional insensitivities to conversational perspective can be attributed to difficulties in inhibiting inappropriate interpretations.
• Common ground representations may primarily guide language processing when established collaboratively.
