Identifying a temporal threshold of tolerance for silent gaps after requests

Area of Science:

• Psychology
• Linguistics
• Social Interaction

Background:

• Understanding conversational dynamics is crucial for effective communication.
• The impact of silence in dialogue on social perceptions is not fully understood.
• Inter-turn silence can influence how speakers are perceived.

Purpose of the Study:

• To determine if a specific duration of silence between speakers' turns triggers negative social judgments.
• To investigate the threshold at which inter-turn silence affects perceptions of willingness.

Main Methods:

• Constructed dialogues with identical, affirmative responses to requests.
• Manipulated the lag time (inter-turn silence) between 200 and 1200 milliseconds in 100 ms intervals.
• Collected willingness ratings from 380 study participants in a between-groups design.

Main Results:

• A noticeable decrease in willingness ratings occurred at 600 ms of silence.
• A statistically significant difference in willingness ratings was observed between 700 ms and 800 ms.
• Response latency, not semantics, influenced participant perceptions.

Conclusions:

• A silence threshold of approximately 600-700 ms exists for negative social attributions.
• Inter-turn silence duration is a key factor in perceived willingness.
• Findings have implications for understanding social cues in human-computer and human-human interaction.
