Using a set of carefully controlled scripted audio clips, Hilton surveyed 5,000 American English speakers to better understand what affects people’s perceptions of interruptions. She had participants listen to audio clips and then answer questions about whether the speakers seemed to be friendly and engaged, listening to one another, or trying to interrupt.
Hilton found that American English speakers have different conversational styles. She identified two distinct groups: high- and low-intensity speakers.
