6.3 The Science of Conversation

Have you ever wondered what actually makes a conversation flow or fall apart? Why do some interactions feel effortless, while others feel awkward or draining?

In Episode 6.3 of The Science Basement, we sit down with Ville Harjunen from the Interaction Analysis Lab to explore the hidden science of human conversations. From subtle cues like nodding and backchanneling to brain activity and attention, Ville’s research uncovers the moment-to-moment dynamics that shape how we connect with others. We also explore how factors like personality, culture, and even video calls influence the way we communicate, listen, and respond.

Ville Harjunen is a researcher at the University of Helsinki whose work focuses on understanding social interaction through a combination of behavioral analysis, psychophysiology, and neuroscience.
