Every face-to-face conversation involves two people continuously monitoring, predicting, and reshaping each other’s behavior in real time, a process far more complex than simply trading words back and forth. That is the central finding of a major review published in Nature Reviews Psychology by researchers at the Max Planck Institute for Psycholinguistics and RWTH Aachen University, which reframes human dialogue as a form of coordinated joint action with significant implications for how people communicate in an increasingly screen-mediated world.
Conversation as a shared system
Authors Judith Holler and Anna K. Kuhlen argue that conversation is not simply one person speaking while another listens. It is a process in which both participants continuously monitor, predict, and shape each other’s behavior.
The review, published in February 2026, draws on empirical work to highlight the behavioral and cognitive complexities of communicating meaning in face-to-face conversation.
The authors describe conversation as a temporary partnership between minds, in which speakers anticipate responses before they arrive, and listeners prepare replies while still processing what they hear.
The review considers the implications of conceptualizing language as a situated joint action and summarizes work on three defining features of conversation: the integral role of visual bodily signals in composing and comprehending meaning and achieving mutual understanding; the role of addressee feedback in signaling understanding or difficulty understanding; and the cognitive demands that monitoring interlocutors for such signals places on participants.
The researchers reframe conversation as a form of multimodal joint action, closer to coordinated movement or ensemble performance than to a simple transfer of information. Holler writes: “Conversation is not a linear exchange of words. It is a jointly managed activity in which meaning emerges through coordination.”
Why video calls feel harder than they should
When that feedback loop is disrupted, for example, during lagging video calls or audio-only conversations, communication becomes more effortful and less fluid. The review highlights how deeply conversation depends on immediate, embodied feedback.
The finding arrives as Americans are spending more time than ever communicating through digital proxies. Research published last year found that the average person shares a live location with nearly four people as a substitute for the kind of spontaneous check-in that once happened face to face, a habit researchers warned risks crowding out the conversations that friendships actually run on.
Traditional psycholinguistic approaches to language have examined production and comprehension in isolation. However, these processes are tightly intertwined and embedded in social interactions.
The Max Planck review synthesizes findings across neuroscience, linguistics, and cognitive psychology to show that the two processes are inseparable in live human interaction.
Small talk is better than people expect
A separate study published in the Journal of Personality and Social Psychology in April 2026 adds a practical dimension to the picture. The small talk people try to avoid because they think it will be boring may actually be more enjoyable than they think, and good for them as well, according to research published by the American Psychological Association.
The paper was authored by Elizabeth Trinh of the University of Michigan’s Ross School of Business, Nicole Thio of Cornell University’s Industrial and Labor Relations School, and Nadav Klein of INSEAD, and was published online April 13, 2026.
Together, the two studies converge on a shared conclusion: people systematically undervalue the depth and quality of in-person talk, whether by avoiding casual exchanges or by substituting real dialogue with digital shortcuts.
That gap in connection carries measurable social costs. Only 22% of Americans report having an intergenerational close friend, an AARP study found, a statistic researchers in that field have linked in part to declining habits of spontaneous, unstructured conversation across age groups.
What it means for everyday life
Researchers at the University of Vermont have uncovered a new insight about how language works, one that overturns a cornerstone assumption in psychology, linguistics, and artificial intelligence that has stood for more than 70 years. Their study, published May 6 in Science Advances, introduces “ousiometrics,” the quantitative study of essential meaning, and reveals that language is fundamentally organized not around emotion alone, but around a deeper structure shaped by power, danger, and order. At the heart of the discovery is a striking finding: human language is systematically biased toward safety.
That safety orientation may help explain why people gravitate toward comfortable, low-stakes digital exchanges rather than the unpredictable back-and-forth of live talk.
The Max Planck review does not prescribe a fix, but its diagnosis is precise: the richness of human conversation is not incidental to its content but built into the real-time physical feedback that participants exchange moment by moment.
Removing those cues, through a screen, a time lag, or a text thread, does not simply change the medium. According to Holler and Kuhlen, it changes the conversation itself.
