How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Chapter
Interpersonal synchrony is associated with better interpersonal affiliation. No matter how well-affiliated people are, interruptions or transitions in synchrony rebound to occur. One might intuitively expect that transitions in synchrony negatively affect affiliation or liking. Empirical evidence, however, suggests that time periods with interrupti...
Presentation
Social interaction often occurs through emerging patterns. Such patterns develop over time due to mental processes that in turn are adaptive. In this speech, an agent-based adaptive network modeling perspective is used for computational analysis and simulation of the different forms of adaptivity that play a role. It is shown how mechanisms based o...
Presentation
When humans interact, multiple types of adaptivity occur, concerning their behaviour toward each other. For example, these types of behavioural adaptivity include short-term effects such as affiliation but also long-term effects such as bonding. Moreover, some forms of behavioural adaptivity apply to specific persons, whereas other forms apply in a...

This joint Keynote Speech focuses on agent modeling for multimodal interactions of both humans and artificial agents. For a video, see https://www.youtube.com/watch?v=aVhm7a1PXJg. Human interaction often happens through different modalities such as movements, facial expressions, and verbal utterances. These multimodal human interactions often becom...

This behavioural adaptivity may concern short-term effects such as affiliation but also long-term effects such as bonding. Interaction can involve different modalities such as movement, affect and ver...

Full-text available
Although there is much literature on multimodal interaction, multimodal synchrony analysis, and related behavioural adaptivity, mathematical formalisation and computational simulation of it is a nontrivial topic. Moreover, the subjective, agent-oriented perspective on synchrony analysis has not yet received much attention in the literature. This bo...
Chapter
Interpersonal synchrony usually means that people mutually adapt their behavior to each other over time. Such behavioral adaptivity is assumed to be driven by some form of subjective internal synchrony detection. In contrast to objective synchrony detection by an external (third-party) observer, subjective synchrony detection relies solely on infor...

Chapter
For a video presentation, see https://www.youtube.com/watch?v=PRUzrkf1mW4. When people interact, their behaviour tends to become synchronised, a mutual coordination process that fosters short-term adaptations, like increased affiliation, and long-term adaptations, like increased bonding. This paper addresses for the first time how such short-term a...
Conference Paper
For a video presentation, see https://www.youtube.com/watch?v=SRfB0Pphi34. Interpersonal synchrony usually induces behavioural adaptivity concerning the interaction between people. Such behavioural adaptivity is assumed to be driven by some form of subjective internal synchrony detection. In contrast to objective synchrony detection by an external...

Conference Paper
It has been found that interpersonal synchronization leads to more closeness, mutual coordination, alliance, or affiliation between the synchronized persons. Such literature reveals a pathway from interpersonal interaction to interpersonal synchronisation to interpersonal affiliation. If persons act on temporal patterns of synchrony, this suggests...
Chapter
People spontaneously synchronize their mental states and behavioral actions when they interact. This paper models general mechanisms that can lead to the emergence of interpersonal synchrony by multiple agents with internal cognitive and affective states. In our simulations, one agent was exposed to a repeated stimulus and the other agent started t...
Article
Joint decision-making can be seen as the synchronization of actions and emotions, usually via nonverbal interaction between people while they show empathy. The aim of the current paper was (1) to develop an adaptive computational model for the type of synchrony that can occur in joint decision-making for two persons modeled as agents, and (2) to vi...
Article
Full-text available
Recent years have seen a dramatic increase in studies measuring brain activity, physiological responses, and/or movement data from multiple individuals during social interaction. For example, so-called “hyperscanning” research has demonstrated that brain activity may become synchronized across people as a function of a range of factors. Such findin...

People spontaneously synchronize their activities when they interact. This paper models the emergence of interpersonal synchrony by multiple agents with internal cognitive and affective states. In our simulations, one agent was exposed to a repeated stimulus and the other agent started to synchronize consecutively its movements, affects, conscious...

Project
For humans, it is not always easy to gain insight into their own behaviour and its underlying mental, neural, and bodily processes. If, for example, you wish to learn of a specific physical exercise, it is often very helpful if someone else demonstrates the exercise well and perhaps even more if this someone else can also show what you are still doing wrong with it. In a comparable manner, therapies or coaching sometimes use role-play to help people to understand their own functioning. This project addresses how this principle can be extended in a more flexible manner by using virtual role-play, where artificial humans using avatars perform the role-play in a virtual environment. This requires artificial humans that can reflect well specific types of natural humans and their underlying mental and neural processes, including the imperfections in them. To achieve this, this project applies AI-modeling techniques incorporating mechanisms described for natural humans in the literature on psychology and neuroscience.
