Comparative joint action lab

Welcome to the lab web page! Led by Raphaela Heesen, this group aims to study social behaviour, communication, and emotions in primates, with a focus on joint action.

Dr. Raphaela Heesen

Welcome to Our Lab!

 

I am an evolutionary and behavioral biologist just launching my own research group this year at the University of Konstanz (Germany) and the University of Zürich (Switzerland). My research explores what sets humans apart from other primates in communication, emotions, and interaction skills, while also examining shared mechanisms of collaboration across species. Observing natural behaviors like social grooming and play, we complement our findings with experimental approaches, using cutting-edge methods such as thermal imaging, eye-tracking, automated posture tracking, and non-invasive cortisol analyses.

 

​My goal is to identify emotional and communicative signals that facilitate joint action coordination: How do different primate species resolve communication breakdowns? What emotion expressions or behavioral processes support cooperation? Does the sharing of emotional states strengthen bonds and the sense of commitment? How do humans and chimpanzees develop advanced collaboration skills, and what are their evolutionary foundations?

 

To answer these questions, my group and I study joint action across cultures in adults and children (3-10 years) and compare findings with nonhuman primates, including bonobos, chimpanzees, and soon, Callitrichid monkeys. These comparisons help us trace the evolutionary, developmental, and cultural origins of cooperative and communicative skills and other interactional processes like synchrony and emotion contagion.

 

I am excited to promote “comparative joint action research” as a new research line in comparative psychology and behavioral biology. Early findings already provide promising insights that there is much to discover about how nonhuman primates navigate social interaction and commitment through communication. For instance, my collaborative work with colleagues from the University of Neuchâtel revealed that bonobos and chimpanzees, like human children, resume interrupted joint actions with peers and communicate depending on social relationships with their partners (Heesen et al., 2020, Science Advances; Heesen et al., 2021, Royal Society Open Science). We also recently showed that this capacity seems to develop with age, opening up exciting future avenues for developmental psychology research in apes (Heesen et al., in press). These findings suggest that “joint commitment” - formerly thought to be a unique component of human joint action - is present in other great apes, highlighting their communicative flexibility and emotional intelligence.

WHAT

WE STUDY

  • What cognitive and emotional mechanisms drive joint commitment and social success?

  • What are the evolutionary and developmental roots of joint action?

  • How do emotions (and expressions thereof) shape cooperation?

  • How do human communication and collaboration compare to our closest relatives?

  • Is there evidence for an interactional basis for language, i.e., a pre-linguistic basis that preceded the evolution of language? Recent comparative evidence suggests there is, but can we pinpoint the uniquely derived elements of this engine in humans, versus those that are phylogenetically shared or convergently derived?

Revisiting the human 'interaction engine": comparative approaches to social action coordination

The evolution of language was likely facilitated by a special predisposition for social interaction, involving a set of communicative and cognitive skills summarized as the ‘interaction engine'. This assemblage seems to emerge early in development, to be found universally across cultures, and to enable participation in sophisticated joint action through the addition of spoken language. Yet, new evidence on social action coordination and communication in nonhuman primates warrants an update of the interaction engine hypothesis, particularly with respect to the evolutionary origins of its specific ingredients. However, one enduring problem for comparative research results from a conceptual gulf between disciplines, rendering it difficult to test concepts derived from human interaction research in nonhuman animals. The goal of this theme issue is to make such concepts accessible for comparative research, to promote a fruitful interdisciplinary debate on social action coordination as a new arena of research, and to enable mutual fertilization between human and nonhuman interaction research. In consequence, we here consider relevant theoretical and empirical research within and beyond this theme issue to revisit the interaction engine's shared, convergently derived and uniquely derived ingredients preceding (or perhaps in the last case, succeeding) human language.

Impact of social context on human facial and gestural emotion expressions (2024)

Humans flexibly adapt expressions of emotional messages when interacting with others. However, detailed information on how specific parts of the face and hands move in socio-emotional contexts is missing. We identified individual gesture and facial movements (through automated face tracking) of N = 80 participants in the UK, produced while watching amusing, fearful, or neutral movie scenes either alone or with a social partner. Amusing and fearful scenes, more so than neutral scenes, led to an overall increase in facial and gesture movements, confirming emotional responding. Furthermore, social context facilitated movements in the lower instead of upper facial areas, as well as gesture use. These findings highlight emotional signaling components that likely underwent selection for communication, a result we discuss in comparison with the nonhuman primate literature. To facilitate ecologically valid and cross-cultural comparisons on human emotion communication, we additionally offer a new stimuli database of the recorded naturalistic facial expressions.
