Besides the fundamental role of social interaction rules, a combination of theoretical and empirical work indicates individual speed may be a key process that drives the collective behaviour of animal groups. Socially induced changes in speed by interacting animals make it difficult to isolate the effects of individual speed on group-level behaviours. Here, we tackled this issue by pairing guppies with a biomimetic robot. We used a closed-loop tracking and feedback system to let a robotic fish naturally interact with a live partner in real time, and programmed it to strongly copy and follow its partner's movements while lacking any preferred movement speed or directionality of its own. We show that individual differences in guppies' movement speed were highly repeatable and in turn shaped key collective patterns: a higher individual speed resulted in stronger leadership, lower cohesion, higher alignment and better temporal coordination of the pairs. By combining the strengths of individual-based models and observational work with state-of-the-art robotics, we provide novel evidence that individual speed is a key, fundamental process in the emergence of collective behaviour.</dcterms:abstract> <dc:contributor>Bierbach, David</dc:contributor> <dc:creator>Romanczuk, Pawel</dc:creator> <dc:contributor>Romanczuk, Pawel</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2020-09-18T13:53:03Z</dc:date> <dc:creator>Weimar, Nils</dc:creator> <dc:creator>Jolles, Jolle W.</dc:creator> <dc:rights>terms-of-use</dc:rights> <dc:creator>Bierbach, David</dc:creator> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/50902"/> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <dc:creator>Landgraf, Tim</dc:creator> <dc:contributor>Krause, Jens</dc:contributor> <dcterms:rights rdf:resource="https://rightsstatements.org/page/InC/1.0/"/> </rdf:Description> </rdf:RDF>
