Resum
Animals moving together in groups are believed to interact among each other with effective social forces, such as attraction, repulsion and alignment. Such forces can be inferred using 'force maps', i.e. by analysing the dependency of the acceleration of a focal individual on relevant variables. Here we introduce a force map technique for alignment depending on relative velocities between an individual and its neighbours. After the force map approach is validated with an agent-based model, we apply it to experimental data of schooling fish, where we observe signatures of an effective alignment force with faster neighbours, and an unexpected anti-alignment with slower neighbours. Instead of an explicit anti-alignment behaviour, we suggest that the observed pattern is a result of a selective attention mechanism, where fish pay less attention to slower neighbours. We present support for this hypothesis both from agent-based modeling, as well as from exploring leader-follower relationships between faster and slower neighbouring fish in the experimental data.
