Observed and predicted responses to multiple neighbours.
Top row Observed (left) and predicted (right) acceleration response in groups of three individuals. Bottom row Observed (left) and predicted (right) turning responses. Predicted responses are calculated by combining the observed responses in simulations with two individuals (one single neighbour) under the assumption that the combined effect of two neighbours is equal to the average of two independent pairwise responses. White squares in the grids on the left indicate missing values, never occurring in the simulations.
