“…As seen in multiple studies, a leader can either be an individual with a low threshold (e.g., hungrier individual) or an experienced one with accurate information (on territory, migration, food patches) ( Rands et al., 2003 ) ( King and Cowlishaw, 2009 ; Smith et al., 2016 ; Sueur and Petit, 2010 ). The collective responses of such groups have been extensively studied in vertebrates ( Couzin et al., 2005 ; King, 2010 ; Lusseau and Conradt, 2009 ; Pettit et al., 2015 ; Reebs, 2000 ; Roy and Bhat, 2017 ; Seppänen et al., 2011 ) but also in insects and in other invertebrates ( Colasurdo and Despland, 2005 ; Collignon et al., 2012 ; Dussutour et al., 2008 ; Hodgkin et al., 2017 ; McClure et al., 2011 ; Plenzich and Despland, 2018 ; Stroeymeyt et al., 2011 ; Zirbes et al., 2010 ). However, in these cases, individual movements (including change of direction) are collectively synchronized and individuals are constantly influencing each other ( Dyer et al., 2009 ; Lusseau and Conradt, 2009 ; Schultz et al., 2008 ), the extreme case being the queue following behavior ( Fernandez and Deneubourg, 2011 ).…”

Many social species are able to perform collective decisions and reach consensus. However, how the interplay between social interactions, the diversity of preferences among the group members and the group size affects these dynamics is usually overlooked. The collective choice between odourous and odorless shelters is tested for the following three groups of social cockroaches (Periplaneta americana) which are solitary foragers: naive (individuals preferring the odorous shelter), conditioned (individuals without preference), and mixed (combining, unevenly, conditioned, and naive individuals). The robustness of the consensus is not affected by the naive individuals' proportion, but the rate and the frequency of selection of the odorous shelter are correlated to this proportion. In mixed groups, the naive individuals act as influencers. Simulations based on the mechanisms highlighted in our experiments predict that the consensus emerges only for intermediate group sizes. The universality of these mechanisms suggests that such phenomena are widely present in social systems.

Learning is ubiquitous in animals: individuals can use their experience to fine-tune behaviour and thus to better adapt to the environment during their lifetime. Observations have accumulated that, at the collective level, groups can also use their experience to improve collective performance. Yet, despite apparent simplicity, the links between individual learning capacities and a collective's performance can be extremely complex. Here we propose a centralized and broadly applicable framework to begin classifying this complexity. Focusing principally on groups with stable composition, we first identify three distinct ways through which groups can improve their collective performance when repeating a task: each member learning to better solve the task on its own, members learning about each other to better respond to one another and members learning to improve their complementarity. We show through selected empirical examples, simulations and theoretical treatments that these three categories identify distinct mechanisms with distinct consequences and predictions. These mechanisms extend well beyond current social learning and collective decision-making theories in explaining collective learning. Finally, our approach, definitions and categories help generate new empirical and theoretical research avenues, including charting the expected distribution of collective learning capacities across taxa and its links to social stability and evolution. This article is part of a discussion meeting issue ‘Collective behaviour through time’.

“…and seemingly drive the rest of the group to follow their example. Seemingly is the proper qualifier, because although numerous studies have attempted to quantify the collective benefits of leaderfollower dynamics [1][2][3][4] and identify behavioral features that make certain organisms more likely to take the lead in different scenarios [5][6][7][8], it is rather difficult to prove that the organisms who act later are actually being influenced by the leader and are not merely making independent, albeit delayed, decisions [9,10]. Indeed, one can think of leader-follower behavior as a continuum, with organisms that blindly follow the leader at one extreme, and those that make independent decisions simply coinciding with the leader's at the other.…”

Time-separated Mutual Information Reveals Key Characteristics of Asymmetric Leader-Follower Interactions in Golden Shiners

Leader-follower modalities and other asymmetric interactions that drive the collective motion of organisms are often quantified using information theory metrics like transfer or causation entropy. These metrics are difficult to accurately evaluate without a much larger amount of data than is typically available from a time series of animal trajectories collected in the field or from experiments. In this paper, we use a generalized leader follower model to argue that the time-separated mutual information between two organism positions is a superior metric for capturing asymmetric correlations, because it is much less data intensive and is more accurately estimated by popular k-nearest neighbor algorithms than is transfer entropy. Our model predicts a local maximum of this mutual information at a time separation value corresponding to the fundamental reaction timescale of the follower organism. We confirm this prediction by analyzing time series trajectories recorded for a pair of golden shiner fish circling an annular tank.
