“…In particular, consonant with both Hagen and colleagues' signaling theory and their approach grounded in evolutionary biology, investigators have documented the importance of synchronized behavior in coalitional signaling and aggression in a number of species, including cetaceans (Connor et al, 2006; Cusick & Herzing, 6 2014;Perelberg & Schuster, 2008;Senigaglia & Whitehead, 2012;, birds (Hall & Magrath, 2007), and primates (Fedurek et al, 2013).…”

Synchronized behavior is a common feature of martial drills and military parades in many societies. Hagen and colleagues Hagen & Hammerstein, 2009) hypothesized that the intentional enactment of synchronized behavior evolved as a means of signaling coalitional strength, as individuals who can synchronize are able to act in concert in agonistic contexts. Previous research has explored either the subjective consequences of synchrony for participants in synchronized behaviors or the effect of synchrony on observers' impressions of rapport among the synchronized actors. Critically, left untested is the central tenet that, by communicating that the individuals constitute a coordinated unit, synchronized behaviors signal elevated fighting capacity. We tested this prediction in two studies by asking large U.S. samples to judge the envisioned physical formidability -previously demonstrated to summarize assessments of diverse determinants of fighting capacity -of U.S. soldiers or terrorists on the basis of audio tracks of either synchronous or asynchronous footsteps.Consonant with the agonistic signaling hypothesis, participants judged the synchronized target individuals to be larger and more muscular than the unsynchronized individuals, an effect mediated by their assessment that the former collectively constitute a single unified entity.Although synchronized footsteps also enhanced listeners' perceptions of social bonding among the target individuals, this assessment did not mediate their judgments of elevated formidability, suggesting that synchrony primarily signals fighting capacity via revealed entitativity rather than inferred motivation.Keywords: synchrony; signaling; fighting capacity; entitativity; perceived coalitional quality 2 1.0 Introduction 1.1 Synchronized behavior: theory and prior research. Across widely diverse cultures, and among societies of very different scales, synchronized behavior is a prominent feature of rituals and collective displays. Over the last two decades a growing literature has explored the psychological effects of synchronized movement and synchronized sound production (reviewed in Keller et al., 2014). At an elementary level, the effects of synchrony can be dichotomized into two classes, namely the impact that synchrony has on participants in such activities, and the impact that it has on observers. In a seminal book, McNeill (1995) proposed that synchronized movement enhances social bonding among participants, and that, over the course of human history, this process has played a pivotal role in the rise of cooperation.Pushing the roots of synchrony even farther back in time, Hagen and colleagues Hagen & Hammerstein, 2009) argued that music and dance derive from phylogenetically ancient coordinated territorial defense signals; in humans, these signals were refined to communicate the size, cohesiveness, and capabilities of coalitions, as intentionally enacted synchronized behavior inherently requires both the ability and the motivation to effectively coordinate actions.

“…In a similar manner synchronized resting behavior in killer whales and synchronized diving in sperm whales have been linked to enhanced vigilance against predators (Heimlich-Boran, 1988;Whitehead, 1996). Synchronization for social facilitation has also been suggested for cetacean (Mann and Smuts, 1999;Connor et al, 2006;Senigaglia and Whitehead, 2011). Several studies report the importance of mother calf synchronization during the first months of the calf life (Mann and Smuts, 1999).…”

“…Synchronization has been reported as an anti-predator response in cetaceans to both predators and human (boat) presence (Heimlich-Boran, 1988;Norris and Dohl, 1980;Hastie et al, 2003;Senigaglia and Whitehead, 2011). Norris and Dohl (1980) report how spinner dolphins tend to swim in tighter and more synchronized groups under predation risk.…”

“…We analyzed the relationship between the dependent variables (number of synchronized pairs and proportion of synchronized breathing) and the explanatory variables using generalized linear models (GLM). We developed biologically relevant contrasting models based on a previous study (Table 1; Senigaglia and Whitehead, 2011). School size (defined as the total number of individuals including calves), behavioral state and TBV were found to be the most meaningful parameters in our previous study hence were used as explanatory variables in our models, adding a site (Strait of Gibraltar versus Cape Breton) effect.…”

a b s t r a c t Keywords: Synchronization Strait of Gibraltar Cape Breton Long finned pilot whales GLMM Synchronized swimming in cetaceans has been hypothesized to play a role in affiliative processes as well as anti-predatory responses. We compared observed variation in synchronized swimming at two research sites in relation to disturbance exposure to test these two hypotheses. This study describes and quantifies pair synchronization in long-finned pilot whales at the Strait of Gibraltar, Spain and Cape Breton, Canada. Synchronization differed depending on the behavioral state and the response is different in the two sites leading to the conclusion that environment can shape the occurrence and magnitude of certain behaviors. We also analyzed intra-population variations in synchronization among 4 social units of Pilot whales in the Strait of Gibraltar and the results of this study confirmed the affiliative role of synchronization and highlighted an influence of disturbance on synchronization. We can conclude that synchronization is a common behavior in long-finned pilot whales that allow for close proximity and rapid coordinated response of individuals, with the multiple functions of showing affiliation and reacting to disturbance..
