However, humans are probably the only species who applies artificial ornaments. Such deliberate alterations of the skin, e.g., tattoos and scarring patterns, have been discussed by researchers as potential handicap signals, but there is still very little information about a potential biological signaling value of body modification. In this study eye-tracking was employed to investigate the signaling value of tattoos and other body modification. Measurement of gaze duration of 50 individuals while watching plain, scarred, accessorized, and tattooed bodies of artificial human images indicated that participants looked significantly longer at tattooed than at scarred, accessorized, and plain bodies. Generally, male participants paid more attention to tattooed stimuli of both sexes. More detailed analyses showed that particularly female tattooed stimuli were looked at longer. These findings are discussed within an evolutionary framework by suggesting that tattoos might have some signaling value which influences the perception of both male and female conspecifics and may hence also affect mating decisions."],["dc.identifier.doi","10.2466/pms.104.4.1337-1349"],["dc.identifier.gro","3150868"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/86009"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-425"],["dc.notes.status","final"],["dc.relation.eissn","1558-688X"],["dc.relation.issn","0031-5125"],["dc.title","Visual Attention to Plain and Ornamented Human Bodies: An Eye-Tracking Study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

It can be observed in many animals, such as bird flocks, shoals or herds of ungulates. Spatial attraction between humans as the central component of flocking behaviour has been simulated in a number of seminal models but it has not been detected experimentally in human groups so far. The two other sub-processes of this self-organised collective movement - collision avoidance and alignment - are excluded or held constant respectively in this study. We created a computer-based, multi-agent game where human players, represented as black dots, moved on a virtual playground. The participants were deprived of social cues about each other and could neither communicate verbally nor nonverbally. They played two games: (1) Single Game, where other players were invisible, and (2) Joint Game, where each player could see players' positions in a local radius around himself/herself. We found that individuals approached their neighbours spontaneously if their positions were visible, leading to less spatial dispersion of the whole group compared to moving alone. We conclude that human groups show the basic component of flocking behaviour without being explicitly instructed or rewarded to do so."],["dc.identifier.doi","10.1016/j.beproc.2012.09.004"],["dc.identifier.pmid","23041055"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/15400"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.eissn","1872-8308"],["dc.relation.eissn","0376-6357"],["dc.title","Spontaneous flocking in human groups"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

Specifically, we argue that studies of captive animals should only be used to elucidate behavioural mechanisms. Moreover, the diversity of physical environments in which group movements occur as well as the social diversity of groups deserve more consideration in integrative studies. Furthermore, tests of predictions based on modelling studies are often hampered by the fact that models include variables that are difficult or impossible to measure in real animals. We also advocate the use of an empirical, rather than subjective establishment of operational definitions of group movements and the associated individual roles. Finally, we emphasize the utility of controlled experiments in the study of collective decision-making and group movements and encourage their wider application."],["dc.identifier.doi","10.1016/j.beproc.2010.02.025"],["dc.identifier.gro","3150898"],["dc.identifier.pmid","20211229"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7696"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0376-6357"],["dc.subject","Group coordination; Leadership; Group movements; Primates; Decision-making"],["dc.title","Conceptual and methodological issues in the comparative study of collective group movements"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

Because individuals have different preferences and diverging needs, conflicts of interests exist; these conflicts are particularly revealed and negotiated in the context of group movements. Thus, group movements provide an excellent example to study coordination processes in non-human primates. In this chapter we review several aspects related to group movements in non-human primates. We first summarise the current understanding of variation in spacing patterns, types of leadership, and decision-making processes. We then focus on methodological issues and discuss various operational definitions of group movements, and we propose an operational definition that has already been applied successfully in studies of small free-ranging groups. We conclude by discussing the possibilities and limitations of transferring concepts and methods from studies of non-human primate groups to research on human groups."],["dc.identifier.doi","10.1007/978-3-642-15355-6_3"],["dc.identifier.gro","3150814"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/13193"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.publisher","Springer"],["dc.publisher.place","Berlin"],["dc.relation.doi","10.1007/978-3-642-15355-6"],["dc.relation.isbn","978-3-642-15354-9"],["dc.relation.ispartof","Coordination in Human and Primate Groups"],["dc.title","Coordination of Group Movements in Non-human Primates"],["dc.type","book_chapter"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]
