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"]]

Because of their small body size, in combination with their solitary and nocturnal life style, it has been suggested that they mainly rely on crypsis to evade predators. However, recent studies revealed that nocturnal primates are not generally cryptic and that they exhibit predator-specific escape strategies as well as alarm calls. In order to add to this new body of research, we studied anti-predator strategies of nocturnal grey mouse lemurs experimentally. In order to elicit anti-predator behaviour and alarm calls, we conducted experiments with a carnivore-, snake- and raptor model. We also conducted playback experiments with mouse lemur alarm calls to characterize their function. In response to predator models, they exhibited a combination of anti-predator strategies: in response to carnivore and snake models, mouse lemurs monitored the predator, probably to assess the potential risk that emanates from the predator. In response to raptor models they behaved cryptically and exhibited freezing behaviour. All mouse lemurs, except one individual, did not alarm call in response to predator models. In addition, during playback experiments with alarm calls, recorded during real predator encounters, mouse lemurs did not emit alarm calls nor did they show any escape behaviour. Thus, as in other nocturnal primates/mammals, mouse lemurs do not seem to rely on routinely warning of conspecifics against nearby predators."],["dc.identifier.doi","10.1111/j.1439-0310.2010.01756.x"],["dc.identifier.gro","3150581"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7358"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0179-1613"],["dc.title","Anti-Predator Behaviour in a Nocturnal Primate, the Grey Mouse Lemur (Microcebus murinus)"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]
