The aim of this study was to investigate the differences in social and allogrooming, as well as its relation with the sex of the individuals and their social status in groups of common marmosets born and raised in captivity at the Department of cognitive biology at the University of Vienna. 28 marmosets living in 3 family groups were examined, and grooming behavior data were gathered by means of focal sampling totaling 166.5 hours of observations and 666 observed grooming bouts. Results showed the difference when it comes to duration, but not frequency, of allogrooming as opposed to selfgrooming, and hard to reach body parts were targeted more in allogrooming, whereas easy to reach parts were targeted more while selfgrooming. There were no sex differences in allogroming. Grooming social network was constructed in order to assess the differences between dominant and subordinate individuals, and centrality measures showed dominant pairs to be the focal points of the grooming networks.
