The social organization of a species can also influence juvenile social play. We examined the relationships among play behaviors, candidate play signals, and play bout termination in Tibetan macaques （Macaca thibetana） during juvenile and infant social play to characterize the species play style. As Tibetan macaques are despotic and live in groups with strict linear dominance hierarchies and infrequent reconciliation, we predicted that play would be at risk of misinterpretation by both the individuals engaged in the play bout and by those watching, possibly leading to injury of the players. Animals living in such societies might need to frequently and clearly signal playful intent to play partners and other group members to avoid aggressive outcomes. We gathered video data on 21 individually-identified juvenile and infant macaques （one month to five years of age） from the Valley of the Wild Monkeys, Mt. Huangshan, China. We used all-occurrence sampling to record play behaviors and candidate play signals based on an ethogram. We predicted that play groups would use multiple candidate play signals in a variety of contexts and in association with the number of audience members in proximity to the players and play bout length. In the 283 playful interactions we scored,juvenile and infant macaques used multiple body and facial candidate play signals. Our data showed that juvenile and infant Tibetan macaques use a versatile repertoire of play behaviors and signals to sustain play展开更多

Animals play only if they are in a relaxed state. Play may improve adaptability to challenging environments which may be of interest in the breeding objective. Little information is available on play behavior in livestock species. The aim of the present study is to investigate whether play behavior in post-weaned piglets can be induced instantly in the presence of additional space and whether play markers are body weight, sex, and litter dependent, it is investigated whether playfulness is elicited by the moment or if this measure is consistent over different days. Methods： Thirty two piglets from four litters were released into a corridor and video recorded for eight min at 37, 41, 44 and 48 d of age. The first test was considered as an adjustment period and was not included in the analysis. In the second to the fourth test, joyful brusque movements （jumping, turning and running） were recorded with a camera and total number of movements （JOY#） and total time （JOYtime） were estimated individually. Animals were weighed at 41 d of age. Results： Females had higher scores of JOY# and JOYtime than males but this was significant only for JOY# at 41 d of age （P 〈 0.05）. The effect of age was highly significant both for JOY# and JOYtime （P 〈 0.01）. Animals with a higher JOY# and JOYtime also expressed a higher JOY# and JOYtime in the other tests, but this was significant only between 44 and 48 d of age （P〈 0.01）. Body weight at 41 d of age was not significantly related to JOY# and JQYtime in any of the tests. Conclusions： Locomotor play was induced instantly by the provision of increased space allowance. Litter origin had a significant effect on play behavior. In addition, locomotor play scores were consistent between two of the three tests.展开更多

Animals were weighed at 41 d of age. Results： Females had higher scores of JOY# and JOYtime than males but this was significant only for JOY# at 41 d of age （P 〈 0.05）. The effect of age was highly significant both for JOY# and JOYtime （P 〈 0.01）. Animals with a higher JOY# and JOYtime also expressed a higher JOY# and JOYtime in the other tests, but this was significant only between 44 and 48 d of age （P〈 0.01）. Body weight at 41 d of age was not significantly related to JOY# and JQYtime in any of the tests. Conclusions： Locomotor play was induced instantly by the provision of increased space allowance. Litter origin had a significant effect on play behavior. In addition, locomotor play scores were consistent between two of the three tests.
文摘n nonhuman animals,the phenomenon of rapid facial mimicry(RFM)—the automatic,involuntary,and rapid(<1 s)replication of others’facial expressions—has been mainly investigated in the playful domain.In immature lowland gorillas Gorilla gorilla gorilla both play face(PF)and full PF(FPF)are rapidly mimicked between the players.This makes the species suitable to test hypotheses on the factors influencing RFM during play.The observations on 3 captive groups of lowland gorillas(N=27)revealed that contrary to expectations,the closeness of social bond negatively influenced the occurrence of RFM but it did not affect either RFM latency or its overlapping index(OVERLAP).RFM was affected by the degree of symmetry of play fighting:the more balanced the session,the higher the occurrence of RFM.Players of the same sex class responded faster than players of different sex.These findings suggest that RFM may help synchronizing behaviors of playmates matching in size(same-sex)and promote symmetric playful interactions.“Laughing together”(measured by the RFM OVERLAP)lasted longer when the responder perfectly mirrored the partner expression(PF→PF;FPF→FPF).If PF and FPF convey information on the different play roughness degree,through“laughing together”the players could coordinate their actions and share positive moods and playful intensity.If the perfect congruency in the motor resonance,also known as social sensitivity,can foster a possible emotional dialogue between gorillas remains to be investigated.
