Is it a Match? Yawn Contagion and Smile Mimicry in Toddlers
Automatic behavioral matching includes Rapid Facial Mimicry (RFM) and Yawn Contagion (YC) that occur when the facial expression of an individual acts as a 'mirror social releaser' and induces the same facial expression in the observer (within 1 s for RFM, and minutes for YC). Motor replication has been linked to coordination and emotional contagion, a basic form of empathy. We investigated the presence and modulating factors of Rapid Smile Mimicr…
Manual preference, performance, and dexterity for bimanual grass‐feeding behavior in wild geladas ( Theropithecus gelada )
We assessed whether wild geladas, highly specialized terrestrial grass eaters, are lateralized for bimanual grass‐plucking behavior. According to the literature, we expected that complex motor movements in grass feeding would favor the emergence of a population‐level hand bias in these primates. In addition, we described geladas' manual behavior based on systematic observations of several individuals. Our study group included 28 individuals belon…
Beware! Different methods lead to divergent results on yawn contagion modulation in bonobos
Contagious yawning (CY)—linked to physiological synchronization and possibly emotional contagion—occurs when one individual's yawn induces yawning in others. CY was investigated over different time windows (minutes from the triggering stimulus) via naturalistic or experimental studies (using real and video yawns, respectively) with contrasting results, especially in bonobos. We verified whether in bonobos result divergences may derive from differ…
Yawn contagion in bonobos: Another group, another story
In primates, yawn contagion (the yawning response elicited by others' yawn) is variably influenced by individual (e.g., sex, age) and social factors (e.g., familiarity) and possibly linked to interindividual synchronization, coordination, and emotional contagion. Two out of three studies on yawn contagion in bonobos ( Pan paniscus ), found the presence of the phenomenon with mixed results concerning the effect of familiarity and no replication on…
Wild geladas (Theropithecus gelada) in crops—more than in pasture areas—reduce aggression and affiliation
Human–primate interfaces are expanding and, despite recent studies on primates from peri-urban environments, little research exists on the impact of agriculture and/or pasture areas on primate social behavior and health. We assessed how crop/pasture areas potentially alter social behavior and health of wild geladas ( Theropithecus gelada ) frequenting the unprotected area of Kundi (Ethiopia). We predicted that compared to pasture areas, crop area…
Yawning Is More Contagious in Pregnant Than Nulliparous Women: Naturalistic and Experimental Evidence
Contrary to spontaneous yawning, which is widespread in vertebrates and probably evolutionary ancient, contagious yawning-yawning triggered by others' yawns-is considered an evolutionarily recent phenomenon, found in species characterized by complex sociality. Whether the social asymmetry observed in the occurrence of contagious yawning is related to social and emotional attachment and may therefore reflect emotional contagion is a subject of deb…
