Impact of Aggression on Bystanders: Quadratic Post‐Conflict Affiliation in Chimpanzees (<i>Pan troglodytes</i>) Open
In social animals, aggression is a group matter not involving only the opponents. Witnessing a conflict can induce tension and distress in bystanders (i.e., individuals not involved in either the conflict or post‐conflict affiliation with …

Rapid mimicry of trunk and head movements during play in African Savanna elephants (Loxodonta africana) Open
The basic forms of motor and possibly emotion replication include behavioral contagion and rapid motor mimicry (RMM). RMM—mainly demonstrated during play—occurs when an individual perceives and rapidly (< 1 s) replicates the exact motor se…

Functional and Morphological Differences in the Play Face and Full Play Face in Lowland Gorillas, a Hominid Species: Implications for the Evolutionary Roots of Smile and Laugh Face Open
Objective Play Face (PF) and Full Play Face (FPF) in the great apes—homologous to human smile and laugh‐face—have been considered a single phenomenon. However, if natural selection has preserved two expressions, probably their adaptive val…

Is it a Match? Yawn Contagion and Smile Mimicry in Toddlers Open
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 (wit…

Nose-clip use in semi-free ranging pigs reduces rooting without disrupting affiliative behaviour or causing prolonged stress Open
Domestic pigs (Sus scrofa) raised under natural conditions can show their complete behavioural repertoire. However, rooting behaviour can have a great impact on the environment. In the context of the promotion of farm animal welfare and en…

Balancing welfare and habitat damage in pigs (Sus scrofa) under extensive farming: an ethological approach for determining the effects of group composition and environmental enrichment Open
According to the modern perspective on evaluating animal welfare, it is important to consider both negative and positive experiences. This study investigated the impact of group composition and environmental enrichments on the behaviours o…

Social play in African savannah elephants may inform selection against aggression Open
In social groups, competition for individual advantage is balanced with cooperation, for the collective benefit. Selection against aggression has favored cooperation and non-aggressive competitive strategies. Because social play is a behav…

Is it for real? Structural differences between play and real fighting in adult chimpanzees (<i>Pan troglodytes</i>) Open
In primates, as well as in other mammals, play fighting (PF) is a complex form of playful activity that is structurally similar to real fighting (RF) and may also be used in a competitive way. Here, we verify the structural key differences…

Sows’ Responses to Piglets in Distress: An Experimental Investigation in a Natural Setting Open
Domestic pigs (Sus scrofa) possess complex socio-cognitive skills, and sows show high inter-individual variability in maternal behaviour. To evaluate how females—reared under natural conditions—react to the isolation calls of their own pig…

Witness for resolution: post-conflict quadratic affiliation in semi-free ranging pigs Open
In social mammals, post-conflict resolution can involve the reunion of former opponents (reconciliation), spontaneous/solicited post-conflict affiliation of a third party with either opponent (triadic contacts), and affiliation between oth…

Does the Domestication Syndrome Apply to the Domestic Pig? Not Completely Open
The ‘domestication syndrome’ defines a suite of features that domesticated animals possess as the result of the artificial selection operated by Homo sapiens since the Neolithic. An interesting anthropological question is whether such feat…

Playful interactions and facial mimicry in infant bonobos (<i>Pan paniscus</i>) Open
The capacity to promptly and congruently respond to others’ facial signals has at its basis a mirror neuron mechanism. In Rapid (< 1 sec, RFM) and Delayed (1–5 sec, DFM) Facial Mimicry the expression emitted by an individual (trigger) i…

Playing together, laughing together: rapid facial mimicry and social sensitivity in lowland gorillas Open
In 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 Go…

Anxiety Behavior in Pigs (Sus scrofa) Decreases Through Affiliation and May Anticipate Threat Open
Anxiety is a physio-psychological state anticipating an imminent threat. In social mammals it is behaviorally expressed via displacement activities and buffered via affiliation. Anxiety research on domestic pigs ( Sus scrofa ) has mostly f…

Earlier than previously thought: Yawn contagion in preschool children Open
Yawning is a primitive and stereotyped motor action involving orofacial, laryngeal, pharyngeal, thoracic and abdominal muscles. Contagious yawning, an involuntarily action induced by viewing or listening to others' yawns, has been demonstr…

Look at me while having sex! Eye-to-eye contact affects homosexual behaviour in bonobo females Open
In humans, eye-to-eye contact (EEC) or mutual gazing is a reflexive predisposition occurring in intimate contexts. We investigated the role of EEC during bonobo socio-sexual contacts. Females engage in homosexual ventro-ventral, genito-gen…

Intraspecific Motor and Emotional Alignment in Dogs and Wolves: The Basic Building Blocks of Dog–Human Affective Connectedness Open
Involuntary synchronization occurs when individuals perform the same motor action patterns during a very short time lapse. This phenomenon serves an important adaptive value for animals permitting them to socially align with group fellows …

Back to the Future: A Glance Over Wolf Social Behavior to Understand Dog–Human Relationship Open
This review focuses on wolf sociobiology to delineate the traits of cooperative baggage driven by natural selection (wolf-wolf cooperation) and better understand the changes obtained by artificial selection (dog-human cooperation). We sele…

Facial mimicry and play: A comparative study in chimpanzees and gorillas. Open
Play fighting, a common form of mammalian play, can escalate into aggression if playful motivation is misinterpreted and not shared by players. In primates, playful facial expressions and mimicry can be performed to signal and share playfu…

Fair play and its connection with social tolerance, reciprocity and the ethology of peace Open
The concept of peace, with its corollary of behaviours, strategies and social implications, is commonly believed as a uniquely human feature. Through a comparative approach, we show how social play in animals may have paved the way for the…
