What is play fighting and what is it good for?
Open accessAbstract
Play fighting is a common form of play reported among species of mammals, birds, and some other taxa. The competition present in play fighting revolves around gaining some advantage, such as biting a partner without being bitten. The behavior simulated during play fighting need not be restricted to that present in adult serious fighting, but can involve competitive interactions derived from amicable behavior, such as sex and social grooming, or from nonsocial competition, such as predation. What unifies play fighting, irrespective of the functional behavior being simulated, is that it involves some degree of reciprocity, or turn taking, that requires that the competition be attenuated by cooperation. However, there are several different ways in which cooperation can be inserted into playful interactions, and these vary in use across different species. The moderation of competition with cooperation forces animals to monitor their own actions and those of their partners, and this common feature appears to be one vehicle through which the experience of play fighting in the juvenile period can train animals for greater psychological resilience. The monitoring and contextual adjustment of actions influences the development of executive functions of the brain, which, in turn, leads to the development of more adaptable adults.

Social play behavior is a precursor of adult social, aggressive, and sexual behavior and functions to facilitate the development of circuits involved in social behavior.
“It is thought that social play behavior is a precursor of adult social, aggressive, and sexual behavior that is displayed out of context, in exaggerated form and functions to facilitate the development of circuits involved in social behavior (Panksepp, 1981; Vanderschuren and Trezza, 2014; Pellis and Pellis, 2017).”
From Effects of Maternal Deprivation and Complex Housing on Rat Social Behavior in Adolescence and Adulthood (2018) · cites this paper as Pellis and Pellis, 2017
In “The functions of play fighting” (page unavailable), the paper says play fighting can influence brain executive functions and social skills, supporting the developmental part of the claim. But it questions whether play generally prepares animals for adult fighting: the suitability of play as combat practice varies by species, and the paper does not establish it as a precursor of adult social, aggressive, and sexual behavior as a whole.

Experimental — accuracy not yet measuredRats have a degree of sophistication in their rough-and-tumble play comparable to that of many primates and other social mammals.
“rats have a degree of sophistication in their RTP that is comparable to that of many primates and other social mammals (Pellis and Pellis, 2017)”

In “The many routes to restraint during play fighting” (page unavailable), the paper describes rats’ tactical role reversals and reports a similar pattern in spider monkeys and macaques. This supports a comparison with some primates, but it does not establish comparable overall sophistication across many primates and other social mammals. (LLM, conf=0.82)

The Abstract (page not supplied) says play fighting may build psychological resilience, supporting the possibility that it is beneficial. The functions of play fighting section (page not supplied) says excessive force can cause play to escalate into serious fighting, but does not establish that excess agonistic engagement between cage mates harms wellbeing. (LLM, conf=0.84)
Experimental — accuracy not yet measuredIn play fighting, the player with the advantage may voluntarily relinquish it, allowing a role reversal in which the original defender can become the attacker.
“That is, the player with the advantage may voluntarily relinquish it, thus allowing a role reversal to occur, with the original defender gaining the opportunity to become the attacker (Pellis and Pellis, 2017).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
