The evolution of aggressive and amicable play fighting in primates
Play fighting involves competing for an advantage, which can be derived from behavior typical of conspecific aggression, predation, sexual and other affinitive contexts. Here the phylogenetic distribution of aggressive play fighting (involving biting) and amicable play fighting (involving grooming and mounting) in juveniles of 48 species of primates was analyzed. Both aggressive and amicable play fighting were likely equally present in ancestral …
Rough-and-Tumble Play
The role of play in human development has long been the subject of controversy. This book examines the development of children's play through a rigorous and multidisciplinary approach.
The organization of play fighting in the grasshopper mouse (Onychomys leucogaster)
The body targets contacted, the type of contact made, and the patterns of defense and counterattack elicited by those attacks are examined in the play fighting of captive male and female pairs of grasshopper mice. The nape was the most frequently contacted body target, irrespective of the type of contact made, be it nosing, allogrooming, biting, or striking with a forepaw. The types of defense varied with both body area contacted and type of atta…
Targets, tactics, and the open mouth face during play fighting in three species of primates
The play fighting of many mammals involves the nonserious use of behavior patterns derived from serious fighting. A major question of theoretical importance has been that of how, given this overlap in patterns of behavior, the animals can distinguish between playful and nonplayful intent. One proposed solution is that animals use play signals to inform each other about the playful intent of their actions. The most widely reported play signal amon…
Influence of dominance on the development of play fighting in pairs of male Syrian golden hamsters (Mesocricetus auratus)
In the highly social rat, male juvenile and adult subordinates initiate more playful contacts with dominant pairmates than vice versa. This study examined the effect of dominance on playful contacts in the relatively asocial golden hamster. Pairs of male hamsters were reared together from weaning, and their play was filmed in the juvenile (28-36 days) and the young adult (60-70 days) stages of development. By the adult stage, it became clear that…
Analysis of the targets and tactics of conspecific attack and predatory attack in northern grasshopper miceonychomys leucogaster
Comparisons of tactics of fighting between species are often difficult to make since the body targets attacked may differ. Thus it becomes difficult to assess whether differences in fighting tactics are due to species-specific differences in the tactics themselves or due to the different targets attacked. A solution to this problem is to analyse the tactics of a species that attacks different targets under different circumstances. In this way, di…
Neonatal testosterone augmentation increases juvenile play fighting but does not influence the adult dominance relationships of male rats
Neonatal male rats were either injected subcutaneously with testosterone propionate (TP) or oil vehicle. When weaned, each treated pup was paired with an untreated male sibling. The play fighting of TP-and oil-treated rats were compared at the juvenile phase (30–36 days), and in adulthood (84–90 days). In the juvenile phase, the rate of initiating playful attacks was significantly greater for TP-treated rats. Playful defense in response to such a…
Disentangling the contribution of the attacker from that of defender in the differences in the intraspecific fighting in two species of voles
In a previous study we found that in the intraspecific, resident-intruder fights of males of two vole species there were significant differences in the frequency of use of some of the behavior patterns used for attack and defense. To determine whether the species differences were due to differences in the behavior of the attacker (resident), defender (intruder), or some combination of both, a detailed frame-by-frame analysis of videorecorded sequ…
Juvenilized play fighting in subordinate male rats
As pairs of male juvenile sibling rats that are housed together become sexually mature, they develop a dominance-subordinance relationship. These dominance relationships appear to be reflected in the play fighting of the pairmates both as juveniles and as young adults, in that the seemingly subordinate partner initiates more playful attacks at both ages. However, as adults, even though it is the subordinate that initiates more playful attacks, it…
Supine defense in the intraspecific fighting of male house micemus domesticus
House mice have been reported rarely to perform the supine behavior pattern as a defensive tactic during intraspecific fighting. However, in this study of intraspecific fighting by male mice, it is shown that mice do indeed rotate to supine. This maneuver is used to evade or extricate themselves from bites to the lower dorsum by the attacking opponent. Once free from the bite the defender does not remain supine, but will immediately turn to prone…
Role reversal changes during the ontogeny of play fighting in male rats
From weaning until sexual maturity, the rates at which young male rats hold each other supine during play fighting appear to become progressively asymmetrical. These changes have been previously thought to reflect an initial lack of dominance and a later development of dominance-subordinance relationships. In this paper it is shown that pairs of male rats exhibit asymmetries in playful attack and playful defense throughout development. The change…
Targets and tactics of agonistic and precopulatory behavior in montane and prairie voles
Play-fighting by juvenile montane and prairie voles involves attack and defense of the head, neck and shoulders. Since during play animals typically borrow behavior patterns from other functional contexts, two adult behavioral contexts were compared to juvenile play-fighting. These were serious fighting and sexual encounters. During serious fighting in a resident-intruder paradigm, most bites are directed at the rump and lower flanks. During sexu…
Different levels of complexity in the play‐fighting by muroid rodents appear to result from different levels of intensity of attack and defense
Play‐fighting in deer mice, Peromyscus maniculatus bairdii , prairie voles, Microtus ochrogaster , and montane voles, M. Montanus , was compared to that of laboratory rats, Rattus norvegicus . Play in rats appears more complex for two reasons: 1) more of the playful contacts elicit defensive behaviors, and 2) more of these defenses lead to counterattacks, and hence, role reversals between attackers and defenders. Neither high levels of defense, a…
Targets of attack and defense in play-fighting of the Djungarian hamsterPhodopus campbelli
Analysis of the body targets attacked and defended during play-fighting by juvenile Djungarian hamsters Phodopus campbelli revealed that about 70% of all attacks were directed at the mouth. If successfully contacted, the mouth was briefly licked and nuzzled. The remaining playful attacks were gentle bites directed at the rump, and to a lesser extent, the top of the head. During serious fighting the top of the head and the rump are targets of atta…
Identification of the possible origin of the body target that differentiates play fighting from serious fighting in syrian golden hamsters (Mesocricetus auratus)
Play fighting in the Syrian Golden hamster Mesocricetus auratus can be distinguished from serious fighting by the targets attacked in each case. In play fighting, the animals attack and defend the cheeks and cheek pouches, whereas in serious fighting they attack and defend the rump and lower flanks. Since play typically involves the use of behaviors borrowed from other functional contexts, this paper investigates the origin of the cheek target du…
Play-fighting differs from serious fighting in both target of attack and tactics of fighting in the laboratory ratRattus norvegicus
Play-fighting is often difficult to differentiate from inhibited or immature serious fighting because both may utilize many of the same behavior patterns. In the rat the two behaviors involve different targets of attack. During play-fighting, snout or oral contact is directed at the opponent's nape of the neck, whereas during serious fighting, male residents mostly direct their bites at the intruder's rump. Although similar to those used in serio…
