Rough‐and‐tumble play and the regulation of aggression: an observational study of father–child play dyads

Rough‐and‐tumble play (RTP) is a common form of play between fathers and children. It has been suggested that RTP can contribute to the development of selfregulation. This study addressed the hypothesis that the frequency of father–child RTP is related to the frequency of physically aggressive behavior in early childhood. This relationship was expected to be moderated by the dominance relationship between father and son during play. Eighty‐five children between the ages of 2 and 6 years were videotaped during a free‐play session with their fathers in their homes and questionnaire data was collected about father–child RTP frequency during the past year. The play dyads were rated for the degree to which the father dominated play interactions. A significant statistical interaction revealed that RTP frequency was associated with higher levels of physical aggression in children whose fathers were less dominant. These results indicate that RTP is indeed related to physical aggression, though this relationship is moderated by the degree to which the father is a dominant playmate. Aggr.

ENHANCING THE EFFECTIVENESS OF A PLAY INTERVENTION BY ABOLISHING THE REINFORCING VALUE OF STEREOTYPY: A PILOT STUDY

An alternating treatments design compared one condition in which a child with autism was allowed to engage in stereotypy freely prior to the intervention (abolishing operation component) to a second condition without the free‐access period. Levels of stereotypy and problem behavior were lower and levels of functional play were higher in the condition with the abolishing operation component. These data provide preliminary support for the use of abolishing operations in interventions to increase the play skills of children with autism.     

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 amongst primates is the open mouth play face. The manner in which this so-called signal functions is based on correlational evidence, with most reports simply noting its presence or absence in a given species. This study involved a detailed video-based analysis of the occurrence of open mouths during the play fighting of three species of primates. One captive troop each of ring-tailed lemurs, black-handed spider monkeys, and patas monkeys was used. By examining all open mouths in the context of the species-typical style of play fighting, several conclusions were empirically verified. 1) Most open mouths occur as a functionally necessary precursor for biting. 2) Some open mouths occur as a defensive threat which deters further contact. 3) The residual open mouths which may function as contact promoting play signals, constituted about 20–25% of all open mouths by the lemurs and patas monkeys, but less than 5% for spider monkeys. These species differences appeared to arise from two causes. Firstly, the spider monkeys used another signal, the head shake, in situations where lemurs and patas monkeys used open mouths. Secondly, the style of play fighting greatly influenced the frequency and duration of open mouths. This was most marked in the face-to-face combat style of patas monkeys. These findings show that comparative studies of the occurrence and function of play signals need to take into account species-typical styles of playful combat. Aggr.

Sharing Attention to Toys: Adolescent Mother–Toddler versus Adult Mother–Toddler Dyads

This study examined whether there were differences in the joint attention behaviours of adolescent mothers and toddlers and adult mothers and toddlers. The timing of mothers' attention-directing behaviours (i.e. maintaining, introducing and redirecting) as well as the specific behaviours (i.e. showing, offering and demon-strating toy) they used to direct their toddlers' attention to toys were observed. The observers also coded the specific joint attention behaviours that the toddlers used. The findings showed that the adolescent mothers redirected their toddlers' attention away from a toy they were interested in to a different toy more often and used fewer introducing behaviours than the adult mothers. Toddler age was also inversely related to mothers' redirecting behaviour. The results also indicated that the adolescent mothers demonstrated toys and interfered with their toddlers' ongoing play behaviour more frequently than the adult mothers. Toddler age was also inversely related to the frequency with which both groups of mothers demonstrated toys and positively related to the frequency with which mothers showed toys. The toddlers born to the adolescent mothers showed fewer social initiations and a higher frequency of non-verbal responses than the toddlers born to the adult mothers. Toddler age was negatively related to the frequency of non-verbal responses.     

Transfer of Responsibility in Parent–Child Play During the Second Year

The purpose of the present study was to examine changes in parental support for play during the toddler's second year. Thirty toddlers and their parents were observed when the toddlers were 13,14,20 and 21 months of age. Parents' production of facilitating behaviours and exploratory play increased over time, whereas their production of combinatorial, symbolic and sequential play decreased. Correlational and sequential analyses indicated that, at the early visits, parents responded to their toddlers' combinatorial and symbolic play with similar types of play, whereas at the later visits, only symbolic play was followed by comparable actions. Sensitive parents ‘transfer responsibility’ for play actions as they believe their toddlers become more competent. © 1996 John Wiley & Sons, Ltd.     

Fighting and playfighting in captive adolescent chimpanzees

Most young non-human primates spend a great deal of time playing alone or with conspecifics. Despite numerous studies on social play, its adaptive functions remain unclear. A longitudinal study comparing social interactions preceding and following rank reversals among four captive adolescent chimpanzees (Pan troglodytes schweinfurtii) suggests that social play during their adolescent period functioned in establishing and maintaining the dominance rank within dyads, without interventions from allies. Interventions were less frequent in rough-and-tumble play than in real fighting. Within dyads of competing chimpanzees, rough play was more frequent than gentle play. Both types of play were correlated with reciprocal aggression between competitors, and most play bouts terminated in truly aggressive conflict. Dominant individuals seemed to be responsible for maintaining play activity, by responding playfully to threats and aggression of contestants. In addition, dominant individuals more often initiated play encounters with their subordinates when the dominance relationships were clear, but subordinate individuals also initiated play sequences when they challenged the dominant's rank. The adaptive value and mechanisms of rough-and-tumble play are discussed in the context of adolescence. © 1994 Wiley-Liss, Inc.     

“Hands Off the Car, It’s Mine!” and “The Teacher Will Be Angry if We Don’t Play Nicely”: Gender-Related Preferences in the Use of Moral Rules and Social Conventions in Preschoolers’ Dyadic Play

The aim of the present study was to examine the moral and conventional rules in 40 same-sex and same-age 4- and 5-year-old preschoolers’ dyads during their play interaction. Significant gender differences were found both in the dominant social domain and in the prevailing types of rules within each domain. Boys referred to moral rules more often than girls did. In the category of moral rules, boys were significantly more likely to bring up justice and rights issues than girls were. In the category of conventional rules, girls focused on miscellaneous and general conventions and boys on the destruction of property. Moral rules were applied more frequently in conflict situations. Regardless of gender, the rules of justice were the most likely moral rules to engender conflicts.     

Minding Animals, Minding Earth: Old Brains, New Bottlenecks

Abstract. I emphasize the importance of broadening behavioral, ecological, and conservation science into a more integrative, interdisciplinary, socially responsible, compassionate, spiritual, and holistic endeavor. I stress the significance of studies of animal behavior, especially ethological research concerned with animal emotions in which individuals are named and recognized for their own personalities, for helping us to learn not only about the nonhuman animal beings with whom we share Earth but also about who we are and our place in nature. We are best understood in relationship with others. To this end I develop the notions of “minding animals” and “deep ethology.” Animals are sources of wisdom, a way of knowing. We are all citizens of Earth, members of a global community in which intimate reciprocal and beneficent peaceful relationships are mandatory. A world without cruelty and with boundless compassion, respect, grace, humility, spirituality, and love would be a better world in which to live. We have compelling responsibilities for making Earth a better and more peaceful habitat for all beings. It is essential that we do better than our ancestors. We must reflect and step lightly as we “redecorate” nature. Time is not on our side. I plead for the development of heartfelt and holistic science that allows for joy and play. Science need not be suspicious of things it cannot fully understand. We must not avert our eyes or other senses from the eyes and voices of other beings who urgently need our uncompromising and unconditional aid and love. We can do much more than we have done for animals and the Earth.
