Sexual and aggressive play fighting of sibling Richardson’s ground squirrels

Play fighting in many species of squirrels can involve sexual play and aggressive play, both of which can lead to wrestling which appears superficially similar. Such convergence can make scoring of the relative frequencies of these two types of play difficult and can lead to the mistaken conclusion that they grade into one another. In this study, both staged laboratory encounters between sibling pairs and spontaneous encounters between siblings in free‐living litters of Richardson’s ground squirrels (Spermophilus richardsonii) were videotaped. Frame‐by‐frame analyses using the Eshkol‐Wachman Movement Notation were employed to record the correlated movements of attack and defense by the partners and to reveal the body areas targeted during each play bout. Whereas sexual play was organized around access to the rump, aggressive play was organized around the shoulders. Although in most cases the defender’s tactics blocked access to the respective target, when contact did occur, it involved mounting in sexual play and nosing or biting in aggressive play. Eighty‐six percent of play fights could be unambiguously categorized as either sexual or aggressive play. Of these, the majority (?80%) involved sexual play. The sex of the participants did not affect the frequency of aggressive play, but in sexual play, males initiated more attacks than females. Once initiated, each form of play fighting remained distinct—if a bout began as sexual play, it would end as sexual play. Furthermore, a counterattack following sexual play was significantly more likely to be sexual than aggressive, and vice versa for counterattacks following aggressive play. Therefore, all the evidence suggested that the two forms of play fighting were not intermixed in Richardson’s ground squirrels. Aggr. Behav. 27:323–337, 2001. © 2001 Wiley‐Liss, Inc.     

Proximal and distal effects of play on child compliance with a brain-injured parent.

Individuals with brain injury may experience severe cognitive and other impairments. For brain‐injured parents, such deficits may be associated with child behavior problems, including noncompliance. We assessed the effects of a play period conducted by a brain‐injured father on the compliance of his son, who had become uncooperative with his father after the injury. The child consistently demonstrated improved compliance during proximal and distal compliance sessions that followed father‐son play periods.

Effects of Group Activity Play Therapy on Problem Behaviors of Preadolescent Ugandan Orphans

This randomized controlled study examined the effectiveness of group activity play therapy (GAPT) with 60 displaced Ugandan orphans, ages 10 to 12 years, exhibiting clinical levels of behavior problems. Teachers and housemothers reported that experimental group children demonstrated statistically significant reductions (p < .025) in behavior problems compared with children in the active control condition and that GAPT demonstrated moderate to large treatment effects. Results support GAPT as an effective intervention for troubled Ugandan orphans.     

To Play or Not to Play: Diverse Motives for Latino and Euro‐American Parent–Child Play in a Children's Museum

A popular social discourse in the United States is that play is important for children's learning and that parental involvement maximizes play's learning potential. Past research has concluded that parents who hold this view of play are more likely to play with their children than those who do not. This study investigated the prevalence of this view among Euro‐American and immigrant Latino parents of young children in order to illuminate the extent to which it uniquely and uniformly motivates parent–child play. Parents' models of play were assessed through interviews and naturalistic observations in a children's museum. Analysis revealed ethnic group differences in parent–child play that corresponded with parental beliefs about play. Within‐group analysis, however, revealed diversity in the ways that these play behaviours and beliefs came together to comprise parents' models of play. Discussion focuses on the social nature of play, the dynamic nature of culture, and the issue of individual subject validity. Implications for the interpretation of parent–child play in early childhood settings are considered. Copyright © 2014 John Wiley & Sons, Ltd.     

More than just child’s play: symbolic expressions of illness and spirit

While spiritual well-being is integral to health, little is known about the spiritual lives of children in the context of illness. Because the spiritual is often a hidden domain of life, exploration of the topic can be challenging, especially when dealing with children. Language is not always sufficient for describing such deeply held experiences, even for adults. Therefore, finding creative ways to elicit experiences of the spiritual is important when attempting to gain a more robust understanding of this phenomenon. Drawing from a larger study that used hermeneutic phenomenology to explore spirituality among ill children, this paper provides an interpretation of ill children’s play experiences and describes how these experiences provide a means of uncovering the spiritual in children’s everyday lives as they cope with life-threatening illness. Findings also provide insight into how play can be used in the promotion of spiritual well-being.

Reduced asymmetry in motor skill learning in left-handed compared to right-handed individuals

Hemispheric specialization for motor control influences how individuals perform and adapt to goal-directed movements. In contrast to adaptation, motor skill learning involves a process wherein one learns to synthesize novel movement capabilities in absence of perturbation such that they are performed with greater accuracy, consistency and efficiency. Here, we investigated manual asymmetry in acquisition and retention of a complex motor skill that requires speed and accuracy for optimal performance in right-handed and left-handed individuals. We further determined if degree of handedness influences motor skill learning. Ten right-handed (RH) and 10 left-handed (LH) adults practiced two distinct motor skills with their dominant or nondominant arms during separate sessions two–four weeks apart. Learning was quantified by changes in the speed–accuracy tradeoff function measured at baseline and one-day retention. Manual asymmetry was evident in the RH group but not the LH group. RH group demonstrated significantly greater skill improvement for their dominant-right hand than their nondominant-left hand. In contrast, for the LH group, both dominant and nondominant hands demonstrated comparable learning. Less strongly-LH individuals (lower EHI scores) exhibited more learning of their dominant hand. These results suggest that while hemispheric specialization influences motor skill learning, these effects may be influenced by handedness.     

Beyond sincerity and pretense: role-playing and unstructured self in the Zhuangzi

This article engages with a recent view that the Daoist Classic Zhuangzi advances an alternative to the Confucian role-ethics. According to this view, Zhuangzi opposes the Confucian idea that we should play our social roles with sincerity and instead argues that we should take the liberty to detach ourselves from the roles we play and ‘pretend’ them. It is argued in this article that Zhuangzi’s ideal of role-playing is based neither on sincerity nor on pretense. Instead, it is akin to the excellence of theatre actors when they enact a role: they are able, for a limited time, to restructure their personality into a particular role, but de-structure it again when the performance is over. The prerequisite for this ability is to keep one’s self fundamentally unstructured, or, as Zhuangzi puts it, ‘empty’ (xu 虛). This reading of Zhuangzian role-playing provides a fresh perspectives on ‘playing’ or ‘rambling’ (you 遊) as the central philosophical concept in the Zhuangzi.     

Factors Related to Play Therapists' Social Justice Advocacy Attitudes

The authors used a correlational research design to examine how belief in a just world, political ideology, socioeconomic status of family of origin, and percentage of racial minority clients were related to social justice advocacy attitudes among play therapists. A multiple regression was used to analyze the data. Results indicated that belief in a just world and political ideology were related to social justice advocacy. Implications for play therapy training and future directions for research are discussed. Los autores emplearon un diseño correlacional de investigación para examinar cómo la creencia en un mundo justo, la ideología política, el estatus socioeconómico de la familia de origen y el porcentaje de clientes de minorías raciales estaban relacionados con actitudes de apoyo de la justicia social entre consejeros que usan terapia de juego. Se empleó una regresión múltiple para analizar los datos. Los resultados indicaron que la creencia en un mundo justo y la ideología política estaban relacionadas con la defensa de la justicia social. Se discuten las implicaciones para formación en terapia de juego y direcciones futuras para investigación.
