Effects of fluoxetine on play dominance in juvenile rats

In a series of three studies, we investigated the influence of a selective serotonin re-uptake inhibitor (fluoxetine) on the rough-and-tumble play of juvenile rats. In Experiment 1, both members of eight pairs of solitary-housed juvenile rats received either vehicle, 2.5, 5, or 10 mg/kg fluoxetine in a counterbalanced within-subject design 20 min before being allowed to play for 5 min periods on four successive test days. The 5 and 10 mg/kg pretreatments significantly reduced incidence of pins during play without affecting dorsal contacts. In Experiment 2, one member of each of 19 established play pairs received 5 mg/kg fluoxetine 20 min before play, while the other member received vehicle. Dominant rats showed no reduction in pins as a result of fluoxetine treatment, but subordinate rats who received fluoxetine exhibited significant reductions in pins. Subsequent dyadic analyses indicated that in pairs where the subordinate animal received fluoxetine, dominant animals maintained their pinning advantage over the 10 days of testing, but in pairs where the dominant animals received fluoxetine, this pinning asymmetry diminished. In Experiment 3, we replicated the above procedure with inexperienced play pairs, to control for the effects of prior social learning. Fluoxetine treatment (5 mg/kg) significantly reduced both pins and dorsal contacts in all treated rats. The results indicate that fluoxetine can reduce the playful pins of juvenile rats, but that prior social learning mediates the strength of these effects. © 1996 Wiley-Liss, Inc.     

The Evolution of Animal Play, Emotions, and Social Morality: On Science, Theology, Spirituality, Personhood, and Love

My essay first takes me into the arena in which science, spirituality, and theology meet. I comment on the enterprise of science and how scientists could well benefit from reciprocal interactions with theologians and religious leaders. Next, I discuss the evolution of social morality and the ways in which various aspects of social play behavior relate to the notion of “behaving fairly.” The contributions of spiritual and religious perspectives are important in our coming to a fuller understanding of the evolution of morality. I go on to discuss animal emotions, the concept of personhood, and how our special relationships with other animals, especially the companions with whom we share our homes, help us to define our place in nature, our humanness. It is when we take the life of another being in the ritual of compassionately euthanizing them (“putting them to sleep”) that who we are in the grand scheme of things comes to the fore. I end with a discussion of the importance of ethological studies, behavioral research in which a serious attempt is made to understand animals in their own worlds, inquiries in which it is asked, “What is it like to be another species?” Species other than nonhuman primates need to be studied. I plead for developing compassionate, heartfelt, and holistic science that allows for interdisciplinary talk about respect, grace, spirituality, religion, love, Earth, and God.     

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.     

The seventh penis: towards effective psychoanalytic work with pre‐surgical transsexuals

The author reflects on his contrasting analytic work with two transsexual patients. He uses three previous psychoanalytic studies (Stoller, Morel and Lemma) to explore whether effective analytic work with the issues driving a person's determined wish for sex reassignment surgery (SRS) is possible. Particular consideration is given to how such work might navigate a path between traumatizing and pathologizing the patient on the one hand and avoiding important analytic material out of fear of so doing on the other. The author proceeds to ask whether it is possible to tell in advance, with any degree of reliability, who is and who is not likely to benefit from surgery. He considers certain diagnostic issues in relation to these questions. Illustrations are given of how, in practice, countertransference anxieties about psychopathologizing transsexual patients can contribute to significant difficulties in working clinically with them. It is argued that the understanding and containment of such anxieties could eventually lead to more effective analytic work, and that such work might be further facilitated by considering the contribution of mind‐body dissociation to transsexualism.     

La traviata and Oedipus

This paper explores the oedipal themes of Verdi's La Traviata, and proposes that it is his masterly treatment of their complexity which accounts for the psychological power of the opera. It is suggested that a particular quality of this opera lies in its ordinariness: no gross psychopathology is displayed, and yet it is mesmerizing. The claims of the eminent musicologist Joseph Kerman are explored that, in opera, music trumps words when there is a conflict between the apparent meanings of the libretto and the feel of the music, with special reference to the famous duet between Violetta (the ‘fallen woman’ – the traviata) – and her lover's father, Giorgio Germont, in which his harsh condemnation of her as conveyed by the libretto text seems to be softened, indeed quite altered, by the music. Other contradictions between the apparently explicit meaning of the text and the implicit sense of the music are also examined. These conflicts are illuminated by John Steiner's theory of two versions of the Oedipus situation, one paranoid–schizoid and the other depressive, which are contrasted with Grunberger's Oedipal views.
