The role of dopamine signaling in prairie vole Peer Relationships.
Hormones and behavior, 2020Co-Authors: Nicole S. Lee, Annaliese K. BeeryAbstract:Abstract Dopamine signaling mediates the formation of some types of social Relationships, including reproductive pair bonds in the socially monogamous prairie vole (Microtus ochrogaster). In addition to these pair bonds with mates, prairie voles demonstrate selective preferences for familiar same-sex Peers. The dependence of Peer Relationships on dopamine signaling has not been tested, and the mechanisms supporting these Relationships may differ from those underlying pair bonds. We examined the effects of pharmacological manipulations of dopamine signaling on Peer partner preference and socially conditioned place preference in female prairie voles. Haloperidol blockade of dopamine receptors at multiple doses did not alter selective preferences for familiar same-sex partners, suggesting that dopamine neurotransmission is not necessary for the formation of prairie vole Peer Relationships, unlike mate Relationships. Dopamine receptor agonist apomorphine facilitated Peer partner preferences under conditions normally insufficient for partner preference formation; however, in the absence of effects from blockade, it is difficult to distinguish between a role for dopamine in partner preference formation and the generally rewarding properties of a dopamine agonist. Prairie voles exhibited socially conditioned place preferences for new but not long-term same-sex Peers, and these preferences were not blocked by haloperidol. These results suggest that prairie vole Peer Relationships are less dependent on dopamine signaling than pair bonds, while still being rewarding. The data support distinct roles of dopamine and motivation in prairie vole Peer Relationships relative to mate Relationships, suggesting that reproductive bonds are mediated differently from non-reproductive ones.

Social reward plays different roles in mate and Peer Relationships in prairie voles
2018Co-Authors: Nicole S. Lee, Sarah A. Lopez, Annaliese K. BeeryAbstract:Abstract of poster PS2.0050 presented July 2018 at International Congress of Neuroendocrinology. Toronto, Canada. Prairie voles (Microtus ochrogaster) are widely studied for their reproductive pair-bonds, but individuals also demonstrate selective preferences for familiar same-sex Peers. The mechanisms underlying pair-bonds in this species may differ from those underlying Peer Relationships, as reproductive partnerships and parental behaviors are highly motivated. We examined the role of reward and motivation in prairie vole Peer Relationships compared to prairie vole mate Relationships through pharmacological manipulations of dopamine signaling as well as operant conditioning. Blockade of dopamine receptors with haloperidol did not alter selective preferences for familiar same-sex partners, suggesting that dopamine neurotransmission is not necessary for the formation of prairie vole Peer Relationships, unlike mate Relationships. Voles were trained to press a lever to gain access to different types of social stimuli. Female voles pressed at higher rates to gain access to a mate than to a familiar same-sex Peer. Once in the social chamber, females huddled significantly more with familiar mates or Peers than with opposite- or same-sex strangers. These data support distinct roles of dopamine and motivation in Peer Relationships relative to pair-bonds: Although they are necessary to form and maintain pair-bonds, they are not necessary for Peer Relationships. The fact that a reproductive bond is mediated differently from a non-reproductive one suggests that Peer Relationships need to be further investigated in addition to pair-bonds to fully elucidate mechanisms of social behavior.

Peer Relationships in physical activity contexts a road less traveled in youth sport and exercise psychology research
Psychology of Sport and Exercise, 2003Co-Authors: Alan L SmithAbstract:Background and Purpose. While it is well established that social agents contribute to the quality of youth physical activity experiences, relatively little research has specifically explored Peer Relationships in physical activity settings. Rather, the bulk of research on social agents has focused on teachers, coaches, and parents. The purpose of this paper is to provide justification for pursuing youth Peer Relationships research and present conceptual and methodological issues of relevance to such efforts. Methods. The existing literature base on Peer Relationships in physical activity contexts is overviewed, emphasizing the contribution of Peers to self-perceptions, moral attitudes and behaviors, affect, and motivation. Results and Conclusions.Promising future research directions are forwarded, focusing on (a) the possible contribution of Peer Relationships research to understanding self-presentational processes and developmental transitions, (b) the importance of examining the interaction of Peer Relationships and other social Relationships in the physical activity context, and (c) the value of using the physical activity setting to promote quality Peer Relationships. 2002 Elsevier Science Ltd.

perceptions of Peer Relationships and physical activity participation in early adolescence
Journal of Sport & Exercise Psychology, 1999Co-Authors: Alan L SmithAbstract:This study tested a model describing the Relationships among perceptions of Peer Relationships, physical self-worth, affective responses toward physical activity, and physical activity motivation. The model was grounded in Harter’s (1978,1981a, 1986,1987) theoretical perspective, proposing that perceptions of Peer Relationships (i.e., friendship, Peer acceptance) would predict physical activity motivation via affect and physical self-worth. Adolescents (N = 418, ages 12–15 years) completed a battery of questionnaires that assessed the study variables. Results of structural equation modeling analyses supported the overall model and most of the hypothesized direct and indirect Relationships among variables for both female and male samples. Examination of alternative models suggested that some expected Relationships might have been suppressed by a high correlation between the friendship and Peer-acceptance constructs. However, alternative models also showed that these constructs independently contribute to p...

social behavior and Peer Relationships of victims bully victims and bullies in kindergarten
Journal of Child Psychology and Psychiatry, 2006Co-Authors: Sonja Perren, Francoise D AlsakerAbstract:Background: Although the prevalence of bully/victim problems in school-age children and adolescents has been investigated in many countries, only a few studies have been carried out among younger children. This study examines social behaviors and Peer Relationships of children involved in bully/victim problems in kindergarten. Methods: Three hundred and forty-four five- to seven-year-old children participated. Children were categorized as victims, bully-victims, bullies, and non-involved by means of teacher ratings and Peer nominations. Teachers completed questionnaires on children's social behavior patterns. Peer Relationships were assessed by means of Peer nominations and social cluster mapping. Results: Compared to non-involved children, victims were more submissive, had fewer leadership skills, were more withdrawn, more isolated, less cooperative, less sociable, and frequently had no playmates. As expected, bullies and bully-victims were generally more aggressive than their Peers. In addition, bully-victims were less cooperative, less sociable, and more frequently had no playmates than non-involved children. Bullies were less prosocial, and had more leadership skills than non-involved children. Bullies belonged to larger social clusters and were frequently affiliated with other bullies or bully-victims. Conclusions: We were able to establish distinct behavior patterns for bullies, bully-victims, and victims. Some of these social behaviors may be considered as risk factors for being victimized or becoming a bully. Our findings also emphasize the significance of Peer Relationships in bully/victim problems. On the one hand, victimized children's lack of friends might render them psychologically and socially vulnerable, and thus more prone to becoming easy targets. On the other hand, bullies seemed to be preferred playmates, particularly for other aggressive boys. This affiliation of aggressive children might lead to an increase in bullying behavior. Our understanding of the social and interactional nature of bullying and victimization has practical implications for prevention and intervention against bully/victim problems.

parent support of preschool Peer Relationships in younger siblings of children with autism spectrum disorder
Journal of Autism and Developmental Disorders, 2018Co-Authors: Annette Estes, Amy Rodda, Jeffrey Munson, Tanya St John, Stephen R Dager, Kelly N Botteron, Heather Cody Hazlett, Robert T Schultz, Lonnie Zwaigenbaum, Joseph PivenAbstract:Preschool-aged siblings of children with ASD are at high-risk (HR) for ASD and related challenges, but little is known about their emerging Peer competence and friendships. Parents are the main providers of Peer-relationship opportunities during preschool. Understanding parental challenges supporting early Peer Relationships is needed for optimal Peer competence and friendships in children with ASD. We describe differences in Peer Relationships among three groups of preschool-aged children (15 HR-ASD, 53 HR-NonASD, 40 low-risk, LR), and examine parent support activities at home and arranging community-based Peer activities. Children with ASD demonstrated precursors to poor Peer competence and friendship outcomes. Parents in the HR group showed resilience in many areas, but providing Peer opportunities for preschool-age children with ASD demanded significant adaptations.

beyond social skills supporting Peer Relationships and friendships for school aged children with autism spectrum disorder
Seminars in Speech and Language, 2018Co-Authors: Amy Rodda, Annette EstesAbstract:Social impairments are the sine qua non of autism spectrum disorder (ASD). However, children with ASD are capable of forming reciprocal friendships and many people with ASD have a strong desire for friends. Developing and maintaining friendships is associated with many important outcomes, including improved quality of life, mental health, and academic achievement. Children with ASD often attend groups to improve social skills, but strategies for building and maintaining friendships are not consistently addressed or measured following intervention. In this article, our objective is to build an understanding of Peer Relationships and friendships in school-aged children with ASD and how to best support them. In this article, we describe characteristics of Peer Relationships and friendships for children with ASD. We discuss current research findings on intervention to improve social skills, Peer Relationships, and friendships in school-aged children with ASD. Finally, we give suggestions for clinical practice and future research.
