Loneliness and peer relations in childhood

Although loneliness is a normative experience, there is reason to be concerned about children who are chronically lonely in school. Research indicates that children have a fundamental understanding of what it means to be lonely, and that loneliness can be reliably measured in children. Most of the research on loneliness in children has focused on the contributions of children's peer relations to their feelings of well-being at school. Loneliness in children is influenced by how well accepted they are by peers, whether they are overtly victimized, whether they have friends, and the durability and quality of their best friendships. Findings from this emerging area of research provide a differentiated picture of how children's peer experiences come to influence their emotional well-being.     

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.

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.     

Does controlling for comorbidity matter? DSM‐oriented scales and violent offending in chicago youth

Mental health problems have long been linked to antisocial behaviors. Despite an impressive body of literature demonstrating this relationship and claims that comorbidity matters, few studies examine comorbidity using multiple distinct mental health indicators, with most studies instead adopting single or composite mental health measures. This study tested separate and comorbid effects of five DSM‐oriented mental health issues on self‐reported violence using a community‐based sample of Chicago youths from the Project on Human Development in Chicago Neighborhoods. Moreover, it utilized both primary caregiver and youth self‐reports of psychopathology across four developmental stages of childhood and adolescence. When examined separately, the results indicated affective/depressive, anxiety, attention deficit hyperactivity, and oppositional defiant/antisocial personality problems independently predicted violence. When considering comorbidity, however, only oppositional defiant and antisocial personality problems significantly predicted violence at any stage, regardless of informant type. Implications for future studies and policy are discussed. Aggr. Behav. 36:141–157, 2010. © 2010 Wiley‐Liss, Inc.     

The Montreal Protocol for Identification of Amusia

The Montreal Battery for the Evaluation of Amusia (MBEA; Peretz, Champod, & Hyde Annals of the New York Academy of Sciences, 999, 58–75, 2003) is an empirically grounded quantitative tool that is widely used to identify individuals with congenital amusia. The use of such a standardized measure ensures that the individuals tested will conform to a specific neuropsychological profile, allowing for comparisons across studies and research groups. Recently, a number of researchers have published credible critiques of the usefulness of the MBEA as a diagnostic tool for amusia. Here we argue that the MBEA and its online counterpart, the AMUSIA tests (Peretz et al. Music Perception, 25, 331–343, 2008), should be considered steps in a screening process for amusia, rather than standalone diagnostic tools. The goal of this article is to present, in detailed and easily replicable format, the full protocol through which congenital amusics should be identified. In providing information that has often gone unreported in published articles, we aim to clarify the strengths and limitations of the MBEA and to make recommendations for its continued use by the research community as part of the Montreal Protocol for Identification of Amusia.     

A new typology of fathering: defining and associated variables

Our goal was to identify different types of parenting based on self‐report measures of fathers' involvement and parental attitudes. The present investigation studied 468 two‐parent, French Canadian families with at least one child between 0 and 6 years of age, living in a disadvantaged environment. The study, conducted on a sample of fathers, revealed the presence of the three basic types of parenting identified by Baumrind (authoritarian, authoritative and permissive), and also of a new type of parenting (stimulative parenting). The fathers in this latter group provide more emotional support to children and are more stimulating, as is evidenced by the greater psychological presence of children in the father's cognitions and by the fact that they more frequently introduce their children to new activities. These fathers are characterized by more secure social relationships. The father's parental stress level was found to be the most important variable discriminating between different types of fathering. Authoritarian and authoritative fathers are more at risk of maltreating their children because their more favourable attitude towards the use of physical punishment is combined with greater parental stress, less parental involvement of mothers, and a larger number of children in the home. Authoritarian fathers are even more at risk of maltreating their children because of more difficult family socioeconomic conditions, particularly lower levels of maternal education and income.

Atypical Hemispheric Specialization in Intellectual Deficiency

In order to determine the relation between hemispheric specialization for language and intellectual deficiency, two groups of lower-IQ subjects were compared to normal-IQ controls on word-dichotic listening tasks. Two conditions in which stimuli differed by their level of phonological complexity were used. Normal controls showed the expected right-ear advantage in both conditions. Moreover, they showed a greater magnitude of ear difference on the condition requiring higher-order phonological processing. In the mentally deficient group, almost half the subjects exhibited a left-ear advantage and they showed no difference between the two conditions in terms of the magnitude of ear difference. These results point to the presence of atypical hemispheric specialization in mentally deficient subjects.
