The article discusses why depression hurts. It says that affective neuroscience consists of seven primary functions namely seeking, rage, fear, sexual lust, maternal care, separation distress or panic, and play. It states that depression is closely related to sustained overactivity of the panic system resulting to psychological despair if prolonged, and to the despair phase […]

Bonobos, compared to chimpanzees, are highly motivated to play as adults. Therefore, it is interesting to compare the two species at earlier developmental stages to determine how and when these differences arise. We measured and compared some play parameters between the two species including frequency, number of partners (solitary, dyadic, and polyadic play), session length, […]

The primal affects are intrinsic brain value systems that unconditionally and automatically inform animals how they are faring in survival. They serve an essential function in emotional learning. The positive affects index ” comfort zones ” that support survival, while negative affects inform animals of circumstances that may impair survival. Affective feelings come in several […]

Most theories on the function of play have focused on ultimate rather than proximate benefits. Play peaks during juvenility but, in some species, it is present in adulthood as well. In primates, social play and grooming often show a matched pattern because they bring individuals into close contact and favor social cohesion. In Pan, researchers […]

In many mammal species, precocious sexual behaviour is a component of play. A recent model for the evolution of play fighting behaviour in muroid rodents by PELLIS (1993) proposes that social play in those species has its origin in precocious sexual behaviour. Captive juvenile emydid turtles perform precocious sexual behaviour. After reviewing its occurrence, we […]

Posner & Raichle’s (1994) exciting, wonderfully illustrated book describes the past successes and future potential of the relatively noninvasive imaging of the nervous systems of living people. The focus has been on cognitive processes but there is no reason why emotional and motivational systems cannot also be tapped. Although the authors do not formally address […]
4 Purpose: The consensus is that physical activity (PA) and sedentary behavior (SB) are independent behaviors, but past findings suggest that they may be influenced by common underlying factors. To clarify this issue, we examined associations between enjoyment of PA and participation in both PA and SB in a large sample of 4th- to 12th-grade US […]

Infants exhibit visual preferences for gender-typed objects (e.g., dolls, toy vehicles) that parallel the gender-typed play preferences of preschool-aged children, but the developmental stability of individual differences in early emerging gender-typed preferences has not yet been characterized. In the present study, we examined the longitudinal association between infants’ (N= 51) performance on an objectpreference task, […]

Sought to replicate and extend the findings of the 2nd author and W. W. Beatty (see record 1981-29710-001) that lesions of the dorsomedial thalamus (DMT) or the parafascicular area of the thalamus (PFA) reduced the frequency of pinning, believed to be a valid indicator of juvenile play in the rat. Data from 54 juvenile Long-Evans rats indicate […]

The “affective ” and “cognitive ” neuroscience approaches to understanding emotion (AN and CN, respectively) represent potentially synergistic, but as yet unreconciled, theoretical perspectives, which may in part stem from the methods that these distinct perspectives routinely employ one focusing on animal brain emotional systems (AN) and one on diverse human experimental approaches (CN). Here […]

In this article, we introduce the special issue on work/think/play in qualitative and postqualitative inquiry. Our aim for the issue is to open up conversations about what does happen, what can happen, and/or what should happen in the name of qualitative and postqualitative inquiry. We hope that the issue raises methodological questions in qualitative and […]
8 Social interaction (play fighting) was studied in socially housed and individually housed juvenile rat+D606). Pinning (an animal on its back, with the other on top) proved to be a simple measure of play which correlated highly with other measures of playful behavior (solicitive behaviors, following, rough-and-tumble play, and together-time measures). Play behaviors were markedly increased […]

In small-scale societies children have great access to observing adult roles and this is often reflected in their play, however very few empirical studies of work-themed play have been conducted despite substantial implications that this type of play has for social learning. The current study describes the work-themed play patterns of 1 1/2- to 4-year-old […]

(3H)Diprenorphine binding was analyzed autoradiographically in the brains of 33 day old rat pups. A photographic atlas of diprenorphine binding in the coronal plane is provided to highlight the dispersion of opioid receptor systems through the brain. To determine whether brain opioid release may be induced by social interactions, half the animals were sacrificed following […]

In this paper, the intersections of play and learning across the concrete and digital domains in early childhood settings are explored and illustrated. Play is an important component in the early years, expanding children’s opportunities for social interaction and engagement, essential constructs for overall development. The traditional setting for children’s play and learning has undergone […]

It has been recently shown that human adolescents with Attention Deficit/Hyperactivity Disorder (ADHD) have frontal lobe deficits, especially on the right sides of their brains (Castellanos et al., 1996). ADHD is commonly treated with psychostimulants which may have adverse consequences. Hence, less invasive therapies need to be developed. In the present work, we tested the […]

The aim of this study was to thoroughly investigate social play and its modalities among adult bonobos. We evaluated how play intensity varies according to the sex-class combination of the playmates and we also performed an analysis on social locomotor-rotational movements (L-R play) and contact interactions (C play). Rough and gentle play sessions were performed […]
2 play fighting in its most elaborate form involves nonagonistic wrestling between pairmates, where one partner grabs, holds, bites, or otherwise contacts the other. Such play occurs in the absence of the functional consequences associated with serious fighting (e.g., resource acquisition or protection). Typically, the biting, nosing, or grooming contact during play fighting is directed at […]

This paper discusses collaborative research between academics and practitioners to enhance the level of play engagement in nine groups of toddlers in The Netherlands. Researchers and pedagogic counsellors designed a structured experiment to test the effects of four pedagogical strategies: confronting the children with a rearranged activity corner; free play, with the teacher available at […]

This study sought to identify the games played and preferred by children during school recess in the so-called first cycle, breaking that information down by gender and school year. A questionnaire was applied in two basic education schools in northern Portugal. The sample included 317 students from the four years in that stage – 167 […]
