Project description:The British Children's Play Survey was conducted in April 2020 with a nationally representative sample of 1919 parents/caregivers with a child aged 5-11 years. Respondents completed a range of measures focused on children's play, independent mobility and adult tolerance of and attitudes towards risk in play. The results show that, averaged across the year, children play for around 3 h per day, with around half of children's play happening outdoors. Away from home, the most common places for children to play are playgrounds and green spaces. The most adventurous places for play were green spaces and indoor play centres. A significant difference was found between the age that children were reported to be allowed out alone (10.74 years; SD = 2.20 years) and the age that their parents/caregivers reported they had been allowed out alone (8.91 years; SD = 2.31 years). A range of socio-demographic factors were associated with children's play. There was little evidence that geographical location predicted children's play, but it was more important for independent mobility. Further, when parents/caregivers had more positive attitudes around children's risk-taking in play, children spent more time playing and were allowed to be out of the house independently at a younger age.

Project description:BackgroundThere is increasing recognition of the importance of children's play from a public health perspective, given the links between play and children's physical and mental health. The present research aimed to develop and evaluate a new parent-report questionnaire that measures the time children spend playing across a range of places and includes a supplement to evaluate how adventurously children play.MethodsThe questionnaire was developed with input from a diverse group of parents and experts in children's play. It was designed to yield a range of metrics including time spent playing per year, time spent playing outside, time spent playing in nature and level of adventurous play. The reliability of the questionnaire was then evaluated with 245 parents (149 mothers, 96 fathers) of 154 children aged 5-11 years. All participants completed the measure at time 1. At time 2, an average of 20 days later, 184 parents (111 mothers and 73 fathers) of 99 children completed the measure again.ResultsCross-informant agreement, evaluated using Concordance Correlation Coefficients (CCCs), ranged from 0.36 to 0.51. These fall in the poor to moderate range and are largely comparable to cross-informant agreement on other measures. Test-retest reliability for mothers was good (range 0.67-0.76) for time spent playing metrics. For fathers, test-retest reliability was lower (range 0.39-0.63). For both parents the average level of adventurous play variable had relatively poor test retest reliability (mothers = 0.49, fathers = 0.42). This variable also showed a significant increase from time 1 to time 2. This instability over time may be due to the timing of the research in relation to the Covid-19 lockdown and associated shifts in risk perception.ConclusionsThe measure will be of value in future research focusing on the public health benefits and correlates of children's play as well as researchers interested in children's outdoor play and play in nature specifically. The development of the measure in collaboration with parents and experts in children's play is a significant strength. It will be of value for future research to further validate the measure against play diaries or activity monitors.

Project description:We apply a new quantitative method for investigating how children's exploration changes across age in order to gain insight into how exploration unfolds over the course of a human life from a life-history perspective. In this study, different facets of exploratory play were quantified using a novel touchscreen environment across a large sample and wide age range of children in the USA (n = 105, ages = 1 year and 10 months to 12 years and 2 months). In contrast with previous theories that have suggested humans transition from more exploratory to less throughout maturation, we see children transition from less broadly exploratory as toddlers to more efficient and broad as adolescents. Our data cast doubt on the picture of human life history as involving a linear transition from more curious in early childhood to less curious with age. Instead, exploration appears to become more elaborate throughout human childhood. This article is part of the theme issue 'Life history and learning: how childhood, caregiving and old age shape cognition and culture in humans and other animals'.

Project description:Sex-dependent effects of mismatched prenatal-postnatal maternal conditions are predicted by combining two evolutionary hypotheses: that foetal conditions provide a forecast of likely postnatal environments (Predictive Adaptive Response), and that the female foetus is better adapted than the male to maternal adversity (Trivers-Willard hypothesis). Animal studies have implicated glucocorticoid mechanisms modifiable by effects of postnatal tactile stimulation on glucocorticoid receptor gene expression. In this study we examined behavioural predictions in humans based on these evolutionary and epigenetic models. Mothers in a general population cohort provided self-reported anxiety scores at 20 weeks pregnancy, and at 9 weeks, 14 months and 3.5 years postpartum, and frequency of infant stroking at 9 weeks. Mothers and teachers reported child symptoms at 7 years. SEM models with maximum-likelihood estimates made use of data from 887 participants. There was a three-way interaction between prenatal and postnatal anxiety and maternal stroking in the prediction of irritability, seen only in girls. This arose because lower maternal stroking was associated with higher irritability, only in the mismatched, low-high and high-low maternal anxiety groups. We provide evidence that mechanisms likely to have evolved well before the emergence of humans, contribute to the development of children's emotionality and risk for depression.

Project description:The United Nations Convention on the Rights of the Child has substantiated play for play's sake, thus focusing on the doing or being of play rather than any potentially desired outcomes. Examining this type of play from the perspective of the child acknowledges children as meaning-makers. A scoping review was conducted to expose and map the extent of the evidence available in the emerging and diverse field of children's experiences of play in digital spaces. Specifically, the literature was examined with regards to relevance to children's everyday lives, the personal and ecological relevance, and the methods used. A systematic search of the literature over the past fifteen years found thirty-one articles appropriate for inclusion. The analysis of the literature revealed that the articles formed four categories of how play in digital spaces was approached: 'Videogames, behaviours, and societal norms', 'Videogames for its own sake', 'Videogames for learning', and 'Active Videogames for health promotion'. This scoping review has identified a lack of articles focusing on children's experiences of play in a digital space, and these perspectives are essential for parents, professionals, game designers, and policymakers alike to contribute to an enhanced understanding of the role of play in digital spaces.

Project description:Learning to use, make, and modify tools is key to our species' success. Researchers have hypothesized that play with objects may have a foundational role in the ontogeny of tool use and, over evolutionary timescales, in cumulative technological innovation. Yet, there are few systematic studies investigating children's interactions with objects outside the post-industrialized West. Here, we survey the ethnohistorical record to uncover cross-cultural trends regarding hunter-gatherer children's use of objects during play and instrumental activities. Our dataset, consisting of 434 observations of children's toys and tools from 54 hunter-gatherer societies, reveals several salient trends: Most objects in our dataset are used in play. Children readily manufacture their own toys, such as dolls and shelters. Most of the objects that children interact with are constructed from multiple materials. Most of the objects in our dataset are full-sized or miniature versions of adult tools, reflecting learning for adult roles. Children also engage with objects related to child culture, primarily during play. Taken together, our findings show that hunter-gatherer children grow up playing, making, and learning with objects.

Project description:ObjectiveIndividuals from low-income countries often migrate abroad for employment. The association between such migration and investment in education as well as other societal and familial outcomes has previously been examined. However, we have a limited understanding of the association between migration and children's nutrition. We aim to determine the extent to which migration of household members influences children's diet in a semi-urban region of Nepal.ResultsIn our study setting, children in households with a migrant had higher dietary diversity scores, 0.69 on average, than their counterparts in households without a migrant. These children were approximately 43% points more likely to meet a minimum requirement for dietary diversity. These differences originated primarily from higher consumption of meat (41% points) and eggs (20% points). Approximately 37 percent of children in the sample consumed processed food during the 24 h preceding the survey. However, we found no evidence that migration was associated with the consumption of processed foods or with reduced frequency of breastfeeding. Our finding that migration is associated with higher consumption of meat and eggs is particularly encouraging, given that the protein deficiency in Nepal is estimated to be nearly 43 percent.

Project description:Exploration and play are considered to be crucial behaviors during mammalian development. Even though the relationship between glucocorticoids and exploratory behavior, stress, and anxiety is well described in the literature, very little is known about their role in play behavior in non-rodents. Likewise, the functional role of the "social hormone" oxytocin in exploration, play, stress, and anxiety is still unknown. The present work addresses this literature gap by studying plasma hormone profiles for cortisol (CORT) and oxytocin (OT) of domestic dogs exposed to a novel arena containing two unfamiliar trainers who did not interact with the dogs. We provide evidence suggesting a functional relationship between hormonal measures of cortisol and oxytocin and adaptive behavior (play-soliciting and exploration) in freely behaving domestic dogs. We have taken into account several possible factors in our analyses and interpretations, from the nature and quality of the measurements to demographic factors to statistical robustness. Our results indicate that reduced CORT levels are associated with increments of both play-soliciting behavior frequency and exploratory behavior duration. Furthermore, taken together, our data and our simulations suggest a relationship between OT and the enactment of play-soliciting behaviors by freely behaving domestic dogs that must be further investigated. Future studies should consider naturalistic structured and semi-structured experimental approaches linking behavior with (neuro) physiological measures, taking into account demographic factors such as age and relevant interphase factors such as the sex of the dog; and socio-historic factors such as the playfulness of the dog, history of interaction with young humans, among others, to take full account of interaction between humans and animals in comparative studies (Parada and Rossi, 2018).

Project description:Athlete-driven informal sport play represents an important context for athlete development. However, in contrast to coach-driven organized sport, little is known about the interpersonal processes driving development in this context. The present study was an exploratory descriptive analysis of the interactive peer behaviors occurring in an informal sport play setting and their relationship to athlete psychological characteristics. Thirty young athletes (<25 years old, Mage = 19.84) participating in informal mixed-age volleyball, soccer, and basketball sessions at a community recreation center were observed and their interactive behavior coded. Participants also completed questionnaire measures of psychological characteristics (competence, confidence, character). Descriptive analyses examined the interaction patterns of young athletes in these contexts. Multiple regression analyses were then conducted to examine the relationships between peer interactive behavior and athlete psychological characteristics. Results point to the social nature of participation in informal sport play contexts and the critical relationship between athlete competence and peer interaction tendencies. This study presents an initial exploration of peer interactive behavior in informal, mixed-age sport play contexts, but continued future research is needed to better understand the developmental processes and implications of participation in these important contexts.

Project description:Debate regarding the best way to test and measure eyewitness memory has dominated the eyewitness literature for more than 30 years. We argue that resolution of this debate requires the development and application of appropriate measurement models. In this study we developed models of simultaneous and sequential lineup presentations and used these to compare these procedures in terms of underlying discriminability and response bias, thereby testing a key prediction of diagnostic feature detection theory, that underlying discriminability should be greater for simultaneous than for stopping-rule sequential lineups. We fit the models to the corpus of studies originally described by Palmer and Brewer (2012, Law and Human Behavior, 36(3), 247-255), to data from a new experiment and to eight recent studies comparing simultaneous and sequential lineups. We found that although responses tended to be more conservative for sequential lineups there was little or no difference in underlying discriminability between the two procedures. We discuss the implications of these results for the diagnostic feature detection theory and other kinds of sequential lineups used in current jurisdictions.
