Why Do the Children (Pretend) Play?

Caregiver or Playmate? Fathers' and mothers' brain responses to ball-play with children

Parents and children often engage in joint play-a domain where mothers and fathers are thought to exhibit disparate behaviors and impact child development via distinct mechanisms. However, little is known about the neural substrates of mother-child and father-child play. In this fMRI study, we sampled the brain activation of parents of preschoolers (N = 88) during a novel event-related adaptation of the virtual ball-tossing game "Cyberball." Mothers (N = 40) and fathers (N = 48) played "Cyberball" ostensibly with their own and an unrelated child, who consecutively included, excluded, and reincluded parents. We found that overall, exclusion yielded comparable neural activations in mothers and fathers associated with mentalizing, saliency, and emotion processing. We also observed a parent gender effect in several brain areas. While mothers exhibited increased reward- and attention-related activity during inclusion, fathers displayed increased mentalizing-related activity during exclusion. Furthermore, we tested parents' response to reinclusion, which revealed a selective decrease in reward-related activity. Finally, exploratory analyses showed that parental involvement was positively correlated with parental brain activity within attention- and mentalizing-related areas during inclusion, as opposed to other game phases, and that an anxious parenting style was associated with increased neural sensitivity for game events involving their own child. Overall, our study elucidates the common and distinct neural networks that mothers and fathers engage during play interactions with their children, supporting theories that postulate only a partial differentiation of paternal and maternal parenting systems.

A socially prescribed creative play intervention for new parents: investigating post traumatic stress around birth and changes in postnatal depression and reflective function

BACKGROUND

Parenthood is a key transition period which involve emotional, social and physical adjustments. Social prescribing is a method that connects people to community-based activities, groups, and services to addressing various needs impacting their health and wellbeing. This pilot investigation aimed to assess whether a curated socially prescribed creative play programme would impact upon new parents' social connection, mental health and reflective function through a programme designed to support these changes.

METHODS

This study was part of a 5-week long socially prescribed creative play programme at a family theatre company in the North of England, aimed at providing social capital to families while teaching creative play. In total, 57 parents (M = 30.73, SD = 6.20) completed baseline and post-intervention measures of birth trauma experiences (City Birth Trauma Scale), postnatal depression (Edinburgh Postnatal Depression Scale) reflective function (Reflective Functioning Questionnaire), and qualitative, open-ended questions on social opportunities. Descriptive analyses were completed using t-tests and chi-square tests, while repeated measures ANOVAs were used to answer questions around the main analyses.

RESULTS

The participants experienced a statistically significant reduction in postnatal depression scores following the intervention, but no changes were found in reflective function or birth trauma scores; secondly, birth trauma scores predicted later depression scores as well as reflective functioning uncertainty scores (but not certainty scores). Qualitative analysis found social opportunities were not why parents came but was, after attending, their favourite part of the socially prescribed programme. Those parents reporting on social opportunities were more likely to reference their own needs while non-social activities were associated with their child's needs.

CONCLUSIONS

Socially prescribed creative play programmes for new parents could be a "waiting well" intervention. A longer duration and trauma informed focus would need to be considered in future cohorts.

In praise of folly: flexible goals and human cognition

Humans often pursue idiosyncratic goals that appear remote from functional ends, including information gain. We suggest that this is valuable because goals (even prima facie foolish or unachievable ones) contain structured information that scaffolds thinking and planning. By evaluating hypotheses and plans with respect to their goals, humans can discover new ideas that go beyond prior knowledge and observable evidence. These hypotheses and plans can be transmitted independently of their original motivations, adapted across generations, and serve as an engine of cultural evolution. Here, we review recent empirical and computational research underlying goal generation and planning and discuss the ways that the flexibility of our motivational system supports cognitive gains for both individuals and societies.

My favourite part was learning different ways to play: qualitatively evaluating a socially prescribed creative play programme

OBJECTIVES

Social prescription is classically thought of as an initiative for older people. This qualitative study aimed to evaluate the first socially prescribed creative play programme for families of 0-3-year-old children in the UK, examining the experience of the parents throughout the stages of the programme.

STUDY DESIGN

The evaluation ran longitudinally over 5 weeks using interviews, field notes, and questionnaire data.

METHODS

The evaluation was carried out over 5 weeks in 2022 using intervention leaders' and researcher's field notes, nine parent semi-structured interviews, and 17 parent questionnaires on their experiences. Data were analysed using inductive interpretive thematic analysis.

RESULTS

After analysis of the corpus of data, three themes that interacted with each other were identified: Support Systems that Parents Trust, Calming in Chaos, and Practical Parenting Utility. Parents said that they were more likely to sign up for the programme when they trusted the recommender and the organisation running the programme. They found the socially prescribed group more relaxed and calm than other groups, and their daily lives. The knowledge about health behaviours and modelling of play were the main take-home skills reported.

CONCLUSION

In order for parents to be receptive to practical parenting knowledge the SP aimed to foster, parents must first establish trust in a calming atmosphere. Social links and child development were the key factors parents identified linking to well-being. This research could inform public health policy on social prescription for families.

Preschoolers negatively evaluate conventional norm violations in pretend play

A growing body of research demonstrates that children's pretend play is largely influenced by their understanding of reality. The current work took a novel approach to testing children's understanding of pretense by investigating whether children apply and uphold their knowledge of conventional norms in pretend play. In this study, 3- to 5-year-old children (N = 200) were introduced to a series of pretend play scenarios (e.g., pretending to eat breakfast) in which a puppet pretended to follow a norm (e.g., pretended to eat cereal for breakfast) or violate a norm (e.g., pretended to eat a hamburger for breakfast). These pretend play scenarios were presented as either fantastical or realistic in nature. Consistent with our hypotheses, children evaluated pretend norm violation more negatively than pretend norm adherence and reported liking norm violators less than norm followers. Contrary to our hypothesis, the manipulation of play context (fantastical vs. realistic) did not affect children's evaluations. That is, children were just as negative about pretend norm violations (relative to pretend norm adherence) in fantastical pretend play scenarios as they were in realistic pretend play scenarios. Furthermore, individual differences in children's fantasy orientation did not predict their evaluations. This study is the first to establish that children maintain their real-world understanding of conventional norms in pretend play, providing further evidence that children's pretense is largely realistic in nature.

Action video games normalise the phonemic awareness in pre-readers at risk for developmental dyslexia

Action video-games (AVGs) could improve reading efficiency, enhancing not only visual attention but also phonological processing. Here we tested the AVG effects upon three consolidated language-based predictors of reading development in a sample of 79 pre-readers at-risk and 41 non-at-risk for developmental dyslexia. At-risk children were impaired in either phonemic awareness (i.e., phoneme discrimination task), phonological working memory (i.e., pseudoword repetition task) or rapid automatized naming (i.e., RAN of colours task). At-risk children were assigned to different groups by using an unequal allocation randomization: (1) AVG (n = 43), (2) Serious Non-Action Video Game (n = 11), (3) treatment-as-usual (i.e., speech therapy, n = 11), and (4) waiting list (n = 14). Pre- and post-training comparisons show that only phonemic awareness has a significantly higher improvement in the AVG group compared to the waiting list, the non-AVG, and the treatment-as-usual groups, as well as the combined active groups (n = 22). This cross-modal plastic change: (i) leads to a recovery in phonemic awareness when compared to the not-at-risk pre-readers; (ii) is present in more than 80% of AVG at-risk pre-readers, and; (iii) is maintained at a 6-months follow-up. The present findings indicate that this specific multisensory attentional training positively affects how phonemic awareness develops in pre-readers at risk for developmental dyslexia, paving the way for innovative prevention programs.

The significance of parental mentalizing for four-year-old children's solitary pretend play

BACKGROUND

Pretend play is a signature behavior of early childhood and is considered to reflect the child's emerging symbolic function, enabling the interpretation of social signals, language development, and emotion understanding. While theory links parental mentalizing with children's pretend play, only a few studies have investigated this association. These studies are limited to infancy and early toddlerhood, and child pretend play is assessed during play with an adult (social play). Based on the assumption that child solitary pretend play reflects the child's 'baseline' pretend play ability, in this study, we investigated children's pretend play at its peak, i.e., during the preschool age, without the facilitation of another player. The overall objective was to investigate if parental mentalizing increases pretend play complexity in children.

METHODS

The sample consisted 99 Danish mothers and their 4-year-old children. Employing a cross-sectional design, we hypothesized that parental mental state language, as an indicator of 'online' mentalizing during interaction with the child, is a mechanism through which 'offline' mentalizing, measured as parental reflective functioning, is associated with child solitary pretend play. Child pretend play complexity was observed and coded with an adapted version of the 12-Step Play Scale. Maternal offline mentalizing was assessed with the Parental Reflective Functioning Questionnaire, and maternal online mentalizing was assessed by coding the mothers' mental state language during interaction with the child using a modified version of the mind-mindedness coding scheme.

RESULTS

While there was no direct effect of maternal offline reflective functioning on child pretend play, online mental state language mediated the link between offline maternal reflective functioning and child pretend play.

CONCLUSIONS

These results provide support for the theoretically assumed link between parental mentalizing and children's capacity for pretend play. Furthermore, our study contributes to the literature on parental mentalization, suggesting that parental mentalizing facilitates child development only if the parent can translate this ability into 'mentalizing in action'.

Not Playing by the Rules: Exploratory Play, Rational Action, and Efficient Search

Recent studies suggest children's exploratory play is consistent with formal accounts of rational learning. Here we focus on the tension between this view and a nearly ubiquitous feature of human play: In play, people subvert normal utility functions, incurring seemingly unnecessary costs to achieve arbitrary rewards. We show that four-and-five-year-old children not only infer playful behavior from observed violations of rational action (Experiment 1), but themselves take on unnecessary costs during both retrieval (Experiment 2) and search (Experiments 3A-B) tasks, despite acting efficiently in non-playful, instrumental contexts. We discuss the value of such apparently utility-violating behavior and why it might serve learning in the long run.

Pandemic play moderates the relation between caregiver stress and child emotional distress in contexts of economic adversity

It is well-established that caregiver stress is linked to increased emotional distress among children, and recent evidence highlights similar associations between caregiver and child emotional well-being during the coronavirus (COVID-19) pandemic. Examining protective factors and coping mechanisms that are associated with resiliency in the face of pandemic-related stress can highlight potential strategies that may help children adapt to other unexpected hardships outside of a global pandemic. Previous research found that playing about the pandemic moderated an association between caregiver stress and children's emotional distress. However, few studies have explored "pandemic play" among children from low-income households, where pandemic-related stressors were often exacerbated. In the present study, 72 caregivers of Head Start preschoolers between 3 and 6  years of age were surveyed between late 2020 and early 2021. Results revealed that 32% of children engaged in pandemic play frequently. Caregiver stress was positively associated with child emotional distress, but only among children who did not engage in pandemic play frequently. These findings support the idea that child-directed play may be a developmentally appropriate and accessible coping mechanism to reduce the emotional burden of stressful events on children, regardless of economic context.

Pretend play as abstraction: Implications for early development and beyond

Humans are the only species that engages in sustained, complex pretend play. As pretend play is practically ubiquitous across cultures, it might support or afford a context for developmental advances during the juvenile period that have implications for functioning in adulthood. Early in development, learning to separate our thoughts from reality is practiced in pretend play and is associated with changes not just in cognition, but in emotional and social domains as well. Specifically, pretend play affords opportunities to engage in abstractions that could support abilities such as perspective-taking, emotion recognition and regulation, and cooperation and negotiation in childhood. In turn, the abstraction skills promoted by early pretend play might underlie creativity, innovation, and our capacity to feel empathy and moral obligation to others in later childhood and adulthood. In fact, because pretend play affords sharing our abstractions with others, it might be an early context for behaviors that ultimately promote the shared abstractions of human culture itself.

Mommy, Can I Play Outside? How Urban Design Influences Parental Attitudes on Play

Although play results in physical, social, and cognitive benefits, there is a consensus that children's opportunities to play have been reduced, particularly for those who live in urban environments. What are the barriers to play, and how can we mitigate them? This review examines a critical factor in play opportunities: parents as the decision-makers with regard to children's play. Using perspectives from psychology, urban design, and cognitive science, we analyze the relationships between the design of built environments, parental attitudes and beliefs, and parental decisions on allowing children to play. For example, can a new implementation of children-centered urban design change parents' skeptical attitude toward play? By drawing from global studies, we chart (1) the three key beliefs of parents regarding play and built environments: play should benefit learning, be safe, and match the child's competence and (2) the design principles that can foster these beliefs: learning, social, and progressive challenge designs. By making the link between parents, urban design, and play explicit, this paper aims to inform parents, educators, policymakers, urban planners, and architects on the evidence-based measures for creating and increasing opportunities to play.

Play fighting and the development of the social brain: The rat's tale

The benefits gained by young animals engaging in play fighting have been a subject of conjecture for over a hundred years. Progress in understanding the behavioral development of play fighting and the underlying neurobiology of laboratory rats has produced a coherent model that sheds light on this matter. Depriving rats of typical peer-peer play experience during the juvenile period leads to adults with socio-cognitive deficiencies and these are correlated with physiological and anatomical changes to the neurons of the prefrontal cortex, especially the medial prefrontal cortex. Detailed analysis of juvenile peer play has shown that using the abilities needed to ensure that play fighting is reciprocal is critical for attaining these benefits. Therefore, unlike that which was posited by many earlier hypotheses, play fighting does not train specific motor actions, but rather, improves a skill set that can be applied in many different social and non-social contexts. There are still gaps in the rat model that need to be understood, but the model is well-enough developed to provide a framework for broader comparative studies of mammals from diverse lineages that engage in play fighting.

Autistic children who create imaginary companions: Evidence of social benefits

LAY ABSTRACT

Research on neurotypical children with imaginary friends has found that those with imaginary friends have better social skills and are more able to think about how other people's minds work compared to children without imaginary friends. Research shows that some autistic children also create imaginary friends. This article is the first to look at whether or not autistic children with imaginary friends have stronger social skills and an improved ability to think about others' minds than those without imaginary friends. We asked parents to report about their children aged 5 to 12. Finding almost half reported their child had an imaginary friend, a much larger number than previous research with younger children. Our findings also suggested that autistic children with imaginary friends were better able to understand others' minds and had stronger social skills than their peers without imaginary friends. The children's language ability did not influence this. The findings of this study add to the evidence that with respect to the creation imaginary friends and their potential benefits, the play profiles of autistic children are similar to the general population. It also provides more evidence that the understanding of others' minds is not all or nothing in autism and gives reason for researchers to investigate whether the causes of these differences are the same or different for autistic children.

Why doesn't executive function training improve academic achievement? Rethinking individual differences, relevance, and engagement from a contextual framework

Performance on lab assessments of executive functions predicts academic achievement and other positive life outcomes. A primary goal of research on executive functions has been to design interventions that improve outcomes like academic achievement by improving executive functions. These interventions typically involve extensive practice on abstract lab-based tasks and lead to improvements on these practiced tasks. However, interventions rarely improve performance on non-practiced tasks and rarely benefit outcomes like academic achievement. Contemporary frameworks of executive function development suggest that executive functions develop and are engaged within personal, social, historical, and cultural contexts. Abstract lab-based tasks do not well-capture the real-world contexts that require executive functions and should not be expected to provide generalized benefits outside of the lab. We propose a perspective for understanding individual differences in performance on executive function assessments that focuses on contextual influences on executive functions. We extend this contextual approach to training executive function engagement, rather than training executive functions directly. First, interventions should incorporate task content that is contextually relevant to the targeted outcome. Second, interventions should encourage engaging executive functions through reinforcement and contextual relevance, which may better translate to real-world outcomes than training executive functions directly. While such individualized executive functions interventions do not address systemic factors that greatly impact outcomes like academic achievement, given the extensive resources devoted to improving executive functions, we hypothesize that interventions designed to encourage children's engagement of executive functions hold more promise for impacting real-world outcomes than interventions designed to improve executive function capacities.

Developing Children's Creativity and Social-Emotional Competencies through Play: Summary of Twenty Years of Findings of the Evidence-Based Interventions "Game Program"

This work presents the results of four cooperative-creative game programs (Game Programs). In all four studies, experimental designs with repeated pretest-posttest measures and control groups were used. Validation samples ranged from 86 to 178 participants, randomly assigning participants to the experimental and control conditions. Before and after each program, a battery of assessment instruments was applied to measure the variables under study. The intervention consists of conducting a weekly game session during the school year. The results of the posttest covariance analyses confirmed a significant impact: (1) in social development, by increasing various positive social behaviors and decreasing many negative social behaviors; by increasing assertive cognitive strategies and prosocial resolution of interpersonal problems; and by enhancing relationships and positive communication among group members; (2) in emotional development, by improving self-concept, peer image, and emotional stability; and (3) in cognitive development, by increasing verbal intelligence, verbal and graphic-figurative creativity, as well as creative personality behaviors and traits. This work provides empirical evidence of the relevance of cooperative-creative play in child development.

Walking in Her Shoes: Pretending to Be a Female Role Model Increases Young Girls' Persistence in Science

Pretend play is a ubiquitous learning tool in early childhood, enabling children to explore possibilities outside of their current reality. Here, we demonstrate how pretend play can be leveraged to empower girls in scientific domains. American children ages 4 to 7 years (N = 240) played a challenging science activity in one of three conditions. Children in the exposure condition heard about a successful gender-matched scientist, children in the roleplay condition pretended to be that scientist, and children in the baseline condition did not receive information about the scientist. Girls in the roleplay condition, but not in the exposure condition, persisted longer in the science activity than girls in the baseline condition. Pretending to be the scientist equated girls' persistence to that of boys. These findings suggest that pretend play of role models motivates young girls in science and may help reduce gender gaps from their roots.

Pretensive Shared Reality: From Childhood Pretense to Adult Imaginative Play

Imaginative pretend play is often thought of as the domain of young children, yet adults regularly engage in elaborated, fantastical, social-mediated pretend play. We describe imaginative play in adults via the term “pretensive shared reality;” Shared Pretensive Reality describes the ability of a group of individuals to employ a range of higher-order cognitive functions to explicitly and implicitly share representations of a bounded fictional reality in predictable and coherent ways, such that this constructed reality may be explored and invented/embellished with shared intentionality in an ad hoc manner. Pretensive Shared Reality facilitates multiple individual and social outcomes, including generating personal and group-level enjoyment or mirth, the creation or maintenance of social groups, or the safe exploration of individual self-concepts (such as alternative expression of a players sexual or gender identity). Importantly, Pretensive Shared Reality (both within the specific context of table-top role-playing games, and other instances) are primarily co-operative and co-creative. We draw on multiple examples, and focus on Table-Top Role Playing games (TTRPG) – and specifically, the most popular and enduring table-top role-playing games, Dungeons & Dragons (D&D) – as a primary example of such play. Our conception of “pretensive shared reality” links the widespread existence and forms of adult imaginative play to childhood pretense, places it within a developmental and evolutionary context, and argues that pretensive shared realities – which underpin many forms of imaginative culture – are an important topic of study unto themselves, and may be utilized to provide methodological insight into a variety of psychological domains.

“Complete the Drawing!”: The Relationship between Imagination and Executive Functions in Children

An indirect connection between executive functioning and imagination was revealed earlier in the study of pretend play. This study aimed to explore the relationship between imagination and executive functions in children. Two-hundred-six typically developing children aged 6–7 years were assessed with main executive functions (working memory, inhibition, and cognitive flexibility) and nonverbal imagination (imagination flexibility, image detailedness, image creation strategy, and originality coefficient). Three General Linear Models were built to examine the relationship between executive functions and imagination among children, controlling for age and gender. The obtained results indicate a positive correlation between such characteristics of imagination as originality and flexibility with visual-spatial working memory and cognitive flexibility. However, the data also show that the children who creatively approach the production of new images often experience difficulties with inhibition tasks. The results are interpreted in the context of the educational system and cultural specificities.

Does Native Script Exposure Influence Second Language Early Literacy Skills?: A Preliminary Study in South Indian Preschoolers

The preschool period is marked by the development of several domains such as communication, cognition, social skills, and literacy skills. As language and literacy skills overlap during the preschool period, it is important to understand the dynamics of language and literacy in early school years. Due to language diversity, India does not bear a single-language system, and often the language spoken at home may not be the same at school for curricular instructions. Therefore, the present study focuses on the influence of script in bi- or multilingual scenarios in India. More importantly, the home language may or may not have its specific script; thus, facilitating early literacy skills at home can be questionable. The study followed a cross-sectional study design. One hundred and forty participants were divided into two groups based on their native language (Malayalam and Tulu groups). Each group was further divided based on their age, younger and older groups. An early literacy checklist and a parent perception questionnaire were developed to assess the early literacy skills in second language (L2). The findings revealed a developmental trend in early literacy skills in children with the older group performing better than the younger group. The study results also shed light on this less researched domain of influence of native script on L2 learning in a linguistically diverse country like India. The study's findings emphasize the parental understanding of the importance of home literacy–based activities for children and evaluation of early literacy skills which will help in early identification and treatment.

Do Children Need Adult Support During Sociodramatic Play to Develop Executive Functions? Experimental Evidence

The cultural-historical approach provides the deep theoretical grounds for the analysis of children’s play. Vygotsky suggested three critical features of play: switching to an imaginary situation, taking on a play role, and acting according to a set of rules defined by the role. Collaboration, finding ideas and materials for creating an imaginary situation, defining play roles, and planning the plot are complex tasks for children. However, the question is, do children need educator’s support during the play to develop their executive functions, and to what extent? This experimental study was aimed at answering this inquiry. The four modes of sociodramatic play were created which differed in the adult intervention, from non-involvement in the play to its entire organization. The play could be child-led (with adult help), adult-led, or free (without any adult intervention); and there was also a control group where the children heard the same stimulus stories as the other groups but then followed them up with a drawing activity instead of a play activity. The study revealed that, firstly, the ways of educator’s involvement in the play differed in their potential in respect to the development of executive functions, and, secondly, this influence was not equal for different components of executive functions. Free play in the experiment was not a beneficial condition for the development of any of the studied components of executive functions, compared to the conditions involving the participation of an adult in the play. Furthermore, the type of adult intervention stimulated the development of various executive functions. The entire organization of the play by the adult had a positive impact of their general development. In contrast, the adult’s assistance in the organization of the children’s play had a positive effect on the development of inhibitory control. The study results can be helpful when considering educational practices within a cultural-historical approach to engaging the potential of play in children’s learning and development around the world.

Assessing Computational Methods to Quantify Mother-Child Brain Synchrony in Naturalistic Settings Based on fNIRS Signals

Mother-child brain-to-brain synchrony captures the temporal similarities in brain signals between dyadic partners, and has been shown to emerge during the display of joint behaviours. Despite the rise in the number of studies that investigate synchrony in naturalistic contexts, the use of varying methodological approaches to compute synchrony remains a central problem. When dyads engage in unstructured social interactions, the wide range of behavioural cues they display contribute to the use of varying lengths of signals to compute synchrony. The present functional Near-infrared Spectroscopy (fNIRS) study investigates how different methods to quantify brain signals during joint and non-joint portions of dyadic play affect the outcome of brain-to-brain synchrony. Three strategies to cope with unstructured data are tested and different signal lengths of 15, 20, 25, 30, 35, 40, 45s were used to determine the optimal method to sensitively capture synchrony. Results showed that using all available portions of the signals generated a greater number of less conservative results compared to the other two strategies, which were to compute the average synchrony for the joint and non-joint signals portions and to compute the difference between the average synchrony of joint and non-joint portions. From the different signal durations, only length portions of 25s to 35s generated significant results. These findings demonstrate that differences in computational approaches and signal lengths affect synchrony measurements and should be considered in naturalistic synchrony studies.

Play in Relation to Autism Traits in Young Children at Elevated Likelihood for Autism Spectrum Disorder

Play of younger siblings of children with autism spectrum disorder (ASD) (siblings; n = 44), very preterm children (preterms; n = 44), and children at typical likelihood for ASD (n = 36) was observed at 24 months. Children with ASD and atypical development engaged less in spontaneous (pre-)symbolic play than typically developing children. Total duration of spontaneous and elicited (pre-)symbolic play was associated with later ASD traits in siblings. However, no association between most play variables and ASD traits was found in preterms. This suggests possible different ASD-trajectories between siblings and preterms. Thus, spontaneous (pre-)symbolic play may be indicative of developmental challenges across several populations, and results highlight the need to move beyond studying only siblings in order to broaden our understanding of ASD.

Child Adjustment During COVID-19: The Role of Economic Hardship, Caregiver Stress, and Pandemic Play

The coronavirus disease 2019 (COVID-19) led to many lifestyle changes and economic hardships for families with young children. Previous research on risk and resilience highlights that children's adjustment to family hardships is influenced by caregiver stress, but individual child behaviors and characteristics may protect children from negative outcomes. Interestingly, many children have been reported to incorporate COVID-19 themes in their pretend play. Theory suggests children may do so to cope with pandemic-related stress, but no empirical studies have explored this possibility. The purpose of this study was to understand the process by which COVID-19 economic hardships experienced by a family were related to children's emotional well-being and development and to investigate how this process may vary as a function of children's engagement in pandemic-related pretend play. Caregivers (N = 99; mostly high earning families) of preschoolers ages 3-6 years (51% girls, 82% White) living in the United States participated in an online survey at two time points during the pandemic. Result revealed that COVID-19 economic hardships were related to increased caregiver stress, which, in turn, was associated with children's emotional distress and poorer self-regulation. However, engaging in pandemic-related pretend play appeared to protect children's well-being by weakening the adverse association between caregivers' stress and children's emotional distress. Thus, addressing caregiver stress levels and allowing children an outlet to cope with challenges through pretend play could have crucial protective effects on early development and well-being during times of crisis.

Pretend play ability in preschool-aged children with an acquired brain injury

INTRODUCTION

This study compares the self-initiated pretend play abilities of preschool-aged children with an acquired brain injury, with the self-initiated pretend play ability of their neurotypical peers.

METHOD

A non-experimental group comparison was conducted between 22 preschool-aged neurotypical children (M = 52.8 months, SD = 7.1 months) and 21 children with an acquired brain injury (ABI, M = 50.5 months, SD = 11.9 months), who had been discharged from inpatient rehabilitation and who were able to engage in a play session. The children were assessed individually using the Child-Initiated Pretend Play Assessment (ChIPPA).

RESULTS

The children with an ABI had significantly lower scores in pretend play ability than their neurotypical peers as measured by the percentage of elaborate play actions in both the conventional (P < .000) and symbolic (P < .000) sections of the ChIPPA, as well as the number of object substitutions (P < .000). The children with an ABI completed significantly less of the play time required compared with their neurotypical peers (P = .001); 66% could not play for the required time. There was no significant difference in the ChIPPA scores of the children with an ABI injured before and after the age of 18 months, nor between children with a severe or moderate injury.

CONCLUSION

The quality and the quantity of pretend play of preschool-aged children with an ABI are significantly below that of their neurotypical peers. Assessment of pretend play ability and direct intervention in ABI rehabilitation by occupational therapists is essential to enable children with an ABI to participate in pretend play and garner the developmental benefit this affords.

Symbolic play provides a fertile context for language development

In this study, we test the hypothesis that symbolic play represents a fertile context for language acquisition because its inherent ambiguity elicits communicative behaviors that positively influence development. Infant-caregiver dyads (N = 54) participated in two 20-minute play sessions six months apart (Time 1 = 18 months, Time 2 = 24 months). During each session, the dyads played with two sets of toys that elicited either symbolic or functional play. The sessions were transcribed and coded for several features of dyadic interaction and language; infants' linguistic proficiency was measured via parental report. The two contexts elicited different communicative and linguistic behaviors. Notably, the symbolic play condition resulted in significantly greater conversational turn-taking than functional play, and also resulted in the greater use of questions and mimetics in infant-directed speech (IDS). In contrast, caregivers used more imperative clauses in functional play. Correlational and regression analyses showed that frequent properties of symbolic play (i.e., turn-taking, yes-no questions, mimetics) were positively related to infants' language proficiency, whereas frequent features of functional play (i.e., imperatives in IDS) were negatively related. The results provide evidence supporting the hypothesis that symbolic play is a fertile context for language development, driven by the need to negotiate meaning.

Doll play prompts social thinking and social talking: Representations of internal state language in the brain

Doll play provides opportunities for children to practice social skills by creating imaginary worlds, taking others' perspectives, and talking about others' internal states. Previous research using functional near-infrared spectroscopy (fNIRS) found a region over the posterior superior temporal sulcus (pSTS) was more active during solo doll play than solo tablet play, implying that doll play might present opportunities for rehearsing theory of mind and empathy skills, even when playing alone. In this research, we addressed this more directly by investigating 4-8-year-old children's (N = 33) use of internal state language (ISL; i.e., references to emotions, desires, and cognitions) when playing with dolls and on tablets, both by themselves and with a social partner, and their associated brain activity in the pSTS using fNIRS. We found that children used more ISL about others when playing with dolls than when playing on tablets, particularly when they were playing alone. This mirrored the patterns seen in pSTS activity in previous research. When individual variability in ISL about others was considered, more ISL about others was linked to stronger pSTS activation. Thus, variability in pSTS activity during play is not about the perceptual or physical differences between toys (e.g., dolls are more human-like) but about what children think about when they engage in different kinds of play. This is the first research to investigate brain activity during spontaneously occurring ISL and indicates that children have a tendency to take and discuss others' perspectives during doll play, with implications for social processing in the brain.

Short-Term Effects of Video-Games on Cognitive Enhancement: the Role of Positive Emotions

According to established background knowledge, playing is essential in human development and a power remediation tool in clinical populations. In clinical interventions, the beneficial roles of playing have often been sought and investigated in the specific features of the game, rather than in the positive emotions generated by playing. However, regardless of game specifications, cognitive enhancement could be driven by the emotions linked to play. Establishing the causal connections between play and cognitive enhancement should allow us to determine how to involve play in therapy, prevention and educational programmes. Today, video-gaming is one of the most diffused forms of play. In the first crossover randomized controlled trial, we compared the short-term effects induced by shooting and puzzle video-games in visual perception, sensorimotor and reading skills in children with developmental coordination disorder and dyslexia. The funnier and more activating game enhanced breadth of visual perception and reduced sensorimotor and reading disorders. Visual perception, sensorimotor and reading improvements correlated with fun. In the second crossover randomized controlled trial, comparing the effects of the same shooting with a fighting video-game in healthy young adults, we show that regardless of game characteristics, changes in positive emotions correlated with contextual reading enhancement, while play-driven biochemical activation boosted single word and pseudoword reading. The short-term effects induced by play could be a useful clinical tool for the prevention and treatment of multiple cognitive disorders.

Development of Emotion Regulation in Typically Developing Children

Emotion regulation (ER) is a complex process that combines inherent as well as environmental and learned components of reactivity and regulation. Elements of ER are present from birth and are elaborated across development. An understanding of emotion dysregulation requires careful examination of all the elements that constitute typical ER so that relevant domains can be therapeutically targeted. This contribution reviews the development of ER in typically developing youth to set the stage for discussion of points of intervention.

You Pretend, I Laugh: Associations Between Dyadic Pretend Play and Children's Display of Positive Emotions

Background: Understanding how pretend play is related to positive emotions is important for supporting children's development and promoting their wellbeing. However, previous studies have mainly examined this association at individual levels and overlooked the potential links at interpersonal levels. This is an important knowledge gap because pretend play is commonly performed in social contexts. The current study investigates how peer pretend play is associated with children's display of positive emotions at both individual and dyadic levels.

Methods: One hundred and eight Chinese children (M_age = 8.95 years, SD = 0.99, 51.9% girls) were observed playing in peer dyads with toys. An interaction of 10 min was coded for each child's pretend play behavior, social and emotional pretend play themes, and display of positive emotions. Multilevel modeling was used to examine age and gender differences in peer pretend play. Actor–Partner Interdependence Models (APIM) were estimated to test the hypothesized associations between dyadic pretend play and children' display of positive emotions.

Results: Compared to children whose playmates engaged in less pretend play, children whose playmates engaged in more pretend play were more likely to display positive emotions (p = 0.021). Additionally, children's display of positive emotions was predicted by both their own (p = 0.027) and their playmate's (p = 0.01) pretend play with emotional themes. Compared to younger children, older children were less likely to engage in pretend play (p = 0.002), but more likely to engage in pretend play with social themes (p = 0.03) when the total frequency of pretend play was controlled for. Boys were 4.9 times and 2.16 times as likely as girls to create aggressive pretend themes (p < 0.001) and non-aggressive negative pretend themes (p = 0.007), respectively. No significant gender differences were found in positive pretend themes.

Conclusions: Pretending with peers may increase not only children's own, but also their play partner's display of positive emotions. Pretend play may not simply decline in middle childhood as previously assumed.

Pretending emotions in the early years: The role of language and symbolic play

Although 3-year-old children sometimes simulate emotions to adapt to social norms, we do not know if even younger children can pretend emotions in playful contexts. The present study investigated (1) what emotions infants of 1-2 years old are capable of pretending and (2) the possible role of language and symbolic play in the ability to pretend emotions. The sample included 69 infants aged 18 to 31 months and their parents. Infants were administrated the Test of Pretend Play, and their parents responded to the MacArthur-Bates CDI-II inventory, part of the MacArthur-Bates CDI-I, and a questionnaire about the expression of pretend emotions. Results suggest that very young children simulate emotions. Furthermore, children's simulation of emotions was related to both symbolic play and language. Specifically, the ability to label emotions was linked to the ability to simulate them. The role of language and symbolic play in the development of the capacity to express and understand pretend emotions is discussed.

Exploring the Benefits of Doll Play Through Neuroscience

It has long been hypothesized that pretend play is beneficial to social and cognitive development. However, there is little evidence regarding the neural regions that are active while children engage in pretend play. We examined the activation of prefrontal and posterior superior temporal sulcus (pSTS) regions using near-infrared spectroscopy while 42 4- to 8-year-old children freely played with dolls or tablet games with a social partner or by themselves. Social play activated right prefrontal regions more than solo play. Children engaged the pSTS during solo doll play but not during solo tablet play, suggesting they were rehearsing social cognitive skills more with dolls. These findings suggest social play utilizes multiple neural regions and highlight how doll play can achieve similar patterns of activation, even when children play by themselves. Doll play may provide a unique opportunity for children to practice social interactions important for developing social-emotional skills, such as empathy.

The relevance of a rodent cohort in the Consortium on Individual Development

One of the features of the Consortium on Individual Development is the existence of a rodent cohort, in parallel with the human cohorts. Here we give an overview of the current status. We first elaborate on the choice of rat and mouse models mimicking early life adverse or beneficial conditions during development. We performed a systematic literature search on early life adversity and adult social behavior to address the status quo. Next, we describe the behavioral tasks we used and designed to examine behavioral control and social competence in rodents. The results so far indicate that manipulation of the environment in the first postnatal week only subtly affects social behavior. Stronger effects were seen in the model that targeted early adolescence; once adult, these rats are characterized by increased attention, a higher degree of impulsiveness and reduced social interest in peers. Many experiments in our rodent models with tightly controlled conditions were inspired by findings in human cohorts, and now allow in-depth mechanistic investigations. Vice versa, some of the findings in rodents are currently followed up by dedicated investigations in the human cohorts. This exemplifies the added value of animal investigations in a consortium encompassing primarily human developmental cohorts.

Coping with paediatric illness: Child's play? Exploring the effectiveness of a play- and sports-based cognitive behavioural programme for children with chronic health conditions

Little is known about how play affects the development of children with a chronic condition. Studying play poses major methodological challenges in measuring differences in play behaviour, which results in a relative scarcity of research on this subject. This pilot study seeks to provide novel directions for research in this area. The effectiveness of a play- and sports-based cognitive behavioural programme for children (8-12 years) with a chronic condition was studied. The children and parents completed a battery of measurement tools before and after the programme. Moreover, the application of automated computer analyses of behaviour was piloted. Behaviour (Child Behavior Checklist) seemed to be positively affected by the programme. An increase in psychological well-being was observed (KIDSCREEN). Perceived competence (Self-Perception Profile for Children) and actual motor competence (Canadian Agility and Movement Skill Assessment) did not show any positive trends. These results of 13 participants suggest that children might learn to better cope with their illness by stimulating play behaviour. For the analysis of the effectiveness of programmes like this, we therefore propose to focus on measuring behaviour and quality of life. In addition, pilot measurements showed that automated analysis of play can provide important insights into the participation of children.

Understanding dual realities and more in VR

The five commentaries on our paper (Pan & Hamilton, 2018, Br. J. Psychol.) provide a useful summary of the key issues we raise, and also bring to the foreground some new and important questions, touching on a range of issues including presence and the conceptualization of dual realities. We highlight here some important themes and directions for future investigation.

Play and optimal welfare: Does play indicate the presence of positive affective states?

Play is commonly used to assess affective states in both humans and non-human animals. Play appears to be most common when animals are well-fed and not under any direct threats to fitness. Could play and playfulness therefore indicate pre-existing positive emotions, and thence optimal animal welfare? We examine this question by surveying the internal and external conditions that promote or suppress play in a variety of species, starting with humans. We find that negative affective states and poor welfare usually do suppress play (although there are notable exceptions where the opposite occurs). Furthermore, research in children suggests that beyond the frequency or total duration of play, poor welfare may additionally be reflected in qualitative aspects of this heterogeneous behaviour (e.g. display of solitary over social play; and the 'fragmentation' of play bouts) that are often overlooked in animals. There are surprisingly few studies of play in subjects with pre-existing optimal welfare or in unambiguously highly positive affective states, making it currently impossible to determine whether play can distinguish optimal or good welfare from merely neutral welfare. This therefore represents an important and exciting area for future research.
