In Play=Learning, top experts in child development and learning contend that in over-emphasizing academic achievement, our culture has forgotten about the importance of play for children’s development.

Executive functions in childhood predict important life outcomes. Thus, there is great interest in attempts to improve executive functions early in life. Many interventions are led by trained adults, including structured training activities in the lab, and less-structured activities implemented in schools. Such programs have yielded gains in children’s externally-driven executive functioning, where they are instructed on what goal-directed actions to carry out and when. However, it is less clear how children’s experiences relate to their development of self-directed executive functioning, where they must determine on their own what goal-directed actions to carry out and when. We hypothesized that time spent in less-structured activities would give children opportunities to practice self-directed executive functioning, and lead to benefits. To investigate this possibility, we collected information from parents about their 6-7 year-old children’s daily, annual, and typical schedules. We categorized children’s activities as “structured” or “less-structured” based on categorization schemes from prior studies on child leisure time use. We assessed children’s self-directed executive functioning using a well-established verbal fluency task, in which children generate members of a category and can decide on their own when to switch from one subcategory to another. The more time that children spent in less-structured activities, the better their self-directed executive functioning. The opposite was true of structured activities, which predicted poorer self-directed executive functioning. These relationships were robust (holding across increasingly strict classifications of structured and less-structured time) and specific (time use did not predict externally-driven executive functioning). We discuss implications, caveats, and ways in which potential interpretations can be distinguished in future work, to advance an understanding of this fundamental aspect of growing up.

Self-regulation emerges throughout early childhood, and predicts later success in socially and cognitively challenging situations. Vygotsky proposed that symbols, particularly words, serve as mental tools to be used in service of self-regulation. Cross-sectional research indicates a positive but inconsistent association between language and self-regulation skills throughout toddlerhood, but research has not accounted for general cognitive development, nor gender differences in these domains. We used growth modeling of longitudinal data for 120 toddlers collected when children were 14, 24, and 36 months to test the impact of two expressive language skills – spoken vocabulary and talkativeness – on the growth of toddlers’ self-regulation, and to determine whether associations between these domains exist when controlling for cognitive development. Results reveal gender differences in self-regulation trajectories, and in the impact of language on self-regulation. Vocabulary is a better predictor of self-regulation than talkativeness, and both concurrent and prior vocabulary positively predicted children’s levels of self-regulation. When cognitive development was controlled, 24-month vocabulary still predicted the trajectory of self-regulation. Results reveal that, even in early development, words are tools that can be applied to the task of self-regulation, and may be a more necessary tool for boys than for girls at this age.

We report on the emergence of functional flexibility in vocalizations of human infants. This vastly underappreciated capability becomes apparent when prelinguistic vocalizations express a full range of emotional content—positive, neutral, and negative. The data show that at least three types of infant vocalizations (squeals, vowel-like sounds, and growls) occur with this full range of expression by 3–4 mo of age. In contrast, infant cry and laughter, which are species-specific signals apparently homologous to vocal calls in other primates, show functional stability, with cry overwhelmingly expressing negative and laughter positive emotional states. Functional flexibility is a sine qua non in spoken language, because all words or sentences can be produced as expressions of varying emotional states and because learning conventional “meanings” requires the ability to produce sounds that are free of any predetermined function. Functional flexibility is a defining characteristic of language, and empirically it appears before syntax, word learning, and even earlier-developing features presumed to be critical to language (e.g., joint attention, syllable imitation, and canonical babbling). The appearance of functional flexibility early in the first year of human life is a critical step in the development of vocal language and may have been a critical step in the evolution of human language, preceding protosyntax and even primitive single words. Such flexible affect expression of vocalizations has not yet been reported for any nonhuman primate but if found to occur would suggest deep roots for functional flexibility of vocalization in our primate heritage.

How do children play in different kinds of child care settings? How do child care environments influence their play? How do special-needs children play in integrated and in segregated child care settings? How do adults influence play in child care environments? And what are the long term effects of children’s play in child care? These are among the questions addressed by the psychologists and educators who have contributed to this book. Researchers will find Children’s Play in Child Care Settings to be a valuable review of current theory and research in this area. Practitioners will better understand the ways in which early childhood environments and early childhood educators can facilitate the play of young children in child care settings. And administrators will be able to draw upon the book in designing and implementing early childhood programs for special needs and non-special needs children.

Smiling and laughing appear very early during the first year of life, but little is known about how infants come to appraise a stimulus as humorous. This short-term longitudinal study explored infant humor perception from 5 to 7months of age as a function of parental affect during an absurd event. Using a within-participants design, parents alternated smiling/laughing with emotional neutrality while acting absurdly toward their infants. Group comparisons showed that infants (N=37) at all ages smiled at the event regardless of parental affect but did so significantly longer at 5 and 6months, and more often and sooner at 7months, when parents provided humor cues. Similarly, sequential analyses revealed that after gazing at the event, 7-month-olds were more likely to smile at it only when parents provided humor cues and were comparatively more likely to look away when parents were neutral. Thus, starting at 5months of age, parental affect influenced infants’ affect toward an absurd event, an effect that was magnified at 7months. These results are discussed in the context of emotional contagion, regulation, and the emergence of social referencing.

Semiotic development involves the development of at least two different kinds of meaning: intersubjective and representational. By attending to these two kinds of meaning we are able to predict one of the major transitions in early childhood: the transition to reference. From a dynamic systems perspective we track essential developments which, when all have reached critical values, prompt the transition to referential word production and/or comprehension in the first half of the second year of life. We present the background of the four variables included in the model: (a) representational play, (b) vocalization ability, (c) gesture, and (d) developments in autonomic vocalization culminating in communicative grunts. We further demonstrate their efficacy in predicting the transition in a longitudinal sample of 10 children. Additional study is needed to confirm the role of these developments and to extend the approach to languages other than English and more advanced levels of semiotic development.

Mother-child play of maltreating and nonmaltreating families was analyzed when infants were 12 months old (Time 1), and 2 years old (Time 2), as a context to examine children’s developing cognitive and social skills. At Time 1, infants from abusing families demonstrated less independent and more imitative behavior during play than did infants from neglecting and nonmaltreating families, suggesting a delay in emerging social behaviors. In this longitudinal follow-up, mother-child play was reassessed 1 year later (N = 78), with a focus on children’s engagement in nonplay and pretend play and on children’s abilities to initiate social exchanges and respond to parental requests. Play and social behavior were coded from semistructured and unstructured play paradigms at both time points. Maternal attention-directing behavior and limit setting also was assessed. At Time 2, children from abusing, neglecting, and nonmaltreating families did not differ in cognitive play complexity. However, children from abusing families engaged in less child-initiated play than did children from neglecting and nonmaltreating families, demonstrating less socially competent behavior. Longitudinal analyses revealed child initiated play at Time 2 was negatively associated with abuse and with maternal physical attention directing behavior at Time 1. Child negative reactivity at Time 2 was positively associated with Time 1 maternal physical behavior and child imitation and with Time 2 maternal controlling behavior. Implications for early intervention efforts are emphasized.

Teaching play skills is important for children with autism. The purpose of the present study was to compare effectiveness and efficiency of providing video modeling and graduated guidance together and video modeling alone for teaching role playing skills to children with autism. The study was conducted with four students. The study was conducted by using adapted alternative treatments design. Four kinds of data were collected during the study: effectiveness, efficiency, social validity, and reliability. Both teaching methods were found to be effective in teaching target skills to children with autism. Results of the study were compared with the literature and some recommendations were addressed in the study. (PsycINFO Database Record (c) 2015 APA, all rights reserved). (journal abstract)

The aim of this study was to examine the relation between symbolic play and communicative engagement among children with and without autism. Our predictions were firstly, that in moment-by-moment interactions during semi-structured interactive play with an adult, children with and without autism would tend to show shifts in meanings in symbolic play when engaged in coordinated states of joint engagement (events involving ‘sharing-of-meaning’); secondly, that across atypically developing participants, sharing-of-meaning would (a) correlate with scores on a standardized test of pretend play, and (b) be inversely correlated with scores on the Autism Diagnostic Observation Schedule; and finally, that participants with autism would contrast with matched developmentally delayed participants in manifesting lower levels of joint engagement, lower levels of symbolic play, and fewer shifts in symbolic meaning. Each of these predictions was borne out. The intimate developmental relation between social engagement and symbolic play appears to be important for explaining the developmental psychopathology of autism.
