The old,the new,and the in‐between: Preadolescents’ use of stylistic variation in speech in projecting their own identity in a culturally changing environment

Cultural learning begins early, with infants’ and young children's initial imitations of group‐specific local behaviors. Comparatively little is known about cultural development in older children, whose more advanced socio‐cognitive skills can moderate their decisions about adherence to the established cultural conventions and acceptance of new norms. Focusing on the acquisition of a regional dialect, the current study was conducted in a small community in western North Carolina, whose rich Appalachian heritage grew from distinctive cultural and living traditions. The region has gradually opened up to outside influences and the local culture is now shifting toward mainstream American socio‐cultural norms. The study sought to determine how preadolescents positioned themselves in this socio‐culturally changing environment. Using detailed acoustic analysis to measure stylistic variation in speech in 9–12‐year‐olds and perceptual ratings to verify its salience, we examined the pronunciation of the vowel /ai/ to test children's adherence to the old Appalachian identity marker (the monophthong) and their acceptance of the modern American society (the diphthong). As an innovation, children created an intermediate phonetic variant that reduced the pronunciation differences between the old and modern patterns. Demonstrating the ability to adapt speech style to context, they increased the degree of diphthongization in this /ai/‐variant in careful speech (reading), and reduced it in casual conversations. Girls’ productions were more diphthongal than were boys’ in reading but not in conversations. The new variant in children represents regional dialect levelling, and likely results from their accommodation to the changing environment, which promotes reduction of old marked forms.     

Chimpanzees help others with what they want; children help them with what they need

Humans, including young children, are strongly motivated to help others, even paying a cost to do so. Humans’ nearest primate relatives, great apes, are likewise motivated to help others, raising the question of whether the motivations of humans and apes are the same. Here we compared the underlying motivation to help in human children and chimpanzees. Both species understood the situation and helped a conspecific in a straightforward situation. However, when helpers knew that what the other was requesting would not actually help her, only children gave her what she needed instead of giving her what she requested. These results suggest that both chimpanzees and human children help others but the underlying motivation for why they help differs. In comparison to chimpanzees, young children help in a paternalistic manner. The evolutionary hypothesis is that uniquely human socio‐ecologies based on interdependent cooperation gave rise to uniquely human prosocial motivations to help others paternalistically.     

The social foundation of executive function

In this study, we propose that infant social cognition may ‘bootstrap' the successive development of domain‐general cognition in line with the cultural intelligence hypothesis. Using a longitudinal design, 6‐month‐old infants (N = 118) were assessed on two basic social cognitive tasks targeting the abilities to share attention with others and understanding other peoples' actions. At 10 months, we measured the quality of the child's social learning environment, indexed by parent's abilities to provide scaffolding behaviors during a problem‐solving task. Eight months later, the children were followed up with a cognitive test‐battery, including tasks of inhibitory control and working memory. Our results showed that better infant social action understanding interacted with better parental scaffolding skills in predicting simple inhibitory control in toddlerhood. This suggests that infants' who are better at understanding other's actions are also better equipped to make the most of existing social learning opportunities, which in turn may benefit future non‐social cognitive outcomes.     

The ontogeny of intentional communication in chimpanzees in the wild

The onset of intentional communication in children's first year of life represents a major milestone in human cognitive development. Similarly, it is well established that our closest living relatives, the great apes, communicate with signals characterized by at least first‐order intentionality. Despite the well‐documented influence of developmental experiences on socio‐cognitive abilities in apes, the developmental trajectory of intentional signal use as well as effects of social exposure remain poorly understood under naturalistic conditions. Here, we addressed these issues by studying the ontogeny of intentional communication in chimpanzee infants of two subspecies (Pan troglodytes schweinfurthii/verus) and communities living in their natural environments. Overall, we found that gestures and bimodal signal combinations were most commonly accompanied by markers of intentional communication: audience checking, persistence to the goal, and sensitivity to recipient’s attentional state. Within individuals, the proportion of communicative behaviours associated with goal persistence and sensitivity to attention increased with age. Cross‐sectional comparisons between infants revealed an age effect on the use of audience checking. Context, interaction partner and site affiliation affected the production of specific markers irrespective of infants' age. The present study provided hitherto undocumented evidence for the development of three important markers of intentional communication in great apes. Moreover, our results suggest that social exposure impacts early intentional signal use.     

Two‐year‐old children but not domestic dogs understand communicative intentions without language,gestures, or gaze

Infants can see someone pointing to one of two buckets and infer that the toy they are seeking is hidden inside. Great apes do not succeed in this task, but, surprisingly, domestic dogs do. However, whether children and dogs understand these communicative acts in the same way is not yet known. To test this possibility, an experimenter did not point, look, or extend any part of her body towards either bucket, but instead lifted and shook one via a centrally pulled rope. She did this either intentionally or accidentally, and did or did not address her act to the subject using ostensive cues. Young 2‐year‐old children but not dogs understood the experimenter's act in intentional conditions. While ostensive pulling of the rope made no difference to children's success, it actually hindered dogs' performance. We conclude that while human children may be capable of inferring communicative intent from a wide variety actions, so long as these actions are performed intentionally, dogs are likely to be less flexible in this respect. Their understanding of communicative intention may be more dependent upon bodily markers of communicative intent, including gaze, orientation, extended limbs, and vocalizations. This may be because humans have come under selective pressure to develop skills for communicating with absent interlocutors – where bodily co‐presence is not possible.     

Gender‐related differences in neonatal imitation

Socio‐emotional behaviour is in part sex‐related in humans, although the contribution of the biological and socio‐cultural factors is not yet known. This study explores sex‐related differences during the earliest communicative exchange, the neonatal imitation in 43 newborn infants (3–96 hours old) using an index finger extension imitative gesture. Results showed that although the experimenter presented comparable stimuli to both sexes, and the total number of movements was similar in boys and girls, girls showed more fine motor movements, a higher number of specific imitative gestures, responded faster during the imitation and showed a higher baseline heart rate during the experiment. Newborn girls, with their faster and more accurate imitative abilities, may create a more responsive and interactive social environment, which in turn may lead to differences in socio‐emotional and cognitive development between girls and boys.

Finding a home: Developmental and neurobiological perspectives on cultural models

This article looks at cultural models in the light of human development, and neurobiological findings in motivation, learning, and cognition. It is argued that at the individual level, the acquisition of cultural models relies on several innate, neurobiologically based motivational, learning, and cognitive systems. These are: (a) a primary motivation to form social bonds which is driven by affect; (b) highly specialized social learning circuits, involving, but not limited to, mirror neuron systems, that facilitate the encoding of social information through implicit, embodied, imitational learning processes; and (c) the formation of culturally based templates for behavior and cognition centered around structures, collectively known as the “default mode network,” which is essential to self‐understanding, autobiographical memory, social cognition, prospection, and theory‐of‐mind. Cultural models, it is argued, are acquired through innate motivational processes that tie the individual emotionally to a secure base of familiar people and customs. This instinctual desire for proximity to others facilitates the efficient, largely implicit, patterning of knowledge and expectations. Shared knowledge and expectations, in turn, create a common, mostly implicit or unconscious, experience of subjectivity within groups. This allows each individual to automatically and effortlessly interact with similarly enculturated others.     

Preliminary Evaluation of a Social Skills Training and Facilitated Play Early Intervention Programme for Extremely Shy Young Children in China

The goal of this study was to provide a preliminary evaluation of a social skills and facilitated play early intervention programme to promote social interaction, prosocial behaviours and socio‐communicative skills among young extremely shy children in China. Participants were a sample of n = 16 extremely shy young children attending kindergarten in Shanghai, China. Children were randomly assigned to either the Social Skills Facilitated Play or comparison condition. Baseline, post‐intervention and 2‐month follow‐up measures included observations of children's social behaviours in quartets of novel peers. Result indicated that as compared with shy controls, shy children who participated in the Social Skills Training Facilitated Play programme were observed to demonstrate significantly greater post‐intervention frequencies of peer interactions (e.g. group play and peer conversation) and prosocial behaviours (e.g. cooperation, sharing and making/accepting social initiations) during unstructured free play with novel peers, as well as better social‐communicative competence during a speech task. Almost all of these improvements were maintained 2 months post‐intervention. Results are discussed in terms of the importance of developing and refining early intervention programmes for extremely shy young children in China. Copyright © 2016 John Wiley & Sons, Ltd.     

Embodied Cultural Cognition: Situating the Study of Embodied Cognition in Socio‐Cultural Contexts

Embodiment research has demonstrated that cognition is grounded in bodily interactions with the environment and that abstract concepts are tied to the body’s sensory and motor systems. Building upon this embodiment perspective and advancing our understanding, we discuss the extension of embodied cultural cognition. We propose that some associations between bodily experiences and abstract concepts are not randomly formed; rather, the development of such associations is situated in a socio‐cultural context, informed by cultural imperatives, values, and habits. We draw evidence supporting this view of embodied cultural cognition in body–mind linkages manifested in construal of emotions, time perception, person perception, social power, and moral reasoning. To further extend this research avenue that synthesizes the studies of embodied cognition and culture, we also suggest potential future research directions inspired by this view. This embodied cultural cognition account is useful in understanding and organizing accumulating discoveries of cultural variations in embodiments; it also highlights the social situatedness of embodied cognition and is, therefore, highly compatible with theorizing and research in social and cultural psychology.     

Metacognitive scaffolding boosts cognitive and neural benefits following executive attention training in children

Interventions including social scaffolding and metacognitive strategies have been used in educational settings to promote cognition. In addition, increasing evidence shows that computerized process‐based training enhances cognitive skills. However, no prior studies have examined the effect of combining these two training strategies. The goal of this study was to test the combined effect of metacognitive scaffolding and computer‐based training of executive attention in a sample of typically developing preschoolers at the cognitive and brain levels. Compared to children in the regular training protocol and an untrained active control group, children in the metacognitive group showed larger gains on intelligence and significant increases on an electrophysiological index associated with conflict processing. Moreover, changes in the conflict‐related brain activity predicted gains in intelligence in the metacognitive scaffolding group. These results suggest that metacognitive scaffolding boosts the influence of process‐based training on cognitive efficiency and brain plasticity related to executive attention.     

Young children's difficulty with inhibitory control in a social context1

Abstract: The authors’ prior research has documented that young children's behaviors in the Dimensional Change Card Sorting (DCCS) task can be influenced by their observation of another person performing the task and has suggested that young children committed perseverative errors in a social context. The present study explored whether children who committed perseverative errors in the social context also committed perseverative errors in the standard DCCS task. Three‐ and 4‐year‐old children were given the standard DCCS and the observation version of the DCCS, and the relationship between them was examined. The results showed that the correlation between these two tasks was significant. Furthermore, 4‐year‐old children displayed more difficulty in the observation version than in the standard DCCS, whereas 3‐year‐olds did not. The results are discussed in terms of the development of inhibitory control and social cognition.     

The ultra‐social animal

In evolutionary perspective, what is most remarkable about human sociality is its many and diverse forms of cooperation. Here, I provide an overview of some recent research, mostly from our laboratory, comparing human children with their nearest living relatives, the great apes, in various tests of collaboration, prosocial behavior, conformity, and group‐mindedness (e.g., following and enforcing social norms). This is done in the context of a hypothetical evolutionary scenario comprising two ordered steps: a first step in which early humans began collaborating with others in unique ways in their everyday foraging and a second step in which modern humans began forming cultural groups. Humans' unique forms of sociality help to explain their unique forms of cognition and morality. © 2014. The Authors. European Journal of Social Psychology published by John Wiley & Sons, Ltd.     

Making inferences about the location of hidden food: social dog, causal ape

Domestic dogs (Canis familiaris) and great apes from the genus Pan were tested on a series of object choice tasks. In each task, the location of hidden food was indicated for subjects by some kind of communicative, behavioral, or physical cue. On the basis of differences in the ecologies of these 2 genera, as well as on previous research, the authors hypothesized that dogs should be especially skillful in using human communicative cues such as the pointing gesture, whereas apes should be especially skillful in using physical, causal cues such as food in a cup making noise when it is shaken. The overall pattern of performance by the 2 genera strongly supported this social-dog, causal-ape hypothesis. This result is discussed in terms of apes' adaptations for complex, extractive foraging and dogs' adaptations, during the domestication process, for cooperative communication with humans.     

Understanding and sharing intentions: the origins of cultural cognition

We propose that the crucial difference between human cognition and that of other species is the ability to participate with others in collaborative activities with shared goals and intentions: shared intentionality. Participation in such activities requires not only especially powerful forms of intention reading and cultural learning, but also a unique motivation to share psychological states with others and unique forms of cognitive representation for doing so. The result of participating in these activities is species-unique forms of cultural cognition and evolution, enabling everything from the creation and use of linguistic symbols to the construction of social norms and individual beliefs to the establishment of social institutions. In support of this proposal we argue and present evidence that great apes (and some children with autism) understand the basics of intentional action, but they still do not participate in activities involving joint intentions and attention (shared intentionality). Human children's skills of shared intentionality develop gradually during the first 14 months of life as two ontogenetic pathways intertwine: (1) the general ape line of understanding others as animate, goal-directed, and intentional agents; and (2) a species-unique motivation to share emotions, experience, and activities with other persons. The developmental outcome is children's ability to construct dialogic cognitive representations, which enable them to participate in earnest in the collectivity that is human cognition.     

How similar are fluid cognition and general intelligence? A developmental neuroscience perspective on fluid cognition as an aspect of human cognitive ability

This target article considers the relation of fluid cognitive functioning to general intelligence. A neurobiological model differentiating working memory/executive function cognitive processes of the prefrontal cortex from aspects of psychometrically defined general intelligence is presented. Work examining the rise in mean intelligence-test performance between normative cohorts, the neuropsychology and neuroscience of cognitive function in typically and atypically developing human populations, and stress, brain development, and corticolimbic connectivity in human and nonhuman animal models is reviewed and found to provide evidence of mechanisms through which early experience affects the development of an aspect of cognition closely related to, but distinct from, general intelligence. Particular emphasis is placed on the role of emotion in fluid cognition and on research indicating fluid cognitive deficits associated with early hippocampal pathology and with dysregulation of the hypothalamic-pituitary-adrenal axis stress-response system. Findings are seen to be consistent with the idea of an independent fluid cognitive construct and to assist with the interpretation of findings from the study of early compensatory education for children facing psychosocial adversity and from behavior genetic research on intelligence. It is concluded that ongoing development of neurobiologically grounded measures of fluid cognitive skills appropriate for young children will play a key role in understanding early mental development and the adaptive success to which it is related, particularly for young children facing social and economic disadvantage. Specifically, in the evaluation of the efficacy of compensatory education efforts such as Head Start and the readiness for school of children from diverse backgrounds, it is important to distinguish fluid cognition from psychometrically defined general intelligence.     

Family size and intelligence revisited: the role of emotional intelligence.

Studies examining the link between family size and intelligence have consistently found a negative relationship. Children born into larger families tend to score lower on intelligence tests than children raised in smaller families. One recurrent but unexplained finding is that the relation between intelligence and number of siblings is consistently significant for verbal intelligence but inconsistent for nonverbal intelligence. Here, we conceptualize emotional intelligence as one facet of nonverbal intelligence. The research develops a measure of emotional intelligence and uses it to test the hypothesis that emotional intelligence is positively correlated with family size. The results, based upon a sample of graduate students, support the hypothesized relationship. Implications for the study of family size and intelligence, for refining the conceptualizations and measures of nonverbal intelligence, and for leadership theory, are discussed.     

Young Children's Knowledge of the Representational Function of Pictorial Symbols: Development Across the Preschool Years in Three Cultures

Three- to 5-year-old children's knowledge that pictures have a representational function for others was investigated using a pictorial false-belief task. In Study 1, children passed the task at around 4 years old, and performance was correlated with standard false-belief and pictorial symbol tasks. In Study 2, the performance of children from two cultural settings who had very little exposure to pictures during the first 3 years (Peru, India) was contrasted with that of children from Canada. Performance was better in the Canadian than Peruvian and Indian samples on the picture false-belief task and drawing tasks but not on the standard false-belief measure. In all settings, children passed drawing and standard false-belief tasks either concurrently with, or prior to, passing the picture false-belief task. The findings suggest that children's explicit knowledge of the representational function of pictorial symbols matures in the late preschool years and develops more rapidly in cultures that strongly promote the symbolic use of pictures early in life.     

Listening comprehension in preschoolers: The role of memory

The current study analyzed the relationship between text comprehension and memory skills in preschoolers. We were interested in verifying the hypothesis that memory is a specific contributor to listening comprehension in preschool children after controlling for verbal abilities. We were also interested in analyzing the developmental path of the relationship between memory skills and listening comprehension in the age range considered. Forty‐four, 4‐year‐olds (mean age = 4 years and 6 months, SD =4 months) and 40, 5‐year‐olds (mean age = 5 years and 4 months, SD =5 months) participated in the study. The children were administered measures to evaluate listening comprehension ability (story comprehension), short‐term and working memory skills (forward and backward word span), verbal intelligence and receptive vocabulary. Results showed that both short‐term and working memory predicted unique and independent variance in listening comprehension after controlling for verbal abilities, with working memory explaining additional variance over and above short‐term memory. The predictive power of memory skills was stable in the age range considered. Results also confirm a strong relation between verbal abilities and listening comprehension in 4‐ and 5‐year‐old children.     

A comparison of temperament in nonhuman apes and human infants

The adaptive behavior of primates, including humans, is often mediated by temperament. Human behavior likely differs from that of other primates in part due to temperament. In the current study we compared the reaction of bonobos, chimpanzees, orangutans, and 2.5-year-old human infants to novel objects and people - as a measure of their shyness-boldness, a key temperamental trait. Human children at the age of 2.5 years avoided novelty of all kinds far more than the other ape species. This response was most similar to that seen in bonobos and least like that of chimpanzees and orangutans. This comparison represents a first step in characterizing the temperamental profiles of species in the hominoid clade, and these findings are consistent with the hypothesis that human temperament has evolved since our lineage diverged from the other apes in ways that likely have broad effects on behavior. These findings also provide new insights into how species differences in ecology may shape differences in temperament.     

Conservation and conversation types: Forms of recognition and cognitive development

While the productive role of social interaction between peers in promoting cognitive development has been clearly established, the communicative processes through which this is achieved is less clearly understood. Earlier work has established that different types of conversation become established between children as they work together on a problem, and that these types have different implications for the progress of a non‐conserver. The paper focuses on the forms of recognition that emerge within these different conversation types. It reports further analyses of a study in which 226 6.5‐ to 7.5‐year‐old children were presented with a Piagetian task of conservation of liquid. Conservers and non‐conservers were asked to discuss in pairs their conflicting answers and agree upon a joint response. Cognitive progress was assessed by pre‐ to post‐test gains. Analyses of the conversational moves made by each of the participants to the conversation indicates that both non‐conservers and conservers not only make characteristic contributions, but that these contributions vary across the conversation types, and hence also relate differentially to the non‐conserver's progress. More detailed qualitative analyses of the different conversation types provide insights into the ways in which different forms of recognition emerge through these interactions. These results are discussed in relation to a socio‐cognitive account of development.
