The sustained effect of emotional signals on neural processing in 12‐month‐olds

Around the end of the first year of life, infants develop a social referencing ability – using emotional information from others to guide their own behavior. Much research on social referencing has focused on changes in behavior in response to emotional information. The present study was an investigation of the changes in neural responses that underlie social referencing behavior, reflected in event‐related potentials (ERPs). Twenty‐six 12‐month‐olds participated in a single‐session visit in which ERPs were recorded both immediately before and after a behavioral intervention in which infants' caregivers provided positive, negative or neutral information about each of three stimuli (ERP data available for n = 17). After the intervention, infants devoted more neural resources to processing negative versus neutral and positive information, as observed in early and late positive‐going components. Changes in neural responses from the pre‐ to post‐intervention recordings clarify this observation, indicating a sustained response in the negative and positive conditions, and a decrease in the neutral condition, suggesting an attenuation effect in the neutral condition. Further, infants who attended most to the objects in the behavioral intervention showed increased neural responses in the negative condition and decreased responses in the positive condition. Taken together, these findings suggest that infants' neural responses are differentially affected by positive, negative and neutral information. Furthermore, the findings highlight the importance of measuring the change in neural responses to better interpret post‐experience responses.     

Children's Explanations as a Window Into Their Intuitive Theories of the Social World

Social categorization is an early emerging and robust component of social cognition, yet the role that social categories play in children's understanding of the social world has remained unclear. The present studies examined children's (N = 52 four‐ and five‐year olds) explanations of social behavior to provide a window into their intuitive theories of how social categories constrain human action. Children systematically referenced category memberships and social relationships as causal‐explanatory factors for specific types of social interactions: harm among members of different categories more than harm among members of the same category. In contrast, they systematically referred to agents' mental states to explain the reverse patterns of behaviors: harm among members of the same category more than harm among members of different categories. These data suggest that children view social category memberships as playing a causal‐explanatory role in constraining social interactions.     

The early development of human mirror mechanisms: evidence from electromyographic recordings at 3 and 6 months

In primates and adult humans direct understanding of others' action is provided by mirror mechanisms matching action observation and action execution (e.g. Casile, Caggiano & Ferrari, 2011). Despite the growing body of evidence detailing the existence of these mechanisms in the adult human brain, their origins and early development are largely unknown. In this study, for the first time, electromyographic (EMG) measures were used to shed light on the emergence of mirror motor mechanisms in infancy. EMG activity was recorded while 6‐ and 3‐month‐old infants watched two videos displaying an agent reaching for, grasping and bringing an object either to the mouth or to the head. Results indicate that the motor system of 6‐month‐olds, but not 3‐month‐olds, was recruited and selectively modulated during observation of the goal‐directed actions, favoring the idea that mirror mechanisms driving action understanding gradually emerge during early development.     

The origins of empathic concern

Recent developments in research cast doubt on early conceptions of young children as primarily egocentric and uncaring of others' needs. Studies reviewed indicate a broad range of social competencies children bring to their interpersonal relationships. As early as 2 years of age, they show (a) the cognitive capacity to interpret, in simple ways, the physical and psychological states of others, (b) the emotional capacity to experience, affectively, the state of others, and (c) the behavioral repertoire that permits the possibility of attempts to alleviate discomfort in others. Both temperament and environment may contribute to individual differences in concern for others. Early socialization experiences that lead to adaptive and maladaptive patterns of responsiveness to others' needs are described. Examples of environmental risk conditions include parental depression, marital discord, parental maltreatment. Implications of this work for broadening existing conceptualizations of empathy and related prosocial orientations are addressed.     

The ontogeny of cumulative culture: Individual toddlers vary in faithful imitation and goal emulation

The success of human culture depends on early emerging mechanisms of social learning, which include the ability to acquire opaque cultural knowledge through faithful imitation, as well as the ability to advance culture through flexible discovery of new means to goal attainment. This study explores whether this mixture of faithful imitation and goal emulation is based in part on individual differences which emerge early in ontogeny. Experimental measurements and parental reports were collected for a group of 2‐year‐old children (N = 48, age = 23–32 months) on their imitative behavior as well as other aspects of cognitive and social development. Results revealed individual differences in children's imitative behavior across trials and tasks which were best characterized by a model that included two behavioral routines; one corresponding to faithful imitation, and one to goal emulation. Moreover, individual differences in faithful imitation and goal emulation were correlated with individual differences in theory of mind, prosocial behavior, and temperament. These findings were discussed in terms of their implications for understanding the mechanisms of social learning, ontogeny of cumulative culture, and the benefit of analyzing individual differences for developmental experiments.     

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.     

Tuning the developing brain to emotional body expressions

Reading others' emotional body expressions is an essential social skill. Adults readily recognize emotions from body movements. However, it is unclear when in development infants become sensitive to bodily expressed emotions. We examined event‐related brain potentials (ERPs) in 4‐ and 8‐month‐old infants in response to point‐light displays (PLDs) of happy and fearful body expressions presented in two orientations (upright and inverted). The ERP results revealed that 8‐month‐olds but not 4‐month‐olds respond sensitively to the orientation and the emotion of the dynamic expressions. Specifically, 8‐month‐olds showed (i) an early (200–400 ms) orientation‐sensitive positivity over frontal and central electrodes, and (ii) a late (700–1100 ms) emotion‐sensitive positivity over temporal and parietal electrodes in the right hemisphere. These findings suggest that orientation‐sensitive and emotion‐sensitive brain processes, distinct in timing and topography, develop between 4 and 8 months of age.     

The Emerging Study of Positive Empathy

Lay intuitions suggest that the ability to share, celebrate, and enjoy others' positive emotions – a phenomenon we term positive empathy – bolsters individual well‐being and relationship strength. However, it is unclear from the current literature whether (i) positive empathy is distinct from highly related constructs and (ii) whether positive empathy is associated with salutary social and personal outcomes. Here, we begin by examining basic evidence suggesting that positive empathy is related to, but independent from, constructs such as general positivity and empathy for others' distress. We then review evidence that positive empathy correlates with increased prosocial behavior, social closeness, and well‐being. Lastly, we discuss open directions for the study of positive empathy, such as investigating the potential role of positive empathy (or its disruption) in psychiatric disorders.     

Longitudinal links between childhood peer acceptance and the neural correlates of sharing

Childhood peer acceptance is associated with high levels of prosocial behavior and advanced perspective taking skills. Yet, the neurobiological mechanisms underlying these associations have not been studied. This functional magnetic resonance imaging study examined the neural correlates of sharing decisions in a group of adolescents who had a stable accepted status (n = 27) and a group who had a chronic rejected status (n = 19) across six elementary school grades. Both groups of adolescents played three allocation games in which they could share money with strangers with varying costs and profits to them and the other person. Stably accepted adolescents were more likely to share their money with unknown others than chronically rejected adolescents when sharing was not costly. Neuroimaging analyses showed that stably accepted adolescents, compared to chronically rejected adolescents, exhibited higher levels of activation in the temporo‐parietal junction, posterior superior temporal sulcus, temporal pole, pre‐supplementary motor area, and anterior insula during costly sharing decisions. These findings demonstrate that stable peer acceptance across childhood is associated with heightened activity in brain regions previously linked to perspective taking and the detection of social norm violations during adolescence, and thereby provide insight into processes underlying the widely established links between peer acceptance and prosocial behavior.     

Emotional experience in music fosters 18‐month‐olds' emotion–action understanding: a training study

We examine whether emotional experiences induced via music‐making promote infants' use of emotional cues to predict others' action. Fifteen‐month‐olds were randomly assigned to participate in interactive emotion training either with or without musical engagement for three months. Both groups were then re‐tested with two violation‐of‐expectation paradigms respectively assessing their sensitivity to some expressive features in music and understanding of the link between emotion and behaviour in simple action sequences. The infants who had participated in music, but not those who had not, were surprised by music–face inconsistent displays and were able to interpret an agent's action as guided by her expressed emotion. The findings suggest a privileged role of musical experience in prompting infants to form emotional representations, which support their understanding of the association between affective states and action.     

Psychological Empowerment Among Urban Youth: Measurement Model and Associations with Youth Outcomes

Empowerment‐based strategies have become widely used method to address health inequities and promote social change. Few researchers, however, have tested theoretical models of empowerment, including multidimensional, higher‐order models. We test empirically a multidimensional, higher‐order model of psychological empowerment (PE), guided by Zimmerman's conceptual framework including three components of PE: intrapersonal, interactional, and behavioral. We also investigate if PE is associated with positive and negative outcomes among youth. The sample included 367 middle school youth aged 11–16 (M = 12.71; SD = 0.91); 60% female, 32% (n = 117) white youth, 46% (n = 170) African‐American youth, and 22% (n = 80) identifying as mixed race, Asian‐American, Latino, Native American, or other ethnic/racial group; schools reported 61–75% free/reduced lunch students. Our results indicated that each of the latent factors for the three PE components demonstrate a good fit with the data. Our results also indicated that these components loaded on to a higher‐order PE factor (X² = 32.68; df: 22; p = .07; RMSEA: 0.04; 95% CI: .00, .06; CFI: 0.99). We found that the second‐order PE factor was negatively associated with aggressive behavior and positively associated with prosocial engagement. Our results suggest that empowerment‐focused programs would benefit from incorporating components addressing how youth think about themselves in relation to their social contexts (intrapersonal), understanding social and material resources needed to achieve specific goals (interactional), and actions taken to influence outcomes (behavioral). Our results also suggest that integrating the three components and promoting PE may help increase likelihood of positive behaviors (e.g., prosocial involvement); we did not find an association between PE and aggressive behavior. Implications and future directions for empowerment research are discussed.     

Perceptions of coordinated movement

BackgroundHumans are highly social creatures who use others' movements to evaluate their social competencies. Smooth movement specifically signals an attractive, trustworthy or competent person. Those with Developmental Coordination Disorder (DCD), have peer relationship difficulties and lower sociometric preference scores. However, the relationship of perception of poor movement coordination to stereotyping has not been directly demonstrated.AimWe aimed to describe typically developing individuals' social stereotyping of individuals with and without DCD from minimal visual cues.Method3D motion capture tracked the movement of four ‘targets’ (two adult males with DCD and two male controls) in a variety of everyday scenarios. Kinematic footage of the target's movements was presented as a point-light-display to 319 typically developing adults who used The Rating Scale of Social Competence to report perceptions of the target's social competencies.ResultsTargets with DCD were rated as having significantly lower social competence (M = 3.37, SD = 0.93) than controls (M = 3.46, SD = 0.89) t(269) = −5.656; p < 0.001, Cohen's d = 0.34.DiscussionHumans incorporate minimal information on movement fluency to evaluate others' social competencies, including individuals with DCD. Such stereotyping may be automatic and may be an ill-understood mechanism sustaining persistent rejection by peers for individuals with DCD and higher rates of loneliness, isolation and mental disorders. In addition, our study expands research on competence-based stereotyping to a new applied domain, confirming the minimal cues needed to initiate stereotyping of the competencies of others.     

Limits on efficient human mindreading: Convergence across Chinese adults and Semai children

We tested Apperly and Butterfill's (2009, Psychological Review, 116, 753) theory that humans have two mindreading systems whereby the efficient‐system guiding anticipatory glances displays signature limits that do not apply to the flexible system guiding verbal predictions. Experiments 1 and 2 tested urban Mainland‐Chinese adults (n = 64) and Experiment 3 tested Semai children living in the rainforests of Peninsular Malaysia (3‐ to 4‐year‐olds, n = 60). Participants – across different ages, groups and methods – anticipated others’ false‐beliefs about object‐location but not object‐identity. Convergence in signature limits signalled that the early‐developing efficient system involved minimal theory‐of‐mind. Chinese adults and older Semai children showed flexibility in their direct predictions. The flexible mindreading system in ascribing others’ beliefs as such was task‐sensitive and implicated maturational and cultural contributions.     

Trait Mindfulness Predicts Efficient Top‐Down Attention to and Discrimination of Facial Expressions

In social situations, skillful regulation of emotion and behavior depends on efficiently discerning others' emotions. Identifying factors that promote timely and accurate discernment of facial expressions can therefore advance understanding of social emotion regulation and behavior. The present research examined whether trait mindfulness predicts neural and behavioral markers of early top‐down attention to, and efficient discrimination of, socioemotional stimuli. Attention‐based event‐related potentials (ERPs) and behavioral responses were recorded while participants (N = 62; White; 67% female; M_age = 19.09 years, SD = 2.14 years) completed an emotional go/no‐go task involving happy, neutral, and fearful facial expressions. Mindfulness predicted larger (more negative) N100 and N200 ERP amplitudes to both go and no‐go stimuli. Mindfulness also predicted faster response time that was not attributable to a speed‐accuracy trade‐off. Significant relations held after accounting for attentional control or social anxiety. This study adds neurophysiological support for foundational accounts that mindfulness entails moment‐to‐moment attention with lower tendencies toward habitual patterns of responding. Mindfulness may enhance the quality of social behavior in socioemotional contexts by promoting efficient top‐down attention to and discrimination of others' emotions, alongside greater monitoring and inhibition of automatic response tendencies.     

Theory of mind selectively predicts preschoolers’ knowledge‐based selective word learning

Children can selectively attend to various attributes of a model, such as past accuracy or physical strength, to guide their social learning. There is a debate regarding whether a relation exists between theory‐of‐mind skills and selective learning. We hypothesized that high performance on theory‐of‐mind tasks would predict preference for learning new words from accurate informants (an epistemic attribute), but not from physically strong informants (a non‐epistemic attribute). Three‐ and 4‐year‐olds (N = 65) completed two selective learning tasks, and their theory‐of‐mind abilities were assessed. As expected, performance on a theory‐of‐mind battery predicted children's preference to learn from more accurate informants but not from physically stronger informants. Results thus suggest that preschoolers with more advanced theory of mind have a better understanding of knowledge and apply that understanding to guide their selection of informants. This work has important implications for research on children's developing social cognition and early learning.     

The desirability of beliefs: preschoolers' appreciation of fact beliefs and subsequent emotions

In this study, we investigated the extent to which preschool children's own knowledge about reality biases their understanding that others' beliefs about reality govern others' emotions and not reality itself. Therefore, an increasing tension was created between the beliefs of the protagonist and the participant, by providing varying degrees of evidence about the validity of the protagonist's belief. Children of between 4 and 5 years of age were asked to predict the protagonist's emotion, given the protagonist's desire and the protagonist's belief. The results show that, to a certain extent, preschool children take others' beliefs into account when predicting others' emotions. When the outcome is clear, children probably feel tied to reality, and in the case of false beliefs, their knowledge about reality biases their emotion predictions, as was also evident in ‘false belief’ research (Wimmer H, Perner I. 1983. Beliefs about beliefs: representation and constraining function of wrong beliefs in young children's understanding of deception. Cognition 13: 103–128). However, when it is uncertain what the actual outcome will be, then it is not the likelihood of others' beliefs but the desirability of the outcome that biases children's predictions of others' emotions. In other words, when the actual outcome is yet unclear, 4‐ and 5‐year‐olds show a tendency for wishful thinking in their predictions of others' emotions.

One-Year-Olds Warn Others About Negative Action Outcomes

Warning others is a paradigm case of communicative helping and prospective action understanding. The current study addressed the ontogeny of warning in infants' gestural communication. We found that 12- and 18-month-olds (n = 84) spontaneously warned an adult by pointing out to her an aversive object hidden in her way (problem condition). In control conditions, the object was either positive (no-problem condition) or the adult had witnessed its placing (problem-known condition), which resulted in significantly less pointing. Results show that infants intervene spontaneously to help others avoid a problem before it has occurred. These acts of warning entail an understanding of negatively defined goals (to avoid an outcome) and incorrect representations of reality. Findings support theories of altruism and social–pragmatic competencies in infancy.     

Self‐Protective Altruism

Prosocial behavior accentuates the tension between two conflicting human motivations, self‐interest and belongingness. Responding to the needs of others may compromise self‐interest. Acting callously, however, may lead to social disproval. These antagonistic responses are existentially meaningful as belongingness and self‐esteem have been found to regulate death anxiety. In this paper I critically examine three possible hypotheses concerning the tension between egotism and prosociality from a terror management perspective. The first hypothesis, the carpe diem hypothesis, suggests that when death is salient egotistic self‐interest overrides other‐oriented responses. The second hypothesis, the norm salience hypothesis, suggests that when death is salient people will respond according to the momentarily accessible social norm. The third hypothesis, the self‐protective altruism hypothesis, argues that when the prosocial cause reminds people of their fragile, mortal nature people will turn away from helping when death is salient, but when the prosocial cause is benign death salience will increase prosocial responding.     

Bilingualism alters children's frontal lobe functioning for attentional control

Bilingualism is a typical linguistic experience, yet relatively little is known about its impact on children's cognitive and brain development. Theories of bilingualism suggest that early dual‐language acquisition can improve children's cognitive abilities, specifically those relying on frontal lobe functioning. While behavioral findings present much conflicting evidence, little is known about its effects on children's frontal lobe development. Using functional near‐infrared spectroscopy (fNIRS), the findings suggest that Spanish–English bilingual children (n = 13, ages 7–13) had greater activation in left prefrontal cortex during a non‐verbal attentional control task relative to age‐matched English monolinguals. In contrast, monolinguals (n = 14) showed greater right prefrontal activation than bilinguals. The present findings suggest that early bilingualism yields significant changes to the functional organization of children's prefrontal cortex for attentional control and carry implications for understanding how early life experiences impact cognition and brain development.     

The action model of relationship security: How one's own behavior shapes confidence in partners' care,regard, and commitment

The authors present and test the action model of relationship security, which predicts that people's behavior toward a relationship partner shapes their security regarding that partner's care, regard, and commitment. Specifically, actors who enact prosocial or antisocial behavior develop corresponding prosocial or antisocial metaperceptions (i.e., they believe they are viewed as prosocial or antisocial by their partner). In turn, these metaperceptions have a strong influence on actors' security in their partner's care, regard, and commitment due to lay theories positing that prosocial and antisocial behavior impacts others' sentiments. Four studies supported this model. Moreover, findings suggest that prosocial metaperceptions buffer the harmful effects of attachment anxiety on relationship security. This research suggests the relevance of own behavior for relationship security.
