Machiavellianism is an antisocial interpersonal style involving the use of manipulative, deceptive, and coercive behaviors in the pursuit of self-interest. Although widely studied as a "dark" personality trait in adults, relatively little is known about the developmental correlates of Machiavellian tendencies earlier in life. The present study addressed this knowledge gap by examining associations between Machiavellian behavior and three theoretically relevant social-emotional domains-prosocial emotions, emotion recognition skills, and self-control-in a community sample of 7- and 11-year-old Canadian children ( N = 300, 50% female). Of particular interest was the extent to which individual differences in social-emotional capacities were uniquely associated with Machiavellian behavior after controlling for aggression, a relatively well-studied antisocial behavior in childhood. Parents reported on children's Machiavellian behavior and aggression. Social-emotional correlates were assessed via parent and child reports, behavioral tasks, and physiological assessments. Machiavellian behavior and aggression were similarly associated with lower parent-reported prosocial emotions and self-control. Machiavellian (but not aggressive) behavior was associated with lower child-reported guilt (a prosocial emotion), higher resting skin conductance levels (reflecting a general tendency for higher arousal), and better anger recognition. Semipartial correlational analyses indicated that these patterns of association with Machiavellian behaviors held independent of aggression. These findings indicate that, by middle childhood, Machiavellian behavior constitutes a distinct form of antisocial conduct that is associated with a unique social-emotional risk profile.

Extant research on physiological dysregulation in children has focused on point-in-time measures and absolute mean levels of physiology. However, these methods do not capture dynamic fluctuations in physiology that characterize dysregulation. In the present work, we aimed to assess whether physiological dysregulation as captured by fluctuations rather than mean levels would differentiate between children with and without clinically elevated levels of externalizing behavior. As an exploratory approach, we examined fluctuations in children's physiological responses (i.e., root mean square of successive differences [RMSSD] in beat-to-beat heart rate intervals) to social transgression scenarios across 15 short-term measurement occasions (5-second bins). Controlling for mean RMSSD, as well as emotional and cognitive correlates of externalizing behavior (i.e., sympathy and inhibitory control), children with externalizing difficulties exhibited greater within-person fluctuations in RMSSD (i.e., physiological dysregulation) compared to children without externalizing difficulties. The present findings provide preliminary support for using intensive longitudinal data comprised of short-term physiological measurements and point to the centrality of within-child physiological variability as a marker of dysregulation, particularly amongst children with externalizing disorders for whom self-regulation is a core challenge., (© 2023.

This study examined the course and correlates of the happy victimizer tendency-the expectation that harming others to achieve a goal will result in positive emotional outcomes for the transgressor-from 4 to 6 years of age in a community sample of Canadian children ( N = 150; 50% female; Time 1 M age = 4.53 years, SD = .30; 33% European background). At each time point, we conducted semistructured interviews with children to assess their emotion expectancies and reasoning in response to hypothetical acts of aggression. Caregivers (84% mothers; 91% college diploma or higher; 41% yearly household income ≥$125,000 CAD [approximately $90,500 USD]) provided ratings of children's inhibitory control and sympathy at study onset. Most 4-year-old children expected to feel good after victimizing others, but this tendency declined through age 6. Children higher in sympathy were less likely to happy victimize at age 4, whereas greater inhibitory control predicted faster decreases in happy victimizing over time.

With a sample of 4- and 8-year-olds (N = 131), we tested the extent to which more frequent experiences of victimization were associated with heightened aggression towards others, and how sympathetic concern and resting respiratory sinus arrhythmia (RSA) factored into this relationship. Caregivers reported their children's aggression and sympathy. Children reported their victimization and their resting RSA was calculated from electrocardiogram data in response to a nondescript video. Findings revealed that children who reported more frequent victimization were rated as less sympathetic and, in turn, more aggressive. However, resting RSA moderated this path, such that children with high levels were rated as more versus less sympathetic when they reported less versus more victimization, respectively. Results suggest that considering children's sympathetic tendencies and physiology is important to gain a nuanced understanding of their victimization-related aggression.

Although emotionally well-regulated children are more likely to behave prosocially, the psychological processes that connect their emotion regulation abilities and prosocial behavior are less clear. We tested if other-oriented sympathy and trust mediated the links between emotion regulation capacities (i.e., resting respiratory sinus arrhythmia [RSA], negative emotional intensity, and sadness regulation) and prosocial behavior in an ethnically diverse sample of 4- and 8-year-olds (N = 131; 49% girls). Resting RSA was calculated from children's electrocardiogram data in response to a nondescript video. Sympathy was child and caregiver reported, whereas negative emotional intensity, sadness regulation, trust, and prosocial behavior were caregiver reported. Regardless of age, higher resting RSA was linked to higher sympathy, which was associated with higher prosocial behavior. The positive link between sadness regulation and prosocial behavior was mediated by higher sympathy and trust. Children's other-oriented psychological processes may play important roles in translating certain emotion regulation capacities into prosocial behavior.

This study examined the development of children's decisions, reasoning, and emotions in contexts of peer inclusion/exclusion. We asked an ethnically diverse sample of 117 children aged 4years (n=59; 60% girls) and 8years (n=58; 49% girls) to choose between including hypothetical peers of the same or opposite gender and with or without attention deficit/hyperactivity problems and aggressive behavior. Children also provided justifications for, and emotions associated with, their inclusion decisions. Both 4- and 8-year-olds predominantly chose to include the in-group peer (i.e., the same-gender peer and peers without behavior problems), thereby demonstrating a normative in-group inclusive bias. Nevertheless, children included the out-group peer more in the gender context than in the behavior problem contexts. The majority of children reported group functioning-related, group identity-related, and stereotype-related reasoning after their in-group inclusion decisions, and they associated happy feelings with such decisions. Although most children attributed sadness to the excluded out-group peer, they attributed more anger to the excluded out-group peer in the aggression context compared with other contexts. We discuss the implications of our findings for current theorizing about children's social-cognitive and emotional development in contexts of peer inclusion and exclusion., (Copyright © 2017 Elsevier Inc.

Heightened attention to sociomoral conflicts and arousal at the prospect of committing moral transgressions are thought to increase the likelihood of negatively valenced moral emotions (NVMEs; e.g., guilt) in children. Here, we tested this biphasic model of moral emotions with a psychophysiological framework. For a series of vignettes depicting moral transgressions, 5- and 8-year-olds (N=138) were asked to anticipate their emotions as hypothetical victimizers. Their responses were coded for the presence and intensity of NVMEs. In addition, their heart rate (HR) was calculated for three intervals of interest: a baseline period, the presentation of vignettes, and the anticipation of emotions following vignettes. We used multilevel modeling to examine how change in children's HR across these intervals related to the intensity of their NVMEs. Those who experienced greater HR deceleration from baseline to vignettes and greater acceleration from vignettes to anticipated emotions reported more intense NVMEs. We discuss the potential attention- and arousal-related processes behind children's physiological reactivity and anticipated emotions in contexts of moral transgression., (Copyright © 2015 Elsevier Inc.

This study examined links between inhibitory control, moral emotions (sympathy and guilt), and reparative behavior in an ethnically diverse sample of 4- and 8-year-olds (N = 162). Caregivers reported their children's reparative behavior, inhibitory control, and moral emotions through a questionnaire, and children reported their guilt feelings in response to a series of vignettes depicting moral transgressions. A hypothesized meditation model was tested with inhibitory control relating to reparative behavior through sympathy and guilt. In support of this model, results revealed that high levels of inhibitory control were associated with high levels of reparative behavior through high levels of sympathy and guilt. However, the mediation of inhibitory control to reparation through guilt was significant for 4-year-olds only. Results are discussed in relation to the temperamental, regulatory, and affective-moral precursors of reparative behavior in early and middle childhood.

Adolescents' emotions in the context of moral decision-making repeatedly have been shown to predict actual behaviour. However, little systematic information on developmental change regarding these emotion expectancies has been available thus far. This longitudinal study investigated anticipated moral emotions and decision-making between the ages of 15 and 21 in a representative sample of Swiss adolescents (N = 1,258; 54 % female; M = 15.30 years). Anticipated moral emotions and decision-making were assessed through a semi-structured interview procedure. Using Bernoulli hierarchical linear modeling, it was found that positive feelings after a moral transgression (i.e., "happy victimizer" responses) decreased over time, whereas positive feelings after a moral decision (i.e., "happy moralist" responses) increased. However, this pattern was contingent upon the moral scenario presented. Systematic relationships between anticipated moral emotions and moral personality characteristics of sympathy, conscientiousness, and agreeableness were found, even when controlling for socio-demographic characteristics and cognitive ability. Overall, this study demonstrates that the development of anticipated moral emotions is not limited to childhood. Furthermore, our findings suggest that moral emotions serve as an important link between moral personality development and decision-making processes that are more proximal to everyday moral behavior.

This article explores how adolescents feel and think about contexts of moral conflict and social exclusion. We asked twelve-year-old adolescents how they would feel about intentionally harming another peer, omitting a prosocial duty, and excluding another peer. We then asked them to explain the reasoning behind their feelings and report on levels of sympathy. In all contexts, adolescents anticipated a variety of negative emotions for reasons of fairness and empathy. However, more feelings of guilt were reported in contexts of intentional harm than in other contexts. Adolescents with high levels of sympathy reported more guilt, for reasons of fairness and empathy, than adolescents with low levels of sympathy. These findings provide a window into adolescents' emotions and reasoning regarding moral and social issues., (Copyright © 2013 Wiley Periodicals, Inc., A Wiley Company.)

Emotion recognition and emotion regulation have been implicated as promising correlates of sympathy. However, their relative and joint contributions to sympathy in different periods of childhood remain unclear. Moreover, researchers have not explored the relative importance of recognizing and regulating distinct distress‐related emotions, such as sadness and anger, for sympathy. The objective of the current paper was to gain a deeper understanding of which underlying emotion‐related factors are most implicated in sympathy and when in childhood they are most predictive. With an ethnically diverse sample of 4‐ and 8‐yearolds (N = 300, n = 150 in each age group; 50% female), this study tested sadness and anger recognition and regulation, and interactions thereof, as predictors of sympathy. Better sadness and anger regulation independently predicted higher levels of sympathy in 4‐ and 8‐year‐olds, albeit sadness regulation was a more robust predictor of sympathy in 4‐year‐olds. Better sadness recognition was associated with higher sympathy in 8‐year‐olds who also had better sadness regulation. Results underscore the importance of emotion regulation for sympathy, particularly in early childhood. The findings also tentatively suggest that the correlates of sympathy may become more nuanced in middle childhood, with emotion‐specific recognition and regulation capacities employed in concert.

Lacking the capacity for guilt is a defining characteristic of callous-unemotional (CU) traits. Although guilt is a multifaceted construct, past CU research has rarely considered the reasons underlying children's negative emotional responses to wrongdoing. The present study investigated how different forms of guilt were associated with CU traits during early and middle childhood in a Canadian community sample. We interviewed 4- and 8-year-olds (N = 300; 50% female) to assess their emotion attributions and reasoning in response to hypothetical acts of aggression. Interview responses were used to calculate variables representing undifferentiated, ethical, and non-ethical guilt ratings. Caregivers rated children's CU tendencies at baseline and again 3 years later. Higher ethical guilt was associated with lower CU scores concurrently and 3 years later. Higher non-ethical guilt was associated with higher CU scores at baseline (for older children) and 3 years later (for all children). Undifferentiated guilt was not associated with CU after controlling for demographic variables. [ABSTRACT FROM AUTHOR]

Digital natives (i.e., those who have grown up in the digital age) are likely to receive emotional support through digital means, such as texting and video calling. However, virtually all studies assessing the benefits of emotional support have focused on in-person support; the relative efficacy of digital support remains unclear. This study assessed a sample of young adults’ negative emotions, digital and in-person support for those emotions, and success in regulating them 3 times per day for 14 days (N = 164; 6,530 collective measurement occasions). Participants’ social surroundings at the time of each negative emotion and trait levels of social avoidance were also considered. Digital support was expected to be received more often and perceived as more effective for regulating negative emotions when participants were alone and higher in social avoidance. However, with the exception of those higher in social avoidance receiving less digital (and in-person) support, digital support was received and perceived as effective regardless of these factors, and its perceived effectiveness was on par with that of in-person support. For digital natives, digital support may be just as effective as the “real thing” and its benefits may not be restricted to isolated or socially avoidant users. Findings are discussed in relation to the emotional consequences and social constraints of the COVID-19 pandemic. If transcending the time and space limitations of in-person support with digital support is the new norm, the good news is that it seems to be working. [ABSTRACT FROM AUTHOR]

Proactive and reactive aggression subtypes are distinguishable as early as the preschool years. However, their early physiological and social–emotional correlates have not been examined simultaneously. We tested whether children's skin conductance level, anger regulation, and trust in others were differentially related to their proactive and reactive aggression. Four‐year‐olds and their primary caregivers were recruited from a large Canadian city (N = 150). Controlling for reactive aggression, higher trust was associated with lower proactive aggression, but only for children with low anger regulation or skin conductance level. Controlling for proactive aggression, lower anger regulation was related to higher reactive aggression, and higher trust was related to higher reactive aggression for children with high skin conductance level. Findings highlight the unique and collective relations of physiology, emotion regulation, and trust to different forms of aggression in early childhood. Statement of contributionWhat is already known on this subjectProactive and reactive aggression subtypes are distinguishable as early as the preschool years.Unique physiological and social–emotional correlates of each subtype have been studied in middle and late childhood.Trust is a critical milestone for positive social interactions in early childhood and has been linked to aggression.What the present study addsPhysiological and social–emotional correlates are uniquely linked to subtypes of aggression already at age 4.Trust is differentially linked to aggression subtypes as a function of anger regulation and skin conductance level.

Economically disadvantaged children often lack the resources to purchase popular goods and participate in their preferred social groups' activities, making it difficult to fit in. Meanwhile, children from middle socioeconomic status (SES) families may have additional influence over whether low SES children are included in such groups. We examined how a middle SES sample of 333 4- and 8-year-olds felt and reasoned about excluding a child who is economically disadvantaged (i.e., a needy child) versus a child who attends another school (i.e., a less needy child). We also examined whether children's dispositional sympathy was associated with their negatively valenced moral emotions (NVMEs) after hypothetically excluding. Older children reported feeling more NVMEs for both targets of exclusion. Furthermore, unlike 4-year-olds, 8-year-olds differentiated between the targets of exclusion by reporting more NVMEs after excluding a child who is economically disadvantaged. Lastly, children's sympathy was positively associated with their NVMEs after excluding a child who is economically disadvantaged but not a child who attends another school. We conclude that with increasing sympathy and age, children likely become more sensitive to the needs of their disadvantaged peers--an effect with meaningful implications for improving peer relationships across socioeconomic spheres.
