Associations of observed callous-unemotional behaviors in early childhood with conduct problems and substance use over 14 years

Callous-unemotional (CU) behaviors (i.e., low concern and active disregard for others) uniquely predict severe conduct problems and substance use when present by late childhood. Less is known about the predictive utility of CU behaviors displayed in early childhood, when morality is developing and interventions may be more effective. Children aged 4-7 years (N = 246; 47.6% girls) completed an observational task wherein they were encouraged to tear an experimenter's valued photograph, and blind raters coded children's displayed CU behaviors. During the next 14 years, children's conduct problems (i.e., oppositional defiant and conduct symptoms) and age of onset of substance use were assessed. Compared to children displaying fewer CU behaviors, children displaying greater CU behaviors were 7.61 times more likely to meet criteria for a conduct disorder (n = 52) into early adulthood (95% CI, 2.96-19.59; p = <.0001), and their conduct problems were significantly more severe. Greater CU behaviors were associated with earlier onset of substance use (B = -.69, SE = .32, t = -2.14, p = .036). An ecologically valid observed indicator of early CU behavior was associated with substantially heightened risk for conduct problems and earlier onset substance use into adulthood. Early CU behavior is a powerful risk marker identifiable using a simple behavioral task which could be used to target children for early intervention.

Bridging the gap between emotion and joint action

Our daily human life is filled with a myriad of joint action moments, be it children playing, adults working together (i.e., team sports), or strangers navigating through a crowd. Joint action brings individuals (and embodiment of their emotions) together, in space and in time. Yet little is known about how individual emotions propagate through embodied presence in a group, and how joint action changes individual emotion. In fact, the multi-agent component is largely missing from neuroscience-based approaches to emotion, and reversely joint action research has not found a way yet to include emotion as one of the key parameters to model socio-motor interaction. In this review, we first identify the gap and then stockpile evidence showing strong entanglement between emotion and acting together from various branches of sciences. We propose an integrative approach to bridge the gap, highlight five research avenues to do so in behavioral neuroscience and digital sciences, and address some of the key challenges in the area faced by modern societies.

Reparative Prosocial Behavior Difficulties across Childhood Predict Poorer Social Functioning and Depression in Adolescence

Difficulty using reparative behaviors (i.e., prosocial behaviors that individuals use after they have transgressed to cause another's distress) has been concurrently associated with poorer social functioning and both internalizing and externalizing disorders in children and adults. Despite these associations, no study has examined social and psychological outcomes of children who display consistently low levels of reparative behaviors across childhood. This study used established developmental trajectories of reparative behaviors that span preschool through early adolescence (low-stable, moderate-stable, and high-stable) to predict social and psychological outcomes in adolescence (N = 129). Membership in trajectories characterized by lower levels of reparative behaviors predicted greater social rejection, social withdrawal, aggression, and symptoms of depression in adolescence, even when controlling for baseline levels of each outcome. Membership in the low-stable reparative trajectory also significantly mediated the relationship between high levels of guilt in preschool and greater depression severity in adolescence. Findings suggest that children who display persistently low levels of reparative behaviors may be at-risk for a variety of poorer social and emotional outcomes. Further, preschoolers who display both high levels of guilt and low levels of reparative behaviors may be at particularly high risk for depression recurrence in adolescence. Thus, interventions that teach young children reparative skills and/or promote approach rather than avoidance after transgressions may have important implications for preventing a wide range of poorer social and emotional outcomes in adolescence.
