Social interactions come with the fundamental problem of trying to understand others' mental and affective states while under the overpowering influence of one's own concurrent thoughts and feelings. ...The ability to distinguish between simultaneous representations of others' current experiences as well as our own is crucial to navigate our complex social environments successfully. The developmental building blocks of this ability and how this is given rise to by functional and structural brain development remains poorly understood. In this review, I outline some of the key findings on the role of self–other distinction in understanding others' mental as well as emotional states in children and adults. I will begin by clarifying the crucial role for self–other distinction in avoiding egocentric attributions of one's own cognitive as well as affective states to others in adults and outline the underlying neural circuitry in overcoming such egocentricity. This will provide the basis for a discussion of the emergence of self–other distinction in early childhood as well as developmental changes therein throughout childhood and into adulthood. I will demonstrate that self–other distinction of cognitive and emotional states is already dissociable early in development. Concomitantly, I will show that processes of self–other distinction in cognitive and affective domains rely on adjacent but distinct neural circuitry each with unique connectivity profiles, presumably related to the nature of the distinction that needs to be made.
Instances of altruism in children are well documented. However, the underlying mechanisms of such altruistic behavior are still under considerable debate. While some claim that altruistic acts occur ...automatically and spontaneously, others argue that they require behavioral control. This study focuses on the mechanisms that give rise to prosocial decisions such as sharing and costly punishment. In two studies it is shown in 124 children aged 6–9 years that behavioral control plays a critical role for both prosocial decisions and costly punishment. Specifically, the studies assess the influence of taxing aspects of self‐regulation, such as behavioral control (Study 1) and emotion regulation (Study 2) on subsequent decisions in a Dictator and an Ultimatum Game. Further, children's perception of fairness norms and emotional experience were measured. Taxing children's behavioral control prior to making their decisions reduced sharing and costly punishment of unfair offers, without changing perception of fairness norms or the emotional experience. Conversely, taxing children's emotion regulation prior to making their decisions only led to increased experience of anger at seeing unfair offers, but left sharing, costly punishment and the perception of fairness norms unchanged. These findings stress the critical role of behavioral control in prosocial giving and costly punishment in childhood.
This study establishes a functional role for behavioral control in altruistic decisions in childhood. After taxing behavioral control children became less altruistic as indicated by a decrease in sharing and an increase in accepting unfair offers. A control experiment that taxed children’s emotion regulation before making their decision showed no such effect. The results carve out a special role for a specific behavioral control mechanism in altruistic decisions during childhood.

A long-standing question in the behavioral sciences is whether cognitive functions can be improved through dedicated training. It is uncontested that training programs can lead to near transfer, ...meaning increased performance on untrained tasks involving similar cognitive functions. However, whether training also leads to far transfer, meaning increased performance on loosely related untrained tasks or even activities of daily living, is still hotly debated. Here, we review the extant literature and, in particular, the most recent meta-analytic evidence and argue that the ongoing crisis in the field of cognitive-training research may benefit from taking a more mechanistic approach to studying the effectiveness of training. We propose that (a) adopting a more rigorous theoretical framework that builds on a process-based account of training and transfer, (b) considering the role of individual differences in the responsiveness to training, and (c) drawing on Bayesian models of development may help to solve controversial issues in the field and lead the way to designing and implementing more effective training protocols.
Since the discovery that patients with damage to the prefrontal cortex (PFC) show similar deficits in cognitive control as young children, the PFC model of cognitive control development has been a ...popular description of how cognitive control emerges over time. In this review, we show that not only do many studies support this model, but also that more specific models of PFC development can be formulated, according to the functional roles of subregions and by taking into account the distinctions within ventral–dorsal and lateral–medial PFC. We also reveal that the functional development of dorsolateral PFC supports the development of deliberative processes, whereas that of the medial PFC supports the development of internalized decisions. These new conceptualizations may provide better descriptions of the complexity of cognitive control development.
•Priming behavioral control increases subsequent sharing but leaves fairness perception and emotions unchanged.•Priming effects extend over several sharing contexts speaking to a pervasiveness of the ...effect.•Behavioral control plays a key role in altruistic behavior in children.
Young children endorse norms of fairness but rarely act on them. We investigated whether a failure of behavioral control can partially explain why children do not share more generously than they do. We experimentally manipulated behavioral control and observed its effects on sharing in 120 children aged 6–9years of age. Using a between-participants design, we presented children with stories in which a protagonist either exerted behavioral control in an unrelated context or not. Following this, children engaged in a sharing task. We found that children who had been read a story promoting behavioral control shared more than children who had been read a neutral story. This effect held over two different types of instruction. Perceptions of fairness, on the other hand, were identical across conditions. These findings speak to the importance of behavioral control in prosocial behavior, and specifically sharing, during middle childhood.
Human civilization is based on the successful pursuit of long-term goals, requiring the ability to forego immediate pleasure for the sake of larger future rewards. This ability improves with age, but ...the precise cognitive and neural mechanisms underlying its development remain elusive. The developmental changes could result either from younger children valuing immediate rewards more strongly or because older children become better at controlling their impulses. By implementing 2 tasks, a choice-independent valuation task and an intertemporal choice task, both behaviorally and using fMRI in twenty 6- to 13-year old children, we show developmental improvements in behavioral control to uniquely account for age-related changes in temporal discounting. We show further that overcoming temptation during childhood occurs as a function of an age-related increase in functional coupling between value signals in the ventromedial prefrontal cortex and brain regions dedicated to behavioral control, such as left dorsolateral prefrontal cortex during choice. These findings can help to devise measures that reduce the substantial costs of impatience to society.
Human social exchange is often characterized by conflicts of interest requiring strategic behavior for their resolution. To investigate the development of the cognitive and neural mechanisms ...underlying strategic behavior, we studied children's decisions while they played two types of economic exchange games with differing demands of strategic behavior. We show an increase of strategic behavior with age, which could not be explained by age-related changes in social preferences but instead by developmental differences in impulsivity and associated brain functions of the left dorsolateral prefrontal cortex (DLPFC). Furthermore, observed differences in cortical thickness of lDLPFC were predictive of differences in impulsivity and strategic behavior irrespective of age. We conclude that egoistic behavior in younger children is not caused by a lack of understanding right or wrong, but by the inability to implement behavioral control when tempted to act selfishly; a function relying on brain regions maturing only late in ontogeny.
► Age-related increases in strategic behavior correlate with greater impulse control ► Development of DLPFC function subserves impulse control needed for strategic behavior ► Age-independent DLPFC thickness predicts individual differences in strategic behavior
How does social behavior develop? Steinbeis et al. show that egotistical social decisions during early childhood are not caused by a lack of understanding right or wrong but by a failure in impulse control due to delayed maturation and functional development of the prefrontal cortex.
Recent studies have shown that music is capable of conveying semantically meaningful concepts. Several questions have subsequently arisen particularly with regard to the precise mechanisms underlying ...the communication of musical meaning as well as the role of specific musical features. The present article reports three studies investigating the role of affect expressed by various musical features in priming subsequent word processing at the semantic level. By means of an affective priming paradigm, it was shown that both musically trained and untrained participants evaluated emotional words congruous to the affect expressed by a preceding chord faster than words incongruous to the preceding chord. This behavioral effect was accompanied by an N400, an ERP typically linked with semantic processing, which was specifically modulated by the (mis)match between the prime and the target. This finding was shown for the musical parameter of consonance/dissonance (Experiment 1) and then extended to mode (major/minor) (Experiment 2) and timbre (Experiment 3). Seeing that the N400 is taken to reflect the processing of meaning, the present findings suggest that the emotional expression of single musical features is understood by listeners as such and is probably processed on a level akin to other affective communications (i.e., prosody or vocalizations) because it interferes with subsequent semantic processing. There were no group differences, suggesting that musical expertise does not have an influence on the processing of emotional expression in music and its semantic connotations.
•This is the first study to investigate the development of response inhibition focussing on variability.•We examined intraindividual variability both in stopping latencies and the underlying neural ...circuitry.•There were no developmental differences in mean response inhibition, yet clear differences in performance variability.•This, in turn, was associated with developmental differences in brain signal variability.•Behavioral and neural variability indices might be a more sensitive measure of developmental differences in inhibition.
Research on the development of response inhibition in humans has focused almost exclusively on average stopping performance. The development of intra-individual variability in stopping performance and its underlying neural circuitry has remained largely unstudied, even though understanding variability is of core importance for understanding development. In a total sample of 45 participants (19 children aged 10–12 years and 26 adults aged 18–26 years) of either sex we aimed to identify age-related changes in intra-individual response inhibition performance and its underlying brain signal variability. While there was no difference in average stopping performance between children and adults, stop signal latencies for the children were more variable. Further, brain signal variability during successful stopping was significantly higher in adults compared to children, especially in bilateral thalamus, but also across regions of the inhibition network. Finally, brain signal variability was significantly associated with stopping performance behavioral variability in adults. Together these results indicate that variability in stopping performance decreases, whereas neural variability in the inhibition network increases, from childhood to adulthood. Future work will need to assess whether developmental changes in neural variability drive those in behavioral variability. In sum, both, neural and behavioral variability indices might be a more sensitive measure of developmental differences in response inhibition compared to the standard average-based measurements.
Autism spectrum disorder (ASD) shows deficits in self-other distinction during theory of mind (ToM). Here we investigated whether ASD patients also show difficulties in self-other distinction during ...empathy and if potential deficits are linked to dysfunctional resting-state connectivity patterns. In a first study, ASD patients and controls performed an emotional egocentricity paradigm and a ToM task. In the second study, resting-state connectivity of right temporo-parietal junction and right supramarginal gyrus (rSMG) were analysed using a large-scale fMRI data set. ASD patients exhibited deficient ToM but normal emotional egocentricity, which was paralleled by reduced connectivity of regions of the ToM network and unimpaired rSMG network connectivity. These results suggest spared self-other distinction during empathy and an intact rSMG network in ASD.
