Self-control emerges in a rich sociocultural context. Do group norms around self-control influence the degree to which children use it? We tested this possibility by assigning 3- to 5-year-old ...children to a group and manipulating their beliefs about in-group and out-group behavior on the classic marshmallow task. Across two experiments, children waited longer for two marshmallows when they believed that their in-group waited and their out-group did not, compared with children who believed that their in-group did not wait and their out-group did. Group behavior influenced children to wait more, not less, as indicated by comparisons with children in a control condition who were assigned to a group but received no information about either groups’ delay behavior (Experiment 1). Children also subsequently valued delaying gratification more if their in-group waited and their out-group did not (Experiment 2). Childhood self-control behavior and related developmental outcomes may be shaped by group norms around self-control, which may be an optimal target for interventions.
One simple marshmallow test in preschool children predicts an array of important life outcomes, according to multiple studies spanning several decades. However, a recent conceptual replication casts ...doubt on these famous findings. We conducted an independent, preregistered secondary analysis to test whether previously observed longitudinal associations between preschool delay of gratification and adolescent outcomes would be conceptually replicated. Associations were significant for three of the five outcomes we tested using the analytic approach employed in the original studies of the marshmallow test. Relationships between delay of gratification and problem behavior held in bivariate, multivariate, and multilevel models; in contrast, no significant relationships between delay and problem behavior were found in the other recent replication, even though both studies used the same data set. These relationships were better explained by social support than by self-control, suggesting that the marshmallow test is predictive because it reflects aspects of a child’s early environment that are important over the long term. This novel interpretation of the classic findings points to new directions for intervention.
Young children engage cognitive control reactively in response to events, rather than proactively preparing for events. Such limitations in executive control have been explained in terms of ...fundamental constraints on children's cognitive capacities. Alternatively, young children might be capable of proactive control but differ from older children in their metacognitive decisions regarding when to engage proactive control. We examined these possibilities in three conditions of a task-switching paradigm, varying in whether task cues were available before or after target onset. RTs, ERPs, and pupil dilation showed that 5-year-olds did engage in advance preparation, a critical aspect of proactive control, but only when reactive control was made more difficult, whereas 10-year-olds engaged in proactive control whenever possible. These findings highlight metacognitive processes in children's cognitive control, an understudied aspect of executive control development.

Forming predictions about what will happen next in the world happens early in development, without instruction, and across species. Some environments support more accurate predictions. These more ...predictable environments also support what appear to be positive developmental trajectories, including increases in cognitive control over thoughts and actions. Such consequences of predictable environments have broad-reaching implications for society and have been explained across ecological, psychological, computational, and neural frameworks. However, many challenges remain in understanding the effects of environmental predictability, including adaptive responses to unpredictable environments and the mechanisms underlying the effects of predictable environments on developmental trajectories. Future work addressing different dimensions of predictability—across timescales, locations, actions, people, and outcomes—and their interactions will advance the ability to understand, predict, and support developmental trajectories.
Holding out for a delayed reward in the face of temptation is notoriously difficult, and the ability to do so in childhood predicts diverse indices of life success. Prominent explanations focus on ...the importance of cognitive control. However, delaying gratification may also require trust in people delivering future rewards as promised. Only limited experimental work has tested this idea, and such studies with children were focused on general reward expectations, so evidence was ambiguous as to whether social trust played a role. The present study provides the first targeted test of a role for social trust in children's willingness to delay gratification. Children observed an adult behave in either a trustworthy or untrustworthy manner toward another adult, then were tested in the classic delay of gratification task by that adult. Children were less likely to wait the full delay period, and waited less time overall, for a reward promised by an untrustworthy adult, relative to children tested by a trustworthy adult. These findings demonstrate that manipulations of social trust influence delaying gratification, and highlight intriguing alternative reasons to test for individual differences in delaying gratification and associated life outcomes.
Children's willingness to delay gratification is typically interpreted in terms of cognitive control, but may also require trust in people delivering future rewards as promised. We manipulated preschoolers' impressions of social trust by having them observe an adult either lie or behave honestly with another person, and then measured their willingness to delay gratification for a reward promised by that adult in the classic marshmallow task. Preschoolers waited less time, and were less likely to wait the full 15 min delay period, for rewards that had been promised by an untrustworthy adult relative to a trustworthy adult.
Resisting immediate temptations in favor of larger later rewards predicts academic success, socioemotional competence, and health. These links with delaying gratification appear from early childhood ...and have been explained by cognitive and social factors that help override tendencies toward immediate gratification. However, some tendencies may actually promote delaying gratification. We assessed children’s delaying gratification for different rewards across two cultures that differ in customs around waiting. Consistent with our preregistered prediction, results showed that children in Japan (n = 80) delayed gratification longer for food than for gifts, whereas children in the United States (n = 58) delayed longer for gifts than for food. This interaction may reflect cultural differences: Waiting to eat is emphasized more in Japan than in the United States, whereas waiting to open gifts is emphasized more in the United States than in Japan. These findings suggest that culturally specific habits support delaying gratification, providing a new way to understand why individuals delay gratification and why this behavior predicts life success.
Despite growing interest in improving cognitive abilities across the lifespan through training, the benefits of cognitive training are inconsistent. One powerful contributor may be that individuals ...arrive at interventions with different baseline levels of the cognitive skill being trained. Some evidence suggests poor performers benefit the most from cognitive training, showing compensation for their weak abilities, while other evidence suggests that high performers benefit most, experiencing a magnification of their abilities. Whether training leads to compensation or magnification effects may depend upon the specific cognitive domain being trained (such as executive function or episodic memory) and the training approach implemented (strategy or process). To clarify the association between individual differences in baseline cognitive ability and training gains as well as potential moderators, we conducted a systematic meta-analysis of the correlation between these two variables. We found evidence of a significant meta-correlation demonstrating a compensatory effect, a negative association between initial ability on a trained cognitive process and training gains. Too few papers met our search criteria across the levels of proposed moderators of cognitive domain and training approach to conduct a reliable investigation of their influence over the meta-analytic effect size. We discuss the implications of a compensatory meta-correlation, potential reasons for the paucity of qualifying papers, and important future directions for better understanding how cognitive trainings work and for whom.
The capacity to anticipate and prepare for future events is thought to be critical for cognitive control. Dominant accounts of cognitive control treat the developing system as merely a weaker version ...of the adult system, progressively strengthening over time. Using the AX Continuous Performance Task (AX-CPT) in combination with high-resolution pupillometry, we find that whereas 8-year-old children resemble adults in their proactive use of cognitive control, 3.5-year-old children exhibit a qualitatively different, reactive form of cognitive control, responding to events only as they unfold and retrieving information from memory as needed in the moment. These results demonstrate the need to reconsider the origins of cognitive control and the basis for children's behaviors across domains.
Young adults adaptively coordinate their behavior to avoid demands placed on cognitive control. We investigated how this adaptive coordination develops by having 6–7- and 11–12-year-olds and young ...adults complete a demand selection task, in which participants could select between two tasks that varied in cognitive control demands via differences in rule switch frequency. Adults and older children exhibited significant preference for selecting the less demanding task, as well as a metacognitive signal guiding adaptive demand avoidance behavior across a variety of behavioral and self-report assessments. In contrast, despite evidence of differential demands on cognitive control, younger children did not coordinate their task selections to avoid higher demand. Together, these findings suggest that sensitivity and adaptive responses to control demands emerge with development and are consistent with gradual development of lateral prefrontal cortex, dorsal anterior cingulate cortex, and their functional connectivity, which support effort avoidance in adults.
•Adults and 11–12-year-olds avoided cognitive control demands but 6–7yo did not, despite all ages exhibiting evidence of demand signals.•Adults and 11–12yo but not 6–7yo had subjective awareness of cognitive control demands.•Older children may attend to external cues, such as feedback or accurate performance to ascertain demand differences.•Adults may develop cognitive demand sensitivity from internal effort signals.
