Early therapeutic interventions may assist couples in modifying activities, behaviors, and expectations about the future of the relationship. Such modifications may help maintain relationship satisfaction, decrease burden, preserve quality of life, and delay time-to-placement. Extending time-to-placement could have cost savings implications for families and the healthcare system.

Little is known about the mechanisms underlying a ubiquitous behavior in preschoolers, help-seeking. We tested the hypothesis that preschoolers' awareness of their own uncertainty is associated with help-seeking. Three-, 4-, and 5-year-olds (N = 125) completed a perceptual identification task twice: once independently and once when they could request help from a confederate whose competence level was manipulated. Consistent with our hypothesis, participants sought help more frequently on trials for which, when required to answer independently, they expressed lower confidence. Children in the bad-helper condition were slower to respond after receiving help than those in the good-helper condition. Finally, females and children with more advanced theory of mind were more likely to seek help, identifying additional factors that relate to help-seeking.

The ability to experience uncertainty (i.e., uncertainty monitoring) is an important skill that enables us to optimize our performance by acting cautiously or seeking additional information when we feel uncertain, and by expressing our knowledge when we feel certain (i.e., uncertainty control). Research reveals that even young preschoolers can introspect on uncertainty and act appropriately based on these introspections. We conclude that uncertainty monitoring and control can be driving forces of cognitive development during the preschool years. In this article, we review the emerging literature on this topic, highlight open questions, and draw connections with other research domains.

Episodic memory improves during childhood and this improvement has been associated with age differences in hippocampal function, but previous research has not manipulated the possible underlying mechanisms. We tested the hypothesis that age-related differences in hippocampal activation may reflect changes in retrieval flexibility. We expected these activation differences to be observed most prominently in the anterior hippocampus. Functional magnetic resonance imaging (fMRI) data were collected from children ages 8 and 10, and adults (N = 63) during an associative recognition task that required participants to recognize pairs of pictures which either appeared in the same location as during encoding (Same location), or in a flipped location, such that each picture switched their location with the other member of the pair (Flipped location). Recognition of same-location pairs placed lower demands on flexible retrieval compared to recognition of flipped-location pairs. Behaviorally, 8-year-olds exhibited the strongest correct recognition gains for same-location compared to flipped-location pairs, and females unexpectedly outperformed males across all ages. When we examined correct recognition, adults recruited the hippocampal head more strongly for flipped- versus same-location pairs compared to both groups of children; in contrast both adults and 10-year-olds recruited the hippocampal tail more strongly for flipped- versus same-location pairs compared to 8-year-olds. This pattern was stronger in the left hippocampus and for females. Moreover hippocampal discrimination between recognized and forgotten items in the same-location condition was stronger in 8-year-olds compared to adults, and was stronger in the flipped-location condition in adults compared to 8-year-olds; this pattern was stronger in the left hippocampus. Individual differences in this discrimination contrast for flipped-location trials in the head and body predicted performance on an index of creative thinking. Overall, these results lend new support to the idea that hippocampal development may reflect change in retrieval flexibility with implications for additional forms of flexible cognition.

Schemas capture patterns across multiple experiences, accumulating information about common event structures that guide decision making in new contexts. Schemas are an important principle of leading theories of cognitive development; yet, we know little about how children and adolescents form schemas and use schematic knowledge to guide decisions. Here, we show that the ability to acquire schematic knowledge based on the temporal regularities of events increases during childhood and adolescence. Furthermore, we show that temporally mediated schematic knowledge biases reasoning decisions in an age-dependent manner. Participants with greater temporal schematic knowledge were more likely to infer that temporally related items shared other, nontemporal properties, with adults showing the greatest relationship between schema knowledge and reasoning choices. These data indicate that the mechanisms underlying schema formation and expression are not fully developed until adulthood and may reflect the ongoing maturation of hippocampus and prefrontal cortex through adolescence.

Episodic prospection is the mental simulation of a personal future event in rich contextual detail. This study examined age-related differences in episodic prospection in 5- to 11-year-olds and adults (N = 157), as well as factors that may contribute to developmental improvements. Participants' narratives of past, future, and make-believe events were coded for episodic content, and self-concept coherence (i.e., how coherently an individual sees himself or herself) and narrative ability were tested as predictors of episodic prospection. Although all ages provided less episodic content for future event narratives, age-related improvements were observed across childhood, suggesting future event generation is particularly difficult for children. Self-concept coherence and narrative ability each independently predicted the episodic content of 5- and 7-year-olds' future event narratives.

Episodic prospection is the ability to mentally simulate personal future events that are rich in contextual detail and plausible for the individual. It therefore incorporates episodic information (who, what, where, and when of a particular event), as well as details about one's self (e.g., knowledge, goals, motivations and desires). The ability to mentally simulate personal future events is thought to serve an adaptive purpose as it allows the individual to plan actions that align with his or her future goals and challenges. This review seeks to integrate research exploring how changes in episodic memory and self‐concept, and their associated neural mechanisms, contribute to the development of episodic prospection between childhood and adolescence. Elucidating the mechanisms contributing to this development is critical for understanding its potential influence on learning, goal achievement, and pedagogy between childhood and adolescence.
