Identifying the underpinnings of mathematics proficiency is relevant for all societies. A growing literature supports a relation between executive function (EF) and mathematics across a wide age range, but causal links are not well understood. In the current study, typically developing preschool children (N = 104) were randomly assigned to one of four training conditions: EF, Number, EF + Number, or an active Control. They participated in three brief training sessions and pretest and posttest sessions measuring EF and mathematics skills. EF training improved EF skills on a task similar to the training but did not extend to an untrained EF task. In addition, the EF training improved number skills but not general mathematics skills. The EF + Number training improved number and general mathematics skills but not EF skills. The EF + Number training did not yield significantly greater benefits for EF and mathematics beyond other training conditions. Finally, differential training effects emerged, such that children with lower pretest EF skills had greater EF benefits on only the trained EF skill. In addition, children from lower versus higher socioeconomic households had greater gains in numerical skills following EF training. No training condition improved verbal knowledge, suggesting that results were specific to the targeted skills. These results extend prior findings on the effectiveness of improving EF and mathematical skills through short-term trainings during early childhood., (Copyright © 2023 Elsevier Inc.

Self-distancing (i.e., creating mental distance between the self and a stimulus by adopting a less egocentric perspective) has been studied as a way to improve adolescents' and adults' emotion regulation. These studies instruct adolescents and adults to use visual imagery or language to create distance from the self before engaging in self-regulation tasks and when thinking about past and future events. For example, adults are asked to recall past, negative emotional experiences from either a first-person perspective (no distance) or a third-person perspective (self-distanced). These studies show that a self-distanced perspective allows adults to cope more adaptively when recalling negative feelings. However, the self-distancing paradigm used with adults was not developmentally appropriate for young children. This modified self-distancing paradigm involves instructing children to think about their thoughts, feelings, and actions from different perspectives that vary in their distance from the self while completing a self-regulation task. The paradigm involves randomly assigning children to use one of three perspectives: self-immersed, third-person, or exemplar. In the self-immersed condition, children are asked to think about themselves using the first-person perspective (e.g., "How am I feeling?") and no distance is created from the self. In the third-person condition, children are asked to create distance from the self by using the third-person perspective (e.g., "How is [child's name] feeling?"). In the exemplar condition, the greatest distance from the self is created by asking children to pretend to be a media character and to think about that character's thoughts and feelings (e.g., "How is Batman feeling?"). Studies using the self-distancing paradigm with 4-6-year-olds have found that as the amount of distance from the self increases (self-immersed < third-person < exemplar), children perform better on self-regulation tasks. These findings suggest that the strategies implemented in the self-distancing protocol may be useful to include in self-regulation interventions for young children.

Self-distancing has been shown to improve children's self-regulation in a variety of tasks. However, it is unknown whether this strategy is more effective for some children than others. This study investigated self-distancing in relation to individual differences in executive function (EF) and effortful control (EC). Typically developing 4- (n = 72) and 6-year-olds (n = 67) were randomly assigned to think about the self from one of four perspectives: self-immersed, control, third-person, or competent media character. Children participated in a frustrating task for up to 10 min and overt expressions of frustration were coded. Conceptually replicating prior research with adults, younger children, and children with lower EF and lower EC (independent of age) benefitted the most from self-distancing. This suggests self-distancing is especially effective during a frustrating task for children with less developed self-control, adding to a growing body of research showing self-distancing is especially effective for vulnerable individuals. Statement of contribution What is already known on this subject? Using third-person speech and pretending to be a media character improve children's self-regulation. Age and theory of mind skills are related to the effectiveness of self-distancing. What does this study add? Self-distancing can help children regulate their emotions during an emotionally charged task. Individual differences in executive function and effortful control are related to the efficacy of self-distancing., (© 2018 The British Psychological Society.)

This study investigated the benefits of self-distancing (i.e., taking an outsider's view of one's own situation) on young children's perseverance. Four- and 6-year-old children (N = 180) were asked to complete a repetitive task for 10 min while having the option to take breaks by playing an extremely attractive video game. Six-year-olds persevered longer than 4-year-olds. Nonetheless, across both ages, children who impersonated an exemplar other-in this case a character, such as Batman-spent the most time working, followed by children who took a third-person perspective on the self, or finally, a first-person perspective. Alternative explanations, implications, and future research directions are discussed., (© 2016 The Authors. Child Development © 2016 Society for Research in Child Development, Inc.)

Executive function (EF) has been highlighted as a potentially important factor for mathematical understanding. The relation has been well established in school-aged children but has been less explored at younger ages. The current study investigated the relation between EF and mathematics in preschool-aged children. Participants were 142 typically developing 3- and 4-year-olds. Controlling for verbal ability, a significant positive correlation was found between EF and general math abilities in this age group. Importantly, we further examined this relation causally by varying the EF load on a magnitude comparison task. Results suggested a developmental pattern where 3-year-olds' performance on the magnitude comparison task was worst when EF was taxed the most. Conversely, 4-year-olds performed well on the magnitude task despite varying EF demands, suggesting that EF might play a critical role in the development of math concepts., (Copyright © 2016 Elsevier Inc.
