Children's confidence on mathematical equivalence and fraction problems.

Metacognition is how people think about their own thinking, and it includes children's confidence in their problem-solving solutions. We assessed children's metacognition in two areas of mathematics that are often plagued by misconceptions and often studied separately-mathematical equivalence (e.g., 3 + 4 = 5 +__) and fraction magnitude (e.g., 1/3 = 2/__). Specifically, we quantified children's metacognitive skills across these topics, examined whether these skills are topic-specific, and determined how these skills covary with domain-general executive functioning. A total of 80 elementary school children (Mage = 7.70 years, SD = 0.69) provided trial-by-trial performance data and confidence judgments on equivalence and fraction problems as well as assessments of executive function. Children's metacognitive skills were especially impaired when using incorrect strategies based on misconceptions, and we did not find robust evidence for cross-topic associations. We found modest associations between children's metacognitive skills and their working memory and inhibitory control. Findings have theoretical and practical implications for understanding which children struggle with these important mathematics concepts and why.

Links between repeating and growing pattern knowledge and math outcomes in children and adults.

This study examined repeating and growing pattern knowledge and their associations with procedural and conceptual arithmetic knowledge in a sample of U.S. children (N = 185; Mage  = 79.5 months; 55% female; 88% White) and adults (N = 93; Mage  = 19.5 years; 62% female; 66% White) from 2019 to 2020. Three key findings emerged: (1) repeating pattern tasks were easier than growing pattern tasks, (2) repeating pattern knowledge robustly predicted procedural calculation skills over and above growing pattern knowledge and covariates, and (3) growing pattern knowledge modestly predicted procedural and conceptual math outcomes over and above repeating pattern knowledge and covariates. We expand existing theoretical models to incorporate these specific links and discuss implications for supporting math knowledge.

Children's confidence using incorrect strategies on mathematical equivalence problems.

Children often struggle to solve mathematical equivalence problems correctly. The change-resistance theory offers an explanation for children's difficulties and suggests that some incorrect strategies represent the overgeneralization of children's narrow arithmetic experience. The current research considered children's metacognitive abilities to test a tacit assumption of the change-resistance theory by providing a novel empirical examination of children's strategy use and certainty ratings. Children were recruited from U.S. elementary school classrooms serving predominantly White students between the ages of 6 and 9. In Study 1 (n = 52) and Study 2 (n = 147), children were more certain that they were correct when they employed arithmetic-specific incorrect strategies relative to other incorrect strategies. These findings are consistent with the change-resistance theory and have implications for the development of children's metacognition.

Individual differences in executive function and learning: The role of knowledge type and conflict with prior knowledge.

Executive function (EF) predicts children's academic achievement; however, less is known about the relation between EF and the actual learning process. The current study examined how aspects of the material to be learned-the type of information and the amount of conflict between the content to be learned and children's prior knowledge-influence the relation between individual differences in EF and learning. Typically developing 4-year-olds (N = 61) completed a battery of EF tasks and several animal learning tasks that varied on the type of information being learned (factual vs. conceptual) and the amount of conflict with the learners' prior knowledge (no prior knowledge vs. no conflicting prior knowledge vs. conflicting prior knowledge). Individual differences in EF predicted children's overall learning, controlling for age, verbal IQ, and prior knowledge. Children's working memory and cognitive flexibility skills predicted their conceptual learning, whereas children's inhibitory control skills predicted their factual learning. In addition, individual differences in EF mattered more for children's learning of information that conflicted with their prior knowledge. These findings suggest that there may be differential relations between EF and learning depending on whether factual or conceptual information is being taught and the degree of conceptual change that is required. A better understanding of these different relations serves as an essential foundation for future research designed to create more effective academic interventions to optimize children's learning.

Self-regulation as promotive for academic achievement in young children across risk contexts.

The link between self-regulation and academic achievement in young children is well-documented. However, few studies have examined the extent to which different aspects of self-regulation are more important for early numeracy and literacy for those in contexts of high cumulative risk, such as children experiencing homelessness. In the current study, 116 children ages 4;0-7;1 years (58 residing in an emergency homeless shelter and 58 from a community participant pool) completed assessments of math and reading, as well as multiple measures of self-regulation: executive function (EF), emotion regulation (ER), and respiratory sinus arrhythmia (RSA). Parents completed a questionnaire about their children's behavioral regulation. We examined whether sample (i.e., shelter or community) moderated the association between each aspect of self-regulation and academic outcomes. Results showed a main effect of EF skills on early numeracy, and this relation did not differ across samples. Intervention efforts to promote academic competencies might specifically target EF in those who struggle with early EF skills regardless of risk context.

They can interact, but can they learn? Toddlers' transfer learning from touchscreens and television.

Despite the ubiquity of touchscreen applications and television programs for young children, developmental research suggests that learning in this context is degraded relative to face-to-face interactions. Most previous research has been limited to transfer of learning from videos, making it difficult to isolate the relative perceptual and social influences for transfer difficulty, and has not examined whether the transfer deficit persists across early childhood when task complexity increases. The current study examined whether the transfer deficit persists in older children using a complex puzzle imitation task constructed to investigate transfer from video demonstrations. The current test adapted this task to permit bidirectional transfer from touchscreens as well. To test for bidirectional transfer deficits, 2.5- and 3-year-olds were shown how to assemble a three-piece puzzle on either a three-dimensional magnetic board or a two-dimensional touchscreen (Experiment 1). Unidirectional transfer from video was also tested (Experiment 2). Results indicate that a bidirectional transfer deficit persists through 3 years, with younger children showing a greater transfer deficit; despite high perceptual similarities and social engagement, children learned less in transfer tasks, supporting the memory flexibility account of the transfer deficit. Implications of these findings for use of screen media (e.g., video, tablets) in early education are discussed.

Associations between executive function and early math and literacy skills in preschool children.

The current study directly compared the magnitude of associations between executive function (EF) and math versus literacy and investigated whether they differed by age within the preschool years. Participants were 92 typically developing, preschool children in the United States (M age=58.53 months; 47.8% Female; 58.7% White; 29.3% Non-White). Children completed a developmentally sensitive battery of direct EF assessments, math and literacy achievement tests, and IQ tests. Results showed an EF Composite was associated with math, but not literacy, after controlling for age, verbal and nonverbal IQ, and socioeconomic status. Extending prior work to a younger age, we examined whether the association between EF and academic achievement was moderated by age but found no significant interactions. These findings support the link between EF and math before kindergarten and indicate a similar magnitude of associations in younger and older preschoolers.

Experimental Paradigm for Measuring the Effects of Self-distancing in Young Children.

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.

Individual differences in the effectiveness of self-distancing for young children's emotion regulation.

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.

Do semantic contextual cues facilitate transfer learning from video in toddlers?

Young children typically demonstrate a transfer deficit, learning less from video than live presentations. Semantically meaningful context has been demonstrated to enhance learning in young children. We examined the effect of a semantically meaningful context on toddlers' imitation performance. Two- and 2.5-year-olds participated in a puzzle imitation task to examine learning from either a live or televised model. The model demonstrated how to assemble a three-piece puzzle to make a fish or a boat, with the puzzle demonstration occurring against a semantically meaningful background context (ocean) or a yellow background (no context). Participants in the video condition performed significantly worse than participants in the live condition, demonstrating the typical transfer deficit effect. While the context helped improve overall levels of imitation, especially for the boat puzzle, only individual differences in the ability to self-generate a stimulus label were associated with a reduction in the transfer deficit.

Specificity of the bilingual advantage for memory: examining cued recall, generalization, and working memory in monolingual, bilingual, and trilingual toddlers.

The specificity of the bilingual advantage in memory was examined by testing groups of monolingual, bilingual, and trilingual 24-month-olds on tasks tapping cued recall, memory generalization and working memory. For the cued recall and memory generalization conditions, there was a 24-h delay between time of encoding and time of retrieval. In addition to the memory tasks, parent-toddler dyads completed a picture-book reading task, in order to observe emotional responsiveness, and a parental report of productive vocabulary. Results indicated no difference between language groups on cued recall, working memory, emotional responsiveness, or productive vocabulary, but a significant difference was found in the memory generalization condition with only the bilingual group outperforming the baseline control group. These results replicate and extend results from past studies (Brito and Barr, 2012, 2014; Brito et al., 2014) and suggest a bilingual advantage specific to memory generalization.
