In two studies, children learned simple but adaptive decision strategies from decision feedback. In a probabilistic multi-cue decision task, we investigated children's decision strategies under different feedback conditions. In Study 1 (N = 313), 7- and 9-year-old German children learned the selective decision strategy Take-the-Best. Children…

The aim of this study was to summarize evidence about the relations between parent math support in children aged 3-5 years (from several countries in America, Asia, and Europe) and concurrent and longitudinal math outcomes. The (bio)ecological model of human development guided our hypotheses. The design and reporting of this meta-analysis used the…

Students' understanding of the meaning of the equal sign develops slowly over the primary grades. In addition to updating their representations of equations to recognize that the equal sign represents an equivalence relation rather than signaling an operation, students need to move beyond full computation to efficiently solve equivalence problems.…

Superstitious behaviors persist across time, culture, and age. Although often considered irrational and even potentially harmful, superstitions have recently been shown to have positive effects on stress levels, confidence, and ultimately, performance. However, it remains unclear how people conceive of superstitious behaviors, specifically,…

Striking weight biases emerge early in development, yet cognitive-developmental research has largely ignored weight as a social characteristic of interest. How do children conceive of weight? In particular, do children hold essentialist views of weight (i.e. do they view weight as natural, stable, inductively meaningful, and reflective of people's…

Early childhood educators' math anxiety and its relation to their frequency of pedagogic actions was examined through a questionnaire completed by 352 participants (aged 21-65) representative of the Swedish municipality where the study was conducted. Our sample contained 189 certified preschool teachers and 163 preschool caregivers who…

Previous research suggests that children's ability to label visual features (e.g. "red") and dimensions (e.g. "color") impacts attention to visual dimensions. The goal of this study is to investigate variations in the quality of the neural system supporting dimensional label comprehension and production in relation to…

Executive function (EF) skills are a set of attention-regulation skills involved in intentional, goal-directed behavior that include (but are not limited to) the cool EF skills of working memory, cognitive flexibility, and inhibitory control, and also the hot EF skill of intentional reevaluation. These skills are inevitably expressed in goal- and…

This developmental account of executive function (EF) argues that domain-general analogical processes build a functional hierarchy of skills, which vary on a continuum of abstraction, and become increasingly differentiated over time. The paper begins by showing how a functional hierarchy can capture important aspects of EF development, including…

Cognitive control (also referred to as executive functions) corresponds to a set of cognitive processes that support the goal-directed regulation of thoughts and actions. It plays a major role in complex activities and predicts later academic achievement. Importantly, while growing up, children are progressively transitioning from engaging…

The predictive validity of performance on cognitive-behavioral measures of executive function (EF) suggests that these measures index children's underlying capacity for self-regulation. In this paper, we apply ecological systems theory to critically evaluate this assertion. We argue that as typically administered, standard measures of EF do not…

Children's development of executive function is a good candidate for studying cultural differences because it is a necessary capacity for becoming competent participants in cultural activities, and yet it is also likely to be shaped by culturally organized everyday experiences, with potential consequences for children's development and learning.…

Performance on lab assessments of executive functions predicts academic achievement and other positive life outcomes. A primary goal of research on executive functions has been to design interventions that improve outcomes like academic achievement by improving executive functions. These interventions typically involve extensive practice on…

New perspectives on executive functions propose a greater involvement of context. These perspectives have implications for research in mathematical cognition. We tackle the problem that although individuals clearly exercise inhibitory control in mathematical contexts, researchers find that the relations between inhibitory control and mathematics…

The current study examined children's spontaneous private speech during the vertical and the horizontal Tube Task to shed light on the cognitive, motivational, and emotional processes underlying tool innovation. Tool innovation is defined as solving a novel problem by using or modifying objects in a new and useful way without prior instructions.…
