Children tend to select a novel object rather than a familiar object when asked to identify the referent of a novel label. Current accounts of this so-called "disambiguation effect" do not address whether children have a general metacognitive representation of this way of determining the reference of novel labels. In two experiments…

It is often argued that metacognition includes 2 components: monitoring and control. However, it is unclear whether these components can operate independently, or whether they always operate as part of a hierarchy. The current study attempts to address this issue. In Experiment 1 (N = 90), age-related differences were assessed to examine the…

One of the lawlike regularities of psychological science is that of developmental progression--an increase in sensorimotor, cognitive, and social functioning from childhood to adulthood. Here, we report a rare violation of this law, a developmental reversal in attention. In Experiment 1, 4­- to 5­- year ­olds (n = 34) and adults (n = 35) performed…

Young children's estimates of numerical magnitude increase approximately logarithmically with actual magnitude. The conventional interpretation of this finding is that children's estimates reflect an innate logarithmic encoding of number. A recent set of findings, however, suggests that logarithmic number-line estimates emerge via a dynamic…

How do people learn categories and what changes with development? The current study attempts to address these questions by focusing on the role of attention in the development of categorization. In Experiment 1, participants (adults, 7-year-olds, and 4-year-olds) were trained with novel categories consisting of deterministic and probabilistic…

Students who return from an immersion experience often report that it was "life-changing," but how do we know that students' lives have changed, especially when change is best measured several months or years after the immersion? Each year, 1.6 million Americans participate in short-term immersion experiences or missions outside the…

Educators interact with more than 4 million infants and toddlers each week in the United States and can provide positive, nurturing experiences that enhance development. Tragically, the infant-toddler workforce in the United States often lacks the support and resources necessary to support their work. These urgent needs require comprehensive…

Piaget's classic work on cognitive development showed that engaging learners in critical discussions with peers about ideas that are "different" than theirs leads to deep conceptual understanding. Implementing such an approach in college-level STEM (Science, Technology, Engineering, Math) courses has some specific challenges: (a) Short…
