M. Tomasello, A. Kruger, and H. Ratner (1993) proposed a theory of cultural learning comprising imitative learning, instructed learning, and collaborative learning. Empirical and theoretical advances in the past 20 years suggest modifications to the theory; for example, children do not just imitate but overimitate in order to identify and…

Children's mindsets about intelligence (as a quality they can grow vs. a trait they cannot change) robustly influence their motivation and achievement. How do adults foster "growth mindsets" in children? One might assume that adults act in ways that communicate their own mindsets to children. However, new research shows that many parents…

Cultural transmission is often viewed as a domain-general process. However, a growing literature suggests that learnability is influenced by content and context. The idea of a learnability landscape is introduced as a way of representing the effects of interacting factors on how easily information is acquired. Extending prior work (Barrett &…

Four decades of early childhood policy and program development indicate that evidence-based interventions can improve life outcomes, and dramatic advances in the biological and behavioral sciences now provide an opportunity to augment those impacts. The challenge of reducing the gap between what we know and what we do to promote the healthy…

Nativist and constructivist approaches to the study of development share a common emphasis on characterizing beginning and end states in development. This focus has highlighted the question of preservation and transformation--whether core aspects of the adult end state are present in the earliest manifestations during infancy. In contrast, a…

Explaining new ideas to oneself can promote transfer, but how and when such self-explanation is effective is unclear. This study evaluated whether self-explanation leads to lasting improvements in transfer success and whether it is more effective in combination with direct instruction or invention. Third- through fifth-grade children (ages 8-11;…

Many adult beliefs are based on the testimony provided by other people rather than on firsthand observation. Children also learn from other people's testimony. For example, they learn that mental processes depend on the brain, that the earth is spherical, and that hidden bodily organs constrain life and death. Such learning might indicate that…

Walkers fall frequently, especially during infancy. Children (15, 21, 27, 33, and 39 month-olds) and adults were tested in a novel foam pit paradigm to examine age-related changes in the relationship between falling and prospective control of locomotion. In trial 1, participants walked and fell into a deformable foam pit marked with distinct…

Children often perseverate, repeating prior behaviors when inappropriate. This work tested the roles of verbal labels and stimulus novelty in such perseveration. Three-year-old children sorted cards by one rule and were then instructed to switch to a second rule. In a basic condition, cards had familiar shapes and colors and both rules were stated…
