Problem solving is an important cognitive skill that children use to plan and navigate various developmental and social tasks. Although previous research was theory-grounded and systematic, to our knowledge, no research has observed and documented children's problem solving as a primary objective in naturalistic developmental contexts, such as…

This study used a person-centered approach to examine mother-daughter dyad behaviors when jointly solving addition problems during a card game. The goal was to identify maternal and child profile behaviors during the interaction as predictors of children's autonomous addition accuracy and strategy use at the end of first grade. Videotaped…

This study examined if solving arithmetic problems hinders undergraduates' accuracy on algebra problems. The hypothesis was that solving arithmetic problems would hinder accuracy because it activates an operational view of equations, even in educated adults who have years of experience with algebra. In three experiments, undergraduates (N = 184)…

We investigated the effects of different amounts of distraction on preschoolers' task performance and attention. Children 3.5 and 4 years of age completed problem-solving tasks in one of three conditions: no distraction, intermittent (periodic) distraction, or continuous distraction. The results revealed differential effects of the distractors at…

A modified elicited imitation task was used to examine the development of the ability to resist and overcome interference in the 2nd and 3rd years of life. In the modified task, distractor props were included in the test array, so that children could imitate the modeled sequence but could also produce actions with the additional props provided,…

Three studies examined whether mathematics can propel the development of physical understanding. In Experiment 1, 10-year-olds solved balance scale problems that used easy-to-count discrete quantities or hard-to-count continuous quantities. Discrete quantities led to age typical performances. Continuous quantities caused performances like those of…

Research using the Dimensional Change Card Sort (DCCS) showed that young children are usually able to sort accurately by an initial rule but are unable to switch to a new rule when the two rules conflict. In 2 experiments, the DCCS was modified to study the effects of feedback on 3- to 5-year-old children in a problem-solving task. In Experiment…
