In some contexts (e.g., legal and medical), it is imperative that children indicate when they do not understand an adult's question. Yet, little research has examined children's clarification requests. We asked 122 4- to 9-year-olds tricky and simple interview questions to assess how often and how children request clarification in interviews, the…

In four experiments, we investigate how the ability to detect irrelevant explanations develops. In Experiments 1 and 2, 4- to 8-year-olds and adults rated different types of explanations about "what makes cars go" individually, in the absence of a direct contrast. Each explanation was true and relevant (e.g., "Cars have engines that…

The study aimed to investigate the effect of an interdisciplinary STEM course on children's attitudes of learning and engineering design skills. A total of 449 elementary school children in China were recruited from three different grade levels (i.e., second, fourth and sixth grade) to participate in this study. All participants attended a weekly…

This study examined how 5- and 9-year-old children (N = 40) produce pantomimes of object use on verbal request. The task required participants to enact an action with an imagined object. Results showed that with age, children (a) proceeded from body part as object to imaginary object and (b) incorporated into their pantomimes more distinctive…

Formal climate education without consideration of the ocean is incomplete. The effectiveness of a new climate lesson for youth that includes the ocean-climate nexus was examined by delivering the lesson to nine classes situated in separate British Columbia, Canada public schools and assessing the students' understanding of basic climate concepts…

Remembering to carry out intended actions in the future, known as prospective memory (PM), is an important cognitive ability. In daily life, individuals remember to perform future tasks that might rely on effortful processes (monitoring) but also habitual tasks that might rely on more automatic processes. The development of PM across childhood in…

Suppose you are presented with 2 informants who have provided answers to the same question. One provides a precise and confident answer, and the other says that they do not know. If you were asked which of these 2 informants was more of an expert, intuitively you would select the informant who provided the certain answer over the ignorant…

The aim of the present study was to gain an insight into French young people's conceptual development regarding the greenhouse effect. Because this effect cannot be directly manipulated, we can assume that its conceptualization is mainly shaped through the sharing of information. Eighty French students from Grade Seven through to adulthood…

Across 3 experiments, we found evidence that information about who owns an artifact influenced 5- to 10-year-old children's and adults' judgments about that artifact's primary function. Children's and adults' use of ownership information was underpinned by their inference that owners are typically familiar with owned artifacts and are therefore…

Rigorous evaluation of social and emotional learning programs requires the use of measures that provide reliable and valid information on the meaningful differences in children's social emotional skills across treatment and control groups, as well as changes over time. In contexts affected by conflict and crisis, few measures can provide the…

Recent research questions whether children conceptualize race as stable. We examined participants' beliefs about the relative stability of race and emotion, a temporary feature. Participants were White adults and children ages 5-6 and 9-10 (Study 1) and racial minority children ages 5-6 (Study 2). Participants were presented with target children…

According to Klahr's (2000, 2005; Klahr & Dunbar, 1988) Scientific Discovery as Dual Search model, inquiry processes require three cognitive components: hypothesis generation, experimentation, and evidence evaluation. The aim of the present study was to investigate (a) when the ability to evaluate perfect covariation, imperfect covariation,…

Students' abstract reasoning abilities can differ from one society to another. Students' profiles play significant roles in these differences. The aim of the study is to determine the relationship between middle school students' cognitive development levels and their profiles (age, gender, and science achievement) using the Science Cognitive…

Adolescents, ages 11-12 and 13-14, were tested for maturity of judgment about stability-change situations and about time perspective. (CP)

Overall correlations between personality/motivation and verbal reasoning, divergent thinking, and creative writing in 1,416 children, aged 10-13 were low, suggesting that classroom climate and teaching methods may affect this relationship. (Tests are appended.) (Available in microfiche from: Carfax Publishing Company, Haddon House,…
