Recent studies established that making concurrent judgments of learning (JOLs) can significantly alter (typically enhance) memory itself--a "reactivity" effect. The current study recruited 190 Chinese children (M[subscript age] = 8.68 years; 101 female) in 2020 and 2021 to explore the reactivity effect on children's learning, its…

Evaluative conditioning (EC) refers to a change in liking of a conditioned stimulus (CS) consecutive to its repeated pairing with a valent unconditioned stimulus (US). We relied on a multinomial processing tree model to compare the processes underlying EC in middle-aged children (n = 57, M[subscript age] = 8.65, range = 6.94-11.03; 31 females) and…

When semantically-related photos appear with true-or-false trivia claims, people more often rate the claims as true compared to when photos are absent--"truthiness." This occurs even when the photos lack information useful for assessing veracity. We tested whether truthiness changed in magnitude as a function of participants' age in a…

"Place value," which underlies the meanings of multidigits, encompasses the principle of position and base-10 rules. To understand 65, one needs to know that the digits 6 and 5 occupy different positions and thus represent ordered values of different magnitudes (i.e., the "principle of position") and that the value of each…

Philosophy for Democracy is a research project which aims to examine whether and how Philosophy with Children contributes to the development of democratic skills and attitudes. Philosophy with Children seeks to develop children's critical thinking, their ability to judge, enhance their dialogical skills and attitudes and to contribute to their…

In a series of 3 experiments, the authors investigated the influence of symmetry of variables on children's and adults' data interpretation. They hypothesized that symmetrical (i.e., present/present) variables would support correct interpretations more than asymmetrical (i.e., present/absent) variables. Participants were asked to judge covariation…

A total of 267 five-, seven-, and ten-year-olds (M = 7.62), 147 in Hong Kong and 120 in the United States, evaluated hypothetical personal (and moral) events described as either essential or peripheral to actors' identity. Except for young Chinese in the peripheral condition, straightforward personal events were overwhelmingly evaluated as…

Research with adults has demonstrated a "black sheep effect" (BSE) whereby, relative to evaluations of normative group members, ingroup deviants are derogated more than outgroup deviants. The developmental subjective group dynamics (DSGD) model holds that the BSE should develop during middle childhood when children apply wider social…

Children's, adolescents', and adults' (N = 96 7-8, 10-11, and 13-14-year-olds and university students) epistemological development and its relation to judgments and reasoning about teaching methods was examined. The domain (scientific or moral), nature of the topic (controversial or noncontroversial), and teaching method (direct instruction by…

Functional Measurement (FM) has been applied to a variety of settings that can be considered as "extreme" settings; that is, settings involving participants with severe cognitive disabilities or involving unusual stimulus material. FM has, as instance, been successfully applied for analyzing (a) numerosity judgments among children as…

Using multilevel analyses, we examined the influence of domain (moral, conventional, and personal) and the familiarity of different authority figures (mother, teacher, person in charge, and stranger) in public, school, or home settings in 123 four to seven-year-old Chinese children (M = 5.6 years) in Hong Kong. Children affirmed authority more for…

The way in which children evaluate people's claims about their own psychological characteristics was examined. Among children ages 6-11 from the United States and China (total N = 243), there was an age-related increase in skepticism about self-report concerning the highly value-laden characteristics "honest", "smart", and…

Tests the construct of belief-discrepancy reasoning (i.e., judgments people make about others who disagree with them). First, fourth, seventh, and tenth graders were assessed and retested one year later. Longitudinal trends supported a four-stage development toward open-mindedness which was confirmed by another study of fourth and seventh graders…

Investigates the relationship between class inclusion and reasoning in 56 Dutch Children between 6 and 14 years of age. Concludes that when the children failed to respond correctly to questions about the validity of syllogisms, they did so because they lacked sufficient understanding of the premises. (HOD)

The development of understanding of Biblical parables on the part of 28 Swiss subjects of 7 to 50 years of age was studied. It was found that Biblical parables were interpreted through the lens of one's stage of religious judgment in the manner described by Oser's and Gmunder's (1988) model. (BB)
