The ability to differentiate possible events from impossible ones is an invaluable skill when reasoning about claims that transcend the perceptual evidence at hand, yet preschool-aged children do not readily make this differentiation when reasoning about physically extraordinary events [Shtulman, A., & Carey, S. (2007). "Improbable or impossible?…

Young children's integration of weight and distance information was examined using a new methodology that combines a single-armed apparatus with functional measurement. Weight and distance values were varied factorially across the item set. Children estimated how far the beam would tilt when different numbers of weights were placed at different…

Two experiments were conducted to determine whether very young children have difficulty with dual representations when change in perspective has been eliminated, that is, the task no longer requires transfer between a traversable and surveyable array. In a preliminary experiment children 30 and 36 months of age attempted to transfer an action…

Examined precursors of knowledge change in college students' developing understanding of gear movement. Found that only some participants changed their problem-solving approach after instruction. Results suggest that having multiple approaches available and using instructional information to build on not-well-developed conceptions may contribute…

Two studies examined associations between theory of mind performance and counterfactual thinking using both antecedent and consequent counterfactual tasks. Moreover, the studies examined children's abilities to generate different types of counterfactual statements in terms of direction and structure. Participants were 3-, 4-, and 5-year-old…

An experiment investigated how methods of questioning affect children's responses regarding the shape of the earth and the day/night cycle. Seventy-two children from Grade 1 and Grade 3 in a middle-class elementary school in Athens, Greece, were tested either by an open method of questioning or by a forced-choice method of questioning. The two…

The present study explores how suppositions which conflict with accepted beliefs are represented and reasoned about. Two studies test the predictions regarding the nature and developmental changes in children's ability to represent and reason about hypothetical or make-believe suppositions which violate their everyday knowledge and beliefs. In…

Compared the use of conditional logic in adult-adult and adult-child conversation. Results indicated that conversation patterns and inferences were similar except that children made fewer independent inferences and shifts in taxonomic level and responded more frequently to socially controlling statements than did adults.

Examined developmental differences in evidence evaluation skills among school children, non-college educated adults, and college students, utilizing plant growth variables. Found that children were more strongly influenced by prior beliefs and missing data than were the two adult groups. Age and educational differences were found in the…
