The present study focused on children's deductive reasoning when performing the Latin Square Task, an experimental task designed to explore the influence of relational complexity. Building on Birney, Halford, and Andrew's (2006) research, we created a version of the task that minimized nonrelational factors and introduced new categories of items.…

We discuss the limitations of hypothesis testing using (quasi-) experiments in the study of cognitive development and suggest latent variable modeling as a viable alternative to experimentation. Latent variable models allow testing a theory as a whole, incorporating individual differences with respect to developmental processes or abilities in the…

Errors differ in degree of seriousness. We asked whether preschoolers would use the magnitude of an informant's errors to decide if that informant would be a good source of information later. Four- and 5-year-olds observed two informants incorrectly label familiar objects, but one informant's errors were closer to the correct answer than the…

Recent research on children's thinking about the future has taken multiple directions, many of which are illustrated in the contributions to this special issue. In this commentary the topic is discussed in the context of research on children's understanding of time, and some of the adaptive challenges of thinking about the future are considered.…

Children do not necessarily disbelieve a speaker with a history of inaccuracy; they take into account reasons for errors. Three- to five-year-olds (N = 97) aimed to identify a hidden target in collaboration with a puppet. The puppet's history of inaccuracy arose either from false beliefs or occurred despite his being fully informed. On a…

Four- and five-year-olds completed two sets of tasks that involved reasoning about the temporal order in which events had occurred in the past or were to occur in the future. Four-year-olds succeeded on the tasks that involved reasoning about the order of past events but not those that involved reasoning about the order of future events, whereas…

We analyze theoretical differences between conceptualist and minimalist approaches to episodic processing in young children. The "episodic-like" minimalism of Clayton and Dickinson (1998) is a species of the latter. We asked whether an "episodic-like" task (structurally similar to ones used by Clayton and Dickinson) in which participants had to…

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…

This study estimated the independent effects of age and schooling in grades 7-9 on scores obtained on invalid conditional and class syllogisms. The results, which point to a negative, albeit small, effect of out-of-school experience and to a sizeable positive effect of schooling, replicate previous findings in a different age range and support the…

The objective of this study was to explore factors that affect the difficulty of counterfactual reasoning in 3-5-year-old children and to shed light on the reason why counterfactual reasoning relates to understanding false belief [Cognitive Development, 13 (1998) 73-90]. Using travel scenarios, the difference between simple scenarios, in which…

Investigated strategies used by preschoolers to accomplish a repeatedly requested practical task. Participants satisfied customer requests for vegetables in a play store, with the number of moves and strategy type recorded and coded. Arithmetic pre- and posttests were also administered. Found that with repeated exposure, the children became…

Examines preschoolers' understanding of non-observable causal mechanism in causes of illness. Three studies were conducted using subjects from university child care centers. Subjects average five years of age. Results indicated that preschoolers recognize that appearances may be deceiving when it comes to judging causes of illness. Discusses…

Distinguishes the values of quantitative increments and qualitative shifts with regard to problem solving. Subjects were 136 children ranging from 6 through 8 years and were presented with the standard 3-disc problem to resolve in 3 minutes. Results indicated that qualitative shifts in children's representation of problem space are a crucial…
