Participants identified each statement as a lie or as the truth, morally judged it as good or bad, and decided whether or not to assign punishment to the speaker. All children received measures of first- and second-order false-belief understanding. Although 4-year-olds were above chance in their identification accuracy, they did not differentiate between lies and truths in their moral judgments or punishments. Five-year-olds outperformed 4-year-olds in their identification accuracy, morally judged lies more negatively than truths, and assigned speakers of lies more punishment than those who told truths. Five-year-olds also treated lies about misdeeds more negatively than politeness lies in their moral judgments and punishments. Children’s identification of both lies and truths related to their first-order false-belief understanding, while their moral judgments and punishment of lies related to their second-order false-belief understanding. These findings suggest that different considerations are made when children reason about the conceptual and moral differences between lies and truths.

Employing a marble run paradigm, 54 children participated in two trials in which they could use their marbles immediately on a less desirable run, or save for a more desirable run. Twenty-nine children received the opportunity to create a budget. On Trial 1, children in the budgeting condition saved significantly more than did children in the control condition, and their planning ability related to saving (after controlling for age and language). Those who consistently budgeted at least one marble for the more desirable run were more likely to save. Control children's performance improved across trials, with no between-condition differences on Trial 2. Self-control was not related to saving.

We know very little about preschoolers' ability to coordinate more than one dimension simultaneously (concurrent cognitive flexibility). Here we report on a new task, the Multidimensional Card Selection Task, which was designed to measure children's ability to consider two dimensions, and then three dimensions, concurrently (e.g., shape and size, and then shape, size, and color). More than half of the preschoolers in our sample of 107 (50 3-year-olds and 57 4-year-olds) could coordinate three dimensions simultaneously and consistently across three test trials. Furthermore, performance on the Multidimensional Card Selection Task was related, but not identical...

In our main task, children used representations on a perspective line drawing to find stickers hidden in a model room. To compare the contributions made by various cognitive skills with children's understanding of different types of representations, we manipulated the resemblance between the representations and their referents. Our results indicate that when representations are iconic (i.e., look like their referents), children have very little difficulty with the task. Controlling for performance on this baseline version of the task, we found that specific cognitive skills are differentially predictive of performance when using arbitrary and conflicting representations (i.e., symbols). When the representation was arbitrarily linked to the sticker, performance was related to phonological and visuospatial working memory. When the representation matched the color of an alternate sticker (thereby conflicting with the desired sticker), performance was related to phonological working memory and inhibitory control. We discuss the role that different cognitive skills play in representational understanding as a function of the nature of the representation-referent relation.
