Lahat, Ayelet; Helwig, Charles C.; Zelazo, Philip David – Cognitive Development, 2012
Moral and conventional violations are usually judged differently: Only moral violations are treated as independent of social rules. To investigate the cognitive processing involved in the development of this distinction, undergraduates (N = 34), adolescents (N = 34), and children (N = 14) read scenarios presented on a computer that had 1 of 3…

Defeyter, Margaret Anne; Russo, Riccardo; McPartlin, Pamela Louise – Cognitive Development, 2009
Items studied as pictures are better remembered than items studied as words even when test items are presented as words. The present study examined the development of this picture superiority effect in recognition memory. Four groups ranging in age from 7 to 20 years participated. They studied words and pictures, with test stimuli always presented…

Lehrer, Richard; Schauble, Leona; Lucas, Deborah – Cognitive Development, 2008
A sixth-grade class investigated the ecologies of two local retention ponds over the course of one school year. In this context, instruction assisted development as students designed models of the pond in one-gallon jars and attempted to stabilize these jars in sustainable ecosystems that could be used to study questions about the ponds.…

Strand-Cary, Mari; Klahr, David – Cognitive Development, 2008
We explore the immediate and longer term consequences of different types of instruction about a central topic in middle school science: the "Control of Variables Strategy" (CVS). CVS represents the procedural and conceptual basis for designing simple, unconfounded experiments, such that unambiguous causal inferences can be made. CVS…

Cinan, Sevtap – Cognitive Development, 2006
This study examined developmental changes in concept formation, rule switching, and perseverative behaviors of children in the WCST by altering visual features of the test and using a new test score--the "zigzag" error score--which shows the number of shifts made between two incorrect concepts or rules. Instead of the original four 3-dimensional…
