Lyons, Ian M.; Huttenlocher, Janellen; Ratliff, Kristin R. – Journal of Cognition and Development, 2014
Previous studies of children's reorientation have focused on cue representation (e.g., whether cues are geometric) as a predictor of performance but have not addressed cue reliability (the regularity of the relation between a given cue and an outcome) as a predictor of performance. Here we address both factors within the same series of…

Jeong, Yoonkyung; Levine, Susan C.; Huttenlocher, Janellen – Journal of Cognition and Development, 2007
This study examines the development of children's ability to reason about proportions that involve either discrete entities or continuous amounts. Six-, 8- and 10-year olds were presented with a proportional reasoning task in the context of a game involving probability. Although all age groups failed when proportions involved discrete quantities,…

Vasilyeva, Marina; Duffy, Sean; Huttenlocher, Janellen – Journal of Cognition and Development, 2007
In the present paper we investigated the development of the ability to reproduce extent in elementary school students. Children were shown a target line in a frame and were asked to reconstruct the line in a frame of a different size. One experimental condition involved reproducing "absolute extent," i.e., drawing a line that would be…

Duffy, Sean; Huttenlocher, Janellen; Levine, Susan – Journal of Cognition and Development, 2005
Two experiments tested the ability of 4- and 8-year-old children to encode the extent of a target dowel and later discriminate between the target and a foil having a novel extent. By manipulating the heights of containers in which we presented the stimuli we tested whether children used the relation between the dowels and containers for encoding…
