Werker, Janet F.; Hall, D. Geoffrey; Fais, Laurel – Journal of Cognition and Development, 2004
U-shaped developmental functions, and their N-shaped cousins, have intrigued developmental psychologists for decades because they provide a compelling demonstration that development does not always entail a monotonic increase across age in a single underlying ability. Instead, the causes of development are much more complex. Indeed,…

Namy, Laura L.; Campbell, Aimee L.; Tomasello, Michael – Journal of Cognition and Development, 2004
This article reports 2 experiments examining the changing role of iconicity in symbol learning and its implications regarding the mechanisms supporting symbol-to-referent mapping. Experiment 1 compared 18- and 26-month-olds' mapping of iconic gestures (e.g., hopping gesture for a rabbit) vs. arbitrary gestures (e.g., dropping motion for a rabbit).…

Cashon, Cara H.; Cohen, Leslie B. – Journal of Cognition and Development, 2004
The development of the "inversion" effect in face processing was examined in infants 3 to 6 months of age by testing their integration of the internal and external features of upright and inverted faces using a variation of the "switch" visual habituation paradigm. When combined with previous findings showing that 7-month-olds use integrative…

Brainerd, C. J. – Journal of Cognition and Development, 2004
The aim of this article is to introduce readers to an alternative way of applying U-shaped functions to understand development, especially cognitive development. In classical developmental applications, age is the abscissa; that is, in the fundamental equation B = f(A), some behavioral variable (B) plots as a U-shaped or inverted U-shaped function…

Feldman, David Henry; Benjamin, Ann C. – Journal of Cognition and Development, 2004
There is by this point no doubt that backward, regressive, negative or degenerative movements occur in cognitive development. The question is "why?" The challenges of the phenomenon have been and continue to be mainly two: identify the range and variety of systematic backward movements that appear in development; and, provide better and better…

Marcovitch, Stuart; Lewkowicz, David J. – Journal of Cognition and Development, 2004
The articles in this collection consider one very interesting puzzle of development: U-shaped developmental functions. At some point during development, an organism might exhibit what seems like a regression from its expected developmental trajectory and, according to continuity models of development, this is aberrant. In this special issue,…

Principe, Gabrielle F. – Journal of Cognition and Development, 2004
To examine the extent to which differences in the initial encoding of information affect preschoolers' vulnerability to suggestion, 4 groups of 4-year-olds (N = 54) individually participated in a simulated shopping event in which they were asked to purchase 6 items from a specially constructed grocery store. Half the children had only 1…

Demetriou, Andreas; Raftopoulos, Athanasios – Journal of Cognition and Development, 2004
Developmental psychologists have been preoccupied with the shape or form of development since the early days of developmental psychology. One of their main concerns has been to specify the developmental function of the characteristics (i.e., behaviors, traits, abilities, processes, etc.) that are of interest to them. This is equivalent to saying…

Vosmik, Jordan R.; Presson, Clark C. – Journal of Cognition and Development, 2004
Map-guided wayfinding requires updating the map-space relation whenever we turn. In 3 studies, children used a map to follow a path with two 90 degree turns. Although carrying the map, children rarely physically adjusted the map after turns. They performed well when the map was aligned with the space (on the 1st and 3rd legs), and they performed…

Smith, Lesley A.; Williams, Joanne M. – Journal of Cognition and Development, 2004
This study explores children's understanding of the causal origins of disabilities. Using a forced-choice explanation task, children's understanding of social-psychological, physical, and biological causal explanations of disabilities was considered. We presented 79 children (26 4- to 5-year-olds, 26 6- to 7-year-olds, and 27 10- to 11-year-olds)…

DeMarie, Darlene; Miller, Patricia H.; Ferron, John; Cunningham, Walter R. – Journal of Cognition and Development, 2004
Path analysis was used to test theoretical models of relations among variables known to predict differences in children's memory--strategies, capacity, and metamemory. Children in kindergarten to fourth grade (chronological ages 5 to 11) performed different memory tasks. Several strategies (i.e., sorting, clustering, rehearsal, and self-testing)…

Kavsek, Michael – Journal of Cognition and Development, 2004
Several investigations have shown that young infants perceive the unity of a center-occluded object when the visible ends of the object undergo common motion but not when the object remains stationary. This study is an extension of earlier investigations on object unity in that it assesses amodal completion of stationary circles in which one half…

Siegler, Robert S. – Journal of Cognition and Development, 2004
Interest in U-shaped development has itself undergone a U-shaped progression. Twenty-five years ago, interest in U-shaped development was high. This interest was evident at a 1978 conference in Tel Aviv on "U-shaped Behavioral Growth" that resulted in the publication of a book of the same title 4 years later (Strauss, 1982). The breadth…
