Based on a 2-component framework of episodic memory development across the lifespan (Shing & Lindenberger, 2011), we examined the contribution of memory-related binding and monitoring processes to false memory susceptibility in childhood and old age. We administered a repeated continuous recognition task to children (N = 20, 10-12 years),…

Developmental studies on heuristics and biases have reported controversial findings suggesting that children sometimes reason more logically than do adults. We addressed the controversy by testing the impact of children's knowledge of the heuristic stereotypes that are typically cued in these studies. Five-year-old preschoolers and 8-year-old…

In manual search tasks designed to assess infants' knowledge of the object concept, why does search for objects hidden by darkness precede search for objects hidden by visible occluders by several months? A graded representations account explains this decalage by proposing that the conflicting visual input from occluders directly competes with…

Reports on an experiment which involved 42 7 1/2-10 1/2-month-old infants playing a two-position hidden-object game. Results were interpreted to support and extend previous explanations of Stage IV of object-concept development. This report is a revised version of a paper presented at the biennial meeting of the Society for Research in Child…

Rejoinder to article PS 502 129. (MB)

Empirically describes the relative development of perceptual and conceptual understanding of left-right, back-front, up-down projective relationships between objects and provides a heuristic model of the cognitive processes involved in coordination of perspectives tasks. (Author/ED)

To evaluate prevalence of perseveration in early search, nine-month-olds were tested on both two- and three-location version of Piaget's AB task. Three principal findings emerged: (1) infants did not show systematic perservation on either location task; (2) they did demonstrate positive search skills; and (3) they searched using similiar methods…

Children who recognize a compensatory relationship between height-width dimensions are more susceptible to conservation training than children who do not recognize this relationship. (Authors)

Results confirm the hypothesis that identity and equivalence conservation require different mental processes. (Authors/MB)

Investigated the intercorrelations among tasks that appear to require Piagetian formal reasoning to determine whether formal reasoning is used selectively or all-pervasively. Subjects were 60 undergraduate females. (SDH)

In general, this cross-sectional validation study supports Inhelder and Piaget's claims about the development of concepts of volume and density more easily than younger subjects. (Author/WY)

Author challenges the findings of Helene Borke who presented evidence interpreted as demonstrating that children as young as 3 years of age were able to successfully abandon their own egocentric perspectives and adopt the points of view of others. Rejoinder by Borke is presented in PS 502 130. (MB)

Nine- to 18-month-old infants were presented with simple two-location manual search tasks involving invisible displacements of objects with sequence of displacements occurring before infants search. Results provided insights into age differences associated with development of logical search strategies, information-processing skills, and temporal…

Individual differences in children's conceptual strategies at 3 years of age were predicted by aspects of children's behavior and language at 13 and 24 months. Production of pointing gestures at 13 months and nouns and attributive adjectives at 24 months were positively associated with the use of a taxonomic matching strategy at 3 years of age.…
