The effects of embedding standard Deese/Roediger-McDermott (DRM) lists into stories whose context biased interpretation either toward or away from the overall themes of the DRM lists on both true and false recognition were investigated with 7- and 11-year-olds. These biased story contexts were compared with the same children's susceptibility to…

Two experiments examined biases in children's (5/6- and 7/8-year-olds) and adults' moral judgments. Participants at all ages judged that it was worse to produce harm when harm occurred (a) through action rather than inaction (omission bias), (b) when physical contact with the victim was involved (physical contact principle), and (c) when the harm…

Decisions can be made by applying a variety of decision-making rules--sequential rules in which decisions are based on a sequential evaluation of choice dimensions and the integrative normative rule in which decisions are based on an integration of choice dimensions. In this study, we investigated the developmental trajectory of such…

To investigate children's theories of motivation, we asked 166 children (8-12 years of age) to rate the effect of various motivational strategies on task interest, over the short and long terms, in activities described as appealing or unappealing. Children viewed the rewards strategy as resulting in greatest interest except when implemented over…

According to construal level theory, psychological distance promotes more abstract thought. Theories of creativity, in turn, suggest that abstract thought promotes creativity. Based on these lines of theorizing, we predicted that spatial distancing would enhance creative performance in elementary school children. To test this prediction, we primed…

This study examined adults' evaluations of likeability and attractiveness of children's faces from infancy to early childhood. We tested whether Lorenz's baby schema hypothesis ("Zeitschrift fur Tierpsychologie" (1943), Vol. 5, pp. 235-409) is applicable not only to infant faces but also to faces of children at older ages. Adult participants were…

In the Dimension Change Card Sort (DCCS) task, 3-year-olds can sort cards well by one dimension but have difficulty in switching to sort the same cards by another dimension when asked; that is, they perseverate on the first relevant information. What is the information that children perseverate on? Using a new version of the DCCS, the experiments…

Focuses on individual strengths of articles by Jensen and van der Maas, and Halford et al., and the power of their combined perspectives. Suggests a performance model that can both evaluate specific theoretical claims and reveal important data features that had been previously obscured using conventional statistical analyses. Maintains that the…

This response to Brainerd and Reyna's paper (in this issue), questions whether output-interference and resource theories can readily be differentiated empirically. Argues that dual-task studies, while important, do not serve as the critical tests of the resources hypothesis. (RH)

Trained preschoolers and adults on three sets of successive discriminations with stimuli labeled A, B, and R. Tested for derived stimulus-response relations and stimulus-stimulus relations. Adults displayed class-consistent B-R and A-B performances over all conditions. Children's display of class-consistent B-R performance varied by training…

Epistemological and methodological differences which underlie empiricist v rationalist science are described. (Author/MP)

Although it is now well established that object concepts are situated within broader systems of theoretical knowledge, it is less clear how theories influence the use of object concepts at various points throughout the continuum of expertise. Two studies were conducted to investigate the impact of specific theories (concerning dinosaurs) and…

Discusses when one can infer children's use of a rule, the mechanisms underlying the development of rule use, and the relation between understanding and execution. Contrasts relational complexity theory with cognitive complexity and control theory. (Author/KB)

Four experiments examined exogenous orienting in 3.5-month-olds. Found that sensitivity to a small moving bar was lower when most of the red bars were in the visual field contra-lateral to this probe. The distribution of color within the visual field biased attention, making it either more or less likely that the infant detected a moving stimulus.…

Maintains that recent elaborations of the Baddeley and Hitch working memory model offer a better account of processes underlying cognitive development than that by existing neo-Piagetian interpretations. Argues that the episodic buffer, newly added to the model, offers a way of dealing with more complex cognitive activities. Suggests that attempts…
