BACKGROUND Intervention strategies and developmental models of stress have been criticized for failing to integrate social psychological variables. This study investigates both self-referential cognitive mediators (perceived threat and control) and a social psychological moderator (ethnic/religious identity) of the effect of peer-victimization upon… (More)

Research has shown that the beneficial effects of peer collaboration are not always apparent until some time has elapsed. Such delayed effects are not readily incorporated in current models of collaborative learning, but because they constitute incubation effects in the psychological sense of the term, they should in principle be consistent with cognitive… (More)
The conceptual understanding that children display when predicting physical events has been shown to be inferior to the understanding they display when recognizing whether events proceed naturally. This has often been attributed to differences between the explicit engagement with conceptual knowledge required for prediction and the tacit engagement that… (More)
Adults make erroneous predictions about object fall despite recognizing when observed displays are correct or incorrect. Prediction requires explicit engagement with conceptual knowledge, whereas recognition can be achieved through tacit processing. Therefore, it has been suggested that the greater challenge imposed by explicit engagement leads to elements… (More)
A distinction can be drawn between extensive and intensive quantities. Extensive quantities (e.g., volume, distance), which have been the focus of developmental research, depend upon additive combination. Intensive quantities (e.g., density, speed), which have been relatively neglected, derive from proportional relations between variables. Thus, while… (More)
