Two studies investigated young 2- and 3-year-old Turkish children's developing understanding of normativity and freedom to act in games. As expected, children, especially 3-year-olds, protested more when there was a norm violation than when there was none. Surprisingly, however, no decrease in normative protest was observed even when the actor…

Two experiments (N=136) studied how 4- to 6-month-olds perceive a simple schematic event, seen as goal-directed action and reaction from 3 years of age. In our causal reaction event, a red square moved toward a blue square, stopping prior to contact. Blue began to move away before red stopped, so that both briefly moved simultaneously at a…

The change detection task has been used in dozens of studies with adults to measure visual working memory capacity. Two studies have recently tested children in this task, suggesting a gradual increase in capacity from 5 years to adulthood. These results contrast with findings from an infant looking paradigm suggesting that capacity reaches…

Attributional style models of depression in adults (Abramson et al. 1989, 1978) have been adapted for use with children; however, most applications do not consider that children's understanding of causal relations may be qualitatively different from that of adults. If children's causal attributions depend on children's level of cognitive…

Using a new paradigm for measuring children's saving behaviors involving two marble games differing in desirability, we assessed whether 3-, 4-, and 5-year-olds saved marbles for future use, saved increasingly on a second trial, saved increasingly with age, and were sensitive to the relative value of future rewards. We also assessed whether…

This study investigated how young children's increasingly flexible use of spatial reference frames enables accurate search for hidden objects by using a task that 3-year-olds have been shown to perform with great accuracy and 2-year-olds have been shown to perform inaccurately. Children watched as an object was rolled down a ramp, behind a panel…

As effortful control (EC), the self-regulation aspect of temperament, has been argued to play a key role in the normal and psychopathological course of development, research adding to the construct validity of EC is needed. In the current study, interrelations between the temperament construct of EC and the efficiency of the executive attention…
