Counterfactual emotions such as regret may aid future decision-making by encouraging people to focus on controllable features of personal past events. However, it remains unclear when children begin to preferentially focus on controllable features of such events. Across two studies, Australian 4-9-year-olds (N = 336, 168 females; data collected…

One-hundred-six 5-year-olds' (M[subscript age] = 5;6; SD = 0.40) were trained with second-order false belief tasks in one of the following conditions: (a) "feedback with explanation"; (b) "feedback without explanation"; (c) "no feedback"; (d) "active control." The results showed that there were significant…

Observational studies comparing child outcomes in early care and education classrooms of differing quality are often confounded by between-child differences. A within-child design, tracking children across contexts, can identify the effects of quality with less confounding. An analysis of Australian children (N = 1128, mean age 5 years, 48%…

The neurocognitive development of moral and conventional judgments was examined. Event-related potentials were recorded while 24 adolescents (13 years) and 30 young adults (20 years) read scenarios with 1 of 3 endings: moral violations, conventional violations, or neutral acts. Participants judged whether the act was acceptable or unacceptable…

Although some evidence indicates that even very young children engage in rudimentary forms of strategic behavior, the underlying mechanisms remain largely unknown. This study tested the hypothesis that uncertainty monitoring underlies such behaviors. Three-, four-, and five-year-old children ("N" = 88) completed a perceptual…

Dynamic relations during the preschool years across processes of control and understanding in the domains of emotion and cognition were examined. Participants were 263 children (42% non-White) and their mothers who were seen first when the children were 3 years old and again when they were 4. Results indicated dynamic dependence among the…

Neuroimaging studies with adults have identified cortical regions recruited when people think about other people's thoughts (theory of mind): temporo-parietal junction, posterior cingulate, and medial prefrontal cortex. These same regions were recruited in 13 children aged 6-11 years when they listened to sections of a story describing a…

Examined whether early differences in stress reactivity were related to self-recognition at 18 months. Found that self-recognition was related to greater cortisol response and less rapid quieting at 6 to 18 months, whereas cortisol and quieting responses of 2- to 4-month-olds did not differentiate self-recognizers and non-self-recognizers,…

Study attempted to determine the viability of optimal level theory as it pertains to infant perceptual and cognitive development. (Authors)

Although developmental psychologists are generally happy to endorse dissociations and gradualist views of development like Woolley's (2006), the design and interpretation of developmental research often suggests an implicit commitment to a cleaner, less dissociative, sudden-transition view of development. Such an implicit commitment may derive…

This study investigated vowel discrimination in 8-week-old infants. Using a nonnutritive, high-amplitude sucking measure in a habituation-dishabituation paradigm. (Author/SB)

Studies the distribution of attention to actors in a visual event and the influence of linguistic variables on attention. Naming an actor had a strong directing influence on attention in a neutral period and more limited effects on attention during and after the action. (RMH)

Three studies investigated toddlers' judgments and communications about how desires, perceptions, and emotions connect in people's lives and minds. Findings indicated that in appropriate circumstances, young children realized that a person's perception of desirable or undesirable objects leads to related emotional experiences. Children's…

In testing conservation of number in preschool children using both equality and inequality; 3- and 4-year-olds tended to use an acquiescence response set while 5- and 6-year-olds responded in terms of relative length. (ST)
