Are young children just random explorers who learn serendipitously? Or are even young children guided by uncertainty-directed sampling, seeking to explore in a systematic fashion? We study how children between the ages of 4 and 9 search in an explore-exploit task with spatially correlated rewards, where exhaustive exploration is infeasible and not…

Given the value placed on honesty and the negative consequences of lying, encouraging children's truth-telling is important. The present investigation assessed honesty promotion techniques for encouraging 3-8-year-old Canadian children's (Study 1: n = 301, 54% female; Study 2: n = 229, 50% female from predominantly White middle-class samples)…

To successfully navigate an uncertain world, one has to learn the relationship between cues (e.g., wind speed, atmospheric pressure) and outcomes (e.g., rain). When learning, it is possible to actively manipulate the cue values to test hypotheses about this relationship directly. Across two studies, we investigated how 5- to 7-year-olds actively…

Upper elementary students in a Title I rural school participated in an expressive arts-based resiliency small-group intervention entitled Resilient Warriors (RWs). This mixed-methods study revealed positive changes in participating students based on teacher ratings on the Strengths and Difficulties Questionnaire. We also found four qualitative…

Interventions for attention-deficit/hyperactivity disorder (ADHD) include positive behavior supports (e.g., parent training, school-based contingency management, behavioral peer interventions), training interventions (e.g., organizational skills training, social skills training, etc.), and other interventions (e.g., academic…

Anger is a central characteristic of negative affect and is relatively stable from infancy onward. Absolute levels of anger typically peak in early childhood and diminish as children become socialized and better able to regulate emotions. From infancy to school age, however, there are also individual differences in rank-order levels of anger. For…

Despite the well-established protective functions of guilt across childhood, its underlying physiological mechanisms have received little attention. We used latent difference scores (LDS) to model changes in children's (N = 267; 4- and 8-year-olds, 51% girls) skin conductance (SC) and respiratory sinus arrhythmia (RSA) while they imagined…

Posttraumatic growth theory posits that when life circumstances are perceived as stressful, secondary appraisal processes can be recruited in ways to facilitate both coping efforts and personal growth. Using a mixed-methods approach, we found mothers' most challenging experiences involved child behavior (e.g. aggression, communication, and social…

Although abundant research has demonstrated associations between psychologically controlling parenting and adolescent problem behavior, little is known about the moderating role of adolescent personality herein. This study examined whether adolescent personality moderates the associations between parental psychological control and internalizing…

Malnutrition and a lack of sufficient psychosocial support from caregivers both have a tremendous effect on children's development. Initiatives to support healthy child development in a context of poverty include caregiver interventions. There is growing evidence to support interventions that integrate psychosocial and nutritional support. The…

The present study examined the relationship between parenting styles and the psychosocial adjustment of 48 children aged 7 to 11 years, each of whom had been identified as gifted on the basis of a score of 130 or above on the Wechsler Intelligence Scale for Children--Fourth Edition. Parenting styles and child psychosocial adjustment were measured…

The author--artist, scientist, educator, and visual-spatial thinker--describes the genesis of, and provides insight into, an innovative, strength-based, visually dynamic computer-aided communication system called Chandelier©. This system is the powerful combination of a sophisticated, user-friendly software program and an organizational…

In this paper, (1) the psychosocial health in relation to (2) life-events was assessed among 156 children attending 20 schools by parents and teachers with the Child Behavior Checklist and the Caregiver-Teacher Report Form at the ages of four and six. Life-events were reported by parents. (1) According to the report, 93-96% children had no…

Identification of gene x environment interactions (GxE) for attention-deficit hyperactivity disorder (ADHD) is a crucial component to understanding the mechanisms underpinning the disorder, as prior work indicates large genetic influences and numerous environmental risk factors. Building on prior research, children's appraisals of self-blame were…

The marriage of evolution and development to produce the new discipline "evo-devo" in biology is situated in the general history of evolutionary biology, and its significance for developmental cognitive science is discussed. The discovery and description of the highly conserved, robust and "evolvable" mechanisms that organize the vertebrate body…
