This study measured the impact of the "Fitness Improves Thinking in Kids" ("FITKids") afterschool program on the executive control (i.e., maintaining focus, performing multiple cognitive processes) and physical fitness of preadolescent students. The "FITKids" program was held at the University of Illinois' campus and…

Previously, a total of 121 children with an autism spectrum disorder (ASD) performed an adaptive working memory (WM)-training, an adaptive flexibility-training, or a non-adaptive control (mock)-training. Despite overall improvement, there were minor differences between the adaptive and mock-training conditions. Moreover, dropout was relatively…

We propose that attraction errors in agreement production (e.g., the key to the cabinets are missing) are related to two components of executive control: working memory and inhibitory control. We tested 138 children aged 10 to 12, an age when children are expected to produce high rates of errors. To increase the potential of individual variation…

We investigated the spelling of derivational and inflectional suffixes by 10-13-year-old Greek children. Twenty children with dyslexia (DYS), 20 spelling-level-matched (SA) and 20 age-matched (CA) children spelled adjectives, nouns, and verbs in dictated word pairs and sentences. Children spelled nouns and verbs more accurately than adjectives and…

Previous research has shown that adolescents' attention for a peer is determined by the peer's status. This study examined how it is also determined by the status of the perceiving adolescent, and the gender of both parties involved (perceiver and perceived). Participants were 122 early adolescents (M age = 11.0 years) who completed…

In the current study, associations between individual and friends' direct and indirect aggression and depressive problems were examined. It was expected that social status would moderate these associations such that low-status preadolescents would be more similar to their unilateral friends with regard to indirect, but not direct, aggression.…

Humane education programs designed to increase children's empathy for animals are becoming more common. A quasi-experiment tested the effectiveness of one such program by comparing 80 children who had completed the program with a control group of 57 children who had not. The children read a story involving an injured dog and rated the degree of…

This study describes the implementation of a self-guiding mobile learning tool designed to support youths' engagement with the natural world as they explored the flora and fauna along one nature trail at an environmental center. Using qualitative video-based data collection and analysis techniques, we conducted two design-based research study…

Morality is an evolved aspect of human nature, yet is heavily influenced by cultural environment. This developmental study adopted an integrative approach by combining measures of socioeconomic status (SES), executive function, affective sharing, empathic concern, theory of mind, and moral judgment in predicting sharing behavior in children (N =…

This study was designed to uncover and evaluate unintended and indirect consequences of using the "Secondary Entrance Assessment" ("SEA") in Trinidad and Tobago for high-stakes selection and placement. A major argument is that the test-taker is central to consequences, both intended and unintended. Data were obtained from…

The processes of puberty, including reproductive fertility and social-role transitions, now begin earlier, last longer, and are experienced in very different contexts. Because of this, all children and adolescents need good-quality puberty education in school curricula, and this need is supported by positive cost-benefit analysis and international…

Romantic relationship quality in adolescence and early adulthood has often been linked to earlier parent-child relationship quality but it is possible that these links are nonlinear. Moreover, the role of social skills as mediator of associations between parent-child and romantic relations has been discussed but not rigorously tested. Using data…

Intraindividual differences in executive functions (EFs) have been rarely investigated. In this study, we addressed the question of whether the emotional fluctuations that schoolchildren experience in their classroom settings could generate substantial intraindividual differences in their EFs and, more specifically, in the fundamental unifying…

Life in Cambodia can be challenging and education is often seen as a key development intervention to address social and economic issues. However, rural Cambodian youth face a variety of barriers to education. The current case study examines these barriers using a questionnaire assessing youth's attitudes toward education (N = 50). Results indicate…

The authors, with Swedish elementary school students (N = 201), 9-12 years old, examined the potential significance to self-perceived academic competence of students' cross-ethnic friendship ties and prosocial behavior to better understand education's minority achievement gap. A crossed-lagged panel model was tested to investigate potential…
