Adolescence is a crucial time of identity formation, scholastic and social demands, future concerns, and relationship changes. Adolescents are especially susceptible to psychological issues like pessimism, which can hinder their progress and well-being. Cognitive flexibility may help adolescents adjust to these challenges and improve subjective…

The late positive potential (LPP), an event-related potential reflecting affective processing, may exhibit developmental shifts in magnitude and scalp location. In the present longitudinal study, 501 youth (47.3% female; 89.4% White; 12.0% Hispanic) completed the emotion interrupt task to elicit the LPP to neutral, positive, and negative images at…

This longitudinal study investigates metacognitive development in children aged four to six (N = 148; 74 girls; 106 White, 21 multiracial, 17 Black, 3 Asian, 1 Latino; collected in 2017-2019) compared to adults (N = 26, 13 women; collected in 2022). We assessed metacognitive monitoring and control using experimenter-elicited and self-generated…

Hand raising is a key student behavior in everyday teacher--student interactions. Using a longitudinal research design, we explored the stability of hand raising and its directional relations with student learner characteristics over time. We observed students' hand-raising behavior using video-recordings of 376 German high school students taken…

There is a wide debate on the convenience of grade retention for students' future cognitive development. Nevertheless, due to the endogenous characteristics of grade retention to explain students' academic performance, most of the literature fails in capturing its actual influence. In the present research, we intend to get as close as possible to…

Increased focus on resting-state functional connectivity (rsFC) and the use and accessibility of functional near-infrared spectroscopy (fNIRS) have advanced knowledge on the interconnected nature of neural substrates underlying executive function (EF) development in adults and clinical populations. Less is known about the relationship between rsFC…

Children are unique humans and experience varied development even though they are of the same gene or the same sex but grow and develop according to their respective characteristics. Of course, this condition also demands adjustments in providing appropriate and varied stimuli and responses. This study aims to observe the growth and development of…

Accelerated longitudinal designs (ALDs) provide an opportunity to capture long developmental periods in a shorter time framework using a relatively small number of assessments. Prior literature has investigated whether univariate developmental processes can be characterized with data obtained from ALDs. However, many important questions in…

This paper follows an earlier report of young children's object play activities investigated in a cross-sectional sample of 289 typically developing children. Thirty-minute videotaped observations were taken of children at 8, 12, 18, 24, 30, 36, 42, 48, 54, and 60 months of age in their homes. Forty-nine percent were boys. Children were identified…

In a yearlong ethnographic study, we actively participated as members of the national planning committee for fourteen local climate conferences, we examined how citizen participation was imagined and enacted. We introduce a framework for studying the relationship between cognitive engagement, learning, and civic engagement in the public sphere. We…

Dietary intake can affect the physical, cognitive, and socioemotional development of young children. Few studies have explored the relationships between dietary intake and the cognitive and socioemotional dimensions of school readiness. This study aimed to investigate the longitudinal associations between children's dietary intake in early…

Previous research on Montessori preschool education is inconsistent and prone to analytic flexibility. In this preregistered study, disadvantaged preschoolers in a French public school were randomly assigned to either conventional or Montessori classrooms, with the latter being adapted to French public education. Adaptations included fewer…

It is well established that parent-child dyadic synchrony (e.g., mutual emotions, behaviors) can support development across cognitive and socioemotional domains. The advent of simultaneous two-brain "hyperscanning" (i.e., measuring the brain activity of two individuals at the same time) allows further insight into dyadic "neural…

Previous research on children's knowledge about the mind has primarily focused on their comprehension of false beliefs, leaving the conceptualization of thoughts and thinking less explored. To address this gap, we developed a new assessment tool, the interview about the mind (IaM), to assess children's understanding of the mind. Two studies…

Intelligence (IQ) scores are used in educational and vocational planning for individuals with autism spectrum disorder (ASD) yet little is known about the stability of IQ throughout development. We examined longitudinal age-related IQ stability in 119 individuals with ASD (3-36 years of age at first visit) and 128 typically developing controls.…
