Developmental psychology focuses on how psychological constructs change with age. In cognitive development research, however, the specifics of this emergence is often underspecified. Researchers often provisionally assume linear growth by including chronological age as a predictor in regression models. In this work, we aim to evaluate this…

Australian children aged 6-9 years (N = 120, 71 females; data collected in 2021-2022) were tasked with remembering the locations of 1, 3, 5, and 7 targets hidden under 25 cups on different trials. In the critical test phase, children were provided with a limited number of tokens to allocate across trials, which they could use to mark target…

This study examined trajectories of repetitive sensorimotor (RSM), insistence on sameness (IS), and verbal RRBs from ages 2-19 in a well-characterized longitudinal cohort. We also tested the factor structure of the ADI-R restricted and repetitive behavior (RRB) domain at age 19 and the inclusion of a verbal RRBs factor, in addition to previously…

Even once children can accurately remember their experiences, they nevertheless struggle to use those memories in flexible new ways--as in when drawing inferences. However, it remains an open question as to whether the developmental differences observed during both memory formation and inference itself represent a fundamental limitation on…

The aim of this study was to analyze the development of Perceptual Inhibition (PI) and Selective Visual Attention (SVA) across lifespan, identifying key moments of change in the direction of development. A total of 810 Argentinian participants, ranging from 6-80 years, were included. The results revealed that PI and SVA followed similar patterns,…

Understanding how learning changes during human development has been one of the long-standing objectives of developmental science. Recently, advances in computational biology have demonstrated that humans display a bias when learning to navigate novel environments through rewards and punishments: they learn more from outcomes that confirm their…

Although exploratory play is considered a hallmark of cognitive development and learning, relatively few studies have been able to quantitatively characterize the shifts that may occur in children's approach to exploration. One reason for this gap is due to challenges coding and analyzing children's exploratory play behavior. In our paper, we…

Research and data on youth and delinquency is critical for identifying opportunities and developing strategies to support positive development through prevention and intervention. Responses to youth misbehavior by youth-serving systems -- including education, child welfare, behavioral health, and justice systems -- can play an important role in…

Despite numerous critiques of the pioneering works of developmental child psychology, these key ideas continue to resonate within the field of ECEC (early childhood education and care). This article seeks to re-animate the critique through a closer look at two current tendencies within the Nordic countries: a growing and increasingly strict age…

Purpose: Research of mindfulness-based programming/interventions (MBP) for youth has proliferated in recent years; however, heterogeneity of MBP for youth impede determination of optimal programmatic structure across developmental periods. Design/Approach/Methods: Expert MBP scientists and instructors were iteratively surveyed using the Delphi…

People reflect on their own aging, and this subjective awareness has an influence on developmental outcomes. Scholars have recently operationalized subjective aging in terms of awareness of age-related change (AARC), which captures awareness of both gains and losses. We examined associations of AARC-gains and AARC-losses with physical functioning,…

This retrospective study examines involvement in school bullying at all developmental stages, from elementary school to university, in relation to personality traits. Participants were 216 university students, 162 (75.0%) females and 54 (25.0%) males. The majority of the sample (88.9%) aged 18-24. Students completed the International Personality…

Purpose: This study aims at investigating the phonological development of the six guttural consonants of Jordanian Arabic, /[chi]/, /[voiced uvular fricative]/, /[voiceless pharyngeal fricative]/, /[voiced pharyngeal fricative]/, /[glottal stop]/, and /h/. Method: An articulation test is designed to involve two tasks: picture naming and…

A basic question about bilingual development is how the acquisition of one language affects the acquisition of the other. Previous findings are few and mixed. The present study addressed this question with longitudinal data on the dual-language vocabulary growth of 149 US-born children from Spanish-speaking immigrant families, who were followed…

Defining developmental progressions can be an important step in identifying developmental precursors and mechanisms of change, within and across areas of reasoning. In one exploratory study, we examine whether the development of children's thinking about ownership follows a systematic progression wherein some components emerge reliably before…
