A great part of the research in adolescent popularity is based on sociometric methods, not always distinguishing between social preference (acceptance or likeability) and perceived popularity (visibility or salience), which has practical and theoretical implications. The aim of this work was to analyze the features that a sample of 406 Spanish…

In language conferences, student papers, some linguistics textbooks, and wider culture, the critical period hypothesis is presented as factual despite still being fiercely debated in academic literature. The widespread popular acceptance of the hypothesis contrasts with a sharp debate and criticism of it in academic literature (Muñoz &…

This article introduces the revised and updated "DC:0-5™: Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood." The authors describe the past and current efforts to create a developmentally based classification system for very young children. DC:0-3, published in 1994 by ZERO TO THREE,…

For decades, scholars have examined how children first recognize emotional facial expressions. This research has found that infants younger than 10 months can discriminate negative, within-valence facial expressions in looking time tasks, and children older than 24 months struggle to categorize these expressions in labeling and free-sort tasks.…

The potential of physical activity and sport programs to promote positive youth development (PYD) is well-recognized among youth sport researchers and practitioners. More recently, physical literacy has gained traction among sport organizations as an important component of long-term athlete development. With conceptual roots in academic writing,…

Most theories of learning would predict a gradual acquisition and refinement of skills as learning progresses, and while some highlight exponential growth, this fails to explain why natural cognitive development typically progresses in stages. Models that do span multiple developmental stages typically have parameters to "switch" between…

The purpose of this study is investigating the convenience of cartoon films with respect to the developmental levels of pre-school children. Content analysis, one of the techniques of qualitative research, was used in the study. 10 cartoon films, five local and five foreign, showed in Turkish television channels from the year of 2014 to 2015 were…

Sometimes parents just do not know where to begin once their child has been diagnosed as deaf or hearing impaired. This booklet helps answer some of the questions these parents might have. A resource section has been included for parents and professionals for future reference. One of the most important things to remember is that, once a child has…

Purpose: The aim of this study was to collect auditory-perceptual data on established symptom categories of dysarthria from typically developing children between 3 and 9 years of age, for the purpose of creating age norms for dysarthria assessment. Method: One hundred forty-four typically developing children (3;0-9;11 [years;months], 72 girls and…

In a previous study, we reported the first measurements of pre-movement and sensorimotor cortex activity in preschool age children (ages 3-5 years) using a customized pediatric magnetoencephalographic system. Movement-related activity in the sensorimotor cortex differed from that typically observed in adults, suggesting that maturation of cortical…

This prospective study examined the developmental changes over time of adolescents diagnosed in toddlerhood with autism spectrum disorder and searched for child characteristics at toddlerhood that predict outcome at adolescence. The study included 65 participants who were divided into low cognitive (developmental quotient [less than] 85; N = 41)…

One of the factors that determine the success of mathematics learning is the learning media used. Learning media can help students to create mathematical abstract mathematics that is abstract. In addition to media, meaningful learning is a learning that is adapted to the students' cognitive development. According to Piaget, junior high school…

Using landmarks and other scene features to recall locations from new viewpoints is a critical skill in spatial cognition. In an immersive virtual reality task, we asked children 3.5-4.5 years old to remember the location of a target using various cues. On some trials they could use information from their own self-motion. On some trials they could…

Western development organizations frequently target youth in conflict settings to participate in peaceful, cooperative activities to promote nation-building and deter violence. In this article, Heddy Lahmann examines the narratives of fifteen youth who participated in a US-funded nonformal arts education program in Afghanistan, which operated with…

Although the human proclivity to engage in impression management and care for reputation is ubiquitous, the question of its developmental outset remains open. In 4 studies, we demonstrate that the sensitivity to the evaluation of others (i.e., evaluative audience perception) is manifest by 24 months. In a first study, 14- to 24-month-old children…
