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.…

Early learning programs impact students, especially those with developmental delays. These formative years play a vital role in the overall development of the students' skills. School districts want to reach these special education students during these crucial years to help close the developmental delay gap. This quantitative study examines the…

This study considers the specificity of 3,136 Korean students' occupational preferences during secondary school and examines whether the types of high school are related to the crystallization in occupational preferences by applying binary growth models. Based on Super's developmental stage, this study shows that students largely formulate solid…

The present study investigates developmental patterns of fear in adolescence. It is based on longitudinal data collected as a part of the European Longitudinal Study of Pregnancy and Childhood (ELSPAC) project. A total of 186 Czech adolescents (43% girls) were assessed repeatedly at the age of 11, 13, and 15 years. The free-response method was…

Determining which dimensions of social classification are culturally significant is a developmental challenge. Some suggest this is accomplished by differentially privileging intrinsic visual cues over nonintrinsic cues (Atran, 1990; Gil-White, 2001), whereas others point to the role of noun labels as more general promoters of kind-based reasoning…

Describing how much and what type(s) of change are evident in civic engagement across adolescence is a fundamental starting point for advancing developmental theory in the civic domain. Using five annual waves of data from a large national U.S. sample spanning 8th-12th grades, our study describes civic engagement typologies and transitions in and…

The purposes of this study were to compare the age of onset of the voice change in African American, White, and Hispanic male students, as well as to describe characteristics of the changing male voice in fourth-, fifth-, and sixth-grade students, using Cooksey's maturation stages. Participants included volunteers from two urban elementary…

Stage theory represents a concise explanation for change in teacher professional development with gained experience in the classroom. This study examines the "self-task-impact" stage chronology proposed by concerns-based theory within the framework of longitudinal research on beginning teaching. The study investigated developmental change in a…

The longitudinal interrelations among age, visual and auditory short-term memory, and the concrete operational tasks of class inclusion and combinatorial reasoning were investigated over four testing occasions in a sample of 134 students, initially ranging from 5 to 12 years in age. The Piagetian task battery involved placement of colored…
