Developmental trajectories of bullying perpetration were examined across 5 waves of longitudinal panel data among Midwestern middle school students. This study explained an unobserved heterogeneity of subgroups, each having the similar pattern of trajectories and investigated antecedents and consequences of class membership. Growth-mixture…

Inhibitory control has been widely studied in association with social and academic adjustment. However, prior studies have generally overlooked the potential heterotypic continuity of inhibitory control and how this could affect assessment and understanding of its development. In the present study, we systematically considered heterotypic…

Scholars have examined the effects of same-gender teachers on student achievement, but the findings are mixed. In this study, we use 7 years of administrative data from students in elementary and middle schools (i.e., Grades 3 through 8) in Indiana to test links between gender matching and student achievement. We find that female teachers are…

Numerous studies consider competition and jealousy within an evolutionary framework, yet less is known about the relation between aggression vis-à-vis hypercompetitiveness (i.e., competing to win) and jealousy. We investigated the longitudinal relations between hypercompetitiveness, jealousy, and aggression and the moderating role of gender in a…

As a spoken word unfolds over time, similar sounding words ("cap" and "cat") compete until one word "wins". Lexical competition becomes more efficient from infancy through adolescence. We examined one potential mechanism underlying this development: lexical inhibition, by which activated candidates suppress…

In this study we focus our research on the case analysis of an eleven-year-old boy and his close relationship with technology, specifically robotics. The methodology of the study is experimental in nature, with the aim of improving the subject's attention span through robotics, thereby favouring his educational process and, consequently, his…

The transition from middle school to high school can be a particularly challenging time for music program retention. However, when music teachers view this process through the lens of marketing, it may be possible to develop a more holistic and comprehensive approach toward student enrollment. Marketing strategies related to perception, targeting,…

Around their first birthdays, infants begin to point, walk, and talk. These abilities are appreciable both by researchers with strictly standardized criteria and caregivers with more relaxed notions of what each of these skills entails. Here, we compare the onsets of these skills and links among them across two data collection methods: observation…

Despite popular framings about skills for 21st-century jobs, there are few studies of how new media literacies unfold in workplaces, nor of how professional education programs can build on adult learners' previous experiences to foster effective digital communication practices. We argue that seminaries and divinity schools are a particularly rich…

The goal of this article was to examine gender-typed behavior longitudinally and to consider its relationship with sexual orientation in adulthood. Data were from 10,624 respondents who completed Wave 1 (adolescence), Wave 3 (emerging adulthood), and Wave 4 (early adulthood) of the National Longitudinal Study of Adolescent to Adult Health. First,…

There is general agreement that humans represent numerical, spatial, and temporal magnitudes from early in development. However, there is disagreement about whether different magnitudes converge within a general magnitude system and whether this system supports behavioral demonstrations of cross-magnitude interactions at different developmental…

In a general sense, psychology is a science that studies human and animal behaviours, and the reasons of these behaviours. The symbolic foundation date of psychology is 1879. In this year, Wilheml Wundt (1832-1920) established a psychology laboratory in Leipzig. Psychology is accepted to have started as a science with the establishment of this…

We investigate the development of text reconstruction abilities in Hebrew-speaking children, with a particular focus on verbal passive constructions. The acquisition of verbal passives in Hebrew is a late developmental milestone, closely tied to the expression of event semantics. The current study explores how narrative and informative text genres…

Young children from around the world are accessing the internet in ever increasing numbers. The rapid increase in internet activity by children aged 4-5 years in particular is due to the ease access enabled them by touchscreen internet-enabled tablet technologies. With young children now online, often independently of adult supervision, the need…

One of the core functions of explanation is to support prediction and generalization. However, some explanations license a broader range of predictions than others. For instance, an explanation about biology could be presented as applying to a specific case (e.g., "this bear") or more generally across "all animals." The current…
