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…

Children learn language by listening to speech from caregivers around them. However, the type and quantity of speech input that children are exposed to change throughout early childhood in ways that are poorly understood due to the small samples (few participants, limited hours of observation) typically available in developmental psychology. Here…

This study explored the salient characteristics of transactions within parent-child engagement and investigated relationships between transactional characteristics and future identification of autism. The main aims of the study were to (1) examine if parents/children and their initial behaviors impact the length of transaction; (2) determine…

There is growing traction regarding the valuable effects of kindness on well-being and positive interpersonal functioning. However, existing literature has paid little attention to the association of kindness with discriminatory attitudes toward people with special educational needs (SEN). This research examined the link of kindness to stigma…

A growing literature suggests that there is cross-cultural variation in levels of autism-related stigma, which may partially be explained by differences in cultural orientation or autism-related knowledge between countries. This literature has relied heavily on self-report measures of explicit attitudes towards autism; little research has examined…

This study investigated the development of educational aspirations (EAs) among Chinese youth (n = 2228, 48.61% female, 87.66% Han, M[subscript age_2010] = 11.48 years) for 6 years. Five latent classes of EA trajectories were identified. They varied greatly during early adolescence but converged around an associate degree in middle adolescence and…

The socialisation of adolescent boys and girls takes place primarily online in virtual environments, where cyberbullying is one of the greatest current social dangers faced by that age group. Socio-emotional e-competencies (i.e., competencies that apply specifically to online environments) are a protective factor against cyberaggression and…

Background: Friendship quality is crucial for psychological well-being, yet is often lower in persons with intellectual disabilities compared to their peers. This study explores the predictors of friendship quality among adults with mild intellectual disability, focusing on age, gender, living setting, psychiatric traits, and social cognition.…

Bullying victimization is a very common, complex, and potentially damaging form of violence among children and adolescents. Bullying is defined as unwanted, aggressive behavior, which involves a real or perceived social power imbalance. One in 10 public schools reports at least one case of serious violent crime, such as aggressive bullying,…

The COVID-19 pandemic has brought the challenge of online teaching to graduate courses, without prior preparation for students and teachers. In this context, the aim of the study was to identify sociodemographic predictors of difficulty in carrying out online academic activities by graduate students, by region of Brazil, during the COVID-19…

Objective, Participants, & Methods: The COVID-19 pandemic has exacerbated mental health challenges of university students, staff, and faculty alike. We used linear mixed models to examine demographic predictors of, and change over time in, self-reported depression and anxiety symptoms of a cohort of university students and staff/faculty…

Knowledge is an important predictor and outcome of learning and development. Its measurement is challenged by the fact that knowledge can be integrated and homogeneous, or fragmented and heterogeneous, which can change through learning. These characteristics of knowledge are at odds with current standards for test development, demanding a high…

This study aimed to determine whether or not curriculum fidelity can be significantly predicted by certain demographic variables and level of curriculum literacy in elementary school teachers. The study was designed as a relational survey study and involved the participation of 250 elementary school teachers. For data collection, a personal…

Background: Sufficient physical activity (PA) is important to reduce the risk of men developing chronic diseases and to improve mental health. The effectiveness of PA programmes can vary, however, among men. Individual and socio-psychological characteristics may affect the level of men's PA before starting a behaviour change programme as well as…

Objective: Test the hypothesis that smoking, fast-food consumption, and binge drinking were negatively associated with academic performance in Canadian undergraduate students. Participants: Undergraduate students across Canada [n = 411 (335[female gender symbol]) aged: 22 ± 4 years] completed a questionnaire regarding their lifestyle behaviors and…
