Happiness is one of the most important parenting goals in today's modern society. To promote a happy childhood, we need to understand what happiness means to children. Contrary to the view that young children may equate happiness with satisfying material desires and experiencing simple pleasures, in this article, I review recent developmental…

Background: The impact of having a disabled brother or sister on siblings' psychological well-being and sibling relationships has been the subject of several research studies.

According to coercion theory (Patterson, 1982, 2016), children's aggression is developed and maintained through transactional processes between parents and their children that unfold over time. The theory provides a model of the behavioral contingencies that explain how parents and children mutually "train" each other to behave in ways…

Adolescents' mental health and academic performance are subjects of paramount interest. Previous studies have revealed a strong association between these constructs during school years. However, there is little evidence about the dual-factor model of mental health, which includes a combination of psychological well-being and distress indicators,…

Fatigue is associated with numerous harmful physical and mental health outcomes. Despite the established relationship between sleep and fatigue, research examining sleep variability within a person (i.e. intraindividual variability; IIV) and fatigue is limited. In addition, the associations between child and parent sleep regarding parent fatigue…

This study used naturalistic audio-visual recordings from early care and education (ECE) settings to examine the associations between toddlers' (76 toddlers, 40 female, M[subscript age] = 32.94 months, SD = 4.92 months) multimodal emotion expressions and emotion-related vocalizations with contingent teacher interventions. Findings indicated a…

This study aimed to understand how mindfulness meditation affects young people by examining its impact on self-regulation, happiness, emotional awareness, and school performance among two groups of school children. A 10-week mindfulness program was conducted by a meditation expert for 552 children aged 4-8 (Group 1) and 287 children aged 9-11…

The purpose of this study was to examine how the members of children's peer groups resemble each other in terms of behavioural and emotional strengths, academic achievement and behaviour at school. The participants were 739 9- to 10-year-old children (354 boys, 385 girls) from 30 Finnish elementary schools. 431 children (241 girls, 190 boys) were…

Background: There is growing interest in research understanding the individual-specific predictors of child callous-unemotional (CU) traits, particularly in early childhood. Objective: This study reviewed evidence from studies that investigated the relationship between early child temperament factors (between 0 and 3 years) and CU traits in…

Summer camp programs provide adolescent counselors with opportunities to work alongside adult staff, aiming to develop critical skills such as communication, responsibility, independence, and teamwork. Growing research supports the value of camp-based developmental relationships through youth-adult partnerships. However, tensions often arise as…

Attendance at preschool represents an important transition, as it is often here that children have their first experience with unfamiliar adults. In this context, several factors can affect children's adjustment. Two important protective factors are the attachment relationship with the teacher and the level of executive functions. We investigate…

This research investigates the influence of color-filtered lighting in relation to biophilic design, specifically within the preschool learning environment where design elements impact early childhood development. Among various architectural design components, research underscores the pivotal role of lighting in affecting children's pleasantness…

Today, digital games are considered important tools for learning, but using them in early childhood education and care (ECEC) has raised the question of educators' roles when children play an educational digital game. The aim of this study was to explore how ECEC educators differed in their attitudes and perceptions toward and ways of supporting…

This study examined longitudinal associations between parental psychological distress (stress and depression) when the child was 2 to 4 years and a child's emotional and behavioural problems at ages 3 to 4, and social functioning (loneliness and social competence) at age 11 in very preterm born children. The participants were Finnish families of…

In this study, we aimed to determine the role of parental praise and child affect in the neural processes underlying parent-child interactions, utilizing functional near-infrared spectroscopy (fNIRS) hyperscanning. We characterized the dynamic changes in interpersonal neural synchrony (INS) between parents and children (4-6 years old, n = 40…
