Children undergo significant changes as they enter secondary school, a time during which their social and academic self-concept is fluid and the pressures to adjust and show positive attitudes and behaviours are intense. Utilising data from the Millennium Cohort Study (Waves 4 and 5) the purpose of this study was two-fold: to examine longitudinal…

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…

Gender-Sexuality Alliances (GSAs) and inclusive school policies and practices that affirm youth with minoritized sexual orientations or gender identities (e.g., lesbian, gay, bisexual, transgender, queer youth; LGBTQ+ youth) are two sources of support for LGBTQ+ youth that could promote school belonging. The current study tested a three-level…

Objectives: The two-fold purpose of this feasibility study was to determine if (a) self-regulated strategy development intervention would improve the writing skills of a child who uses cochlear implants and (b) if self-regulated strategy development intervention would improve the reading comprehension skills of a child who uses cochlear implants.…

High sleep quality has been associated with beneficial outcomes across the life span. Intensive longitudinal studies suggest that these beneficial effects can also be observed on a day-to-day level. However, the dynamic interplay between subjective sleep quality and affective well-being in children's daily life has only rarely been investigated.…

Freestyle-disco is a relatively new and complex competitive dance style that, to our knowledge, has yet to be researched. Thus, the purpose of this research was to explore two fundamental physiological characteristics of exercise in relation to freestyle-disco as a starting-point for future research into the style. From this, the authors hope to…

Two studies ask whether scaffolded children (n = 243, 5-6 years and 9-10 years) recognize that assistance is needed to learn to use complex artifacts. In Study 1, children were asked to learn to use a toy pantograph. While children recognized the need for assistance for indirect knowledge, 70% of scaffolded children claimed that they would have…

The present research aimed to identify and compare playfulness levels of individuals aged 10-14 years engaging in individual and team sports. The sample consisted of 356 participants. We employed a correlational design and used the "Playfulness Scale for 10-14-years-old Children" developed by Hazar as the data collection tool. In data…

While football/soccer is the most influential sport in the world, it is surprising that developmental sequences of forceful kicking have not been adequately described and validated in the literature. The purpose of this study was to explore potential developmental sequences for forceful kicking using a prelongitudinal screening method. Data were…

Children learn words in ambiguous situations, where multiple objects can potentially be referents for a new word. Yet, researchers debate whether children maintain a single word-object hypothesis -- and revise it if falsified by later information -- or whether children establish a network of word-object associations whose relative strengths are…

In this dissertation I report findings from two studies of the literacy abilities of children with Williams syndrome (WS), a genetic disorder associated with intellectual disability. I had two overarching goals: 1) evaluate the applicability of theories of reading and spelling acquisition developed based on typically developing children to…

The implementation of lockdowns that include the closure of educational facilities for face to face teaching has been one of the strategies used internationally to contain the spread of the COVID-19 virus. Research suggests lockdowns are associated with negative impacts on children's psycho-social functioning, Most research, however, has been…

In this study, the authors evaluated the potential role of an activity-based guitar training program on reducing anxiety and providing fulfillment for younger relatives of cancer patients. Ten active members of KHYD (The Society for Relatives of Cancer Patients), between ages 11 and 17 participated in an 8-week guitar education program. The…

Background: Developmental research provides considerable evidence of a strong relationship between verbal and visuospatial working memory (WM) and mathematics ability across age groups. However, little is known about how components of WM (i.e., short-term storage, processing speed, the central executive) might relate to mathematics sub-categories…

Temporal accounts of Developmental Dyslexia (DD) postulate that a timing impairment plays an important role in this learning disorder. However, DD has been associated with timing disorders as well as other motor and cognitive dysfunctions. It is still unclear whether nonverbal timing skills per se may be considered as independent determinants of…
