The mature visual system condenses complex scenes into simple summary statistics (e.g., average size, location, orientation, etc.). However, children, often perform poorly on perceptual averaging tasks. Children's difficulties are typically thought to represent the suboptimal implementation of an adult-like strategy. This paper examines another…

Background: Although previous research indicates an association between school connectedness and adolescents' sleep quality, its causal direction has not been determined. This study used a 2-wave cross-lagged panel analysis to explore the likely causal direction between these 2 constructs. Methods: Participants were 888 Chinese adolescents (43.80%…

This study compared the temporal measurements of stop consonants in 29 three- to six-year-old Mandarin-speaking children and 12 Mandarin-speaking adults. Each participant produced 18 Mandarin disyllabic words which contained six stop consonants /p, p?, t, t?, k, k?/ each followed by three vowels /a, i, u/ at the word-initial position in the first…

The purpose of this study was to examine the letter-writing ability of preschool children aged 3-5 years and the relationship between early literacy skills (i.e., alphabet knowledge, phonological awareness, and name writing) and letter-writing ability. Thirty-six children were individually assessed on letter writing and early literacy skills…

Literature has indicated conflicting results regarding the relationship between grasp patterns and legible handwriting. Historically, the dynamic tripod grasp was viewed as the gold standard, but more recent literature indicates that grasp may not have as much of an effect on handwriting legibility as once thought. The purpose of this study is to…

The practice of peer assessment has been widely recommended for use in physical education (PE) classes. However, it is unknown how accurately students in lower elementary grades can assess peers' performance. Therefore, this study examined the accuracy at which students in lower elementary PE perform peer assessments of a throwing skill. Students…

Efficient attention control is fundamental for infant cognitive development, but its early precursors are not well understood. This study investigated whether dyadic visual attention during parent-infant interactions at 5 months of age predicts the ability to control attention at 11 months of age (N = 55). Total duration of mutual gaze (MG) was…

Collaborative group work has been recognized as a way of fostering the development of metacognition and self-regulation. Moreover, it has been claimed that these regulatory processes have an interpersonal level in which the regulation of the activity is shared with others (Iiskala et al., 2004). There has also been a considerable body of research…

Symptoms of anxiety and depression are commonly comorbid and partially share a genetic etiology. Mean levels of anxiety and depression increase over the transition to adolescence, particularly in girls, suggesting a possible role of pubertal development in the activation of underlying genetic risks. The current study examined how genetic and…

Cognitive ability and spelling predictors of written expression were examined between gender groups as well as across age and writing skill levels using quantile regression with the Kaufman Assessment Battery for Children--Second Edition and the Kaufman Test of Educational Achievement--Second Edition conormed standardization sample data (N =…

The medial prefrontal cortex (mPFC) plays a critical role in complex brain functions including decision-making, integration of emotional, and cognitive aspects in memory processing and memory consolidation. Because relatively little is known about the molecular mechanisms underlying its development, we quantified rat mPFC basal expression levels…

The aim of this study was to analyse the existence of differences in lexical development as a function of day care attendance and maternal education. Data were collected using the MacArthur-Bates Communicative Development Inventory: Words and Sentences. The reports of 2084 toddlers were analysed. The results for toddlers older than 24 months…

The process of thinking in and about models as a scientific practice should be integrated into science teaching and learning. Empirical studies show that students see models primarily in their role as media to facilitate content learning while rarely appreciating models as instruments of scientists which allow the deduction and the testing of…

Voice hygiene is an important part of voice training process, so voice hygiene should be taken care for a healthy voice. This study which is conducted to evaluate voice hygiene of secondary school students who are at voice change period at 7th and 8th grade is a scanning model. Study group consists of 297 students in total, 142 male and 155 female…

To engage in discussions of artwork meaning is to engage in critical reasoning, a factor that is central to the interpretation of artworks in the art classroom. While this may appear as a common-sense claim that reflects the tacit assumptions most art educators have about students' critical dispositions in art, it is also evident that little is…
