Differentiation hypotheses concern changes in the structural organization of cognitive abilities that depend on the level of general intelligence (ability differentiation) or age (developmental differentiation). Part 1 of this article presents a review of the literature on ability and developmental differentiation effects in children, revealing…

Major developmental theories been a resource to early childhood education researchers and educators. They help to explain how child development unfolds, sources of vulnerability and protection that influences child development, and how the course of development may be altered by prevention and intervention efforts. Understanding factors which may…

Background: Borderline personality symptoms include emotional dysregulation, high levels of impulsivity leading to self-harm and suicidality, an unstable sense of self, fears of abandonment, extremely turbulent relationships, and psychic pain. They are considered to disrupt normative adolescent development however their unique contribution to…

Developmental scholars, parents, and policymakers alike have long heralded the opening years of life as disproportionately influential. Recent work on adolescence has revealed, however, greater influence of these later years--but without considering how experience during these two periods interact. We address this issue by studying adverse…

Purpose: We aimed to provide novel information on utterance duration as it relates to vocal type, facial affect, gaze direction, and age in the prelinguistic/early linguistic infant. Method: Infant utterances were analyzed from longitudinal recordings of 15 infants at 8, 10, 12, 14, and 16 months of age. Utterance durations were measured and coded…

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…

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…

Few studies have investigated associations of milestone development in early childhood with intelligence in adulthood in typically developing children. The current study is an extension of 2 previous studies on smaller samples and investigated associations of age at attainment of 32 developmental milestones attained between 0 and 3 years of age…

Does mothers' employment predict the subsequent maternal employment of their daughters? Social learning theory suggests that modeling should increase under more positive relationship conditions. We examined the congruence between mothers' maternal employment and daughters' maternal employment longitudinally across 4 periods of parenthood and as a…

The current investigation examined the developmental changes involved in processing semantic context in auditorily presented sentences, as well as underlying attentional and suppression mechanisms. Thirty-nine typically developing school-aged children aged 6;0-14;0 years participated in the current cross-sectional sentential auditory word…

This study examined changes in subjective well-being (SWB) during early adolescence (seventh grade-ninth grade). We treated SWB as a latent variable, which was measured by life satisfaction, negative emotions, and positive emotions, and employed a growth curve model-to-model change. Aspects of family structure (e.g., parental marital status and…

Knowledge about one's own cognitive processes is the basis for the monitoring and regulation of learning processes for effective reading comprehension. Taking verbal cognitive ability into account, the present study aimed to examine the developmental trajectories of reading comprehension and declarative metacognitive knowledge and their…

Throughout childhood and adolescence, humans experience marked changes in cortical structure and cognitive ability. Cortical thickness and surface area, in particular, have been associated with cognitive ability. Here we ask the question: What are the time-related associations between cognitive changes and cortical structure maturation.…

The research completed by the authors into the teaching and learning of evolution and inheritance (2014 to 2018) seeks to understand the demands made by the revised National Curriculum in England (DfE, 2015) and to offer support. The commitment of the authors to applied research assumes more useful outcomes are likely when studies are conducted…

The only consistency with children, with and without disabilities, is that they are inconsistent. Much of a child's behavior is adult controlled by their reaction, methods used, and consistency in support and discipline. When adults change the way they respond to the child's behaviors, the child gradually will learn to modify their behavior.…
