Background: There is sparse literature about problem behaviour in young children with Williams syndrome (WS) and little consideration of the perspectives of multiple respondents. Methods: Problem behaviour of 35 children with WS ages 2 to 6 was examined based on both parent and teacher report using the Achenbach preschool forms. Results: The most…

Background: On 14 May 2013, Angelina Jolie (AJ), revealed herself to be the carrier of a BReast CAncer 1 (BRCA1) gene mutation and announced her decision to undergo a prophylactic mastectomy, followed by a laparoscopic bilateral salpingo-oophorectomy. This review explores the impact of the "Angelina Jolie Effect" in order to reveal…

In the context of what are often highly compartmentalised curriculum requirements, this article considers the cyclical nature of the acquisition and transfer of knowledge in the education system in relation to those questions that transcend individual subjects as set out in traditional curriculum divisions. It also considers the detrimental…

Researchers and pollsters still debate the acceptance of genetic engineering technology among U.S. adults, and continue to assess their knowledge as part of this research. While decision-making may not rely entirely on knowledge, querying opinions and perceptions rely on public understanding of genetic engineering terms. Experience with…

The present investigation explored long-term relationships of behavioral symptoms of adolescents and adults with developmental disabilities with the mental health of their mothers. Fragile X premutation carrier mothers of an adolescent or adult child with fragile X syndrome (n = 95), and mothers of a grown child with autism (n = 213) were…

Purpose: Variability in the timing of infant developmental milestones is poorly understood. We used a twin analysis to estimate genetic and environmental influences on motor development and activity levels in infancy. Method: Data were from the Gemini Study, a twin birth cohort of 2,402 families with twins born in the United Kingdom in 2007.…

Identity formation is a key developmental task in adolescence. Although many adolescents in modern societies face issues of identity, there are substantial individual differences in identity exploration and commitment. Little is known about the origins of these individual differences. The current study investigated the genetic and environmental…

The present study sought to examine the relationship between Chinese high school students' academic self-efficacy and their academic-related boredom. Another objective was to explore the moderating effects of mono-amine-oxidase type A ("MAOA") gene polymorphism on this relationship. In a sample of 514 Chinese high school students, we…

Recent studies have suggested that sensory processing atypicalities may share genetic influences with autism spectrum disorder (ASD). To further investigate this, the adolescent/adult sensory profile (AASP) questionnaire was distributed to 85 parents of typically developing children (P-TD), 121 parents from simplex ASD families (SPX), and 54…

Students have difficulties understanding the crossing-over field concept in genetic courses because within the concept of crossing-over there are facts and problems that are difficult to solve as well as the absence of valid, practical, and effective student worksheets. So that the learning process is complete, activities and student learning…

Formative assessment in science has long been reported to support students' scientific understanding. It involves teachers gathering assessment evidence, interpreting it in the light of learning goals and providing feedback to bridge the gap between students' current state of understanding and the desired educational goals. This study examines how…

We studied 261 ADHD probands and 354 of their siblings to assess quantitative trait loci associated with autism spectrum disorder symptoms (as measured by the Children's Social Behavior Questionnaire (CSBQ) using a genome-wide linkage approach, followed by locus-wide association analysis. A genome-wide significant locus for the CSBQ subscale…

Precollegiate education has paid little attention to the bioethical underpinning of recent innovations. Without a deliberate commitment to bioethical education, confusion and divisiveness regarding genetic testing are likely to challenge harmony in families and further polarize the already fragmented society. This article presents the following…

Habituation is the simplest form of learning, but we know little about the transcriptional mechanisms that encode long-term habituation memory. A key obstacle is that habituation is relatively stimulus-specific and is thus encoded in small sets of neurons, providing poor signal/noise ratios for transcriptional analysis. To overcome this obstacle,…

Humans and many other species selectively attend to stimuli or stimulus dimensions--but why should an animal constrain information input in this way? To investigate the adaptive functions of attention, we used a genetic algorithm to evolve simple connectionist networks that had to make categorization decisions in a variety of environmental…
