Phenotypic elements of autism spectrum disorder can be masked by attention-deficit/hyperactivity disorder symptoms, potentially leading to a misdiagnosis or delaying an autism spectrum disorder diagnosis. This study explored differences in the age of autism spectrum disorder diagnosis between participants with previously diagnosed…

Age-related behavioural change in Cornelia de Lange syndrome is poorly understood. We report a 7 year follow-up study of adaptive behaviour, autism spectrum disorder symptomatology, language skills and behavioural characteristics in 30 individuals with Cornelia de Lange syndrome, compared with 18 individuals with Cri du Chat syndrome. The…

Integrated STEM education holds the promise for students' meaningful science instruction. However, the implementation of integrated STEM-based approaches for science learning might be difficult for teachers due to the lack of expertise and instructional materials. Therefore, this study focused on the preparation and validation of an integrated…

English language readers rarely get glimpses of the state of autism research in China. Given the seriousness of autism, the population of China, and the potential for theoretically interesting cross-cultural insights, we provide a broad survey of research carried out in China on childhood autism. Four themes are considered: etiology, diagnosis,…

A lesson plan on the phylum Tardigrada is presented in a storytelling workbook that introduces the evolutionary concepts of adaptive radiation, speciation, divergence, and "tree-thinking" through narrative, transitional art, contemplative coloring, and data searches, which can be enhanced with microscopy wet labs. Students gain insight…

Dealing with multiple external representations (MERs) in science education is the key to students' understanding of science communication and becoming scientifically literate. It is generally accepted that learning scientific concepts, processes, and principles requires understanding and interacting with MERs. Science can be understood as a…

Instructional material is an integral part of teaching and learning process. Validating instructional materials is imperative to ensure quality before widespread utilization. This study validated the developed Gamified Instructional Material (GIM) in genetics for grade 12 STEM students. It employed the descriptive-developmental research design…

Background: The perceptions of individuals with Down syndrome are conspicuously absent in discussions about the use of prenatal testing. Method: Eight individuals with Down syndrome were interviewed about their views and experience of the topic of prenatal testing. Results: Interpretative phenomenological analysis revealed two major themes with…

This study investigated behavioral indicators of social fear in preschool boys with fragile X syndrome (FXS) with a low degree of autism spectrum disorder (ASD) symptoms (FXS-Low; n = 29), FXS with elevated ASD symptoms (FXS-High; n = 25), idiopathic ASD (iASD; n = 11), and typical development (TD; n = 36). Gaze avoidance, escape behaviors, and…

Atypical visual perceptual skills are thought to underlie unusual visual attention in autism spectrum disorders. We assessed whether individual differences in visual processing skills scaled with quantitative traits associated with the broader autism phenotype (BAP). Visual perception was assessed using the Figure-ground subtest of the Test of…

To identify similarities and differences in the behavioral profile of children with Williams syndrome from Spain (n = 53) and the United States (n = 145), we asked parents of 6- to 14-year-olds with Williams syndrome to complete the Child Behavior Checklist 6-18. The distribution of raw scores was significantly higher for the Spanish sample than…

Several studies have reported declines in adaptive behavior amongst children with fragile X syndrome (FXS) starting in middle childhood. We examined the effects of maternal responsivity on adaptive behavior in 55 children with FXS visited 5-6 times in their homes from early through middle childhood. Our analyses indicated that sustained maternal…

Eukaryotes use proteins to carefully package and compact their genomes to fit into the nuclei of their individual cells. Nucleosomes are the primary level of compaction. Nucleosomes are formed when DNA wraps around an octamer of histone proteins and a nucleosome's position can limit access to genetic regulatory elements. Therefore, nucleosomes…

This article offers a philosophical-empirical account of embodied skilful performance in the practice of plant biotechnology. Drawing on the work of Merleau-Ponty and others, we elaborate how skilful performance emerges from and through reciprocal relations encompassing the body-in-the-world and the world-in-the-body. The contribution of this…

Parent depressive symptomatology is robust risk factor for externalizing behavior in childhood (Goodman et al., 2011). Although the precise mechanisms underlying this association have yet to be fully illuminated, there is some evidence that parent depression can impact externalizing behavior via both genetic and environmental pathways. In the…
