Interpersonal distance regulation is crucial for successful social interactions. We investigated personal space awareness in Williams syndrome (WS) and autism spectrum disorder (ASD) compared to typical development. Parents reported that individuals with WS and ASD were significantly more likely than those developing typically to invade the…

This study examined individual differences in ADHD symptoms and executive function (EF) in children with Down syndrome (DS) in relation to the dopamine receptor D4 (DRD4) gene, a gene often linked to ADHD in people without DS. Participants included 68 individuals with DS (7-21 years), assessed through laboratory tasks, caregiver reports, and…

We examined concern for others in 22-month-old toddlers with an older sibling with autism spectrum disorder (ASD) and low risk typically-developing toddlers with older siblings. Responses to a crying infant and an adult social partner who pretended to hurt her finger were coded. Children with a later diagnosis of ASD showed limited empathic…

Learning about stem cells within the context of treating pet illness or injury is an additional way for teachers to discuss the integration of science, technology, and veterinary medicine. We explain how practitioners in veterinary medicine harvest animal stem cells from adipose (fat) tissue in treating pet illness or injury. Further, we narrate…

The role of parenting in the development of criminal behavior has been the source of a vast amount of research, with the majority of studies detecting statistically significant associations between dimensions of parenting and measures of criminal involvement. An emerging group of scholars, however, has drawn attention to the methodological…

In 1995, Nelson explored the relation between early memory development and corresponding changes in brain development, and conceptualized this knowledge in a coherent theoretical framework (Nelson, 1995). In their review, Jabe's and Nelson provide an update of Nelson's 1995 cognitive neuroscience model of human memory development. In this article,…

Current evidence suggests the phenotype of autism spectrum disorder to be driven by a complex interaction of genetic and environmental factors impacting onto brain maturation, synaptic function, and cortical networks. However, findings are heterogeneous, and the exact neurobiological pathways of autism spectrum disorder still remain poorly…

Memories that last a lifetime are thought to be stored, at least in part, as persistent enhancement of the strength of particular synapses. The synaptic mechanism of these persistent changes, late long-term potentiation (L-LTP), depends on the state and number of specific synaptic proteins. Synaptic proteins, however, have limited dwell times due…

Few studies have examined the relationship between autistic symptomatology and competence in independent living skills in adolescents and young adults with fragile X syndrome (FXS). In this study, 70 individuals with FXS, aged 15-25 years, and 35 matched controls were administered direct measures of independent living skills and autistic…

We investigated executive functioning in 25 children and adolescents with Prader-Willi syndrome (PWS) on the Behavior Rating Inventory of Executive Function (BRIEF). Significant deficits emerged, with mean scores on all but two scales reaching levels of clinical significance (T score = 65). Older children tended to have higher scores than younger…

Access to science information via communications in the media is rapidly becoming a central means for the public to gain knowledge about scientific advancements. However, little is known about what content knowledge is essential for understanding issues presented in news media. Very few empirical studies attempt to bridge science communication and…

Teachers are being challenged to engage students in ways that will elevate student interest and understanding of concepts in science and encourage students to gather evidence to support what we know about science. It is critical for teachers to have budget-friendly, supporting activities that are aligned with current educational standards, that…

For the past two centuries deaf people in the United States have faced more or less intense skepticism about their marriages to each other, largely due to fears of inherited deafness. These fears, while always present, have waxed and waned over time, becoming most prominent during the eugenics era of the late nineteenth and early twentieth…

In an effort to address K-8 teacher confidence in STEM and increase basic genetics knowledge to a level consistent with its importance in society, we have developed, implemented, and evaluated a 7-day teacher professional development workshop. The overarching goal of our workshop is to facilitate the implementation of innovative DNA-based…

Across the globe, from the very wealthy continents of North America to Europe to Australia, the phenomenon of migrant and immigrant students outperforming native students are observed and documented. Some migrants and immigrants from China, the Philippines, India, Russia, Africa, and the Caribbean are reportedly achieving higher test scores than…
