CRISPR is a technique increasingly used in the laboratory for both fundamental and applied research. We designed and implemented a lab experience for undergraduates to carry out CRISPR technology in the lab, and knockout the wing patterning genes "optix" and "WntA" in "Vanessa cardui" butterflies. Students obtained…

Empirical evidence suggests a phonological loop deficit associated with Down syndrome. A trisomy 21 may be associated with a narrowing of visual attention to fewer than four objects at a time too. In a study with computer tachistoscopy, the hypothesis was confirmed in all 194 persons with trisomy 21. The subitising limit of persons with trisomy 21…

Despite the importance of self-control for well-being and adjustment, its development from early childhood to early adolescence has been relatively understudied. We addressed the development of mother-reported self-control in what is likely the largest and longest longitudinal twin study of the topic to this day (N = 1889 individual children with…

Undergraduate research experience is critical to success in postgraduate research settings. The recent movement away from "cookbook" style laboratories to course-based undergraduate research experiences (CUREs) in undergraduate laboratories has allowed universities to provide inclusive research experience while bypassing the limitations…

Understanding genetic variation is important in science education and in today's world, for example, to respond to the changing environment and face species extinction. However, students often need help to grasp its importance and complexities due to fragmented knowledge and a need for more awareness of how different concepts are interconnected.…

We propose genetic social psychology as a theoretical framework to render intelligible both the suppression of the expression of prejudice and prejudice reduction in childhood. In particular, we explore the role of positive in-group norms in prejudice reduction in childhood and adolescence and their interplay with realistic and symbolic threats…

Background: Social communication skills are critical for full participation in social activities in primary life contexts for adolescents and young adults with neurodevelopmental disorders. Method: Two young adults with Prader Willi syndrome participated in an online socialisation programme with elderly and adolescent conversational partners. We…

Individuals with autism spectrum disorder present with difficulties in social communication, restricted interests or behaviors and other co-morbidities. About 2 to 10% of cases of autism have a genetic cause, and Fragile X Syndrome (FXS) is reported in 0 to 6.5% of individuals with autism. However, the FXS and premutation prevalence among Filipino…

There is an emphasis on survival-based selection in biology education that can allow students to neglect other important evolutionary components, such as sexual selection, reproduction, and inheritance. Student understanding of the role of reproduction in evolution is as important as student understanding of the role of survival. Limiting…

Individuals with Sex Chromosome Trisomies (SCT; XXX, XXY, XYY) have an increased vulnerability for developing challenges in social adaptive functioning. The present study investigates social interaction behavior in the context of varying social load, and Autism Spectrum Disorder (ASD) symptomatology in young children aged 1-7.5 years old, with SCT…

In 1623, Hernando Ruiz de Alarcón, a parish priest in Atenango, Mexico, was commissioned by his archbishop to record Nahua beliefs and healing practices for the purpose of denouncing their superstitions and demonic magic. His "Treatise on the Heathen Superstitions That Today Live Among the Indians Native to This New Spain," 1629…

Demonstrating how race is socially constructed has been a core sociological objective, yet many individuals continue to hold essentialist and other concepts of what races are and how to account for group differences. These conceptualizations have crucial consequences for intergroup attitudes, support for social policies, and structures of…

The activity presented here is about an approximate or order-of-magnitude approach to information technology on the nano level, dealing in particular with the genetic code. Based on "There's Plenty of Room at the Bottom", the famous and visionary paper by Richard Feynman, the activity provides insight into a core concept of nanoscience…

Intra-individual response time variability (IIRTV) during cognitive performance is increasingly recognized as an important indicator of attentional control (AC) and related brain region function. However, what determinants contribute to preschoolers' IIRTV received little attention. The present study explored the interaction of dopaminergic…

Analogies are used to make abstract topics meaningful and more easily comprehensible to learners. Incorporating simple analogies into STEM classrooms is a fairly common practice, but the analogies are typically generated and explained by the instructor for the learners. We hypothesize that challenging learners to create complex, extended analogies…
