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…

We describe a structured inquiry laboratory exercise that examines transcriptional regulation of the "NOS2" gene under conditions that simulate the inflammatory response in macrophages. Using quantitative PCR and the comparative C[subscript T] method, students are able determine whether transcriptional activation of "NOS2"…

Outstanding skills, including special isolated skills (SIS) and perceptual peaks (PP) are frequent features of autism. However, their reported prevalence varies between studies and their co-occurrence is unknown. We determined the prevalence of SIS in a large group of 254 autistic individuals and searched for PP in 46 of these autistic individuals…

In this classroom activity, students build a phylogeny for woody plant species based on the morphology of their twigs. Using any available twigs, students can practice the process of cladistics to test evolutionary hypotheses for real organisms. They identify homologous characters, determine polarity through outgroup comparison, and construct a…

Previous studies have shown that zinc deficiency leads to apoptosis of neuronal precursor cells in vivo and in vitro. In addition to the role of p53 as a nuclear transcription factor in zinc deficient cultured human neuronal precursors (NT-2), we have now identified the translocation of phosphorylated p53 to the mitochondria and p53-dependent…

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…

Purpose: To assess strengths and weaknesses of the reading level (RL) match approach and its potential to generate insights regarding the cognitive foundations of reading ability and disability. Method: We applied RL-match design to a sample of 2nd-6th graders reading a consistent orthography, Russian, using an "extreme phenotype"…

The correct labeling of seafood is important to protect nature and the rights of consumers. Given the certainty that the resources of the sea are not inexhaustible, only strict regulations and the implementation of sustainable fishing systems and reliable and traceable marketing systems can help ensure the long-term sustainability of fishery…

There is great potential in making assessment and learning complementary. In this study, we investigated the feasibility of developing a desktop virtual reality (VR) laboratory simulation on the topic of genetics, with integrated assessment using multiple choice questions based on item response theory (IRT) and feedback based on the cognitive…

The 2018 Cleveland conference screened a documentary film titled "Symbiotic Earth: How Lynn Margulis Rocked the Boat and Started a Scientific Revolution." NAMTA conference participants enjoyed this memorable premier event in honor of Lynn Margulis, her symbiotic worldview, and her intimate community of scientific stars. This article is…

This quantitatively driven sequential mixed methods study articulates the role of theory in mixed methods research and assesses the contribution of a mixed methods design to examining gender differences in men and women's genetic testing decisions and the psychosocial factors impacting health-seeking behaviors post-testing. A quantitative online…

Objective: To determine individual and group patient ideas and priorities regarding ways to enhance their own health care while providing a supportive environment including a clinical lipidologist and other medical experts. The intent was to transform these ideas and priorities into hypotheses for future research while enhancing current health…

The current study presents an evaluation of the laboratory instructional tasks prepared based on innovative teaching approaches (research-inquiry, problem solving, project, argumentation and web-based interdisciplinary learning approaches) designed to enhance science teachers' biotechnology knowledge, awareness and laboratory experiences. The…

Objective: This study examined the moderating and mediating effects of perceived social support on the association between precollege sexual assault (SA) and college-onset SA. Participants: A representative sample of 6,132 undergraduates. Methods: The PLUM procedure in SPSS was used to test the moderation model, with individual regressions…
