This article discusses how real research on Down syndrome, being done in a lab at Indiana University-Purdue University Indianapolis (IUPUI), was incorporated into a laboratory activity for middle school students. The activity asked students to evaluate real evidence from the research laboratory of a GK-12 fellow (a graduate student funded by the…

Concerns are growing regarding the availability of sustainable energy sources due to a rapidly growing human population and a better understanding of climate change. In recent years, the United States has focused much attention on developing domestic energy sources, which include coal-bed methane (CBM). There are vast deposits of the natural gas…

In 2007, the United Animal Nations (UAN) launched the Humane Education Ambassador Readers (HEAR), an innovation that focused on mitigation of animal suffering through education. In the HEAR program, adult volunteers read carefully selected story books to children in grades 3-6 in schools or other educational settings, and hold discussions with the…

In daily activities, humans must attend and respond to a range of important items and inhibit and not respond to unimportant distractions. Our current understanding of these processes is largely based on perceptually simple stimuli. This study investigates the interaction of conceptual-semantic categorization and inhibitory processing using Event…

Helplessness, a belief that the world is not subject to behavioral control, has long been central to our understanding of depression, and has influenced cognitive theories, animal models and behavioral treatments. However, despite its importance, there is no fully accepted definition of helplessness or behavioral control in psychology or…

"Ducks in the Flow, Where Did They Go?" represents a fusion of language, arts and science. Offering both a story of discovery and factual science content, this hybrid storybook/textbook promotes literacy on several fronts: ocean principles, general science, and language/arts. A step up from the average text or reference book, "Ducks in the Flow"…

While the ethical dimension of human-animal relationships has become a legitimate, rich subject for contemporary moral philosophers, scholars of moral education, and to a large extent, philosophers of education, have remained surprisingly silent on this subject. The primary purpose of this essay is to illustrate the relationship between the moral…

The network society has a major impact on knowledge systems, and in agricultural and rural development. It has changed relationships between actors such as farmers, extension workers, researchers, policy-makers, businessmen and consumers. These changes require different language, concepts and tools compared to the time that it was thought that…

This article examines doctoral student identity development in regard to engagement with research practices. Using animal research as a contextual lens, it considers how students develop an identity congruent to their perception of the community which facilitates their social and cognitive activities. The shared, interpretive understanding among…

Current medical curricula devote scarce time for practical activities on digestive physiology, despite frequent misconceptions about dyspepsia and dysmotility phenomena. Thus, we designed a hands-on activity followed by a small-group discussion on gut motility. Male awake rats were randomly submitted to insulin, control, or hypertonic protocols.…

This article discusses the Beyond the Walls outdoor education program at The Franklin Schools in Rockville, Maryland. Under the expert guidance of Maryland outdoor education specialist Amy Beam, Franklin's staff has been guided to reconnect to the landscape, understand native plants and animals, and reclaim a sense of gratitude for the environment…

The game of Matching Pennies (MP), a simplified version of the more popular Rock, Papers, Scissors, schematically represents competitions between organisms with incentives to predict each other's behavior. Optimal performance in iterated MP competitions involves the production of random choice patterns and the detection of nonrandomness in the…

There is evidence suggesting aggression may be a positive reinforcer in many species. However, only a few studies have examined the characteristics of aggression as a positive reinforcer in mice. Four types of reinforcement schedules were examined in the current experiment using male Swiss CFW albino mice in a resident-intruder model of aggression…

We employed a triadic comparison task in patients with Alzheimer's disease (AD) and healthy controls to contrast (a) multidimensional scaling (MDS) and accuracy-based assessments of semantic memory, and (b) degraded-store versus degraded-access accounts of semantic impairment in Alzheimer's disease (AD). Similar to other studies using triadic…

Adults, preschool children, and nonhuman primates detect and categorize food objects according to substance information, conveyed primarily by color and texture. In contrast, they perceive and categorize artifacts primarily by shape and rigidity. The present experiments investigated the origins of this distinction. Using a looking time procedure,…
