Rats cached pieces of cheese on four different arms of an eight-arm radial maze. On a retrieval test given 45min later, rats learned to return to arms where food was cached before arms where food had not been cached. Tests were then performed in which cache sites on one side of the maze were always modified (pilfered or degraded), but cache sites…

Humans find some sounds more pleasing than others; such preferences may underlie our enjoyment of music. To gain insight into the evolutionary origins of these preferences, we explored whether they are present in other animals. We designed a novel method to measure the spontaneous sound preferences of cotton-top tamarins, a species that has been…

Understanding the precursors and early indicators of dyslexia is key to early identification and effective intervention. Now there's a single research volume that brings together the very latest knowledge on the earliest stages of dyslexia and the diverse genetic, neurobiological, and cognitive factors that may contribute to it. Based on findings…

Energy education has been conducted to equip learners with relevant energy conservation knowledge for many years. However, learners seldom put the knowledge into practice and even have few ideas about how to reduce energy consumption. To this end, there is a need to address this issue to improve the efficiency of energy education. One of the…

Food and eating in schools have most often been thought of as utilitarian parts of the day, as distractions, and, for education researchers, as lacking incentives to study or even as objects of derision rather than serious concern. Yet there are good reasons why scholars of education should consider food and food practices. These include the…

Described is a course on animal behavior offered for high school students grade 10-12. The course has a biology prerequisite and includes units on behavior patterns, communication, courtship patterns, territories, and social groups. (SL)

Describes how to measure the daily rhythm of activity (photoperiodism) of small mammals. Three methods for recording information are reviewed including instructions for making a recorder. Includes suggestions for activities and experiments. (PR)

A program at Moorpark Community College, in Moorpark, California, offers a two-and-a-half-year major in Exotic Animal Training and Management. Emphasis is on the practical, everyday handling and training of wild animals. (LBH)

Japan once was a country suffering from undernourishment due to the shortage of food supply during and right after World War. Within a half century, however, Japan became one of the most developed industrial counties and, during the process of the economic development, adopted Western life style and eating habit: the Japanese have, with sufficient…

The ability to select an appropriate motor response by resolving competition among alternative responses plays a major role in cognitive performance. fMRI studies suggest that the development of this skill is related to the maturation of the frontal cortex that underlies the improvement of motor inhibition abilities. However, fMRI cannot…

Velocardiofacial syndrome (VCFS), also known as DiGeorge, conotruncal anomaly face, and Cayler syndromes, is caused by a microdeletion in the long arm of Chromosome 22. We review the history of the syndrome from the first clinical reports almost half a century ago to the current intriguing molecular findings associating genes from the…

The purpose of this study was to investigate seventh grade students' conceptions of global warming and climate change. The study was descriptive in nature and involved the collection of qualitative data from 91 seventh grade students from three different schools in the Midwest, USA. An open response and draw and explain assessment instrument was…

The fear conditioning paradigm is used to investigate the roles of various genes, neurotransmitters, and substrates in the formation of fear learning related to contextual and auditory cues. In the brain, nitric oxide (NO) produced by neuronal nitric oxide synthase (nNOS) functions as a retrograde neuronal messenger that facilitates synaptic…

In this article, the author describes how a visit from a flock of chickens provided inspiration for the children's chicken art. The gentle clucking of the hens, the rooster crowing, and the softness of the feathers all provided rich aural, tactile, visual, and emotional experiences. The experience affirms the importance and value of direct…

Most people are familiar with the concept that animals come in all shapes and sizes and that the body plan of some animals can completely transform during their lifetime. Well-known examples of such complex life cycles of terrestrial animals include butterflies and frogs. Many people are unaware, however, that complex life cycles are exceedingly…
