Explains how to use bats to introduce different biological concepts such as classification and phylogeny, altruistic behavior, flight, coevolution, or physiological adaptations. Discusses common myths regarding bats and provides information on additional classroom materials. (YDS)

This brief statement supports more research on the linguistic and cognitive abilities of animals, particularly primates, and sees direct applicability of such research to language learning by humans with mental retardation who have not learned to speak. (DB)

Notes that rodents and rabbits share many characteristics that make them suitable classroom pets and gives background information on rabbits, guinea pigs, hamsters, and gerbils. Offers advice on buying a classroom pet, the pet's home, feeding, helping the children handle the pet, and pet health and family planning. (TJQ)

Presents an example of an authentic inquiry-based investigation of living organisms that can be easily performed in a school setting or students' neighborhood using pillbugs. Students observe, ask questions, collect data, classify and compare, measure, and analyze data to draw conclusions about pillbug behavior. (SAH)

Investigates children's knowledge about animals by examining the mental models they reveal through their talk when they see animal representations. Presents a study in which representations were provided by robotic models in a museum, preserved animals in a museum, and preserved animals borrowed from a museum and presented in a school setting.…

In Experiment 1, 10 pigeons were exposed to a successive symbolic matching-to-sample procedure in which the sample was generated by the pigeons' own behavior. Each trial began with both response keys illuminated white, one being the "correct" key and the other the "incorrect" key. The pigeons had no way of discriminating which key was correct and…

Increases in regulatory oversight of animal research require verification of effects of standard practices. There are no formal guidelines for establishing free-feeding weights in adult pigeons. In the present study, pigeons were obtained from a commercial supplier, weighed upon arrival, and then held in quarantine for 7 days with free access to…

The present experiment arranged a series of inverted U-shaped feedback functions relating reinforcer rate to response rate to test whether responding was consistent with an optimization account or with a one-to-one relation of response rate to reinforcer rate such as linear system theory's rate equation or Herrnstein's hyperbola. Reinforcer rate…

Identity matching-to-sample has been difficult to demonstrate in rats, but most studies have used visual stimuli. There is evidence that rats can acquire complex forms of olfactory stimulus control, and the present study explored the possibility that identity matching might be facilitated in rats if olfactory stimuli were used. Four rats were…

It is often said that a dog is a best friend. In fact, after cattle, dogs are the oldest domesticated animals. Dogs have lived with humans for over 10,000 years and have been selectively bred for various types of domestication. Domesticated dogs have performed many roles in society throughout history-rescue dogs, hunting dogs, guide dogs, and…

In Experiment 1, we trained four pigeons to concurrently discriminate displays of 16 same icons (16S) from displays of 16 different icons (16D) as well as between displays of same icons (16S) from displays that contained 15 same icons and one different icon (15S:1D). The birds rapidly learned to discriminate 16S vs. 16D displays, but they failed…

Few people realize that coyotes prowl the country's major urban areas. By tracking them on their turf, one Boston-area high school teacher and his students are helping scientists to learn more about the oft-misunderstood animals. Here, the author features David Eatough, a science teacher at Revere High School just north of Boston, and his…

Using a context discrimination procedure and rats as the subjects, the formation of context-dependent aversions to novel and familiar fluids was investigated. Experiment 1 revealed that context dependency could be established to a novel fluid (saccharin) after three cycles of context discrimination training and that the acquired context dependency…

CPEB is a sequence-specific RNA binding protein that regulates translation at synapses. In neurons of CPEB knockout mice, synaptic efficacy is reduced. Here, we have performed a battery of behavioral tests and find that relative to wild-type animals, CPEB knockout mice, although similar on many baseline behaviors, have reduced extinction of…

Decreases in behavioral investigation of novel stimuli over time may be mediated by a variety of factors including changes in attention, internal state, and motivation. Sensory cortical adaptation, a decrease in sensory cortical responsiveness over prolonged stimulation, may also play a role. In olfaction, metabotropic glutamate receptors on…
