Cats in a Puzzle Box

Cats placed in a version of the Thorndike problem box with transparent wall learn to press against upright pole to open door and obtain food. Each finally learns to push against pole in own stereotyped manner, having eliminated most needless movements in course of learning. Black and White/Monochrome; silent. 1938 E.R. Guthrie and G.P. Horton.

Social Reaction of Imprinted Ducklings

Shows that newly hatched ducklings imprint to various moving stimuli in place of the mother and can be conditioned to perform specific actions using these stimuli as reinforcement. Covers the learning process, extinction, and the ducklings' own behavior as affected by learned responses. H. Hoffman.

Reproductive Behavior of the Brook Trout (Salvelinus Fontinalis)

Demonstrates all behavioral activity leading up to, including, and following the spawning of brook trout in their natural environment. Opening with phenologic environmental changes related to the spawning period and color intensification in the male, the program then depicts initiatory cutting and probing of the female and her preparation of the redd, agonistic competitive behavior of males, the spawning act, and the postnuptial dance. Frequent use of slow-motion photography and a telephoto lens adds to the clarity of detail. Produced by Dr. Robert L. Butler of Penn State University.

A Trout Stream in Winter

A study of the behavior of trout and their winter environment conducted at a field station in the Sierra Nevadas. Includes reproductive behavior of brook trout, spawning of rainbow trout, and the dangers posed to stream ecology by low snowfall in a high snowpack area and by the formation of frazil and anchor ice. Produced by Dr. Vernon Hawthorne of the University of California, Berkeley, and by Dr. Robert L. Butler of The Pennsylvania State University.

On the Trail of Pennsylvania Black Bears

White-Tailed Deer: Pennsylvania's Most Controversial Animal

L361 64VH 1990. This video explores the controversy surrounding Pennsylvania's white-tailed deer through interviews with hunters, farmers, foresters, managers, and others whose lives are directly affected by the species. It explains current management strategies and offers suggestions for reducing conflicts.

How Birds Survive the Winter

Documents the behaviors of nonmigratory birds that enable them to survive in a cold northern climate, including breathing prewarmed air, protecting extremities, fluffing feathers, shivering, countercurrent heat exchange, sun basking, burrowing under the snow, using natural and manmade shelter, communal roosting, and torpor. Recorded during the winter months in central Pennsylvania. Narrated by Peg French. Written and produced by Allan Rose, Jr., and Royal Alvis.

Sexual Behavior in the American Bison

Illustrates the basic patterns of sexual behavior in adult male and female bison. Many of the patterns are interpreted in terms of the selective advantage they confer on the individual bison. Dale F. Lott.

Aggressive Behavior in Mature Male American Bison

Presents patterns of aggressive behavior in a free-ranging herd of American bison, including straight-on threat, broadside threat, nod, bellowing, and wallowing. Shows submission patterns, with emphasis on the mounting-intention movement, in sexual and aggressive interactions. Interprets the adaptive value of patterns that substitute for fighting as a reduction in risk of injury and expenditure of energy. Directed by Dale Lott.

Constitutional and Environmental Interactions in Rearing Four Breeds of Dogs

1962 produced by D.G. Freedman. Illustrates procedures and findings of an experiment in which inbred strains of basenjis, Shetland sheepdogs, beagles, and wire-haired terriers are raised in either "indulged" or "disciplined" fashion following weaning at three weeks of age. The results demonstrate the interaction of constitutional type (breed) and mode of rearing

Visual Form Discrimination in the Cat

PCR-32 1933 silent K.U. Smith Cats are faced with two or more windows with cards, each mounted over a foot-lever which the animal presses in making a discrimination. The animals shown in the film have been trained to respond positively to a triangle. Cats trained in a "paired" stimulus situation transfer readily to the "unpaired" situations. The film shows a series of initial responses for each of several cats when such transfers are required. An animal trained to select a triangle when it is presented with circles will continue to select the triangle with a high percentage of accuracy. A demonstration is presented showing how this apparatus can be used to measure visual acuity.

Mechanisms of Air Ventilation in Labyrinth Fishes

Labyrinth fishes have accessory breathing organs that adapt them for survival in low-oxygen and even oxygen-free water. This tape features three species of the Anabantoid family (the African bush fish, the gourami, and the climbing perch), and employs live-action and slow-motion photography, graphics and models, dissection, and X-ray cinematography to demonstrate the process. Produced by the Institut fur den Wissenschaftlichen Film.
