The functions of pituitary and sex hormones in the production of muscle in animals are discussed. A mechanism for hormone action is suggested. (LC)

Discusses the consequences of severe malnutrition in young experimental animals. Development of the brain is permanently impaired. Studies of the effects of malnutrition on children are included. (This paper was presented at the Eighth Annual Lecture of the Merrill-Palmer Historical Library in Child Development and Family Life, October 25, 1968.)…

A nontechnical summary of the connection between malnutrition and intelligence, reports the findings of experimental research in animals and in human subjects. (MF)

Raccoons are a successful group of animals because they are able to defend themselves and they have characteristics which give them a remarkable ability to adjust or adapt. The raising of captured baby raccoons can cause survival problems for the animals. (CM)

Considers the potential value of two bodies of thought arising from work on animals in connection with rehabilitating abnormal behavior. One deals with the processes of catch-up and self-regulation, the other with optional periods of learning in development. (MP)

An interview with Duane Rumbaugh and Mary Ann Romski, researchers on the use of alternative communication systems for severely and profoundly retarded persons, focuses on applications from their primate research and the use of a computerized keyboard system to investigate language acquisition in severely retarded persons. (CL)

Reviews six books dealing with animals and ecology. (AEA)

Describes five new children's books about animals and other books about the development of anesthetics, the effects of bacteria, and the discovery of pheromones (scent chemicals that facilitate communication between members of an animal species). (GT)

The rhythmic patterning of man's biochemical, physiological, and psychological behavior and the temporal relationships among various functions are the province of chronobiology. Citing animal and human studies, the author documents the progress of this new science and poses complex questions that it may answer about human behavior. (Editor/SJL)

Studies the effects of playroom deprivation on self-motion play, or peragration, for rhesus monkeys of ages 24 to 36 weeks. (Author/SS)

The origin of the Big Dipper is described in this Canadian Indian legend. (RTS)

This delightful American Indian legend describes a meeting between a mountain lion, numerous domesticated cats, and a small boy. (RTS)

College biology students were asked to indicate whether they liked, disliked, or were neutral to each of 30 animals. Results indicate that Bart's conclusions (EJ 062 862), based on the assumption that students either like or dislike animals, may be unfounded. (BT)

Aims at providing data for evaluating the proposition that associations between exteroceptive (outside) stimuli and illness play a role in determining the effect of unconditioned stimulus preexposure on subsequent taste aversion conditioning. (Author/RK)
