This agriculture extension service publication from Pennsylvania State University discusses the control of vertebrate pests of urban and suburban ornamentals and turf. Specific pests described are blackbirds, chipmunks, moles, rabbits, and European starlings. Identification, habits, economic importance, and control methods ranging from poisoning…

Presented are two articles, an annotated bibliography, and other information useful in teaching about endangered species, especially those found in Florida. The articles provide an ethical rationale, teaching suggestions, and a discussion of the value of wildlife. Descriptions of over 100 pertinent books, periodicals, movies, and filmstrips are in…

The need for technicians and attendants in veterinary medicine was examined to determine the necessity of implementing training programs. Returns from 215 licensed veterinarians were obtained from the 692 surveyed. Some findings were: (1) The largest number of job vacancies were reported for animal technician graduates at the associate degree…

This training manual provides information needed to meet the minimum EPA standards for certification as a commercial applicator of pesticides in the industrial, institutional, structural and health related pest control category. The text discusses the use and safety of applying pesticides to control invertebrate and vertebrate pests such as ants,…

The purpose of this study is to determine categories of learning styles based on research on the chemical and physiological correlates of learning, as well as the development of simple measures that would allow an investigator to place a subject within one or more of these categories. The data from eight experiments with rats suggests that there…

A brief historical account of the use of animals in research is followed by descriptions of the use of animals in modern bio-medical experiments. Emphasis is given to studies investigating the effects of radiation on animals including both somatic and genetic effects. The effects of radiation in the environment are studied by analyzing animals for…

The results of this study suggested that size change may contribute to the forgetting of events occurring late in development, but that neurological immaturity may underly the forgetting of earlier events. (Editor/RK)

A general hypothesis of associative learning should be based on the broadest possible foundation of empirical evidence, including confirmation in both aversive and appetitive situations. For this reason the present experiment was designed to test the surprise hypothesis using a procedure in which the unconditioned stimulus was the presentation of…

Three experiments examined predictions generated by incorporating a common-elements account of stimulus generalization within the Rescoral-Wagner model of conditioning. (Editor)

Two experiments were conducted with rats to investigate variables responsible for the effectiveness of using a safe platform in two-way avoidance training and to evaluate the relative efficacy of several theoretical positions (conflict reduction, reinforcement, and freezing attenuation) that were offered to explain the wide differences in…

There has been considerable interest lately in cases where instrumental conditionability appears to depend on the reinforcer used. Here the effects of Pavlovian conditioned stimuli (CSs)on golden hamster behaviors was observed. The intent was to see whether previously reported differences among the behaviors produced by food reinforcement and…

Briefly discusses the views of Claude Levi-Strauss and Robert Ardrey who cite Rousseau as a personal influence even though they hold opposing anthropological ideals. The author claims that this situation is due to misinterpretations of Rousseau's work. An interpretation of Rousseau's anthropology is given reconciling the differences. (BC)

The learning of backward associations by pigeons during training of forward associations was studied in three experiments using a symbolic matching task. The data are contrasted with the strong evidence of learning of backward associations by humans. (Editor/RK)

Experimenters in the past have reported that when insulin is used as the unconditioned stimulus (US), rats will learn an aversion to a sodium chloride but not a sucrose solution, whereas with formalin as the US, they will learn an aversion to a sucrose but not a saline solution. The present experiments failed to confirm these findings. (Editor)

These experiments investigate the degree to which neophobia, the reluctance to consume novel food, can be modified by toxicosis, the conditions under which the contingency between ingestion and illness enhances neophobia, and the manner in which previously learned aversions mediate subsequent enhanced neophobia.
