A Comparison Of The Wechsler Adult Intelligence Scale-Revised With The Peabody Picture Vocabulary Test-Revised, Cynthia Burris

Masters Theses & Specialist Projects

The Peabody Picture Vocabulary Test (PPVT), a receptive vocabulary measure, and the Wechsler Adult Intelligence Scale (WAIS), a measure of general intelligence, have been two tests widely used by educators and psychologists, respectively. In addition to being used as a measure of receptive vocabulary, the PPVT was frequently used as a measure of intelligence. While the authors of the PPVT established IQ scores, this use of the PPVT frequently brought criticism from professional psychologists who felt that the test was not comprehensive enough to be used as a measure of general intelligence. The PPVT was revised in 1981, and the …

Environmental Psychology And Great Ape Reproduction, Terry L. Maple

Zoos and Aquariums Collection

At the 1980 Great Ape Infertility Workshop, we concluded that "physical and social environments must be improved if not optimized if great apes are to reproduce satisfactorily ... " In 1982, the trend toward improvement continues and there are some promising signs that reproduction has been enhanced as predicted. The problem of designing and evaluating captive environments which will facilitate interaction, reproduction, appropriate parenting, and socialization is well within the scope of Environmental Psychology. I intend to illustrate the promise of this applied research field in the remarks that follow.

Effects Of Moose, Alces Alces, On Aquatic Vegetation In Sibley Provincial Park, Ontario, D. Fraser, H. Hristienko

Feeding Behavior Collection

The effect of Moose (AIces aIces) on aquatic vegetation was studied in Sibley Provincial Park, Ontario. Two small exclosures were built in preferred feeding lakes to protect vegetation from Moose. Both exclosures developed a dense growth of plants. In one, species palatable to Moose were much more abundant than in unprotected areas. The other lake supported very little vegetation outside the exclosure. Aquatic vegetation in a large preferred lake underwent a series of changes from the 1960's to 1980. Nuphar variegatum and Potamogeton filiformis largely disappeared, leaving the lake sparsely vegetated in some years and dominated by annuals in others. …

The Effects Of Ethostasis On Farm Animal Behavior: A Theoretical Overview, A. F. Fraser, M. W. Fox

Ethology Collection

The solution of animal problems that occur on the farm requires a holistic and multidisciplinary orientation and analysis, as well as the acquisition of new investigatory tools by both veterinarians and animal scientists. Field studies may be modeled under more controlled laboratory conditions, but the most relevant investigations must take place on the farm, and the first level of analysis should be ethological. Domestic animal behavior can be monitored and quantified like any other factor in the animals' environment; yet it has been virtually ignored in the development of new livestock husbandry systems.

The relationships between husbandry systems, disease problems, …
