The Effect Of Prenatal Administration Of Amphetamine Upon The Cognitive-Intellectual Functioning Of The Offspring At Adulthood, Theodore Cole
Masters Theses & Specialist Projects
The effect of prenatal administration of amphetamine upon the offspring’s cognitive-intellectual functioning at adult levels was investigated. Three groups of Max hooded rats were used, each composed of seven females and twelve males. One group was subjected to prenatal injections of amphetamine, one group received injections of saline, and the final group received no treatment. After the subjects reached adulthood they were presented with a series of complex mazes, and the dependent variable was the number of errors committed during the series. The data were analyzed by an analysis of variance of a 3 x 2 factorial design. The results …

The Effects Of A Sympathiomimetric Stressor On The Protestant Ethic Effect In Rats, Peter Mirabelle

In an experiment which investigated the effects of stress on the Protestant Ethic Effect (PEE) 12 Wistar rats were trained for 20 days to barpress for their total water intake. Following training the rats were divided into two groups and were allowed to choose between barpressing for a 10% sucrose solution and consuming a freely available sucrose solution under either stress or nonstress conditions. Stress was defined as a .01 cc per 36g body weight injection of norepinephrine. The stress and nonstress conditions were counterbalanced during the choice session. Regardless of stress order both groups preferred the free over the …

The Effects Of A Drug-Induced Stress On The Contrafreeloading Phenomenon In Rats, Jeanne Bennett
Masters Theses & Specialist Projects
The purpose of this experiment was to determine if stress, induced by intraperitoneal (IP) injections of epinephrine, influenced rats' preference to freeload (drink sucrose solution from a drinking tube) or to work for a liquid reinforcer (obtain sucrose solution by barpressing). Furthermore, the order in which stress was introduced was investigated.
Following two weeks of water deprivation, 6 female and 6 male Hooded rats approximately 90 days old were divided into two experimental groups. The first group (S-N) was stressed the first and second experimental testing days in which a choice was presented between barpressing and freeloading for a 10% …
