Intricacies Of Development : The Impact Of Maternal Experience And Isolation On The Social Development Of Juvenile Male Rats, Lillian Maria Christon Aug 2007

Intricacies Of Development : The Impact Of Maternal Experience And Isolation On The Social Development Of Juvenile Male Rats, Lillian Maria Christon

Master's Theses

Reproductive experience induces changes in females. Parity-related differences in maternal treatment of offspring can induce enduring changes in offspring. The relationships between maternal experience, early social isolation, and development were explored in rodents in this experiment. Male rats were weaned from multiparous (MP) and primiparous (PP) mothers and placed into isolation or social housing for four weeks. They were then observed in a social-interaction test. Social behavior and neural oxytocin and vasopressin were assessed post-testing, while corticosterone levels were measured across the four weeks. Weaning was extremely stressful for all offspring. PP- and MP-raised pups exhibited differences in social behavior ...

Psychology, in a general sense, is age-old, extending back across all cultures to the beginnings of recorded time. The healing arts of ancient doctors and the conceptual musings of ancient sages often pointed toward factors that would be considered psychological today. Nevertheless, psychology in its specifically modern sense dates from the second half of the nineteenth century, when a self-consciously scientific, academic, professional discipline took shape in Europe and North America. This multiplex discipline grew and flourished in particular in the United States, where more than forty experimental laboratories, associated programs of research and study, and institutionalized means of communication ...


Modifications Of Nitric Oxide And Sexual Behavior In Prenatally Stressed Male Rats, Stephen D. Miller Aug 1999

Modifications Of Nitric Oxide And Sexual Behavior In Prenatally Stressed Male Rats, Stephen D. Miller

Master's Theses

Normal male sexual differentiation is the culmination of perfectly timed, prenatal gonadal hormone release. Prenatal stress (PS) has a detrimental effect upon this process, obstructing the natural development of brain structures and sexual behavior. Prenatally-stressed male rats exhibit many physiological and neuroendocrinological differences when compared to control males. PS has a particularly harmful effect upon male sexual behavior, to which the neurotransmitter nitric oxide (NO) has been shown to be intimately involved. The present experiment examined whether PS reduces nNOS, the rate limiting enzyme of NO, in the medial preoptic area (rnPOA) of male rats, and whether administration of the ...

Immanuel Kant And The Development Of Modern Psychology, David E. Leary Jan 1982

Immanuel Kant And The Development Of Modern Psychology, David E. Leary

Psychology Faculty Publications

Few thinkers in the history of Western civilization have had as broad and lasting an impact as Immanuel Kant (1724-1804). This "Sage of Konigsberg" spent his entire life within the confines of East Prussia, but his thoughts traveled freely across Europe and, in time, to America, where their effects are still apparent. An untold number of analyses and commentaries have established Kant as a preeminent epistemologist, philosopher of science, moral philosopher, aesthetician, and metaphysician. He is even recognized as a natural historian and cosmologist: the author of the so-called Kant-Laplace hypothesis regarding the origin of the universe. He is less ...
