The Effects Of Prenatal Stress On The Size Of The Corpus Callosum, Richard K. Rowe Ii Aug 1994

The Effects Of Prenatal Stress On The Size Of The Corpus Callosum, Richard K. Rowe Ii

Master's Theses

The effects of prenatal stress on the size of the corpus callosum in rats was investigated using a prenatal heat, light, and restraint stress paradigm that influences the fetal hormonal milieu (Ward, 1972). Females were stressed thrice daily from Day 15 of pregnancy until parturition. Control females were left unstressed throughout their pregnancies. In adulthood (M = 223.16 days of age), male and female offspring from the two groups were sacrificed. Area, perimeter, and length of the corpus callosum were determined from sagittal sections of each brain. Results showed a sex difference for area, perimeter, and length of the corpus …


The Effects Of Positive And Negative Retrieval Cues On Release From Retroactive Interference, Michael P. Etgen May 1994

The Effects Of Positive And Negative Retrieval Cues On Release From Retroactive Interference, Michael P. Etgen

Master's Theses

The following study examined the effects of positive and negative retrieval cues within a release from retroactive interference design. Predictions based upon a modification to the cue-overloading hypothesis were evaluated. Subjects were 79 Introductory Psychology students. They learned two lists, each composed of four-legged animals, and were tested for recall of the originally-learned list. Informed subjects were supplied with a retrieval cue for the interpolated list to provide a release from retroactive interference. All subjects were further divided into those who were released by becoming aware during original learning and those who were not. Comparisons revealed a reliable and comparable …

The Anterior Commissure : The Effects Of Sex And Prenatal Stress, Hendree Evelyn Jones Apr 1994

The Anterior Commissure : The Effects Of Sex And Prenatal Stress, Hendree Evelyn Jones

Master's Theses

The effects of prenatal stress (light/restraint) on the development of the anterior commissure (AC) were investigated. The AC is known to be a sexually dimorphic structure of the brain not directly involved in reproductive behavior; unlike hypothalamic structures and nuclei, however, little is known about its development. The present work examines two factors, sex and stress, known to influence other brain areas. Pregnant rats were assigned to prenatal treatment and control groups. The treatment group was stressed thrice daily for thirty minutes using light/restraint during the third trimester (day 14-21). Control dams remained undisturbed. Male and female offspring were killed …
