The Effects Of Forebrain Ablations On Some Behaviors In Xenopus Laevis, Lawrence Paul Kunstadt

Dissertations, Theses, and Capstone Projects

In order to further elucidate the hypothesis that the telencephalon of ectothermic vertebrates functions primarily as a non-specific arousal mechanism, facilitating lower brain areas, (the Arousal Hypothesis) the South African clawed frog, Xenoous laevis, was studied in four behavioral situations before and after telencephalon ablation, olfactory bulb ablation or sham surgery. Particular attention was paid to measurements of the temporal aspects of the behaviors studied.

The behaviors studied were:

1. Habituation to an acoustic-vibratory stimulus

2. The optomotor response

3. Escape from shallow water

4. Feeding behavior

In the habituation experiment no changes were found in the number of …

Montemayor's "Diana": A Translation And Introduction, Roseanna M. Mueller

Dissertations, Theses, and Capstone Projects

Jorge de Montemayor's Los siete libros de la Diana (1559) was one of the more popular Renaissance pastoral romances. This Spanish pastoral romance written by a Castilianized Portuguese had many continuations. It influenced other pastoral works in England, and enjoyed a wide readership throughout Europe, as its many editions and translations witness. The Diana is a transitional work and an example of what writers of prose fiction were striving for in the middle of the 16th century. The Diana retained elements of the chivalric romance, integrated Petrarchan influences that had hitherto been reserved for the lyric, adhered to Neoplatonic love …

Effects Of Instructions And Stimulus Representation On Selective Learning In Children, Adele E. Gottfried

Dissertations, Theses, and Capstone Projects

Selective learning patterns of children were investigated using incidental learning methodology. Since incidental, in contrast to intentional learning occurs in the absence of instructions which prepare the subject for later retention tests, a subject has relatively more freedom to choose to attend to and learn only a portion of the presented information (thus exercising selectivity). Previous research suggested that selectivity seemed to increase or decrease with development in relation to different incidental learning paradigms. For studies in which incidental stimuli were presented without a concurrent intentional task (Type 1) incidental learning increased with age indicating decreased selectivity. For studies in …

Non-Metric Scaling Of Loudness, Alan M. Richards

Dissertations, Theses, and Capstone Projects

Determination of loudness scales for 1000 Hz stimuli by conventional ratio scaling methods have yielded loudness functions which grow as approximately the 0.54 power of sound pressure. Thus, two-fold loudness differences are equivalent to approximately 10 dB across the auditory continuum. The unidimensional representation of loudness ss a power function of sound intensity implies that if A is twice as loud as B, which, in turn, is twice as loud C, the A will be four times as loud as C. In order to test this implication across the auditory continuum loudness ratio estimates were obtained from four 7x7 matrices …
