Investigation Of Effects Of Hypnosis, Relaxation, And Mental Rehearsal On Performance Scores Of Golfers And Runners., Julie Nelson Jan 1980

Investigation Of Effects Of Hypnosis, Relaxation, And Mental Rehearsal On Performance Scores Of Golfers And Runners., Julie Nelson

LSU Historical Dissertations and Theses

The purpose of this study was to investigate the benefit of hypnotic techniques, relaxation, and mental rehearsal for improvement in performance scores for golfers and runners. Treatments were designed to be similar to interventions reported to be successful with individual athletes yet unsupported by larger investigations. No significant results were obtained for either sport. Explanations for obtained results included an actual absence of true effect, masking of effects by continuing methodological problems in the area of athletics and hypnosis, and the lack of generalizability of positive effect. Well controlled, indepth case studies were recommended for future investigation.

The Enzymology Of Methylation And Primary Structural Analysis Of Selected Phenylalanine Transfer-Rnas., James Joseph Schnabel Jan 1980

The Enzymology Of Methylation And Primary Structural Analysis Of Selected Phenylalanine Transfer-Rnas., James Joseph Schnabel

LSU Historical Dissertations and Theses

A tRNA (adenine-1)-methyltransferase from wheat germ was partially purified 9.6-fold and used to methylate tRNA('Phe) from E. coli. The site of methylation was determined to be the invariant adenine in the T(psi)C loop as revealed by sequence analysis of a pancreatic RNase digest, post-labelled with {(gamma)-('32)P}ATP. The elucidation of this site was preceded by studies on the enzyme itself, with bulk E. coli tRNA used as the substrate. Enzyme optima were determined for pH, temperature, {putrescine} and {magnesium}. Respective values were 7.5, 37(DEGREES)C, 20 mM, and an inactivation as the magnesium concentration was increased. Kinetic parameters at pH 7.5 were …

Speciation Of Environmental Pollutants By Gc-Aa And By Esca. Purification Of Water At Ultratrace Levels Of Heavy Metals And Complexation Studies By Electrochemical Methods., Ileana Aurea-Leon Rhodes

LSU Historical Dissertations and Theses

Speciation of environmental pollutants is essential for potential toxicity evaluations. It is important to determine what is the original chemical form of the pollutant when released in the environment as well as all possible reaction products and their potential hazards. The media through which these pollutants are transported in the environment are also of importance. Heavy metal pollutants usually occur in very low concentrations in the environment, therefore, very sensitive techniques are required for the determination of these metals. A GC-AA method was developed that allowed the simultaneous determination of PbEt(,4) and of PbEt(,3)Cl in gaseous and liquid samples. This …

Cognitive Processes In Depression., Sally Ann Davis Jan 1980

Cognitive Processes In Depression., Sally Ann Davis

LSU Historical Dissertations and Theses

Hypotheses derived from Beck's cognitive theory of depression were tested using 60 depressed and non-depressed males and females as measured by the Beck Depression Inventory. Subjects rated their performance before and after they received "positive," "negative," and "neutral" feedback regarding their performance on a social interaction task. They were also asked to recall feedback they received and explain reasons for their post-feedback self-rating. Results showed depressed males and females had a more negative evaluation of present circumstances and poorer memory for feedback. Further, depressed males lowered their self-evaluation upon feedback significantly more than did non-depressed males. In addition, depressed males …

Development And Applications Of Gas Chromatography - Atomic Absorption Interface Instrumentation., Eric Leon Kiesel

LSU Historical Dissertations and Theses

It is being recognized that we are exposed to increasing numbers of poorly understood and potentially toxic substances within our environment. To understand fully the human health effects and environmental impact of these hazards, complete chemical characterization or "speciation" studies of these hazards is necessary. Once exposure to a toxic substance has occurred, the physical and chemical form will determine the length of time a compound will remain in the environment and the types of chemical reactions that will occur in atmospheric, aquatic, and soil environments. Physiological and toxicological effects are also dependent upon the chemical form and physical form. …

Selective Antagonism Of The Rate‐Decreasing Effect Of D‐Amphetamine By Chlorpromazine In A Repeated‐Acquisition Task, Donald M. Thompson Jan 1980

Selective Antagonism Of The Rate‐Decreasing Effect Of D‐Amphetamine By Chlorpromazine In A Repeated‐Acquisition Task, Donald M. Thompson

Faculty Publications

Pigeons acquired a different four‐response chain each session by responding sequentially on three keys in the presence of four colors. The response chain was maintained by food presentation under a fixed‐ratio schedule. When d‐amphetamine was administered alone, the overall response rate decreased and the percent errors increased with increasing doses. When a small dose of chlorpromazine, which was ineffective when given alone, was administered in combination with d‐amphetamine, the rate‐decreasing effect was antagonized. The antagonism was selective, however, in that the error‐increasing effect of d‐amprotamine was augmented by chlorpromazine. The nature of the joint effect of the two drugs thus …

Effects Of D‐Amphetamine And Cocaine On Strained Ratio Behavior In A Repeated‐Acquisition Task, Donald M. Thompson, Joseph M. Moerschbaecher Jan 1980

Effects Of D‐Amphetamine And Cocaine On Strained Ratio Behavior In A Repeated‐Acquisition Task, Donald M. Thompson, Joseph M. Moerschbaecher

Faculty Publications

Pigeons acquired a different four‐response chain each session by responding sequentially on three keys in the presence of four colors. When the fixed‐ratio requirement for food presentation was five completions of the chain, d‐amphetamine and cocaine disrupted the behavior. As the dose of each drug was increased, the overall response rate decreased, the overall accuracy was impaired (i.e., percent errors increased), and there was less within‐session error reduction (acquisition). In contrast, when the fixed‐ratio requirement was either 20 or 50 completions of the chain, certain doses of both drugs produced large increases in the overall response rate by eliminating the …

Effects Of D‐Amphetamine, Cocaine, And Phencyclidine On The Acquisition Of Response Sequences With And Without Stimulus Fading, Joseph M. Moerschbaecher, Donald M. Thompson Jan 1980

Effects Of D‐Amphetamine, Cocaine, And Phencyclidine On The Acquisition Of Response Sequences With And Without Stimulus Fading, Joseph M. Moerschbaecher, Donald M. Thompson

Faculty Publications

In each of three components of a multiple schedule, monkeys were required to emit a different sequence of four responses in a predetermined order on four levers. Sequence completions produced food on a fixed‐ratio schedule. Errors produced a brief timeout. One component of the multiple schedule was a repeated‐acquisition task where the four‐response sequence changed each session (learning). The second component of the multiple schedule was also a repeated‐acquisition task, but acquisition was supported through the use of a stimulus‐fading procedure (faded learning). In a third component of the multiple schedule, the sequence of responses remained the same from session …
