This study traces the development of Lincoln-Douglas debate in Texas. The history of this type of debate from the Great Debate between Abraham Lincoln and Stephen Douglas to the Reagan-Mondale debates is considered. In addition, the merits of this type of oral controversy are explored. The reasons for the creation of L-D debate and its introduction into the forensic curriculum are discussed. In order to measure L-D's growing acceptance in the debate community, the results of a questionnaire of Texas Forensic Association debate coaches is evaluated. This study found that L-D debate is growing in participation in Texas schools. The distinct features of L-D enable it to be an innovative and challenging form of discourse.

This study deals with the Supreme Court decision in the case of Miller v. California, 413 U.S. 15 (1973). The study analyzes the arguments presented in the decision by both the majority and the dissenting justices according to the Toulmin model. This study begins with a review of viewpoints on the First Amendment, and how they will be applied to the question addressed in the thesis. The history of the obscenity controversy is detailed to explain the viewpoints that the Supreme Court has taken dealing with this problem. This study concluded that the arguments presented by the majority were not supported by ample evidence. The arguments presented by Justice Douglas in the dissent were more justified. This study concludes that more study needs to be conducted in the area of obscenity; and that the material should not be suppressed.

This study surveyed the willingness of adolescents to self-disclose in different situations. One hundred and forty high school students were surveyed in a suburban, southwestern city. The survey included Gordon Chelune's Self-disclosure Situations Survey, Michael Leary's Social Anxiety Survey, and a 40-item situational survey created to test students' self-disclosure willingness in normal situations. It was hypothesized that students would more readily disclose to peers than parents or counselors; that they would more readily disclose in warm, informal settings than cold, formal ones; and that there would be a significant negative correlation between social anxiety and self-disclosure. There was a small but significant negative correlation between social anxiety and students' willingness to disclose only in a warm setting. The other hypotheses were proved.

Using the Aristotelian concept of artistic proof, this thesis analyzes nine televised speeches presented by President Reagan from February 1981 through April 1983. Reagan skillfully utilizes only two modes of rhetorical proof--ethos and pathos. However, his lack of logical proof has not lessened his effectiveness. This study reveals several reasons for Reagan's rhetorical effectiveness and success. For example, Reagan's strong ethical image and personality comfort his audience and encourage their trust. His weaknesses in logical argument are overlooked by his audience because of his high personal appeal. Furthermore, Reagan's use of pathos appeals makes Americans feel good about themselves and their country, helping him to maintain his popularity. Finally, Reagan's skillful use of the television medium has increased his effectiveness.
