INFORMATION TO USERS
This material was produced from a microfilm copy of the original document. While
the most advanced technological means to photograph and reproduce this document
have been used, the quality is heavily dependent upon the quality of the original
submitted.
The following explanation of techniques is provided to help you understand
markings or patterns which may appear on this reproduction.
1. The sign or "target" for pages apparently lacking from the document
photographed is "Missing Page(s}". If it was possible to obtain the missing
page(s) or section, they are spliced into the film along with adjacent pages.
This may have necessitated cutting thru an image and duplicating adjacent
pages to insure you complete continuity.
2. When an image on the film is obliterated with a large round black mark, it
is an indication that the photographer suspected that the copy may have
moved during exposure and thus cause a blurred image. You will find a
good image of the page in the adjacent frame.
3. When a map, drawing or chart, etc., was part of the material being
photographed the photographer followed a definite method in
"sectioning" the material. It is customary to begin photoing at the upper
left hand corner of a large sheet and to continue photoing from left to
right in equal sections with a small overlap. If necessary, sectioning is
continued again — beginning below the first row and continuing on until
complete.
4. The majority of users indicate that the textual content is of greatest value,
however, a somewhat higher quality reproduction could be made from
"photographs" if essential to the understanding of the dissertation. Silver
prints of "photographs" may be ordered at additional charge by writing
the Order Department, giving the catalog number, title, author and
specific pages you wish reproduced.
5. PLEASE NOTE: Some pages may have indistinct print. Filmed as
received.

ACKNOWLEDGEMENT
Too many people to name have been of great help to me during
my years of graduate work at L. S.U. Several people, however, de
serve special recognition. I would like to thank Dr. Fred Endsley,
who has been my friend, counselor, and teacher since my under
graduate days, and Dr. Alvin Burns, who has spent a great deal of
time on my behalf during the short time I have known him. Their help
and guidance have been invaluable to me. My thanks also go to my
aunt, M rs. Max Schenker, for all of the things she has done for me,
not the least of which was providing me a home during the first year
of my doctoral work. Finally, I would like to thank my parents. With
out them this dissertation would never have been written. Their
support, both m oral and financial, made this undertaking possible.

Description:second experim ent was conducted to determ ine how effective a re fu ta tio n al-d iffe ren t defense was in com parison to a refu tatio n al-sam e defense. The experim ent, in which only passive defenses w ere used, showed that both refu tation al defenses resulted in increased resistance to persu
