The document provides a concept for a diploma thesis in marketing that will examine the impact of source identification on the evaluation of consumer-generated advertising. The thesis will test hypotheses about how source credibility and perceived similarity affect attitudes toward ads and brands. It outlines the introduction, literature review on key topics like user-generated content and the source effect, proposed research questions and hypotheses, and planned research methodology using a 2x2 between-subjects design.

18. BRANDS ARE A COMPLEX
SYMBOL. IT IS THE
INTANGIBLE SUM OF A
PRODUCT'S ATTRIBUTES,
ITS NAME, PACKAGING
AND PRICE, ITS HISTORY,
REPUTATION, AND THE
WAY IT'S ADVERTISED.
19. A BRAND IS ALSO DEFINED
BY CONSUMER'S
IMPRESSION OF PEOPLE
WHO USE IT, AS WELL AS
THEIR OWN EXPERIENCE.

57. COGNITIVE RESPONSE THEORY
INSIGHTS
"IN RESPONSE TO A PERSUASIVE APPEAL, INDIVIDUALS REHEARSE
THEIR ISSUE-RELEVANT THOUGHTS, AS WELL AS THOSE PRESENTED TO
THEM."
THE MORE CREDIBLE THE SOURCE, THE MORE THE REHEARSAL OF
THEIR [THE INDIVIDUALS'] OWN REPERTOIRE OF ATTITUDE RELEVANT
THOUGHTS GETS SUPPRESSED BY THE APPEAL.

58. COGNITIVE RESPONSE THEORY
INSIGHTS
"DEPENDING ON THE INDIVIDUALS' INITIAL PREDISPOSITION TOWARDS
THE ADVOCACY - IN FAVOR VS AGAINST - THE PERSUASIVE EFFECT OF
THE APPEAL CAN BE MODERATED BY THE LEVEL OF SOURCE
CREDIBILITY."
Source: Sternthal et al. 1978a, 1978b
60. THE
THEORY
AN APPEAL PRESENTED BY A MODERATELY CREDIBLE SOURCE TO AN
INDIVIDUAL WITH A POSITIVE INITIAL ATTITUDE TOWARDS THE ISSUE,
MIGHT BE MORE EFFECTIVE THAN THE SAME APPEAL PRESENTED BY A
HIGHLY CREDIBLE SOURCE.
THIS THEORY WAS REPLICATED IN TWO EXPERIMENTAL STUDIES, IT'S RELEVANCE HAS NEVER BEEN INVESTIGATED IN AN ADVERTISING CONTEXT.
Source: Sternthal et al. 1978a; 1978b
62. RESEARCH
QUESTIONS
A) DOES THE EXISTENCE OF SOURCE CREDIBILITY EFFECTS IN CGAs, DEPEND ON THE
INITAL PREDISPOSITION OF THE SPECTATOR TOWARD THE ADVERTISED BRAND?
B) DO CGAs BENEFIT FROM AN INCREASED LEVEL OF PERCEIVED SIMILARITY
BETWEEN THE SPECTATOR AND THE SOURCE?
C) WHICH IMPACT DOES THE LEVEL OF ISSUE INVOLVEMENT HAVE ON THE
EVALUATION OF CGAs?
