Credibility Initial credibility is the expertise and trustworthiness listeners recognize before a presentation begins. Derived credibility is the expertise and trustworthiness that listeners recognize as a result of how speakers communicate during presentations. Terminal credibility is the cumulative expertise listeners recognize in a speaker based on initial and derived credibility.

Initial Credibility + or – Derived Credibility = Terminal Credibility

Building Credibility State your qualifications for speaking on this topic. Show listeners that you care about them. Appeal to listeners’ emotions. Reason carefully and avoid reasoning fallacies. Use effective and ethical supporting materials. Use verbal and nonverbal to show you are involved with the topic. Respond to questions with open-mindedness and fairness.

Speakers who want to be judged as credible should establish goodwill toward listeners. -McCroskey, J., &Treven, J. (1999) Show understanding of listeners’ ideas, feelings, and needs. Demonstrate empathy. Be responsive to listeners by being attentive and by reacting to listeners’ communication.

Organizing Speeches for Persuasive Impact Your introduction should capture listeners’ attention, provide a clear thesis statement, and preview what your speech will cover. Your conclusion should summarize main points and end with a strong closing statement. You should provide internal summaries. You should provide smooth transitions. The body of your speech should be organized to reinforce your thesis and show listeners how your ideas cohere.

Should You Present One or Two Sides? 1. Do listeners expect more than one side of the topic? What is/are the listeners’ educational level (s)? Has there been any pre-speech publicity? Do listeners care about hearing both sides? 2. What are listeners’ attitudes toward your topic? Do they have a position? Is it the same as yours? How strongly do listeners hold their opinions? 3. What level of knowledge do your listeners have? Do they know more than one side of the issues? How much information have they already gained? 4. Are listeners likely to encounter counterarguments after you speak? Inoculation immunizes listeners in advance against opposing ideas they may hear in the future.

Lloyd Bennett works for a public relations firm that wants to convince Casual Cruise Lines to become a client. Lloyd could use any of the eight basic organizational patterns to structure his speech to persuade the cruise line to hire his firm. On the following slides you can observe how his presentation would change depending on what outline pattern he selects.

Time Pattern Chronological Our firm can move Casual Cruise Lines into the future. I. Originally Casual Cruise Lines attracted customers whose average age was 58. II. In recent years, that customer base has shrunk. III. To thrive in the years ahead, Casual Cruise Lines needs to appeal to younger customers.

Spatial Pattern Left to right, top to bottom, north to south Our proposal focuses on redesigning the space on cruise ships to appeal to the 30-40 year old market. I. In the staterooms, we propose replacing the conventional seafaring motif with abstract, modernistic art. II. In the public area of the lower deck, we propose replacing the current coffee shops with sushi and expresso bars and adding fitness work out rooms. III. On the upper deck, we propose building hot tubs and Jacuzzis beside the pool.

Topical Categories or Classes Our firm has the most experienced advertising cruise lines and the most innovative staff. I. Our firm has increased revenues for three other cruise lines. II. Our firm has won more awards for innovation and creativity than the others Casual Cruise Lines is considering for this account.

Star Pattern Several main points work together to support a theme Star Pattern Several main points work together to support a theme. Different points are given more or less attention when speaking to different audiences. Let’s consider how younger customers might be attracted if we revamped ship décor, activities, and cuisine. I. Younger customers like modern décor. II. Younger customers want youthful activities. III. Younger customers want trendy foods.

Wave Pattern Each main idea builds up from evidence then crests in a main point The theme we propose is: No shuffle boards and no kids—Casual Cruise Line I. If you’re too young for shuffleboard, you’re ready for a Casual Cruise. II. If you’re too old to babysit, you’re ready for a Casual Cruise.

Problem-solution Describes a problem and then proposes a solution We have a solution to Casual Cruise Line’s inability to attract younger customers. I. Casual Cruise Lines hasn’t been able to get a substantial share of the lucrative 30-45 year old market. II. Our advertising campaign specifically targets this market.

Cause and Effect The advertising campaign we propose will attract young, affluent customers by appealing to their interests and life style. I. Our proposal’s emphasis on luxury features of the cruise caters to this market’s appreciation of extravagance. II. Our proposal to feature adults-only cruises caters to this market’s demonstrated preferences. III. Our proposal to offer 2-4 day cruises meets this market’s interest in long weekend get-aways.

Comparative Compares two or more objects, people, situations, events Our plan targets younger customers, not older ones. I. Shorter cruises for the busy lifestyle of 30-45 year olds. II. On board dancing and night clubs, which are favorite leisure activities of the 30-45 year olds. III. Adding 24-hour expresso bars and on-board fitness rooms speaks directly to the interests of 30-45 year olds.

The Motivated Sequence Pattern 1. Attention—focus listeners’ attention 2. Need—demonstrate a real problem exists 3. Satisfaction—propose a solution to solve the demonstrated problem 4. Visualization—give listeners a vision of the impact of the solution 5. Action—ask listeners to think, feel, or do something to bring the solution into being

Additional Persuasive Guidelines Build common ground with listeners. Work to find similarities between you and your listener (identification). Adapt to listeners. A good persuasive speech is crafted with specific listeners in mind. Audience analysis should assist you in understanding what your audience knows, believes and expects.

Fallacy An error in reasoning Presents false, or flawed logic Detracts from credibility because it suggests a speaker may not be ethical

Avoid Fallacies in Reasoning Ad hominem arguments go to the person not the idea. After this, therefore because of this mistakenly assumes because one thing follows another that the first caused the second. Bandwagon appeal argues that because most people believe or act a particular way, you should too. Reduction to absurdity involves pushing an idea to the point that it becomes ridiculous.

Avoid Fallacies in Reasoning Hasty generalization is a broad claim based on too few examples or too limited evidence. Red Herring arguments try to deflect listeners from relevant issues. Either-Or logic suggests that there are two and only two arguments. The Halo Effect occurs when we generalize an individual’s authority, or expertise, in a particular area to other areas that are irrelevant.
