SPC4540 Persuasion is the study of how people are moved to change their minds — the theory of attitude change, and the strategies through which influence is actually exercised.
The course is offered at approximately five Florida institutions, including Florida Atlantic University, Florida State University, the University of Central Florida and the University of West Florida.
⚠ Two recognisably different courses run under this number, and the difference is the most important thing on this page. They are not different subjects — both are about persuasion — but they belong to two distinct scholarly traditions within communication, and they produce different graduates.
Florida State University titles it simply Persuasion and describes "a study of the psychology of attitude formation and change... theories of persuasion and principles of persuasive communication across multiple contexts." That is the social-scientific version: attitudes, cognition, measurement, experimental findings, and the theoretical models that explain when a message changes a mind.
The University of West Florida titles it Propaganda and Persuasion, places it in the Department of Communication at 3 semester hours, and describes a course that "explores persuasion theory of persuasive activity at a variety of turns in the modern world," with special focus on social movements, political campaigns and advertising, seeking "a clearer understanding of how persuasive strategy works, from where it emerges and why and how we are affected by it." That is the rhetorical and critical version: it studies persuasion as it appears in public life, analyses actual campaigns and movements, and asks about the social conditions that make particular appeals effective.
The distinction is real and worth understanding before you enrol. The social-scientific version asks what predicts attitude change, and answers with theories tested against data — the Elaboration Likelihood Model, cognitive dissonance, inoculation theory, the theory of planned behaviour. The rhetorical-critical version asks how this particular campaign worked and what it reveals, and answers by analysing texts, images and movements. Most well-taught sections include some of both, and the outcomes below are organised accordingly, but the centre of gravity differs and so does the assessment: expect theory application and research design in one, and critical analysis of real campaigns in the other.
What both share is the course's central and slightly uncomfortable insight: persuasion is a technique, and techniques are neutral about the ends they serve. The same mechanisms that make a public-health campaign effective make a disinformation campaign effective. A course that teaches you to construct persuasive messages necessarily teaches you to recognise them — and most instructors treat that dual character explicitly rather than pretending the subject is only about the honourable uses.
The propaganda material is where this becomes concrete. Studying twentieth-century state propaganda, wartime information campaigns, advertising history and contemporary disinformation is not a detour from persuasion theory; it is the same theory observed at scale and without ethical restraint. Students routinely report this as the most useful course in the communication major, and the reason is usually the same: it is difficult to be manipulated by a technique you can name.
This is one of the more directly vocational courses in a communication degree — the content maps onto identifiable job functions rather than onto general skills.
| Social-scientific (FSU) | Rhetorical / critical (UWF) | |
|---|---|---|
| Title | Persuasion | Propaganda and Persuasion |
| Central question | What predicts attitude change? | How did this campaign work, and why? |
| Method | Theory and experimental evidence | Critical analysis of texts and movements |
| Typical assessment | Theory application, research critique, exams | Campaign analysis essays, case studies |
| Reads like | Social psychology | Rhetoric and media criticism |
Both are legitimate, and neither is a watered-down version of the other. The tell is in the description and the assigned text: Perloff or O'Keefe signals the social-scientific version; Jowett and O'Donnell signals the propaganda-and-critical version. If you are heading toward graduate work in communication research, the social-scientific version is the better preparation; if you are heading toward campaign, agency or advocacy work, the critical version puts you closer to the material you will actually handle.
⚠ Statewide the title is "Persuasion", so UWF's "Propaganda and Persuasion" is the title drift, not the norm. The number is SPC4540 at all institutions, so the credit articulates regardless — but if a receiving programme has a specific expectation about which tradition the course belongs to, keep your syllabus.
UWF lists no prerequisite, which is common but slightly misleading given the course's 4000-level number.
⚠ "No prerequisite" is not the same as "no useful preparation." The genuinely useful background is a communication theory course (theories and vocabulary the course assumes) and, for the social-scientific version, an introductory statistics or research-methods course, because reading an empirical persuasion study critically means understanding what an experimental manipulation and a significance test actually establish. Public speaking (SPC1017 or SPC2608) is the other useful companion, since several assignments ask you to produce persuasive messages, not only analyse them.
The course normally sits in the junior or senior year of a communication, public relations or advertising major, and it is a frequent elective for political science, marketing, psychology and pre-law students. It is often a prerequisite or corequisite for a campaigns capstone.
3 credits, 45 contact hours — lecture and discussion, three hours per week, with a substantial share of class time given to analysing examples.
Expect 6–8 hours per week outside class. Assessment typically includes a campaign analysis project — the signature assignment in most sections — plus examinations, shorter analyses and often a produced persuasive message with a written strategic rationale.
⚠ The campaign analysis is where the grade is won or lost. The common failure is description: recounting what a campaign did without explaining, in the theory's terms, why it worked. Pick a campaign with accessible primary material — advertisements you can view, speeches you can read, coverage you can cite — and pick it early, because the research takes longer than students expect.
This course teaches techniques that work, and it teaches them to students who will use them professionally. Most instructors address that directly rather than leaving it implicit, and it is worth arriving expecting the conversation.
Two points are standard and both are defensible. First, the study of influence is also the best available defence against it — inoculation theory is literally about this, and media-literacy education is built on it. Second, professional practice has codes: the PRSA Code of Ethics, the AAF Principles, and the ethical frameworks the course teaches (the TARES test is the most commonly used) exist precisely because the techniques are powerful. A course that taught the techniques without the frameworks would be doing half a job, and the ethics material is not decorative.
SPC4540 is a 4000-level upper-division course, not offered at Florida College System institutions and not part of the A.A. general-education core.
The number is used consistently across the Florida institutions that carry it, so SCNS articulation is clean. The variation is in emphasis, not number.
⚠ Related numbers that are not this course. SPC3230 and SPC3231 are rhetorical criticism and rhetorical theory; SPC4680 is methods of rhetorical criticism (FSU) or rhetoric, media and civic life (UWF); SPC3210 is communication theory. None of these substitutes for persuasion, though several make good companions — and note that SPC4680 itself carries different titles at different institutions, which is a reminder to check descriptions rather than titles across the whole SPC prefix.
⚠ AI belongs in this course twice over — as a subject and as a tool — and the subject half is now the more important.
As a subject. Generative systems have changed persuasion in ways that bear directly on every theory in the syllabus:
As a tool for coursework. Language models are competent at brainstorming message variants, at drafting alternative appeals for comparison, and at summarising a theory. For a course that studies message construction, generating and then critiquing model-written appeals is a legitimate and revealing exercise — the outputs are fluent, conventional, and often illustrate exactly the heuristic-route persuasion the course is describing.
Where they fail. Models are poor at audience specificity — they produce generically persuasive prose rather than prose aimed at a defined segment, which is the actual skill. They fabricate campaign details, dates and statistics, which is disqualifying in an analysis assignment that depends on accurate primary material. And they flatten the ethical dimension, producing appeals that work without noticing that some of them should not be used.
Academic integrity. Read the syllabus. Policies vary, and in this course some instructors assign AI-generated persuasion as an object of analysis while prohibiting AI-drafted submissions — those two rules are consistent, not contradictory. Submitting generated work as your own violates every Florida institution's policy.
⚠ One professional note worth carrying beyond the course. In public relations, advertising and political communication, disclosure requirements around AI-generated content are being written now — by platforms, by professional associations, and increasingly by legislatures, Florida's included. A student entering these fields should expect the rules to be different by the time they are practising, and should follow the professional codes rather than the technical limits of the tools.
