Analyzing Communication Techniques

A strong critique does not simply list techniques; it evaluates whether each technique serves its purpose for its intended audience. When you analyze a communication sample, ask three linked questions: What technique is being used? What effect does it produce? Does that effect align with the speaker's or writer's apparent purpose? Separating technique from effect keeps your analysis precise rather than descriptive, which matters when exam responses are scored on depth of reasoning rather than mere identification.

Rhetorical appeals remain central to this framework. Ethos establishes credibility through tone, sourcing, or presenter demeanor; pathos builds emotional resonance through imagery, pacing, or word choice; logos structures an argument through evidence and logical sequence. The same appeal can be constructed very differently depending on medium: ethos in an oral presentation might rely on confident posture and vocal steadiness, while ethos in a print advertisement might rely on typography, credentials listed in small print, or an authoritative brand image.

Effective comparison requires noticing what each medium can and cannot do. Oral and video presentations allow real-time vocal and physical cues, so pacing, tone shifts, and strategic pauses carry much of the persuasive weight. Print texts cannot use vocal delivery at all; instead, they lean on layout, font size, white space, and imagery to direct attention and control emphasis. Digital media often blends both, adding editing choices such as cuts, captions, and background music that compress a persuasive arc into a short runtime.

Notice how the same underlying goal, building trust with an audience, takes different forms depending on the constraints and affordances of the medium. This is precisely the kind of cross-format reasoning that connects to Evaluating Persuasive Presentation Methods, where you examine persuasive intent more closely within a single format before comparing across several.

Exam-style tasks typically present two or more short excerpts, transcripts, or media descriptions and ask you to compare their communication strategies within a limited response. A reliable approach is to organize your answer around shared criteria rather than describing each source separately from start to finish. Choose two or three techniques that appear meaningfully in both sources (for example, use of emotional appeal and use of structural pacing), then discuss how each source handles that technique and with what relative effectiveness.

Support every judgment with a specific, quoted or closely paraphrased detail rather than a general impression. A response that claims a speech "uses pathos effectively" earns little credit; a response that identifies a specific pause before a key statistic, and explains how that pause heightens the statistic's emotional weight for the audience, demonstrates the close analytical reasoning that scoring criteria reward.

Comparative Analysis: An evaluative method that examines two or more communication samples against shared criteria to judge their relative effectiveness.

Rhetorical Appeals: Persuasive techniques, ethos, pathos, and logos, used to build credibility, emotional connection, or logical argument.

Medium Constraint: A limitation or affordance specific to a communication format, such as the absence of vocal cues in print or the compression of time in video.

Technique Versus Effect: The distinction between what a speaker or writer does and the impact that choice has on the audience's understanding or attitude.

Contextual Adaptation: The way a communicator adjusts strategy to suit a specific audience, purpose, occasion, or medium.

Practice by selecting two short samples on the same topic delivered through different media, for example a news broadcast segment and a related print editorial, and draft a paragraph comparing one shared technique across both. Time yourself producing this comparison in ten minutes to simulate exam pacing, then review your response for whether every claim is backed by a specific, cited detail rather than a general statement.
