A dual‑process persuasion model that explains attitude change as occurring via two primary routes—central (high‑effort, message‑based processing) and peripheral (low‑effort, cue‑based processing)—with the route determined by recipients' motivation and ability to elaborate on message content.

Principle

Messages processed through the central route require cognitive elaboration of argument quality and therefore tend to produce attitudes that are more enduring and predictive of behaviour; peripheral processing relies on heuristics or cues and tends to produce more temporary or context‑sensitive attitude change.

Demonstration

Illustrative scenario → Situation: A library issues guidance about a new citation tool. Recognition: An engaged researcher reads detailed comparisons and evaluates evidence; a busy student notices only a faculty endorsement badge. Action: The researcher adopts the tool after assessing merits; the student follows the badge recommendation for convenience. Consequence: The researcher's attitude and continued use are more stable; the student's adoption may reverse under different situational cues.

Misapplication

Interpreting the model as a strict binary (central versus peripheral) and assuming any cue‑based acceptance is irrational; or assuming central processing is always preferable without regard to audience capacity or goals.

Consequence

Communicators should tailor message structure to audience motivation and ability: use substantive arguments for motivated, capable audiences and credible peripheral cues when elaboration is unlikely, understanding differences in durability and transferability of attitude change.

Reversal

When peripheral cues are diagnostic (e.g., a cue reliably correlates with message quality) or when situational constraints force cognitive shortcuts, peripheral processing can lead to appropriate, stable choices; conversely, overload or misinformation can undermine central processing outcomes.

Boundary

Clearly within: persuasive communication aimed at attitude change (e.g., information literacy campaigns). Boundary case: habitual behaviours influenced by non‑attitudinal cues that overlap with persuasiveness. Clearly outside: reflexive physiological responses or behaviours unrelated to deliberative attitude formation.

Semantic Tension

Persuasive effectiveness ↔ Ethical transparency — choosing peripheral cues may increase compliance but can conflict with norms about informed, deliberative decision making.

Synthesis

Effective persuasion in information settings matches argument quality and presentation to recipients' capacity and motivation: central processing yields more durable attitude change when feasible, but appropriate peripheral cues can facilitate uptake when elaboration is unlikely or unnecessary.
