This document provides an overview of how attitudes are formed and influenced when consumer effort is low. It discusses that low-effort processing is more likely to involve peripheral routes to persuasion using cues like music and visuals rather than central message arguments. It also outlines how unconscious influences, simple inferences, heuristics, affect, classical conditioning, source effects and message elements can shape low-effort cognitive and affective attitudes. Repetition, familiarity, mood, and dual mediation processes are also noted as influential on low-effort attitudes.
