INTRODUCTION

English translation pending.

CORE DEFINITION

A multimedia learning principle holding that visual and auditory information should be consistent and complementary rather than contradictory or redundantly duplicated. The core proposition is that the two channels are processed in partly separate systems, so alignment adds capacity while conflict forces the learner to resolve a mismatch, consuming the resources comprehension requires. The key qualification is that congruence means agreement in meaning and tone, not duplication of the same content, since restating identical words in both channels overloads rather than reinforces. This entry consolidates the several variant names for the same alignment principle.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Tone alignment: match the emotional register of the imagery to the register of the narration. - Conflict scan: list every place where the two channels carry different or opposed messages. - Reception test: check with viewers whether the two channels were read as one message.

Anchor fast decisions

Visual and auditory input enter partly separate processing systems, so information split across them can be handled in parallel and total capacity rises. When the two channels disagree, the systems produce incompatible representations and the learner must spend effort deciding which to trust, which reduces the capacity available for understanding and leaves an unresolved sense of dissonance. Congruence removes that arbitration cost, so the same presentation carries more usable meaning.
