Signaling principle (multimedia learning)
Also known as: Cueing principle, Signaling effect
German: Signalisierungsprinzip
In the cognitive theory of multimedia learning, the signaling principle states that people learn better when cues highlight the organization of the essential material or the relations between words and pictures, for example headings, outlines, highlighting, arrows, color coding or matching labels.

In one sentence
The signaling principle: cues such as headings, highlighting, arrows and matching labels that show the essential material's organization aid learning.
Example
In an exploded view, the parts named in the text are numbered with the same numbers as in the step, and the part being removed is highlighted; readers find the part without searching the whole figure.
Rests on
- Selective attention and Salience (cognitive psychology): cues direct attention to what matters.
- Visual search and Gestalt principles of perceptual grouping: cues that group related elements reduce search.
How it applies
- Text: Informative headings, step numbers, lists, bold for interface elements, consistent typographic conventions.
- Figures: Callouts, arrows, highlighting of the relevant part, the same identifiers in text and figure (text–picture signaling).
- Video: Pointers and zoom on the part being discussed.
- Machinery and software documentation: Highlight the control or field the step refers to; use the same names as the HMI.
Signaling principle vs. signal words
Signaling cues show the structure of instructional material. Signal words in safety messages (DANGER, WARNING, CAUTION) indicate the severity of a hazard according to the conventions of the applicable standards, for example in a warning message. The two must not be mixed: using safety colors or signal words for emphasis in ordinary text weakens them.
Limits
- The meta-analyses found positive effects on average, with variation by type of cue, learner and outcome; too many cues lose their function.
- Evidence comes mainly from learning experiments.
