Applied cognitive psychology
Also known as: Applied cognition
German: angewandte Kognitionspsychologie
Applied cognitive psychology is the branch of psychology that uses research on perception, attention, memory, comprehension, judgment and action to understand and improve how people perform real tasks with real products, tools and information, outside the laboratory conditions in which the underlying theories were developed.

In one sentence
Applied cognitive psychology uses research on perception, memory, comprehension and action to improve how people use real products and information.
Example
A documentation team learns from working memory research that operators lose track of long procedures; it applies this by limiting steps per task, numbering them and adding a check step before the machine is restarted, and then tests the result with operators.
Rests on
Every entry in this glossary rests on at least one theory entry of the glossary cognitive psychology for technical communication: for example Working memory, Selective attention, Cognitive load theory, Human information processing or Situation model. The theory describes how people take in and use information; the application says what documentation does with it.
How it applies
- The split used on this site: The theory glossary is descriptive: what research shows, with an evidence status and named myths. This glossary is prescriptive: design principles (for example plain language or the spatial contiguity principle), practices (job aids, checklists, worked examples) and evaluation methods (usability testing, think-aloud protocols, card sorting, symbol comprehension tests). Each entry names the theory it rests on and its limits.
- Machinery documentation: Applied findings shape how procedures are chunked and numbered, where safety messages are placed relative to the step they concern, and how figures and text are combined in instructions for use.
- Software documentation: They inform navigation and search, link wording, examples and the layering of quick starts and reference.
- Evaluation: Applied cognitive psychology prefers testing with representative users over judging a text by rules alone; see usability and safety information usability.
Applied vs. basic cognitive psychology
Basic research isolates a mechanism under controlled conditions, often with students and short artificial materials. Applied research asks whether and how the effect holds for real users, tasks and environments, and adds constraints such as time pressure, noise, gloves or interruptions. A principle that works in the laboratory has to be checked again in the context of use.
Limits
- Findings transfer only as far as the populations, tasks and materials resemble those studied; many multimedia and learning findings come from students learning from short lessons.
- No cognitive principle makes documentation compliant or a product safe. It never replaces the risk assessment or the information the applicable law requires, and it never justifies omitting or hiding safety-related information.
