Used to think in terms of perception, cognition and emotion when designing instructional software. L’histoire se… now it’s (digital) content.
“A cognitive effect is just a change in the mind of the audience. When we learn or are influenced or make a decision, there is a corresponding cognitive effect. Most of these are small and incremental. Some are breakthroughs. All things considered, breakthroughs are more relevant than small changes to our attitudes. The actual theory is quite a bit more complex than this, but we can gloss over that complexity for the time being.”
(James Mathewson ~ Writing for digital)
