Interacting with technology is cognitive and involves many processes including attention, memory, perception, learning and recognition. The way an interface is designed can greatly affect how well users can perceive, attend, learn and remember how to undertake their tasks. The conceptual framework of mental models and external cognition provide ways of understanding how and why people interact with products, which can lead to thinking about how to design better products.

Extraits

[...] A study item must be presented on every question, along with 4 distractor items for both the controlled and the variable interfaces.

[...] A memory may no longer be available as it has not been accessed over time and accessibility reduces overtime through decay Jenkins and Dallenhach Decay Interval Experiment Jenkins and Dallenhach (1924) proved that what happens in-between learning and recall, determines forgetting in the short-term memory, not the length of time between rehearsal and recall. The pair set out to test if decay is a natural result of the passage of time, by making two groups learn a 10-item list of nonsense syllables, either late at night, or early in the morning. The ‘night’ group were woken after one, two, four, or eight hours and tested for recall. [...]

[...] Cognition is involved in everything a human might possibly do. Jennings (2003) stated that interacting with technology is cognitive. Cognition involves many processes including attention, memory, perception, learning and recognition. The way an interface is designed can greatly affect how well users can perceive, attend, learn and remember how to do their tasks. The conceptual framework of ‘mental models’ and ‘external cognition’ provide ways of understanding how and why people interact with products, which can lead to thinking about how to design better products.
