1. Capture Error
> Error of automatically (learned behavior).
> Example: Well-used interactive sequence SAVE..QUIT executed inappropriately
2. Description Error
> Execution of a correct action directed toward the
wrong object
> Example: clicking the maximize button instead of the close button
3. Data-driven Error
> Unconscious data processing interference
> Example: saving a file with the title of an unrelated document
4. Associative-activation Error
> Like data-driven error, but an internal, semantic
mismatch occurs instead
> Example: naming a file with the name of its intended recipient
rather than it’s subject title.
5. Loss-of-activation Error
> Working memory failure
> Midway through an augmentative task used to achieve a goal, you
forget what the goal was.
> Example: an Internet search
6. Mode Error
> User perceives the system to be in a state that
it is not
> Example: Drawing in Microsoft’s Word; Mode is select rather
than draw
