Decision making
Large or difficult choice sets can reduce decision confidence or action when options are hard to compare and preferences are uncertain.
Interaction
In practiced choice-reaction tasks, response time tends to grow with the information uncertainty of the possible stimulus-response alternatives.
Mental models
A mental model is a person’s internal, partial representation of how a system works and what actions will produce.
Cognitive load
Progressive disclosure presents the information and controls needed now, then reveals additional detail when the user asks or the task reaches it.
Usability
Make relevant objects, actions, and options visible or readily retrievable so people do not have to recall them unaided.
Cognitive load
Some task complexity is irreducible, so design determines whether the system, the user, or an organization carries that work.
Mental models
A conceptual model is the designed explanation of a system’s objects, relationships, actions, and state that the interface presents to users.
Usability
Well-designed constraints limit invalid actions or make their boundaries clear while preserving valid choice and recovery.
Decision making
A preselected or no-action option is often chosen more frequently than an otherwise comparable alternative.
Decision making
Ownership or a sense of possession can increase the value assigned to an item relative to the value assigned before ownership.
Interaction
A mapping feels natural when the arrangement or movement of controls corresponds clearly to the arrangement or behavior of their effects.
Decision making
People may prefer an existing state or previously chosen option beyond what its attributes alone would predict.
