Improve motivation by emphasizing the importance of the task being performed.
Reduce the rate at which stimuli (which may or may not be signals) are presented.
Maintain noise, temperature, illumination, and other environmental factors at optimal levels.
Designing Information Processing Task for Elderly
Strengthen amplitude displayed signals.
Design controls/displays to reduce irrelevant details.
Maintain a high level of conceptual, spatial,
Reduce time-sharing demands.
Provide time between the execution of a response and the signal for the next response.
Allow more time and practice to learn the material.
