Providing cognitive support with technology-based warning systems.

New and emerging technologies promise to revolutionize risk communication. The benefits of technology are discussed with regard to the components of a recently described warning process model. Examples are provided to illustrate how technology can potentially improve information accessibility and cognitive support. Design principles such as warning interactivity, dynamic modification and personalization are considered as potential applications of technology that should enhance warning effectiveness in future technology-based systems.

A survey of World Wide Web use in middle-aged and older adults.

We conducted a survey to document World Wide Web use patterns in middle-aged (ages 40-59), young-old (ages 60-74), and old-old adults (ages 75-92). We conducted this survey of 550 adults 40 years old and over in southeastern Michigan, and the overall response rate was approximately 71%. The results suggested that (a) there are distinct age and demographic differences in individuals who use the Web; (b) middle-aged and older Web users are similar in their use patterns; (c) the two primary predictors for not using the Web are lack of access to a computer and lack of knowledge about the Web; (d) old-old adults have the least interest in using the Web compared with middle-aged and young-old adults; and (e) the primary content areas in learning how to use the Web are learning how to use electronic mail and accessing health information and information about traveling for pleasure. This research may serve as a preliminary attempt to ascertain the issues that must be faced in order to increase use of the World Wide Web in middle-aged and older adults.

Effect of age on event-based and time-based prospective memory.

The magnitude of age differences on event- and time-based prospective memory tasks was investigated in 2 experiments. Participants performed a working memory task and were also required to perform either an event- or time-based prospective action. Control participants performed either the working memory task only or the prospective memory task only. Results yielded age differences on both prospective tasks. The age effect was particularly marked on the time-based task. Performance of the event-based prospective task, however, had a higher cost to performance on the concurrent working memory task than the time-based task did, suggesting that event-based responding has a substantial attentional requirement. The older adults also made a significant number of time-monitoring errors when time monitoring was their sole task. This suggests that some time-based prospective memory deficits in older adults are due to a fundamental deficit in time monitoring rather than to prospective memory.
