Searching for information on the web: Impact of cognitive aging, prior domain knowledge and complexity of the search problems
作者：
Highlights：
• Prior domain knowledge improves older adults’ query and navigation strategies and copes with the age-related decline of cognitive flexibility.
• Unlike prior results, older adults were outperformed by young ones in open-ended information problems.
• In open-ended information problems, older adults did not benefit from their prior knowledge and produced semantically less relevant queries as compared to fact-finding problems.
