Cognitive load occurs when the demands of a task surpass the available processing capacity, straining mental resources and potentially impairing performance efficiency, such as increasing the number of errors in a task. Owing to its ubiquity in real-world scenarios, the existence of offloading strategies to reduce cognitive load is not new to…

This report, the product of a collaboration between the Organisation for Economic Co-operation and Development (OECD) and the UK-based charity, Education and Employers, offers a glimpse of how children see their future, and the forces that, if properly understood and harnessed, will drive them forward to realise their dreams. Through concerted…

Discussion of user problems with navigating large spaces in virtual information environments focuses on a top-down application of semantic knowledge by the user from experiences within the sociocognitive context of information production and consumption. Considers individual differences in studies of interaction; spatial and semantic cues; and…

Describes four major types of learning theories (behavioral, cognitive, cybernetic, and andragogical); examines pertinent literature for each; and traces links between the literature of learning theory and that of the design of online public access catalog instructional systems. (32 references) (Author/CLB)

Discusses individual differences between users of information systems that can influence search performance, and describes two experiments that addressed user-centered design of information systems. Highlights include interaction between cognitive abilities and design features; compensation and capitalization perspectives; recall and precision;…

Presents two empirical case studies concerning the role of individual differences in searching through a spatial-semantic virtual environment. Discusses information visualization in information systems; cognitive factors, including associative memory, spatial ability, and visual memory; user satisfaction; and cognitive abilities and search…

Online searching is a complex problem solving task requiring the searcher to combine multiple sets into Boolean expressions. Since spatial ability has been correlated with problem solving tasks which involve abstract conceptual associations, this report argues that it is a significant factor in the information user's ability to both comprehend and…
