Logical Reasoning and Retrieval Performance.
Peer reviewed Peer reviewed
Allen, Bryce – Library and Information Science Research, 1993
A study of logical reasoning ability of endusers searching a CD-ROM index and its correlation to searching performance was conducted at the University of Illinois at Urbana-Champaign. Findings showed a correlation between cognitive skills and citation selection and indicated that computer system design can be improved using a cognitive engineering…
