A study was conducted to examine the effects of altering aspects of two of these task categories on problem solving behavior across skill levels: materials and goals. Two versions of an applied engineering problem were presented to expert, intermediate, and novice participants. Participants were to minimize the cost of running a steam generation facility by adjusting steam generation levels and flows. One version was cast in the form of a dynamic, computer-based simulation that provided immediate feedback on flows, costs, and constraint violations, thus incorporating key variable dynamics of the problem context. The other version was cast as a static computer-based model, with no dynamic components, cost feedback, or constraint checking. Experts performed better than the other groups across material conditions, and, when required, the presentation of the goal assisted the experts more than the other groups. The static group generated richer protocols than the dynamic group, but the dynamic group solved the problem in significantly less time. Little effect of feedback was found for intermediates, and none for novices. We conclude that demonstrating differences in performance in this task requires different materials than explicating underlying knowledge that leads to performance. We also conclude that substantial knowledge is required to exploit the information yielded by the dynamic form of the task or the explicit solution goal. This simple model can help to identify the contextual factors that influence elicitation and specification of knowledge, which is essential in the engineering of joint cognitive systems.<\/jats:p>","DOI":"10.1518\/001872000779656589","type":"journal-article","created":{"date-parts":[[2007,1,25]],"date-time":"2007-01-25T18:02:02Z","timestamp":1169748122000},"page":"56-74","source":"Crossref","is-referenced-by-count":11,"title":["Factors Influencing Analysis of Complex Cognitive Tasks: A Framework and Example from Industrial Process Control"],"prefix":"10.1177","volume":"42","author":[{"given":"Michael J.","family":"Prietula","sequence":"first","affiliation":[{"name":"University of Florida, Gainesville, Florida"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul J.","family":"Feltovich","sequence":"additional","affiliation":[{"name":"Southern Illinois University-Carbondale, Carbondale, Illinois"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frank","family":"Marchak","sequence":"additional","affiliation":[{"name":"Veridical Research and Design, Bozeman, Montana."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2000,3,1]]},"reference":[{"key":"atypb1","first-page":"24","volume":"81","author":"Ahearne, J.","year":"1993","journal-title":"American Scientist"},{"key":"atypb2","volume-title":"The architecture of cognition.","author":"Anderson, J.","year":"1983"},{"key":"atypb3","volume-title":"Cognitive psychology and its implications","author":"Anderson, J.","year":"1985","edition":"2"},{"key":"atypb4","volume-title":"Human memory: Theory and practice.","author":"Baddeley, A.","year":"1990"},{"key":"atypb5","first-page":"495","volume":"33","author":"Baron, A.","year":"1983","journal-title":"Psychological Record"},{"issue":"4","key":"atypb6","volume":"17","author":"Borron, J.","year":"1996","journal-title":"AI Magazine"},{"key":"atypb7","volume-title":"Artificial intelligence and learning strategies","author":"Brown, J.","year":"1977"},{"key":"atypb8","first-page":"149","volume-title":"The handbook of artificial intelligence","author":"Buchanan, B.","year":"1989"},{"key":"atypb9","first-page":"8","author":"Campbell, C.","year":"1998","journal-title":"Scientific American"},{"key":"atypb10","first-page":"259","volume-title":"Mind matters: A tribute to Allen Newell","author":"Card, S.","year":"1996"},{"key":"atypb11","volume-title":"The psychology of human-computer interaction.","author":"Card, S.","year":"1983"},{"key":"atypb12","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1016\/B978-0-444-70536-5.50007-5","volume-title":"Handbook of human-computer interaction","author":"Carroll, J.","year":"1988"},{"key":"atypb13","first-page":"39","volume-title":"Toward a general theory of expertise: Prospects and limits","author":"Charness, N.","year":"1991"},{"key":"atypb14","first-page":"201","volume-title":"Proceedings of the 16th Annual Conference of the Cognitive Science Society","author":"Clement, J.","year":"1994"},{"key":"atypb15","unstructured":"deKleer, J.
