Title: Predicting information searching performance with measures of cognitive diversity

Abstract: This study developed a framework for predicting information searching performance through an understanding of how cognitive traits relate to searching process and outcome. Specifically, this study examined the relationship of field-independence, spatial visualization, logical reasoning, and integrative reasoning to information searching process and outcome.

Information searching process was assessed by seven search process indicators: (1) search command selection; (2) combination of search commands; (3) application of Boolean logic; (4) application of truncation; (5) use of limit search function; (6) number of search statements; and (7) number of search errors made. Searching outcome was assessed by the number of correct answers to a set of test search questions.

Seventy undergraduate students, recruited from the University of Wisconsin-Madison campus during the 2000 Spring and Fall Semesters, received four standardized cognitive tests that measured cognitive style and abilities and then performed online catalog searches in response to seven information search questions. The searches were logged using Lotus ScreenCam for later analysis.

Each hypothesis was tested through zero-order correlation to determine the relationships between the independent variables and dependent variables. As a post hoc analysis, exploratory factor analysis was used to find underlying structures of the seven search process variables. Three process factors, the primary, the advanced, and the resultant process factors, were identified. Finally, multiple regression analysis was applied to examine the predictive power of four cognitive variables on three extracted factors and on search outcome.

Results of the data analysis showed that individual differences in field-independence and logical reasoning were associated with information searching process and outcome. Based upon Barren and Kenny (1986), this study then proposed a three-variable path, which is called mediational model. This model holds that field-independence and logical reasoning ability give rise to the primary process that, in turn, predicts search outcome.

The results of this study emphasize the importance of considering cognitive variables as important predictors to information search process and outcome; additionally, measures of the search process appear to play a mediating role between cognitive variables and search outcome.
