Interactive and sequential aspects of information search
This study investigated the interactive and sequential aspects of information search as depicted in the Leigh and Johnston (1984) model. While the study focused primarily on the search process, the value of information and the roles of particular types of sources were also emphasized. Specific data used to examine the suggested relationships were derived from self-reported data regarding: (1) perceived costs, monetary and nonmonetary, for attaining information on particular attributes; (2) importance ratings of specific product attributes; (3) types of sources which could and probably would be contacted for additional information on those attributes; (4) the levels of correct and incorrect knowledge regarding specific product attributes; and (5) usefulness evaluations of particular source contacts. The data used to evaluate the hypothesized relationships were generated using a two-wave data collection process as recommended by Leigh and Johnston (1984). The initial instrument provided information from which to assess internal memory prior to active search. The second instrument enabled an evaluation of the dynamic nature of search, e.g., changes in importance ratings of certain attributes and relative benefits of attaining information regarding specific attributes. The study sample was developed from families whose children had attended computer science camps held at a state university in east Texas and that expressed an interest in purchasing a computer. Univariate, bivariate, and multivariate analyses provided general support for about one-third of the hypotheses specified for examination. Particular findings revealed that: (1) contact with particular types of sources enhanced the usefulness of specific information which was obtained from a different source; (2) the interactive role of memory mechanisms was determined to influence decisions to initiate, continue, and terminate search; (3) individuals employ several different heuristics during the process of search; (4) particular types of sources are perceived as being able to provide specific information about particular attributes; (5) search extensiveness and the amount of information received are positively related; and, (6) individuals obtained more useful information in the later stages of the search process...
