“…Byrne, John, Wehrle, & Crow, 1999). Scholars have denoted these as cognitive search models (Navarro-Prieto et al, 1999;Thatcher, 2006Thatcher, , 2008, decision making in search (Browne et al, 2007), and information foraging (e.g., Pirolli, 2007).Although the effectiveness of online searching relative to other sources has also been examined (e.g. Hodkinson & Kiel, 2003;Sohn, Joun, & Chang, 2002), cognitive search models focus only on online behavior.…”

“…However, although online shopping is proceeded by information search, it seeks to obtain resources and is influenced by a user's own previous experience with a physical product or brand (Rowley, 2000). Hence, this is distinct to Rose and Levinson's (2004) directed information goals that would apply to the professional medical context.For this reason, our study focuses on general Internet search literature, where action models (Thatcher, 2006(Thatcher, , 2008 represent a major stream detailing users' specific "moves" in search (Marchionini & Schneiderman, 1988). Scholars identify two fundamental starting choices: accessing a general search engine or using a familiar Web site (Choo, Detlor, & Turnbull, 2000;Holscher & Strube, 2000).…”

Literature examining information judgments and Internet search behaviors notes a number of major research gaps, including how users actually make these judgments outside of experiments or researcher-defined tasks, and how search behavior is impacted by a user's judgment of online information. Using the medical setting, where doctors face real consequences in applying the information found, we examine how information judgments employed by doctors to mitigate risk impact their cognitive search. Diaries encompassing 444 real clinical information search incidents, combined with semistructured interviews across 35 doctors, were analyzed via thematic analysis. Results show that doctors, though aware of the need for information quality and cognitive authority, rarely make evaluative judgments. This is explained by navigational bias in information searches and via predictive judgments that favor known sites where doctors perceive levels of information quality and cognitive authority. Doctors' mental models of the Internet sites and Web experience relevant to the task type enable these predictive judgments. These results suggest a model connecting online cognitive search and information judgment literatures. Moreover, this implies a need to understand cognitive search through longitudinalor learning-based views for repeated search tasks, and Received June 13, 2009; revised August 12, 2009; accepted September 3, 2009 Additional Supporting Information may be found in the online version of this article. IntroductionInformation search is a process by which a person seeks knowledge about a problem or situation, constituting a major activity by the Internet's millions of users (Browne, Pitts, & Wetherbe, 2007). The Web is now a primary source of information for many people, driving a critical need to understand how users search or employ search engines (Jansen & Spink, 2006). Extensive literature examines not only behavioral models detailing the different moves or tactics during Internet search but also decision making or strategies described as cognitive search models (Navarro-Prieto, Scaife, & Rogers, 1999;Thatcher, 2006Thatcher, , 2008. The latter examines the cognitive aspects of the moves users employ to optimize their search performance, exploring elements such as expertnovice differences or judgments on when to terminate the search (e.g., Thatcher, 2006Thatcher, , 2008Cothey, 2002;Jaillet, 2003;Browne et al., 2007). This notion of judgment introduces a second stream of literature, Internet information judgments, where authors note that the use of predictive information judgments impacts decision making in search, based on an anticipation of a page's value before viewing it (Rieh, 2002;Griffiths & Brophy, 2005).Cognitive search models rarely explore the impact of predictive judgments. Most studies are based on tasks defined by researchers in experimental settings that are difficult to generalize to professional contexts or real use (Thatcher, 2006; information judgments during real instances of information search and...

“…Currently there is a small but growing body of work using process-oriented or otherwise ecologically grounded approaches that may be valuable for future research efforts. [53,54] For example, some research focuses on variations in human search strategies in database environments [55] such as differences in the processes of children and adults (Bilal and Kirby, 2002). [61] In these studies, key results indicate that specific information search strategies can be identified that tend to systematically vary with age.…”
