Examining the Effects of Cognitive Authority and Peer Advice on Web Information Interactions (Project Co-leader), Spring 2017-ongoing
Individuals’ Web search behavior can be influenced by a number of factors such as features and functions of a search engine as well as search education. In contrast to the long-lasting attention to the algorithm and interface dimensions of search, the potential effects of user education on search behavior have been understudied. We ran a three-session field-lab-combined study to examine the effects of user education from two sources – peer advice and cognitive authority. We also tested if these behavioral effects lasted for a short period of time when the explicit search tips were removed. This research has implications for the design of Web search interventions that can improve search behaviors and outcomes.

Success and Failures in Information Seeking Episodes (Project Leader), Spring 2016- Spring 2018
People constantly face obstacles and failures in various types of information seeking episodes. These are often attributed to either the information seeker or the system/service being used for finding information. What is often ignored in such investigations is the context of the tasks that trigger information seeking or the strategies being used by the information seeker. A careful examination of the links between information seeking barriers and outcomes is needed. In this project, we look at where and why information seeking episodes succeed or fail, and how those successes/failures relate to the greater context of the tasks, the strategies/methods people employ, and the barriers/challenges they encounter.
