  • CLIS - Continuous Assessment of Cognitive Load in Information Seeking This project investigates cognitive load experienced by web information searchers. Cognitive load is affected not only by a person’s abilities and a task they perform, but also by a task stage and user interface. Eye movement and EEG data is collected from users engaged in information seeking in order to gain a new understanding of cognitive demands imposed by information search and to develop a measurement framework for non-intrusive assessment of cognitive load. Funded by IMLS Career award to Dr. Gwizdka: RE-04-11-0062-11.
  • LaSaL - Learning about Search as Learning: | Dr. Jacek Gwizdka
  • Consumer Health Information Evalation: Understanding Consumers: Quality Evaluation of Online Health Information Using a Mixed-Method Approach | Dr. Yan Zhang & Dr. Jacek Gwizdka (UT Austin Co-PIs) with Dr. Carla Teixeira Lopes (U Porto Co-PI)

Previous Projects


  • Multi-tasking - Or should we say “task switching?” Recent doctoral grad Ji Hyun Park has expanded our work on humans’ ability to multi-task (see Park, J. H., & Bias, R. G. [2012]). Understanding human multitasking behaviors through a lens of Goal-Systems Theory. Paper presented at the annual meeting of the Association for Library and Information Science Education, Dallas, January), and defended her dissertation, Flow in Multitasking: The Effects of Motivation, Artifact, and Task Factors, in July, 2014.


  • Which Usability Engineering Method When? Project PI: Dr. Randolph Bias. We are frustrated that there is so little empiricism driving the choice of which usability engineering method might yield the best bang for the dollar and hour invested.
