Title:

Neuro-Physiological Evidence as a Basis for Studying Search

Speaker: Jacek Gwizdka

Affiliation:

  • School of Information at University of Texas, Austin, USA.

Abstract

Application of neuro-physiological (NP) methods for studying information search, retrieval and relevance judgment have emerged recently as critical areas of research. The broad motivation for using NP approaches is development of models for information search that go beyond behavioral data and account for physiological and neurological responses to information. I will briefly describe acquisition of NP evidence using three modalities eye-tracking, EEG, and fMRI. My recent research findings will serve as examples. I will present results that show differences in eye-tracking measures between reading relevant and not relevant documents and visits and re-visits to web pages. I will discuss dynamics of EEG and eye-tracking signals during reading and relevance judgments on text documents. I am going to close by offering critical observations regarding the promises and perils of using NP approaches in studying search behavior.

Short Bio

Dr. Jacek Gwizdka is an Assistant Professor and Information eXperience Lab co-director at School of Information at University of Texas, Austin. He studies human information interaction and retrieval and applies cognitive psychology and neuro-physiological methods to understand information searchers and improve search experience. He is particularly interested in creating models that describe and predict cognitive and affective phenomena in human information interaction. Recent projects investigate search as a learning process and employ eye-tracking and EEG in assessment of reading, mind-wandering and in inferring information relevance. Dr. Gwizdka is one of the pioneers of Neuro-Information Science. He conducted research at industrial labs (Xerox PARC, FXPAL, HP Labs). Dr. Gwizdka received M.Eng. degree in Electrical Engineering from the Technical University of Lodz, and M.A.Sc. and Ph.D. degrees in Industrial Engineering from the University of Toronto. He is as an Associate Editor of Interacting with Computers. Dr. Gwizdka is a senior member of ACM and a member of HFES and ASIST.
