The Effects of Manipulating Task Determinability on Search Behaviors and Outcomes

Robert Capra, Jamie Arguello, O'Brien, Heather, 1977-, Yuan Li, Bogeum Choi
One view of task complexity is through the lens of a priori determinabilitythe level of uncertainty about task outcomes and processes experienced by the searcher.  ...  An important area of IR research involves understanding how task characteristics influence search behaviors and outcomes.  ...  RQ4: What is the effect of task version on participants' search behaviors?  ...

Top-down search strategies determine attentional capture in visual search: Behavioral and electrophysiological evidence

Martin Eimer, Monika Kiss
2010 Attention, Perception & Psychophysics  
When responses were required to only one of the two color singletons, the same cues no longer elicited behavioral spatial cuing effects, and the N2pc to these cues was attenuated and delayed, in line with  ...  Results demonstrate that the ability of visual singleton stimuli to capture attention is not simply determined by their bottom-up salience, but strongly modulated by top-down task sets.  ...  A potentially important factor that may determine the strength of this residual capture effect is the type of search array used.  ...

Is my Effort Worth IT? Investigating the dual effects of Search Cost on Search Utility

Fei Liu, Bo Sophia Xiao, Eric T. K. Lim, Chee-Wee Tan
2016 Pacific Asia Conference on Information Systems  
We therefore draw on Information Foraging Theory (IFT) to disentangle the dual role of search cost in shaping the utility of information search.  ...  By analyzing the behavioral data generated in the experimental process, we discover that search cost reduces the expected search utility while improving the yield of search space.  ...  By analyzing the behavioral data generated in the experimental process, we aim to answer the following research questions: First, how does search cost exert dual effect on search utility?  ...

Eye-tracking analysis of user behavior and performance in web search on large and small screens

Jaewon Kim, Paul Thomas, Ramesh Sankaranarayana, Tom Gedeon, Hwan-Jin Yoon
2014 Journal of the Association for Information Science and Technology  
We analyze web searches with 2 task types on 2 differently sized screens: one for a desktop and the other for a mobile device.  ...  In addition, we examine the relationships between search performance and several search behaviors to allow further investigation of the differences engendered by the screens.  ...  Furthermore, we investigate the effect on search speed of some of the differences in search behavior.  ...

Peer Effects on Real-Time Search Behavior in Experimental Stock Markets

Xuejun Jin, Xue Zhou, Xiaolan Yang, Yiyang Lin
2021 Frontiers in Psychology  
By randomly assigning subjects into pairs and presenting them with real-time information on their peers' searches, we investigated the effects of peers' decisions on search behaviors.  ...  However, this peer effect did not exist when subjects had access to feedback information on the ex-post best response.  ...  Risk attitude and cognitive ability are two major determinants of search behaviors.  ...

The Effects of Search Environment and Task Realism on Search Behavior

Xioyan Niu, Ann M. Bisantz
2001 Proceedings of the Human Factors and Ergonomics Society Annual Meeting  
Search tasks were defined based on a qualitative, three-stage model of search behavior.  ...  Additionally, behavior was also similar across the structured vs. self defined search tasks, suggesting that aspects of search engines and user search behavior can be tested in a controlled setting and  ...  For the self-directed search task, there was a significant effect of search environment on search time, and a significant effect of search stage on search time, the number of items checked, ratings of  ...

Developmental changes in visual search are determined by changing visuospatial abilities and task repetition: a longitudinal study in adolescents

Rudolf Burggraaf, Jos N. van der Geest, Ignace T. C. Hooge, Maarten A. Frens
2019 Applied neuropsychology. Child  
We analyzed the association between changes in visuospatial ability and changes in visual search performance and behavior and estimated additional effects of age and task repetition.  ...  We found that both the increase in age and the yearly repetition of the DOT had a positive effect on visuospatial ability.  ...  I am also grateful for the students, teachers, conrectors, and rector of Gemeentelijk Gymnasium Hilversum.  ...

Examining the effects of task topic familiarity on searchers' behaviors in different task types

Jingjing Liu, Chang Liu, Nicholas Belkin
2013 Proceedings of the American Society for Information Science and Technology  
In this paper, we examined the effects of information searchers' familiarity with task topics on their search behaviors, in different task types.  ...  Each participant searched on four tasks varying along four task facets: task product (being factual or a mix of intellectual/factual), level (the needed information being the whole document or a segment  ...  One stream of research examines the effect of task type on user behaviors in searching and has found significant effects.  ...
