Exploring the Effect of Mental Demand in Web Searches: A Pilot Study

Kyoungsik Na
2014 Journal of the Korean Society for Library and Information Science

Effects of task and domain on searcher attention

Dmitry Lagun, Eugene Agichtein
2014 Proceedings of the 37th international ACM SIGIR conference on Research & development in information retrieval - SIGIR '14  
For example, we find that the mean fixation duration, a common indicator of cognitive load, varies significantly across domains (e.g., mean fixation duration in the Social Network domain exceeds that of  ...  In this paper we present, to best of our knowledge, the first cross-domain comparison of search examination behavior and patterns of aggregated attention across Web Search, News, Shopping and Social Network  ...  [7] quantified distribution of user attention in Web Search domain and identified famous "F-shaped" pattern.  ...

Assessing Cognitive Load on Web Search Tasks [article]

Jacek Gwizdka
2010 arXiv   pre-print
We examined cognitive load from the perspective of primary and secondary task performance. A controlled web search study was conducted with 48 participants.  ...  Assessing cognitive load on web search is useful for characterizing search system features and search tasks with respect to their demands on the searcher's mental effort.  ...  Work tasks as unit for analysis in information seeking and retrieval studies.  ...

Cognitive Activity during Web Search

Md. Hedayetul Islam Shovon, D (Nanda) Nandagopal, Jia Tina Du, Ramasamy Vijayalakshmi, Bernadine Cocks
2015 Proceedings of the 38th International ACM SIGIR Conference on Research and Development in Information Retrieval - SIGIR '15  
By using this approach, we identified that the cognitive activities during the three stages of Web searching are different, with various brain areas becoming more active during the three Web search task  ...  Such knowledge is essential for better understanding of the cognitive demands imposed by the search system and search tasks.  ...  Similarly, Gwizdka [5] used dual-task method to demonstrate dynamic changes in cognitive load in the task stage level of Web searching, reporting significantly higher average cognitive load during query  ...

Using temporal patterns of interactions to design effective automated searching assistance

Bernard J. Jansen
2006 Communications of the ACM  
Certainly, the cognitive load of information seeking in these contextual situations is high.  ...  The interjection of assistance into the search process may be too much of a cognitive load, requiring a task switch from focusing on the search process to mentally processing the assistance.  ...  Certainly, the cognitive load of information seeking in these contextual situations is high.  ...

Supporting Ideation by Integrating Exploratory Search, Browsing, and Curation

Yin Qu
2016 Proceedings of the 2016 ACM on Conference on Human Information Interaction and Retrieval - CHIIR '16  
This research integrates exploratory search, browsing, and curation in information-based ideation (IBI) environments, to support users finding, discovering, and combining web content.  ...  Methods, techniques, and findings developed through this research have the potential to transform infrastructures and human experiences of the web.  ...  However, despite this inherent relationship, prior tools separate exploratory search, browsing, and curation. This forces users to split attention, resulting in extraneous cognitive load [3, 26] .  ...

Diane Nahl
2006 Proceedings of the American Society for Information Science and Technology  
Affective load was higher in those who reported low values of affective coping skills and who had either high or low cognitive assessment scores.  ...  Affective load (AL), a compound variable consisting of uncertainty and technophobia measures, was found to be present in a variety of simple and complex information tasks integrated into upper-division  ...  Affective load theory in information behavior predicts that such an interaction must exist. The group was divided at the mean of the distribution of the cognitive task scores.  ...
