One such attribute is cognitive ability. Because information search is primarily a cognitive activity, understanding the extent to which variations in cognitive abilities impact search behaviors and outcomes is especially important. We describe a study in which we explore how people's cognitive abilities affect their search behaviors and perceptions of workload while conducting search tasks with different levels of complexity. Twenty-one adults from the general public completed this study. We assessed participants' associative memory, perceptual speed, and visualization abilities and also measured workload. To evaluate the relationship between cognitive ability, task complexity and workload, we conducted three separate mixed factor ANOVAs corresponding to each of the abilities. Our results suggest three important trends: (1) associative memory ability had no significant effect on search behavior and workload, (2) visualization ability had a significant effect on search behavior, but not workload, and (3) perceptual speed had a significant effect on search behavior and workload. Specifically, participants with high perceptual speed ability engaged in more search activity in less time and experienced less workload. While the interactions were not significant, the differences were more pronounced for more complex tasks. We also found a significant relationship between task complexity and workload, and task complexity and search behaviors, which corroborates previous research.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131419711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Guided by Information Foraging Theory and Search Economic Theory, five competing hypotheses relating to the behaviours of searchers in the presence of delays are considered and examined in the context of ad-hoc topic retrieval. A between-subjects laboratory study with 48 undergraduate subjects was conducted. Subjects were randomly assigned to one of four conditions that varied the type of delay experienced. When faced with query response delays, subjects did not examine more documents per query as expected. However, when the total amount of time spent per query (a combination of delay and querying time) increased, subjects did examine more documents per query. When faced with document download delays, subjects did not spent more time within documents. Subjects however did spend longer within documents when subjected to both query and document delays. We found a strong and significant correlation between query time (independent of delay) and the interactions of subjects in terms of the number of queries posed, the number of documents examined, and the depth to which subjects went. These findings contrast with previous works on how delays affect search behaviour, and suggest that the theory needs to be refined to make more credible predictions relating to search behaviours.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132988051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these studies could not exclude the possibility of the influence of instructions or time-dependent changes. In this study, we have compared differences between concept maps created before and after a search condition and a non-search condition to reveal whether these changes are due to searching. In the experiment, participants were required to gather information on the Web in preparation for a group discussion. The participants were divided into two groups representing two tasks, convergent and divergent tasks. The convergent task required gathering web pages for a specific and detailed discussion, and the divergent task required gathering web pages for a wide-ranging discussion. Participants performed each task under search and filler conditions. In the search condition, they searched the Web. In the filler condition, they played a typing game on a PC. We compared pre- and post-task concept maps. Analysis of the number of nodes in the concept maps indicated that changes in the search condition are significant, whereas changes in the filler condition are insignificant. The analysis of the number of nodes at each distance from the center nodes in the concept maps showed that tasks had a greater effect in the search condition than in the filler condition. Finally, we consider whether the experimental results support our hypotheses.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133973892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
