“…Most of the experiments use subjective measures and suffer methodological limits of such subjective measures [51]. In the research area on information search tasks with hypertexts, objectives measures based on navigation behaviors were developed [52,53]. Future experiments should include such objective measures in addition to subjective measures.…”

An exploratory experiment was carried out in order to question the relationships between prior knowledge, comprehension performance, on-line processes and disorientation in a non-linear document (hypertext). 14 participants read a non-linear document about a virus' infectiousness process which imposed to learners to construct themselves their reading orders and also a structure of the document. Correlational analyses were conducted to test the relations between the variables. Results indicated that the prior knowledge was positively correlated with the learning performance, the coherence of the reading orders, and negatively with the time spent to construct a document structure. Correlations between the prior knowledge and the disorientation indicated a marginal negative relation. The results stressed also significant correlations between the on-line processes and the comprehension performance. Interestingly, the observed correlations between the on-line processes and the disorientation suggested that the disorientation was function of difficulties to construct the document structure rather than difficulties to construct a reading order. The present study highlighted how prior knowledge constitutes resources to process non-linear documents and what type of on-line processes are related to disorientation.

“…Hence, the promise of dual-task (DT) method that allows for an indirect objective assessment of mental effort on the primary task. Only few studies employed this method to assess cognitive load in online search tasks (e.g., [14,15,18]). The article discusses the dual-task method as the technique for assessing cognitive load on web search tasks and presents research that *Address correspondence to this author at the Department of Library & Information Science, School of Communication and Information, Rutgers University, New Brunswick, NJ, USA; E-mail: WebCog@gwizdka.com contributes to better understanding of how objective task difficulty affects searchers' behavior and their perception of task difficulty.…”

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. It is also helpful for examining how individual differences among searchers (e.g. cognitive abilities) affect the search process. We examined cognitive load from the perspective of primary and secondary task performance. A controlled web search study was conducted with 48 participants. The primary task performance components were found to be significantly related to both the objective and the subjective task difficulty. However, the relationship between objective and subjective task difficulty and the secondary task performance measures was weaker than expected. The results indicate that the dual-task approach needs to be used with caution.

“…Once the participant thought that they had found the target they clicked on the "Verify" button to open the target to verify whether the revisit had been successful. If a target page was not found within 3 minutes of the item being selected in the dialog window list then the trial was terminated as unsuccessful (Gwizdka and Spence, 2007).…”

This research addresses the general topic of "keeping found things found" by investigating difficulties people encounter when revisiting webpages, and designing and evaluating a novel tool that addresses those difficulties. The research focused on occasional revisits -webpages that people have previously visited on only one day, a week or more ago (i.e., neither frequently nor recently). A three-month logging study was combined with a laboratory experiment to identify ten underlying causes of participants' revisiting failure. Overall, 61% of the failures occurred when a webpage had originally been accessed via search results, was on a topic a participant often looked at, or was on a known but large website. Then we designed a novel visual Web history tool to address the causes of failure and implemented it as a Firefox add-on. The tool was evaluated in a three-month field study, helped participants succeed on 96% of revisits, and was also used by some participants to review and reminisce about their "travels" online. Revised versions of the tool have been publicly released as the Firefox add-on MyWebSteps. RESEARCH HIGHLIGHTS• Identifying the underlying causes of failure when people revisit webpages.• Providing evidence how MyWebSteps helped users overcome those causes.
