A neuroergonomic approach to evaluating mental workload in hypermedia interactions

Saccadic Eye Movement Metrics Reflect Surgical Residents' Fatigue

“…S1, available at http://links.lww.com/SLA/A479; for additional analyses on the effects of time-on-duty on saccadic parameters during task performance, see Supplemental Digital Content Table S2, available at http://links.lww.com/SLA/A479). These data are consistent with previous reports of the effects of fatigue on saccadic metrics, 17,19 now applied, for the first time, to the health care field.…”

“…15,16 Such questionnaires are relatively easy to administer and interpret but have methodological caveats, including the following: (1) the usual off-line administration does not allow for continuous evaluation of physicians' performance; (2) test sensitivity is generally insufficient to signal small variations in work demand; and (3) personal and motivational factors (eg, social acceptance) can bias test scores. 17,18 Thus, the sensitivity and objectivity of work demand assessment in ecologically valid surgical scenarios remains a major challenge in the health care field. [19][20][21] Objective eye movement metrics have been used to differentiate novice from expert surgeons, to quantify and to study surgeons' scanning behavior, [22][23][24] to assess concentration during surgical performance, 25,26 and as a measure of laparoscopic surgical skills.…”

Internet cognitive failure relevant to self-efficacy, learning interest, and satisfaction with social media learning

“…Recent experiments (e.g., Di Stasi, Antolí, Gea, & Cañas, 2011) have demonstrated that cognitive ability affects the understanding of hypertext contents. Given the presence of these features in learning guitar available on social media, the structure and content of YouTube offers a greater degree of user control because the learner has to determine and shift the content choices that place additional demands on cognitive executive functions (Klois, Segers, & Verhoeven, 2013).…”

The effect of cognitive abilities on information search for tasks of varying levels of complexity

“…They combined workload scores with pilot test results as well as task performance analysis (i.e., time-on-task) to determine the success of their manipulation of task difficulty. Di Stasi, et al [17] compared different search tasks and found that goal-oriented (fact-finding) shopping tasks required more workload than experiential ones (information-gathering).…”
