Factors influencing trust, reliance, performance and cognitive workload in human-agent collaboration
… where they are used to alleviate the cognitive load of human operators while increasing task performance. Automated agents are present in a variety of domains, from safety critical environments to leisure-oriented activities, and more and more, they are being considered as a virtual …

Effects of retinal disparity depth cues on cognitive workload in 3-D displays
… to investigate the influence of stereopsis upon cognitive workload. This dissertation is a description of two experiments using 3-D images presented on a Tektronix SGS 620 field-sequential stereoscopic CRT. Comparisons were made between presentations incorporating monocular cues only (2 1/2-D) …

An Examination of the Cognitive Workload Associated With Conducting in an Instrumental Music Context
… dual-task episodes, suggesting the presence of a cognitive bottleneck. Subjects' attentional resources allocated towards conducting gesture gradually increased throughout the study, indicating both task preference as well as perhaps increased comfort with the prescriptive, recurrent task of …

Aging and semantic integration in sentence processing: Testing the cognitive workload of wrap-up
The current study investigated the cognitive workload of sentence and clause wrap-up in younger and older readers. A large number of studies have demonstrated the presence of wrap-up effects, peaks in processing time at clause and sentence boundaries that some argue reflect attention to …

The effects of time of day and circadian rhythm on performance during variable levels of cognitive workload
… collected to objectively measure participants’ workload. Task demands were altered throughout the testing period to expose participants to both high and low workload conditions. Additionally, individual differences in circadian rhythm were explored by assessing participants’ circadian typology. …

Cross-correlation based performance measures for characterizing the influence of in-vehicle interfaces on driving and cognitive workload
<p>Driving is a cognitively loading task which requires drivers' full attention and coordination of both mind and body. However, drivers often engage in side activities which can negatively impact safety. A typical approach for analyzing the influences of side activities on driving is to conduct …

Using Real-Time Physiological and Behavioral Data to Predict Students' Engagement during Problem Solving: A Machine Learning Approach
… (EEG) estimates of attention and cognitive workload captured as students solved math problems could be used to predict success or failure at solving the problems. Students solved a series of SAT math problems while wearing an EEG headset that generated estimates of sustained …

Behavioral and Physiological Measures of Driving Across the Spectrum of Alzheimer’s Disease
… that requires simultaneous execution of several cognitive, visual, and motor functions to respond to a constantly changing environment. Cognitive impairment (CI) associated with Alzheimer’s disease (AD) may negatively impact the ability to drive, leading to a higher risk of motor vehicle crashes …

Enhancing Online Yoga Instruction: Evaluating the Effectiveness of Visual Augmentations for Performance Assessment
… The Skeleton augmentation led to increased cognitive workload, as indicated by larger pupil diameters. The Contour alone augmentation was less effective for visual search based on the usability ratings, and combining Contour with Skeleton did not offer notable improvements. Simpler …

Decision aids in airborne command and control platforms
… in an intuitive style that eases the commander's cognitive workload and speeds comprehension. Recent studies comparing different types of displays support this theory. Because commanders in airborne command and control platforms require a detailed understanding of a three dimensional environment, …
