Summary: The study identified that eye-measures were the most sensitive in detecting changes in intrinsic cognitive load, followed by heart and lungs, skin, and brain measures, with subjective measures having the highest levels of validity. Therefore, a combination of physiological and subjective measures is concluded to be the most effective in detecting changes in intrinsic cognitive load.

Summary: This study investigates the potential of using EEG recorded inside and around the human ear to determine levels of attention and focus. The results suggest that neural oscillations recorded with ear-EEG can differentiate between levels of cognitive workload and working memory when multi-channel recordings are available.

Summary: The use of multimedia learning is common in modern education, and designing multimedia content that imposes optimal cognitive load is important for efficient learning. This study explores the use of EEG signals to measure instantaneous cognitive load during multimedia learning tasks and builds a model for load assessment. The findings show that EEG signals can be used as a tool to measure cognitive load in educational videos, aiding in the development of more effective instructional content.

Summary: The concept of mental workload is largely associated with cognitive load theory, describing three types of load in assessment tasks. Studies show that high intrinsic and extraneous load in assessments may interfere with assessors' attention and working memory, leading to poorer quality assessment. Therefore, reducing these loads within assessment tasks is crucial for enhancing assessment quality, especially in pharmacy education.

Summary: Decoding the subjective perception of task difficulty can help improve operator performance and automatically optimize the task difficulty level. This study utilized EEG signals to discriminate different compound cognitive states and examined the latency of changes in the user's compound state in adaptive HMI system design. The results suggest that the latency of changes in the user's compound state between different tasks is an important factor to consider in building adaptive HMI systems.

Summary: The study found that EEG measurements collected by MUSE 2 are not very useful indicators of cognitive workload changes in our setting, while eye movement measurements collected by Tobii Pro Nano are effective for monitoring workload fluctuations and identifying interface design issues in a smartphone setting, with maximum pupil diameter being the main indicator of workload surges.

Summary: The purpose of this study was to evaluate the acute and mid-term effects of a dynamic meeting environment on brain activity, cognitive performance, heart rate variability, sleepiness, mental workload, and local experienced discomfort in healthy adults. The results showed that the use of a dynamic meeting environment can help maintain vigilance performance and improve alertness. Additionally, the mid-term use of such an environment may reduce mental and physical fatigue.

Summary: Assessing mental workload is crucial for avoiding unintended negative consequences in critical situations. This study differentiated two types of mental workload and manipulated them independently using a modified video game, finding that fixation-related parameters can be used to index mental workload at different stages of mental processing.

Summary: Mental workload has a significant impact on an individual's performance in real-world tasks, leading to potential errors. This study investigated the effects of workload on brain network organization using EEG data. The results showed that higher workload led to reduced clustering coefficient, characteristic path length, and small-worldness metrics. Additionally, the brain network reorganized in a task-independent manner with increasing mental load. The network metrics were also effective in classifying workload levels.

Summary: The study investigated the effectiveness of node-link diagrams in visualizing networks of certain complexities. It found that people have difficulty finding the shortest path in high-density node-link diagrams with more than 50 nodes and even low-density graphs with more than 100 nodes. The research also observed changes in cognitive load, as well as the impact of global network layout features and shortest path features on task difficulty.

Summary: This study systematically reviewed the assessment methods of usability and cognitive workload in the use of exoskeletal devices for motor rehabilitation. A total of 18 distinct assessment methods were identified, with 15 aimed at assessing usability and 3 aimed at assessing cognitive workload. Some of the identified methods showed good psychometric properties and were proven to be appropriate for assessing usability and cognitive workload in exoskeleton-based rehabilitation.

Summary: This study investigated the effect of mental workload on the causal influence brain regions exert over each other during multitasking. The results showed that with increased workload, causal connections shifted from the left to both sides of the brain, and the connectivity strengths could predict subtask performances. By studying the brain dynamics of mental workload, a predictor that supplements subjective self-report measures can be developed.

Summary: As vehicular automation becomes more advanced, human drivers are faced with the increasing demand to monitor and handle rare automation failures. This study investigates the differences in individual susceptibility to vigilance decrement during assisted driving with adaptive cruise control, using an objective neurometric of mental workload. The findings suggest that the measured neurometric is associated with the magnitude of drivers' behavioral changes, highlighting its potential use in identifying higher risk drivers and improving driver-vehicle interaction systems for enhanced safety.

Summary: Long-haul truck drivers are prone to severe levels of accumulated sleep loss while working irregular shifts, but they can catch up on lost sleep, especially during days off. The study found that 45% of the drivers experienced accumulated sleep loss of over 6 hours at least once. Morning shifts were associated with a shorter accumulated sleep loss compared to day or evening shifts.

Summary: This study investigated the causes of sleepiness among tram and long-haul truck drivers and found that the main reasons for sleepiness differ between the two groups. While drivers commonly reported sleep loss and insufficient rest breaks as causes of sleepiness, truck drivers primarily attributed their sleepiness to time of day and sleep loss.
