EEG markers of future cognitive performance in the elderly.
This exploratory follow-up study investigated whether EEG parameters can predict future cognitive performance. Forty elderly subjects, ranging from cognitively unimpaired to those with Alzheimer disease underwent EEG registration at baseline and neuropsychological examination at both baseline and follow-up. We assessed relations between EEG measures and future cognitive performance (i.e., globa...
متن کاملModeling temporal sequences of cognitive state changes based on a combination of EEG-engagement, EEG-workload, and heart rate metrics
The objective of this study was to investigate the feasibility of physiological metrics such as ECG-derived heart rate and EEG-derived cognitive workload and engagement as potential predictors of performance on different training tasks. An unsupervised approach based on self-organizing neural network (NN) was utilized to model cognitive state changes over time. The feature vector comprised EEG-...
متن کاملCorrelation between Expected Workload and EEG Indices of Cognitive Workload and Task Engagement
As a Human Computer Interaction (HCI) designer, it is important to understand the cognitive workload level (mental demand) of an operator while performing a task. A particular concern about operator workload stems from the increased potential for errors when cognitive workload gets too high. The Office of Naval Research Disruptive Technologies Opportunity Fund, is sponsoring research investigat...
متن کاملEEG-Related Changes in Cognitive Workload, Engagement and Distraction as Students Acquire Problem Solving Skills
We have begun to model changes in electroencephalography (EEG)derived measures of cognitive workload, engagement and distraction as individuals developed and refined their problem solving skills in science. For the same problem solving scenario(s) there were significant differences in the levels and dynamics of these three metrics. As expected, workload increased when students were presented wi...
متن کاملSTANCE AND ENGAGEMENT DISCOURSE MARKERS IN JOURNAL’S “AUTHOR GUIDELINES”
Over the past decade, there has been an increasing interest in the study of interactional metadiscourse markers in different contexts. However, not much research has been conducted about the discourse of journal author guidelines, especially the use of meta-discourse markers in this genre. Therefore, this corpus-based study had three main aims: 1) to delve deep into the types, frequencies and f...
