1. Figure 13 Cognitiv training of push with animate cube according to training action selected Finally you are prompted to accept or reject the training recording Ideal Cognitiv detection performance is typically achieved by supplying consistent training data i e a consistent mental visualization on the part of the user across several training sessions for each enabled action The ability to reject the last training recording allows you to decide whether you were able to remain mentally focused on the appropriate action during the last training session Alternatively you may press the Abort Training button to abort the training recording if you are interrupted become distracted or notice problems with the EPOC Neuroheadset contact quality indicators during the recording A training session is automatically discarded if the wireless signal strength or EEG signal quality is poor for a significant portion of the training period A notification will be displayed to the user if this has occurred 3 3 4 Training Neutral The Neutral action refers to the user s passive mental state one that isn t associated with any of the selected Cognitiv actions While training Neutral you should enter a mental state that doesn t involve the other Cognitiv actions Typically this means engaging in passive mental activities such as reading or just relaxing However to minimize false positive Cognitiv action results i e incorrect reporting2. The Affectiv Suite panel contains two graph panes displaying the three Affectiv detections instantaneous and long term average time scales The top chart is configured to plot 30 seconds of data for the Engagement Meditation and Instantaneous Excitement detections The bottom chart defaults to display 5 minutes worth of data for the Long Term Engagement Meditation and Excitement detections The values that are plotted on the graphs are the output scores returned by the Affectiv detections 3 2 3 Affectiv Suite Detection Details Scoring behavior In general the greater the increase in physiological arousal the greater the output score for the detection Instantaneous Excitement is experienced as an awareness or feeling of physiological arousal with a positive value Excitement is characterized by activation in the sympathetic nervous system which results in a range of physiological responses including pupil dilation eye widening sweat gland stimulation heart rate and muscle tension increases blood diversion and digestive inhibition The Instantaneous Excitement detection is tuned to provide output scores that more accurately reflect short term changes in excitement over time periods as short as several seconds Related emotions titillation nervousness agitation Long Term Excitement is experienced and defined in the same way as Instantaneous Excitement but the detection is designed and tuned to be more accurate when measuring changes i
