Sažetak
Multimodal paradigm for cognitive-emotional elicitation, estimation and regulation may strengthen military training and enhance selection process. It includes multiple sessions involving mission-relevant audio-visual stimulation and simultaneous measurement of the trainee's multimodal physiological, facial and vocal response. The initial audio-visual adaptive stimulation screening sequence contains personalized mission-relevant semantically and emotionally congruent static pictures and sounds, based on the initial interview with the soldier conducted by military psychologists. After each stimulus as well as the entire sequence, the soldier provides subjective emotional ratings in terms of valence, arousal and discrete emotions. These subjective ratings and recorded multimodal response (physiology, voice, and facial expressions) represent initial information regarding the soldier's appraisal of mission-relevant stimuli. Subsequent sessions use dynamic stressful video clips captured in real missions, with soldier's entire multimodal response measurements. To maximize training relevance, video clips are personalized and can be mixed with instructions of the commander and potentially other unit members. Additionally, mission-relevant audio-visual interactive tasks are delivered separately and in conjunction with stressful video clips, to strengthen the soldier's cognitive-emotional capabilities. Offline analysis of the soldier's multimodal response can be additionally enhanced by fMRI to the presented pictures, sounds, video clips, and interactive tasks, to reveal changes that occur as a consequence of training. Parameters of the soldier's cognitive-emotional state estimators are tuned continuously in real-time based on physiology, voice, and facial expressions. Aggregate information from these cognitive-emotional state estimators may assist instructors during real-time decision-making when striving to present the most appropriate stimuli for the trainee's current multimodal response. Such stimuli generation based on expert knowledge and experience in cognitive-behavioral stress inoculation training is implemented in our closed-loop audio-visual adaptive stimulation system.
