The aim of the first research was to examine the role of EI in regulating the affective response to a potentially threatening video and relation to brain electrical activity. The second study, conducted at the University of Cincinnati, explored the role of emotion in the search for information relevant to decision-making. The third study was devoted to the evaluating the sensitivity of a range of EEG indexes of engagement to time-on-task effects and to workload manipulation (cueing) during vigilance task performance.
