Abstract : In this report, we developed a laboratory model to test hypotheses concerning the disruptive effects of emotional stimuli. The research as of the computerized emotional Stroop task. We discovered that the task was sensitive to two important elements of stress resistance, threat and habituation. The Stroop task is sensitive to the nature of the stimuli, namely that threatening stimuli can be distinguished from nonthreatening stimuli and that with stimulus repetition the stimuli show effects of habituation. Important findings emerged from the research in the following areas. Time pressure and task difficulty. One of the most important findings demonstrates the importance of time pressure and information load on overall performance and the adaptive process that eliminates emotional interference. When an individual is under time pressure and/or is performing a difficult task, there is greater emotional interference than when there is no time pressure or the task is easy. The important role that time pressure and task difficulty play in tasks such as this has not, to this point, been acknowledged. Stress resistance, Attention, Emotional Stroop task, Time pressure.
