| Research Abstract |
In this study, we investigated how humans detect and recognize threat-related information in the environment. We conducted experiments that used angry, neutral, and happy facial expressions; angry faces were used as threat-related stimuli. We manipulated task load, and examined whether threat-related information affects executive cognitive processes, even when they are completely task-irrelevant. The results showed a significant effect of threat-related information on the task in the high load condition. When the task load was high and angry faces were presented in the same display, cognitive processing of the central task was disrupted. These results indicate that threat-related information is difficult to avoid, and that it is processed without intention. Also, a negative correlation was revealed between individual anxiety levels and detection sensitivity.
