Outline of Final Research Achievements

In a social interaction, some people are more suspicious of others’ words and behaviors than other people. This suspicion in turn could cause an aggressive behavior to the others. The current study developed a test battery with photo pictures that can measure the extent that people are suspicious of others’ behaviors. In addition, we conducted an electrophysiological experiment, investigating the relationship between the degree of people’s unjustified suspicion measured by our test battery and the activation level of their anterior cingulate cortex reflected in the Error-Related Negativity (ERN), an event-related brain potential. The results revealed that the more people were suspicious of others’ behavior, the lower the amplitude of ERN. The amplitude of ERN reflects the activation of their anterior cingulate cortex. These results suggest that individuals with a strong suspicious trend may have functional deficits of self-monitoring.
