Objective: This study aims to investigate neurophysiological characteristics when people predict the preference of others using the minimum amount of information of others such as static face images. Background: For a successful social life, people need ability to predict preference of others. Many studies have shown that dorsal medial prefrontal cortex(DMPFC) and ventral medial prefrontal cortex (VMPFC) are activated when people predict the information of others. Our study intends to add neurophysiological evidence based on EEG to relate frontal cortical activity to the preference of static face images. Method: 20 female participants participated in the experiment (mean age= 21.86). 9 female facial images (age of 20’s)were used as target pictures along with item pictures for food and movie poster. In every trial, each target picture appeared on the screen for 3 seconds followed by an item picture for another3 seconds. EEG (Electroencephalogram) was recorded during the task session and preference was evaluated using a 4-point scale. Behavioral data of participants were categorized according to accuracy of preference. Result: Prediction of food preference did not result in statistically significant accuracy while prediction of movie preference showed significant accuracy. Event-related potential (ERP) analysis of EEG signals showed that high accuracy group revealed higher ERP amplitude than a low accuracy groupatFP1 and FP2 channels(P<0.05). Conclusion: The ERP results showed that the DMPFC area, which is related with empathy ability, was more activated in a group with a better face preference ability.
