| Outline of Annual Research Achievements |
The main goal of the present study was to answer this question. In the present study, we collected fMRI data while participants were performing a modified random dot motion task. The experimental setting and the instruction lured them into believing that their task and their partner's task were synchronised. Therefore, we were able to show them partner's answer to each stimulus. Participants observed the same stimulus twice and made the judgements twice as well. One stimulus appeared before, and another one appeared after receive the partner's answer or the random answer. We trained classifier to identify neural patterns in V1, V2, V3, and MT while each pattern corresponds to one moving direction participants perceived and then used the classifier to test whether neural patterns were the same or different in trials when participants showed conformity to partner or to random answer. The results showed that when participants change their answer from 'moving right' to 'moving left', the neural patterns in V1, V3 and MT changed from the 'right pattern' to the 'left pattern', and vice versa. Therefore, our results suggest that one of the reasons why people show social conformity in a visual perception task is because social influence penetrate early perception processes, and it makes people perceive differently.
