What methodology did Mori and Arai (2010) use in their replication of Asch's study?

The methodology employed by Mori and Arai in their replication of Asch's study involved participants watching a video of a group making judgments. This approach allowed the researchers to maintain control over the experimental conditions while effectively simulating the social pressure that participants would have felt in Asch's original study. By using a video, the researchers were able to illustrate group dynamics and the influence of peer pressure on individual judgments in a more controlled setting.

The use of video is essential in this context because it creates a scenario where participants can observe group consensus and the effects of conformity without the potential biases that can arise from face-to-face interactions with real confederates. This method effectively tested the same psychological principles of conformity that Asch explored, but in a modernized and ethically sound format.
