What was the aim of Mori and Arai's (2010) study?

The aim of Mori and Arai's study was to explore conformity without the use of actors. This was a significant aspect of their research, as prior studies, such as Asch's classic experiments, used confederates (actors playing a role) to elicit conformity responses from participants. Mori and Arai developed an innovative method that employed different glasses and varied perceptions of visual stimuli, allowing them to investigate conformity effects without the potential biases introduced by actors. This method provided a more authentic context for examining how individuals conform to group pressure under realistic conditions, enhancing the ecological validity of the findings. Their approach emphasized the idea that conformity could be studied effectively without the need for deception through the inclusion of actors in the experimental design.
