In the studies conducted by Muzafer Sherif, participants who were put into a dark room by themselves after being in a dark room with others continued to "see" movement in a stationary point of light even when no movement existed
How was this explained by Sherif? a) The adoption of the norm of the group continued to exert influence even when a person was alone. b) The residual effect of sensory memory continued to influence the participants' perception of what they were seeing. c) Groupthink was taking over, so people became unwilling to give a different answer than they had given in a group setting. d) Normative conformity was taking place, in that the participant wanted to feel like part of the group even when it meant giving a wrong answer.
