Final answer:
Psychologist Solomon Asch conducted experiments in 1955 to study conformity. He found that participants conformed and gave incorrect answers when faced with unanimous wrong answers from the rest of the group. Group size also had an impact on the pressure felt to conform.
Step-by-step explanation:
Psychologist Solomon Asch conducted experiments in 1955 to study conformity. In his experiments, participants were shown a series of printed line segments and were asked to identify which line segment most closely resembled a fourth line segment in length. Asch's research showed that when faced with unanimous wrong answers from the rest of the group, participants conformed and gave incorrect answers to avoid contradicting the group. He also found that group size had an impact on the pressure felt by the participants to conform.
