In 1951, Solomon Asch performed several conformity experiments. The purpose of these studies was to investigate conformity in a group environmental situation. The purpose of these experiments was to see whether an individual would be influenced by public pressure to accept the incorrect answer. Asch believed that conformity is reflected in a relatively rational process in which people are driven to change their behavior. Asch designed experiments to measure the pressure of a group situation on individual judgment. Asch wanted to show that conformity can indeed play an important role in disbelieving our senses. Asch began his experiment by putting one of the participants at ease. He asked a series of elementary questions which the four confederates answered correctly, then the fifth person also answered the question correctly. This in a sense gave the participant a false interpretation of the real thinking behind Asch's real experiment. Participants were asked to compare, identify, and match one of three lines on the right card with the length of the line on the left card. This task was repeated several times to obtain a faithful picture of the data collected. Participants received no explicit request to comply, as they received no physical or verbal coercion to do so. The specific hypothesis focused on the idea: “whether group pressure can influence and influence individuals' perception, decision-making and attitudes”. The independent variable will be “Procedure” and the dependent variable is “the level of compliance has changed”. The experiments were quite simple, as there was a seemingly innocuous task to perform and participants were asked to choose the estimate of the length of one line over two… halves of the paper… y decreased. Although Asch conducted many variations on his conformity test, and was criticized as too simplistic to accurately represent true conformist behavior, his experiment has stood the test of time and scrutinyWorks CitedAnderson, M, L, Taylor, H, F (2008).
