Social Pressure and Perception

Introduction

Picture yourself in the following scenarios, you’ve answered an advert in the local paper to take part in an experiment for psychology purposes, you arrive along with others but not realising that you are the only true volunteer.  You are all placed in a darkened room and the only thing you can see is a pin point of light which tends to move (The Autokinetic Effect).  Then later your all asked how much the pin points of light moved and then compared the answers collected from the other volunteers (Stooges).  As an individual you give your answer which is different from your group answer.  Another experiment involves two cards, one contains a single vertical line and the other card contains three different lengths of vertical lines.  The end result in both of these experiments shows how we conform to others.  I’m going to explain in two ways in depth how we “Conform” to others, the “Self Concept” and “Obedience”.  At the end of this essay you will see that I’ve noted how important it is that we meet the BPS ethical guidelines when experiments like these are done.

Conformity

In 1935 a Psychologist called Sherif wanted to show how people conformed to other people’s ideas, so he used an experiment called the “Autokinetic Effect” and this involved placing the subjects in a darkened room with a pin point of light which would eventually move about.  Sherif asked the subjects to estimate how much the pin point of light moved and they all gave very different answers ranging from one to seven inches.  Each subject tended to make the same sort of judgement whenever they were tested.  For instance their answers for the next set of tests would be the same as the previous experiments.  These were the results that Sherif got when the subjects were tested on their own.  However when they were sat in a room all together they seemed to give the same answers as each other.  The result in this experiment is Conformity.

In 1951 a Social Psychologist called Solomon Asch invented an experiment to explore how pressure from one person could affect another person’s perceptions.  In total, one third of the subjects who were put in this situation went along with the clearly erroneous majority.  Asch’s experiment involved 4 lines, 3 of the lines were different lengths to the 1st line.  These were shown to college students in groups of 8 to 10.  He told them that he wanted to study the visual perception and that their task was to decide which of the lines matched the same as the 1st line.  It ...
