Abstract

One of the first studies of social influence was performed in 1898, when Norman Triplett showed how children who were asked to turn a fishing reels as fast as they could would spin the wheel faster if there were other children in the room. This effect was actually called social facilitation, as it seemed that the task was made easier, or facilitated, by the presence of others.

The aim of this experiment was to discover if this statement is true. The experiment was conducted using eighteen first grade students, 10 girls and 8 boys, where the average age was seven years. The participants were brought into a familiar classroom where they were expected to solve a Chinese puzzle. The same groups of children were exposed to two different conditions, where they in the first case worked alone when they solved the first puzzle, and in the second case they worked in pairs without collaboration, solving the second puzzle. The aims stated that an improvement in performance could be produced by the mere presence of conspecifics. The results obtained from the experiment show the opposite of what was expected; participants took longer in the together group than they did alone.

Introduction

There is evidence that individuals do work better and more efficiently in group settings than when they are alone. The mere presence of other people may enhance performance, even when those people are not working together on the task.

One of the first experiments on this theory, was conducted by Norman Triplett (1898), when he once discovered that cyclists attain higher speeds when they are being paced or racing in competition with other cyclists than when racing alone. Triplett believed that the presence of another rider was a stimulus to the racer in arousing the competitive instinct, and thereby releasing or freeing nervous energy, that he cannot do for himself.

In order to test these effects, Triplett designed a laboratory experiment where he used two fishing reels arranged side by side, where the participant’s task was simply to reel string as fast as possible. Forty children were tested under two performance conditions, working alone or working in competitive pairs.  About half of the participants in the experiment performed better, where they reeled faster, when they were in-group situation than when they were alone.  Of the other half, some performed the same in both settings, while others actually performed worse when they were paired with others.

Social facilitation refers to the finding that individuals perform better in the presence of others than when working alone, but as a contrast other studies found evidence of social inhibition, which actually is the case in this experiment. Social inhibition is one of the social facilitation effects, where the performers do worse in the presence of others. In some other cases participants did better when performing in the company of others under some conditions, but did worse under other conditions.
