Social Enhancement Theory is a psychological theory that explains how individuals are influenced by the presence of others in their environment. This theory suggests that the mere presence of other people can enhance an individual’s performance on a task.

What is Social Enhancement Theory?

Social Enhancement Theory is a concept that originated from the field of social psychology. It suggests that when people are performing a task in the presence of others, their performance tends to improve. This improvement in performance is known as the social enhancement effect.

The social enhancement effect occurs because of increased arousal and motivation levels in individuals when they are observed by others. The presence of an audience can make individuals more alert and focused on the task at hand, leading to better performance.

History of Social Enhancement Theory

The concept of social enhancement has been studied for decades, with early research taking place in the 1800s. However, it was not until the mid-20th century that researchers began to investigate this phenomenon systematically.

One early study conducted by Triplett in 1898 observed that cyclists tended to perform better when racing against other cyclists compared to racing alone against time. This study provided an early indication that the presence of others could enhance one’s performance.

Since then, numerous studies have been conducted on social enhancement theory, exploring different aspects like group dynamics and competition.

Types of Social Enhancement

There are two types of social enhancement: coaction and audience effects.

Coaction effect refers to improved performance due to working alongside other people who are performing similar tasks, while audience effect refers to improved performance due to being observed by others.

Factors Affecting Social Enhancement

Several factors can affect social enhancement, including the size of the group, the task being performed, and the level of competition among individuals.

The size of the group can influence social enhancement. The effect tends to be stronger with larger groups than smaller ones.

Additionally, the type of task being performed also plays a role. Tasks that require physical strength or endurance tend to show more social enhancement effects than those that require mental concentration.

The level of competition among individuals also plays a crucial role in social enhancement. Studies have shown that when individuals are competing against one another, the social enhancement effect tends to be stronger.


In conclusion, Social Enhancement Theory suggests that individuals tend to perform better when they are observed by others or working alongside them. This theory has been studied for decades and has provided valuable insights into how group dynamics can influence human behavior.

By understanding the factors that affect social enhancement, we can use this knowledge to improve individual and group performances in various settings.
