Understanding human behavior is not an easy task, but these psychological effects can help you to understand human behavior.

If you want to understand the psychology of our behavior, or want to increase your knowledge about human psychology, then this article is for you.

These psychological effects can refer roughly to all basic human actions, including behaviors that have no logic.

All these psychological effects have been observed and proven by researchers.

So let’s see some amazing psychological effects of human behavior.

1. Social Facilitation Effect

Researchers have seen improvements in individual performance when working with others (who are performing similar tasks) rather than alone.

And this phenomenon is known as the social facilitation effect.

According to this psychological effect, a person’s performance will be increased when he is working with other individuals who are performing similar tasks (especially in an organization or office).

The social facility was first identified by Norman Triple in 1898, when he observed that the performance of a cyclist was facilitated (helped) during training as a group.

You can use this psychological effect to increase your productivity. Now let’s move on to our next effect from the list of 18 psychological effects.

2. Birthday Number Effect

The birthday-number effect is a subconscious tendency of humans, where people prefer their date of birth numbers (compared to other numbers).

Most people like themselves, and birthday is associated with themselves, and therefore birthday numbers are liked by many.

Those who do not like themselves do not demonstrate the birthday number effect.

The birthday number effect was first reported in 1997 by Japanese psychologists Mayumi Karasawa and Shinobu Kitayama.

3. Bystander Effect

The bystander effect states that the more people present, the less likely it is that one person helps another person in a crisis.

This happens because being a part of a large crowd, a person does not have to take responsibility for action.

In a 1969 experiment, Rodin and Latane found that about 70% of people helped a woman in distress when they were the only witness.

But when there were others, only about 40% had helped.

So make sure to ask for help from any person alone and not in a group. Now, let’s move to our next effect from the list of 18 psychological effects.

4. Cheerleader Effect

According to Cheerleader Effect, an individual seems to be more attractive in group pictures compared to a single.

This means that when photos have many people it makes a person more attractive.

This effect name is cheerleader effect because cheerleader looks more attractive when she is with her team than alone.

And similarly, individuals in a group seem more attractive than singles.

Use this effect to look more attractive in pictures. Now let’s move on to our next effect from the list of 18 psychological effects.

5. Cocktail Party Effect

The cocktail party effect refers to the ability of people to focus on one thing in a noisy environment.

This means that people can listen to another person in a noisy environment and do not notice the noise until they focus on it.

It was first described by a British scientist Colin Cherry, in the 1950s.

An example of this effect:- If you are talking to your girlfriend at a noisy party, you can understand and hear her voice, but ignore what other people around are saying.

In evolution, our brain developed the ability to filter out the noise so that we can get the most accurate and relevant information from our surroundings which was necessary to survive ourselves from animals.

6. Einstellung Effect

According to the Einstellung effect, humans have a tendency to use the old solution (already used solution) for any problem, even if we have a more effective solution for any problem.

Our brain tries to work efficiently by using old solutions for the same problem because it saves a lot of energy and time.

By using old solutions for the same problem, we save energy and time, but by this, we do not do anything new.

A study taken by researchers, where participants have to solve a series of water jar problems.

After solving many water jar series, participants use the same solutions for solving other water jar series even though easier solutions existed.

Now let’s move on to our next effect from the list of 18 psychological effects.

7. Generation Effect

The generation effect is a psychological effect, where information is remembered better if it is generated by our own mind as compared to reading the information.

A person is more likely to retain information when asked to generate an answer with their own mind, compared to having that same information provided.

For example:- Students are more likely to remember an answer if it is produced by themselves as compared to provided answers by teachers.

This effect is very useful for teachers and parents to help their children, just explain everything to them about any chapter and ask them to answer the questions.

8. Golem Effect

The Golem effect is a psychological phenomenon in which a person’s performance can be increased or decreased by their leader’s expectations.

If a leader has high expectations from a person, then the performance of a person will increase but if the expectations of the leader are low, then a person’s performance will decrease.

For example:- In-office employee performance will be increased if his manager has higher expectations with him, but if his manager has lower expectations then his performance will be decreased.

Use this psychological effect to improve one’s performance. Now let’s move on to our next technique from the list of 18 psychological effects.

9. Google Effect

The Google effect is the tendency of people to forget information that can be easily found using Internet search engines (eg: — google and yahoo).

This psychological effect was first explained in 2011 by Betsy Sparrow and Jenny Liu and Daniel M. Wegner.

According to the study, people are more likely to forget the information if they believe that they can easily get that information with the Internet.

This study also suggests that your memory power will not be affected by this.

My main purpose of covering this psychological effect is to convince you that reading from books is more beneficial for you.

10. Halo Effect
