The study of human and animal mental functions and behavior is called Psychology. History records show this form of study originated from the days of China, Egypt, India, Greece and even Persia. From its infant and non methodological ways it has changed into a more precise and exact science today.

Psychologists are the people who have chosen to practice this social science of psychology as their profession. Interpersonal relationships, attention, motivation are some of the phenomena that psychologists try to solve. In short, psychologists are interested with how humans act and react towards others and circumstances.

One branch of psychology that has gained popularity is personality psychology. This type of psychology is very much available even to ordinary people in the form of personality tests that can be found in magazines, books and the internet. In essence, this area of psychology is interested in trying to understand the overall personality of individuals.

It is vital when starting with personality psychology that a logical study of the person’s personality has been conducted and analyzed. How the person’s results are the same or different from his peers or other similar subjects should then be checked. Detailed study would then be made on traits or reactions that will show up to be similar among different individuals.

An example of a personality psychology theory that has made huge waves in the scientific community is called Big 5. Agreeableness, conscientiousness, extroversion, openness and neuroticism are the five traits that make up the Big 5. The traits mentioned above can be observed in everyone although in different degrees for each individual.

Let us discuss each personality trait to be able to understand this fully. Very expressive, sociable, enthusiasms are seen from people who are said to be extroverts, and people who are willing to try out new things or are always seeking the latest happenings are said to have an open personality. Individuals who tend to conform or are easily swayed by what’s happening around them are said to have agreeable personality, while a person who gives close attention to detail is said to be conscientious.

Then there is neuroticism, the trait that is shown on people who are least capable of handling too much stress and who are always moody or anxious. By understanding these traits, we can now learn more about an individual’s personality and behavior. Still, further analysis and review of other psychology theories are made even when these five traits are easily visible in an individual.

It would be very easy to conclude that psychology can be found and applied in any field that humans are involved in. As human beings become more complex, psychology is now almost always present in every aspect of our lives as everyone has the interest to understand everybody. Job screenings and assessments of fitting individuals in organizations are just some practical uses of psychology.

As already discussed, it is a must that whenever human beings are involved, psychology should be present. For it is involved in better understanding the way the human mind functions. It is therefore advisable that psychology is present when seeking for individuals best fit in an organization or even in sports or in schools.
