If your friend has suggested you see a psychologist or even become one yourself, you may be hesitant to take the advice because you're not really sure what psychologists do, how seeing one could help a person, or why you might want to become one. If you want to learn more about psychology and how it's used to help people, this article should be able to give you some of the basics.
Many people have the impression that psychologists are people who listen to people's problems and them prescribe them with medication to make them feel better, but this is a description of a psychiatrist, which is a type of medical doctor. Psychology is a branch of science not unconnected with medicine but focused more on the study of mental function and behavior. So a psychologist is more likely to study what makes people become an addict rather than helping them deal with the loss of their loved one with medication.
If, on the other hand, you are more interested in a fun career choice, you would do well to forego the psychology route and consider instead party and event planning. Find some great examples here.
Psychology is a scientific discipline that must be studied in university before you can make a career out of it. During your studies you will read, observe, and orchestrate many experiments to study the behavior of individuals and groups. Tests, decisions, situations, and puzzles may be presented to the subjects as a way of studying how their brains work and how the results of the test can be used to help predict or change their future behavior, which can help with the development of treatments for neural, social, and behavioral problems.
There are two ways in which psychology could become a career. If you're more interested in studying subjects and learning more about how the brain works and how people behave when they join a new company, you might like to become an academic psychologist. These types of people teach psychology to new students at university while also conducting studies and publishing the results in scholarly journals.
If you're more interested in how the things you learn from watching people in their own home can be used to help people who are struggling with neurobiological disorders, you might like to become an applied psychologist or psychotherapist. These psychologists use their knowledge to help people directly by applying the things they have learned toward developing treatment programs. Many psychotherapists work with experimental treatments based on the latest research from their academic colleagues.
