Psychology can be defined as the study of mental processes and behavior. The term psychology comes from the Greek word psyche meaning "breath, spirit, soul" and the word logia meaning "study of."Psychology has not always existed as it has today. In fact, it is considered a relatively young discipline, although as one eminent psychologist explained, it has short past but a long history. Psychology emerged from biology and philosophy and is closely linked to other disciplines including sociology, medicine, linguistics, and anthropology.While psychology may be a young subject in the grand scheme of things, it has grown to play a tremendous role in the world today. Psychologists are employed in hospitals, mental health clinics, schools, colleges and universities, government agencies, private businesses, and private practice and perform a wide variety of tasks and roles ranging from treating mental illness to influencing public health policy.Psychology Relies on Scientific MethodsOne of the most common myths about psychology is that it is just "common sense." The problem with this is that psychological research has helped demonstrate that many of the things that we believe are just common sense are actually not true at all.

By challenging some of our misconceptions about how and why people behave as they do, psychologists are able to provide answers that help solve real-world problems.Unlike common sense, psychology relies on scientific methods to investigate questions and arrive at conclusions. It is through using empirical methods that researchers are able to discover relationships between different variables. Psychologists use a range of techniques to study the human mind and behavior, including naturalistic observation, experiments, case studies, and questionnaires.Psychologists Tackle Problems From Multiple PerspectivesTopics and questions in psychology can be looked at in a number of different ways. Let's take the topic of violence as an example. Some psychologists may look at how biological influences contribute to violence, while other psychologists might look at how factors such as culture, family relationships, social pressure, and situational variables influence violence. Some of the major perspectives in psychology include the:Biological perspectiveCognitive perspectiveBehavioral perspectiveEvolutionary perspectiveHumanistic perspectiveEach perspective helps contribute a new level of understanding to a topic.Imagine, for example, that psychologists are trying to understand the different factors that contribute to bullying. Some researchers might take a biological perspective and look at how genetics and the brain contribute to this type of behavior. Another psychologist might take a behavioral perspective and look at the different ways that such behaviors are reinforced by the environment. Other researchers might take a social perspective and analyze the impact that group pressure might have on bullying behaviors.No single perspective is "right." Each perspective contributes to how we understand a topic and allows researchers to analyze the myriad influences that contribute to certain actions and come up with multi-faceted solutions to combat problematic actions and encourage better outcomes and healthier behaviors.
