Introduction to Psychology

 

The term psychology derives from two Greek words: psyche, meaning "mind" or "soul," and logos, meaning "study." Thus, psychology can be understood as "the study of the mind or soul." These concepts of mind or soul are often regarded as the elements that distinguish living beings—animals and humans—from inanimate objects and plants.

Today, psychology is defined as the scientific study of behavior and mental processes. This field encompasses the examination of both animal and human behaviors. When focused on humans, psychology addresses all aspects of our thoughts, feelings, and actions. The issues surrounding behavior and mental processes are central to the human experience, as well as to that of animals. In our daily lives, we consistently display behavior, which refers to our actions and responses, whether they are conscious or unconscious. Additionally, we engage in various mental activities such as thinking, memorizing, understanding, and perceiving. Given the scope of psychology, it is evident that we encounter its principles in multiple aspects of our lives.

Psychologists investigate a wide array of concepts, including perception, cognition, attention, emotion, motivation, brain functioning, personality, behavior, and interpersonal relationships. A key area of interest in psychology is the unconscious mind. To explore these concepts, psychologists employ empirical methods to identify causal and correlational relationships among psychosocial variables.

Most psychologists work in diverse environments, including research laboratories, hospitals, and community settings, where they study the behaviors of both humans and animals. Some specialized topics within psychology include alcohol and drug addiction, memory, emotion, hypnosis, love, aggression, helpfulness, as well as the psychological aspects of politics, prejudice, culture, and religion. Additionally, psychologists practice in schools and businesses, using various research methods—such as observation, questionnaires, interviews, and laboratory studies—to deepen their understanding of behavior.
