Psychology is the science that academic and appliedly investigates human behavior and cognition. It is a fundamental branch of social sciences concerned with studying the mind and personality, seeking solutions for mental illnesses and understanding human activity across various fields.

Etymology and Definition of Psychology

The term originates from Greek, consisting of two parts: the first refers to "Soul or Life," and the second means "Science or Systematic Research." Definitions have evolved across different schools of thought:

• Psychoanalysts: Focused on conscious and unconscious mental life.
• Behaviorists: Defined it as the science that studies observable behavior.
• Integrative Definition: The science that links the mind, behavior, and both conscious and unconscious human experience.

The Origins and Evolution of Psychology

Modern psychology began when Wilhelm Wundt established the Structuralist school, which relied on "Introspection"—a method where individuals describe their own mental processes. Later, other scientists criticized this for being too subjective, leading to more objective scientific schools.

Core Goals of Psychology

Psychology strives to achieve four main objectives that contribute to the development of individuals and society:

1. Understanding and Interpretation: Reaching a conscious understanding of the causes behind human behavior.
2. Prediction: Anticipating how an individual will behave in the future based on current data.
3. Control and Regulation: Setting rules to manage behavior and guide it toward a positive path.

Main Fields and Branches of Psychology

This science is divided into several theoretical and applied branches, most notably:

• Experimental Psychology: Studies cognitive processes (hearing, vision, thinking).
• Physiological Psychology: Investigates the relationship between behavior and biological processes in the body.
• Social Psychology: Examines how groups influence individual behavior and vice versa.
• Educational Psychology: Concerned with academic achievement and the learning process.
