Evolution of Psychology’s Definition

Initially focused on studying consciousness, then human behavior, and later the unconscious. Subsequently, it shifted to mental phenomena. Currently, psychology is considered a science that deals with humans as a function of personality within a social and cultural context.

Scientific Psychology

In 1879, Wilhelm Wundt created the first experimental psychology laboratory, marking the birth of scientific psychology. His aim was to study the structure of human consciousness using self-observation. According to his theory, consciousness is formed by elements linked by associative links. To study psychic life, he decomposed it into its simplest elements and then reassembled them.

Psychology’s Greek Definition

Aristotle emphasized the unity between body and soul. Psychology studies the human soul. At the end of the 19th century, psychology separated from philosophy and became an autonomous discipline. It’s considered that psychology was born as an independent discipline in 1879 with Wundt’s founding of the first experimental psychology laboratory.

Current Definition of Psychology

Psychology is the science that studies human actions. Its goal is to study behaviors, particularly tutoring, attention, language, motivation, reasoning, thinking, effective life, personality, interpersonal relationships, frustrations and disorders, groups, and the influence of society and culture on human development.

Psychology originated in ancient Greek and Latin philosophical concerns about the human soul’s nature. It became an autonomous discipline in the late 19th century. Psychology distinguishes different objects of study based on research programs and methods represented by different schools. Behaviorist psychology focuses on behavior. Psychoanalytic psychology focuses on the unconscious. Cognitive psychology focuses on mental processes.
