History of Psychology: From Freud to Psychopharmacology
This paper surveys the historical development of psychology from its early biological explanations of human behavior, through Sigmund Freud's psychoanalytic framework, and into the neo-Freudian contributions of theorists such as Karen Horney, Erik Erikson, and Carl Jung. It examines how Freudian concepts — including the unconscious, dream analysis, and repression — shaped clinical practice, and how later theorists shifted focus toward the individual within society and across the full lifespan. The paper concludes by noting psychology's return to a biological emphasis in the 21st century, driven by the rise of psychopharmacology, and reflects on how this shift has reduced the centrality of talk therapy and family or social context in modern psychiatric treatment.

What makes this paper effective
- Uses a clear chronological framework that traces psychology from 19th-century biological determinism through psychoanalysis, neo-Freudian theory, and into 21st-century pharmacology, giving readers an accessible historical throughline.
- Identifies a meaningful "full circle" pattern — beginning and ending with biological explanations — which provides a unifying argumentative thread across the survey.
- Briefly contrasts the methodological standards of Freud's era with modern scientific demands, grounding historical summary in critical reflection on research rigor.
Key academic technique demonstrated
The paper employs comparative historical synthesis: rather than treating each theorist in isolation, it places figures like Freud, Jung, Horney, and Erikson in dialogue, noting where later thinkers extended, modified, or departed from earlier frameworks. This technique allows a short essay to cover broad intellectual history without sacrificing analytical coherence.
Structure breakdown
The paper opens with a thesis framing psychology's historical arc as a "full circle." It then examines Freudian psychoanalysis, moves to neo-Freudian and developmental theorists, pivots to Jung's synthesis of old and new ideas about personality, and closes with the rise of psychopharmacology as a return to biological causation. The conclusion is embedded in the final paragraph rather than set apart as a separate section.
Introduction: Psychology's Historical Arc
In many ways, the history of psychology can be said to have come full circle — from its early attribution of human behavior to purely biological causes, to psychoanalysis' emphasis on the mind's ability to influence the body, to today's modern use of psychopharmacology, which employs chemicals to modify human behavior. However, the modern practice of psychology is more often grounded in scientific evidence rather than anecdote. The 19th-century theorist Sigmund Freud developed his theory of human psychological development from a handful of case studies — a methodology that would not satisfy today's more rigorous demands for scientific objectivity and the quantification of treatment outcomes (Myers, p. 46).
Freudian Psychoanalysis and the Unconscious
In Freud's day, psychology did aspire to some form of scientific validity. Physicians tended to view the human mind as affected by biological complaints — such as a "wandering womb" thought to produce hysteria in women. Freud, however, believed that human behavior could be explained by probing the inner psyche, or unconscious, through the analysis of dreams, slips of the tongue, and patient resistance to certain ideas (Myers, p. 568). Psychoanalysis, the therapeutic approach Freud developed, sought to give clients insight by bringing them to a state of conscious awareness, achieved by interpreting previously repressed feelings (Myers, p. 568).
Neo-Freudian Theorists and Human Development
Later theorists were more inclined to focus on the individual within society, and to analyze the human person not in a pathological or arrested state, but in a normal one. The contributions of theorists such as Karen Horney and Erik Erikson during the early part of the 20th century emphasized human development from infancy through adulthood, as well as the evolution of human society from a more collective or "primitive" state toward today's individualistic culture.
