Using Hergenhahns An Introduction To The History Of Psychology as a textbook
I used this book for an upper-level undergrad course, then again when I was TAing. It is the standard text most programs use. Hergenhahn covers the arc from ancient Greek natural philosophy through Wundt, the structuralist-functionalism split, behaviorism, psychoanalysis, and into the cognitive and modern eras. The second half focuses on applied developments and contemporary debates. It is not a dry encyclopedia. Hergenhahn tries to reconstruct the intellectual climate of each period, which means you get actual context for why certain ideas emerged when they did. The Wilhelm Wundt section is probably the most useful part of the whole thing. Most students walk away thinking Wundt invented psychology and nothing happened for fifty years. That chapter corrects that misconception fairly well by walking through his experimental work, his volitional psychology, and the institutional struggles he faced in Leipzig. The behaviorism chapters deserve more credit than they usually get. Skinner gets a lot of space, which some people complain about, but the contextual framing of why radical behaviorism appealed to people in mid-century America is necessary to understand how it took over experimental psychology departments. I remember one of my students arguing that behaviorism was just wrong and abandoned. The book shows it was absorbed rather than defeated, which is a subtler point that shows up on final exams.
What the book does poorly
Hergenhahn has a well-known bias toward the American experimental tradition. European contributions outside of Germany get short shrift. Piaget appears, but only in fragments scattered across chapters. The Gestalt psychologists are covered, but the treatment of their later influence on cognitive psychology feels rushed compared to the behaviorism sections. If your course needs more depth on continental or non-Anglophone psychology, you will need supplemental reading regardless of what edition you use. Another issue is the treatment of women in psychology. Mary Whiton Calkins shows up, but Margarete Bensel and other important early figures get mentioned in passing. This is partly a historical gap in the primary literature, but the book does not flag it explicitly. I usually assign supplementary readings on this because students come out of the course with a skewed sense of who was actually working in the field during the late nineteenth and early twentieth centuries.
How I get students through it
The book is dense. The chronological approach means readers carry forward a lot of names and dates without much repetition. My workaround was to have students build a timeline document as they read, adding not just dates but the key debate each period was responding to. By the time they reach the functionalism chapter, they see it as a reaction to structuralism rather than an isolated event. This takes about twenty minutes per chapter and cuts down on the end-of-term panic significantly. For the more obscure sections like pre-Socratic philosophy and its connection to psychological thought, I assign targeted passages rather than expecting cover-to-cover reading. The opening chapters on Plato and Aristotle are essential but easily skimmed. Students tend to either gloss over them completely or obsessively highlight everything, both of which miss the point. The relevant material is where Hergenhahn discusses teleology and the theory of forms as frameworks that psychology eventually had to move away from.

A specific edge case I ran into
When I was grading papers that relied exclusively on this text, I noticed a pattern. Students would attribute ideas to "the history of psychology" generally without distinguishing between different schools. One student wrote that behaviorists believed the mind could be studied directly, which is the exact opposite of what they believed. The book presents these schools sequentially, and without explicit comparison, students conflate them. I started requiring a two-column comparison chart for each major school, and the quality of the subsequent essays improved noticeably. It added maybe ten minutes of work per student but caught a lot of misunderstandings early. It is aimed at undergraduates, but graduate students in counseling or clinical programs often encounter it when they take a foundational course. The applied psychology sections are more relevant to those students. The chapters on the history of clinical psychology and psychotherapy give enough background to understand where current therapeutic modalities came from without getting bogged down in theoretical debates that belong in a separate course. If you are looking for a scholarly monograph on a single figure or movement, this is not it. It is a survey textbook. The breadth is its strength and its limitation. You get an overview, but you will need to go elsewhere for depth on any specific topic beyond the major figures like Wundt, James, Watson, and Skinner.
Downloading the material
The official route is through academic publishers and university bookstores. The latest edition is typically available through McGraw-Hill or its academic distribution partners. Some universities place course reserves for required textbooks. If you are taking the course, check whether your institution has an electronic copy through their library system before purchasing a physical copy. Many professors now build assignments around specific chapter readings, so having the exact edition matters less than having access to the text itself. Copies circulating on file-sharing platforms exist, but the copyright situation varies by edition and region. The eighth edition introduced substantial revisions from earlier versions, so if your syllabus references specific page numbers or sections, making sure you have the matching edition is worth the effort. Using an older edition for citation purposes can create mismatches that show up in grading.
