About Psy101
Psy101 is an independent reference project for people learning psychology and people deciding how to teach it.
Who can use Psy101
An instructor with a PhD in psychology may want an example that makes a difficult distinction clear, or a task that reveals how students understand it. An independent reader may want to investigate a claim encountered in everyday life. The guides support both learning and teaching, including school and university courses, adult education, online study and personal reading. Readers bring different experience to different topics; you can start with the question you have.
How to use the family
Use a definition, comparison, source note or teaching activity according to the task in front of you. When preparing a lesson, consider what an example would help learners distinguish and how you would check their understanding. When studying for yourself, try explaining an idea on a new example before returning to the guide. The site descriptions below help you choose a starting point; the links between guides let you follow a question further.
Textbook connections
OpenStax Psychology 2e provides the shared introductory textbook reference. Course connections point to relevant reading and distinguish direct coverage from contextual links where a guide extends beyond the textbook. Psy101 does not prescribe one syllabus. The material can accompany a course or support independent study; the textbook link does not establish every claim in a guide.

The family brings together selected guides to psychology's ideas, evidence, applications and history. It is not a complete glossary, a universal taxonomy or a global history. Many people, places and traditions are absent, and the historical selection leans toward European and North American research. Absence should not be read as a judgment of importance.
Reading source notes
A historical contribution, an interpretation of a film and a research finding require different kinds of support. Source notes identify the material consulted and the scope of inspection, such as a full text, selected passages, an abstract or an institutional account. For a claim you plan to teach or cite, follow the source and check the relevant passage. Keep an idea's historical influence separate from evidence for its explanation.
About the project
Psy101 is a project by Jacob Ceki Hazan. AI tools have assisted drafting and editing; that assistance does not itself verify a claim. The material is educational, not clinical advice, and offers no diagnostic tools. The sites use no analytics. Reading preferences such as text size stay in your browser. This page was updated in October 2026.
Basics
Basics: Basics is a visual starting point for readers new to psychology. Short guides explain a useful distinction, illustrate it with an original scenario and offer a question with an explanation. Illustrated trees introduce selected contributors and fields, with readable text companions and source links.
Fields
Fields: Fields compares psychology's research areas, interdisciplinary fields, professional specialties and methodological traditions. Start with the directory, or switch to History. Profiles connect questions, methods and documented contributors with official university examples, professional settings and sources.
People
People: People holds profiles of psychologists, earlier thinkers and people from neighboring fields. A profile explains why the person matters, what they contributed, the context of their work and the sources behind the account. Browse the chronology or use the alphabetical directory.
Timeline
Timeline: Timeline is a chronology of historically dated events: publications, experiments and institutional milestones. Each entry has a date, an account, context and sources. Publication years, experiment dates and institutional milestones are distinguished.
Popular Psychology
Popular Psychology: Popular Psychology follows psychology into self-help, advertising, consumer choices and digital platforms. Its Directory starts with topics, experiments and company cases; an optional Timeline puts the same records in date order. Evidence labels distinguish company accounts, independent research, interpretations and unsupported claims.
Films
Films: Films connects films, TV series and documentaries with psychology concepts and questions. Browse by topic or follow release dates in the timeline. Profiles distinguish interpretations of a story from scientific evidence, with source notes and clearly labeled companion readings.
Literature
Literature: Literature connects literary works with psychology topics and questions. Profiles distinguish interpretations of a text from scientific evidence and identify the sources and companion readings behind those connections.
Concepts
Concepts: Concepts is an alphabetical reference to foundational psychology terms. Each profile connects a definition with an original teaching scenario, a common confusion, limitations and inspected sources. Paired comparisons and understanding exercises help distinguish neighboring concepts. Textbook links identify direct coverage or contextual reading.
Theories
Theories: Theories examines explanatory accounts across psychology. Profiles distinguish a theory, model or broader framework, explain what it predicts and connect it with research and limitations. Contributors and historical context are kept separate from evidence that an explanation is correct.
Methods
Methods: Methods follows the construction of psychological evidence through research designs, measurement, analysis, ethics and reproducibility. Profiles explain procedures and inference limits. Interactive examples use labeled teaching scenarios or generated data rather than presenting demonstrations as empirical findings.
Experiments
Experiments: Experiments examines selected studies and research paradigms through questions, designs, findings and inference limits. Profiles distinguish primary research from textbook context, explain ethical concerns and discuss replication or reassessment. Original teaching questions help readers reason about what a study can support.
Measures
Measures: Measures describes 22 selected psychological instruments and task families. Profiles explain constructs, procedures, scoring logic, developers, evidence and limitations. A reading guide and original synthetic score examples help interpret measurement without administering clinical tests or collecting health answers.
Debates
Debates: Debates organizes disputed questions around the claims being evaluated and the evidence that bears on them. Profiles distinguish empirical disagreement from conceptual or value questions, identify shared ground and explain what remains uncertain. Different positions are not assumed to have equal evidential support.
Teaching
Teaching: Teaching is a reference for introductory psychology educators. It connects teaching history and research with course goals, assessment, teaching formats, books and websites. Curriculum comparisons distinguish college, AP and IB contexts and the limits of applying evidence across settings.
Artificial Intelligence in Psychology Education
Artificial Intelligence in Psychology Education: AI examines generative and agentic systems through teaching, learning and assessment in psychology. Human perspectives, research, debates and dated developments connect technical changes to educational decisions. Product claims and independent evidence remain distinct.
