university levels of education Psychology I — V
Five levels in one page, from Wundt's first laboratory to the replication crisis that reshaped the discipline — handmade, no ads, no sign-ups. One hundred topics and one thousand two hundred problems, every one of them carrying a full worked solution laid out step by step, a written lecture for every one of the hundred topics running to thirty-six thousand words, and ten ways to study the same material. Start at whichever level you need; it is all one file, and the last entry opens the whole subject at once.

Psychology I
Foundations, Methods, Biology and Perception. Where the discipline came from and how it establishes anything at all. The founding schools and what each thought psychology was for, the seven modern perspectives and how to tell which one a claim is pitched at, the figures who are usually left out of the list, and the working divisions of the field. Then research methods: which design answers which question and the one thing only an experiment can do, naming the parts of a study and spotting what has been left uncontrolled, sampling and the difference between reliability and validity, and the obligations owed to participants. Statistics follows, kept to what is actually needed — the measures of centre and spread and when each misleads, the normal curve and z-scores, the null hypothesis and what a p value does and does not say, correlation and effect size. Then the biology underneath: the neuron and the all-or-none signal, the transmitters and how a drug intervenes, the brain read off the deficit that follows damage, and the nervous and endocrine systems nested inside one another. It closes on sensation and perception, from absolute thresholds and Weber's law through the eye and the ear to Gestalt grouping, depth cues and the expectations that shape what you see. Twenty topics, 240 problems. Every topic is a full lecture: a summary, sections of explanation including how the questions are answered and where they go wrong, a table of key ideas, worked cases with the reason for every step, practice with hints, a quiz, defined terms, and three problems left unsolved for the reader — readable one lecture at a time or as one continuous scroll.

Psychology II
Consciousness, Learning, Memory and Cognition. The machinery of an individual mind at work. The architecture of a night's sleep and the circadian clock that governs it, the competing accounts of what dreams are, the four drug classes and the difference between needing more and being unable to stop, and what hypnosis can and cannot do. Then the two great conditioning traditions: labelling the four terms correctly, which is mostly a matter of order, generalisation and the extinction that turns out not to be unlearning, taste aversion and the preparedness findings that forced the theory to change, then the four operant contingencies and the two words that cause all the trouble, the schedules and the response pattern each produces, shaping a behaviour that does not yet exist, and the results that showed consequences are not the whole story. Memory next — the three-store model, the working memory that replaced it, why most study habits encode badly, the cues that decide whether you can retrieve, and the reconstructive processes behind both forgetting and confident false memory. It ends on thinking: algorithms against heuristics, the biases told apart by what each distorts, how children acquire language and what their errors reveal, and the long argument about intelligence and its tests. Twenty topics, 240 problems. Every topic is a full lecture: a summary, sections of explanation including how the questions are answered and where they go wrong, a table of key ideas, worked cases with the reason for every step, practice with hints, a quiz, defined terms, and three problems left unsolved for the reader — readable one lecture at a time or as one continuous scroll.

Psychology III
Development, Motivation, Emotion and Personality. How a person is assembled and what drives them. The three prenatal stages and why timing matters more than dose, what a newborn already arrives able to do, Piaget's four stages and the ages later work revised downward, Vygotsky's claim that development happens between people before it happens within them, and the specific maturation mismatch behind adolescent risk-taking. Then attachment, from Harlow's cloth mother to the four patterns and what they do and do not predict, parenting on two dimensions with the child's own temperament as part of the causal story, Erikson's eight conflicts across a life, and Kohlberg's levels read off the reasoning rather than the verdict. Motivation follows — five theories each fixing a problem in the one before, the signals that start and stop a meal and why the system defends against loss more strongly than gain, the beliefs that decide whether someone persists, and why reward sometimes destroys the interest it was meant to encourage. Then emotion and stress: whether the feeling comes before or after the bodily change, how badly we predict our own future feelings, Selye's three stages and the cost of running them too long, and what actually reduces the damage. It closes on four accounts of what personality is. Twenty topics, 240 problems. Every topic is a full lecture: a summary, sections of explanation including how the questions are answered and where they go wrong, a table of key ideas, worked cases with the reason for every step, practice with hints, a quiz, defined terms, and three problems left unsolved for the reader — readable one lecture at a time or as one continuous scroll.

Psychology IV
Social Psychology, Disorders and Treatment. The person among others, and what happens when things go wrong. Explaining other people's behaviour and getting it wrong in a predictable direction, Asch and Milgram with the conditions that actually move the figures, the two routes to changing a mind and what happens when action and attitude disagree, and what changes when someone acts as part of a group. Then prejudice and its three components with the conditions under which contact helps, where aggression comes from and the popular idea about it the evidence contradicts, what really predicts attraction and what sustains a relationship, and why people help or fail to. Disorder next: four criteria none of which is sufficient alone, the anxiety and trauma conditions told apart by what the fear attaches to, the mood disorders and the single distinction that changes treatment entirely, the somatic, dissociative and eating disorders, then the schizophrenia spectrum, the personality disorder clusters, the neurodevelopmental and neurocognitive conditions, and addiction as a disorder of the reward system. It ends on treatment — the insight therapies, the behavioural and cognitive ones, the drug classes with their costs stated, and why testimonials are worthless. Twenty topics, 240 problems. Every topic is a full lecture: a summary, sections of explanation including how the questions are answered and where they go wrong, a table of key ideas, worked cases with the reason for every step, practice with hints, a quiz, defined terms, and three problems left unsolved for the reader — readable one lecture at a time or as one continuous scroll.

Psychology V
Neuroscience, Psychometrics, Culture and Contemporary Issues. The advanced and applied end of the field. What each imaging method actually measures and why only lesion and stimulation work can establish that a region is necessary, how the brain reorganises and what the split-brain work showed, the attentional bottleneck and the prefrontal machinery managing it, and how a memory is physically made and why emotion makes it stick. Then the psychometrics behind any usable test — the three kinds of reliability with the arithmetic, the kinds of validity and how an instrument is actually built — and the statistics behind any defensible claim: choosing between t-tests, ANOVA and chi-square, reading the output, regression and factor analysis, and sizing a study properly. Then what inheritance contributes and what heritability actually means, what selection explains and the standing criticism of the framework, how much of the literature travels beyond WEIRD samples, and what the evidence supports about gender and sexuality. Psychology at work follows, in organisations, health and sport, education and the courts. It closes on the replication crisis and the reforms that followed, professional ethics, the critical perspectives, and where the field is going. Twenty topics, 240 problems. Every topic is a full lecture: a summary, sections of explanation including how the questions are answered and where they go wrong, a table of key ideas, worked cases with the reason for every step, practice with hints, a quiz, defined terms, and three problems left unsolved for the reader — readable one lecture at a time or as one continuous scroll.

The whole of Psychology
All five courses in one reader — one hundred lectures across twenty-five chapters, from Wundt's first laboratory to the replication crisis. Every lecture explains its topic in full: sections of prose, a section on how the questions are answered and another on where they go wrong, a table of the key ideas, three worked cases with the reason for every step spelled out, four practice questions with hints and answers, a three-question quiz, defined terms, and three problems left unsolved for the reader to do on their own. Where psychology turns quantitative — z-scores, correlation, effect size, power, reliability — the statistics are typeset as real mathematics. Nineteen ways to study the same material, from a plain reading mode and a continuous view that carries a whole course end to end in one scroll, to drills, quizzes, flashcards, key-idea sheets, a searchable index, progress tracking and print. Forty-six colour palettes, twelve layouts and custom colours throughout.
