Part 1 · 0:00–10:00

This part explains what the Introduction to Psychology course covers and how the course is run.

Key ideas

The course is a broad introduction to the human mind, covering topics like brains, children, language, memory, madness, disgust, and love. The professor says it is comprehensive, which means it covers a wide range of the subject. 3:40
You need to attend the lectures and do the readings, because the two overlap but are not the same. Some readings will not be covered in lectures, and some lectures will not connect to the readings. 4:29
Slides will be posted online, but looking at them does not replace going to class. If you miss a class, get notes from a classmate. 5:21
Grading includes a midterm and a final, a short book review near the end of the term, and weekly Monday questions. The Monday questions are marked pass or fail and are meant to keep you on track with the reading. 7:24
The professor gives clear advice for doing well: attend every class, keep up with the readings, and form a study group. He also suggests making contact with the teaching staff, though staying anonymous is allowed. 8:10

Words to know

comprehensive: covering a wide range of things, not just one small part of a subject.
teaching fellow: a helper who is assigned to a group of students, reads their Monday answers, and can answer questions.
subjects: the people who take part in a psychology experiment so researchers can study them.

Example

Think of a class like a sports team practice. Watching videos of the practice on your own helps a little, but it does not replace showing up and training with the team. The lectures are the practice, and the slides are the video.

Part 2 · 10:00–20:00

This part introduces the main areas of psychology and gives examples of big questions the course will cover, such as how the brain makes the mind, how children develop, why people differ, and what makes people good or bad.

Key ideas

Psychology can be useful in everyday life, such as in how you study, how you talk with people, and what kind of therapy might work for you. The course also aims to give a deep look at how the human mind works. 10:23
Psychology is often split into five sub-areas. Neuroscience studies the mind by looking at the brain. Cognitive psychology looks at how people think, understand language, and recognize objects, often using a computer as a comparison. 11:32
The mind depends on the physical brain. A person in a coma has no consciousness because of brain damage, which shows that thoughts, feelings, and free will rest on physical things. 13:26
Developmental psychologists ask how much of what we know is built in from birth and how much comes from culture, language, and schooling. People also differ from each other, and the course asks whether this comes from genes, upbringing, or both. 14:44
Morality is a central question. The course asks whether being good or bad is part of a person's nature or mostly due to the situation they are in. 19:37

Words to know

neuroscience: The study of the mind by looking at the brain and nerves.
cognitive: Having to do with thinking, such as how people understand language, remember things, and solve problems.
innate: Built in from birth, not learned. The lesson calls this hard-wired.
consciousness: Being awake and aware of yourself and the world around you.

Example

A newborn baby is born knowing how to suck milk, which is innate. Learning to speak a particular language, on the other hand, comes from the culture and people around the child. Developmental psychologists try to figure out which parts of what we know are like the milk-sucking and which are like learning a language.

Part 3 · 20:00–28:28

The professor explains why the course will study extreme and unusual mental disorders, and why looking at them helps us understand normal life.

Key ideas

The course will cover common disorders like depression and anxiety, plus rarer ones that teach us something about how the mind works. Many students in the room may be dealing with these disorders themselves. 20:43
Phineas Gage survived a metal pipe through his head, but his personality changed. He lost his sense of right and wrong and his self-control. This shows how damage to the brain can change a person's mind. 22:09
Capgras syndrome is a rare condition, usually caused by a stroke, where a person believes the people they love most have been replaced by impostors. Cotard's syndrome is a related condition where a person believes they are dead. 23:50
The professor says these extreme cases are not studied for shock value. They help us understand normal life, because extremes make everyday things easier to see clearly. 25:48
Cases like Capgras show that recognizing something (being able to name it) is different from knowing what it is. This teaches us how we see the world. 26:17

Words to know

Delusion: A strong false belief that a person holds firmly, even when the facts show it is not true.
Psychopathy: A condition where a person has little or no moral understanding, either from brain damage or from being born that way.
Amnesia: Memory loss, where a person forgets things, such as their past.
Stroke: A sudden problem where blood flow to part of the brain is blocked or broken, which can damage brain tissue.

Example

Think of a map that is missing one road. Looking at what happens when that road is blocked shows you how the whole map connects. In the same way, studying a brain condition that breaks one ability can show how that ability normally works.
