How to use this page

Everything here is a link to an external resource — open it in your browser, the same way you'd open a YouTube link. Nothing needs to be downloaded.

This week's load is deliberately light: 2 short readings + 2 short videos, grouped by the ideas from the lecture, plus one optional full-chapter reference. Read or watch one item per group and you're ready for the quiz; do all of them and you'll be very comfortable. Total time is roughly 40–50 minutes if you do everything, far less if you pick one per group.

Watching/reading order that matches the lecture: ① the sleep clock & the stages → ② why we dream → ③ how drugs alter consciousness.

A habit to start now: before you trust any claim about sleep, dreams, or drugs — in these resources or anywhere — ask the three questions from class: Which sleep stage or state is this about? Which way does a drug push the nervous system — slow, speed, or distort? What's the evidence, or is this just folklore?

A note on the drug topic. The drug resource below is accurate and non-sensational — it explains categories and concepts, not how-to. If this subject is personal for you or someone you care about, the campus counseling center is confidential and free to students; you can also reach out to Prof. Bennett.

① The Sleep Clock & the Stages

Maps to Lecture Segments 2–3. The circadian rhythm is your body's ~24-hour clock (suprachiasmatic nucleus, melatonin, light). A night of sleep cycles through NREM-1, NREM-2, NREM-3, and REM about every 90 minutes — and the brain stays busy the whole time.

Reading — "Stages of Sleep: Psychology, Cycle & Sequence" (Simply Psychology)
🔗 https://www.simplypsychology.org/sleep-stages.html
Why it's assigned: the cleanest plain-language walk through the sleep stages we drew on the board — NREM-1 to NREM-3 and REM, the ~90-minute cycle, sleep spindles and slow waves, and how REM lengthens across the night. Exactly Segment 3.
⏱ ~9 min

Video — "To Sleep, Perchance to Dream: Crash Course Psychology #9"
🔗 https://www.youtube.com/watch?v=rMHus-0wFSo
Why it earns the click: a lively ~10-minute tour of how we sleep — the stages, REM, sleep deprivation, sleep disorders, and a first pass at dreaming. It covers Segments 3–5 in one sitting. (Chapters in the description jump you straight to "Rapid Eye Movement," "4 Stages of Sleep," and "Why do we dream?")
⏱ ~10 min

② Why We Dream

Maps to Lecture Segment 5. Remember the three theories sit at different levels: Freud's hidden wish (manifest vs. latent), the brain weaving random REM activity (activation-synthesis), and the brain filing the day (information-processing).

Reading — "Sigmund Freud's Dream Theory" (Simply Psychology)
🔗 https://www.simplypsychology.org/sigmund-freud-dream-theory.html
Why it's assigned: the source of the manifest vs. latent content vocabulary we use in class, explained clearly, with Freud's "wish-fulfillment" idea laid out. Read it as the historical, psychodynamic theory — then weigh it against the biological and information-processing views from lecture (the reading is one theory, not the last word).
⏱ ~8 min

③ How Drugs Alter Consciousness

Maps to Lecture Segment 6. The whole topic gets simple when you sort drugs into three families by what they do to the nervous system: depressants slow it, stimulants speed it up, hallucinogens distort perception — plus the core ideas of tolerance, dependence, and withdrawal.

Video — "Altered States: Crash Course Psychology #10"
🔗 https://www.youtube.com/watch?v=9PW1fwKjo-Y
Why it earns the click: an accurate, matter-of-fact ~11-minute overview of how psychoactive depressants, stimulants, and hallucinogens act on the brain, plus tolerance and neuroadaptation — and a clear-eyed debunk of hypnosis myths (Segment 7). Non-sensational and concept-first, exactly the lens we use in class. (Description chapters jump to "Depressants," "Stimulants," and "Hallucinogens.")
⏱ ~11 min

Optional one-stop reference (free online text)

If you'd like one optional reference to skim all term, OpenStax Psychology 2e keeps its full text free to read online. Chapter 4 ("States of Consciousness") covers everything in this week — what consciousness is, sleep and why we sleep, the stages of sleep, sleep disorders, and substance use.
🔗 https://openstax.org/books/psychology-2e/pages/4-introduction
Why it's here: a reputable, currently-available reference you can return to in later weeks — entirely optional this week. (Its subsections 4.2–4.5 line up one-to-one with our Segments 2, 3, 6, and 7.)

Pick-one quick path (≈19 min total)

In a hurry? Do exactly these two and you'll be ready for the quiz:
1. Watch Crash Course Psychology #9 — To Sleep, Perchance to Dream (groups ① and a head start on ②).
2. Read Stages of Sleep (group ①) and skim the Altered States video's drug chapters (group ③).

Heads-up (links rot): these point to outside sites that occasionally move or rename pages. If a link ever fails, tell Prof. Bennett and use the OpenStax reference above in the meantime.
