Week 8 — Lecture Outline · Midterm Review & Exam

Introduction to Psychology · PSYC 1 Fall 2026 · Prof. Bennett Fictional sample

Course: Introduction to Psychology (PSYC 1) · Silver Oak University (fictional sample) · Prof. Bennett
Objectives covered: cumulative — Objectives 1–5 (Weeks 1–7). Obj 1 — the science of psychology & its perspectives; Obj 2 — research methods & ethics; Obj 3 — biological bases of behavior; Obj 4 — sensation, perception & consciousness; Obj 5 — learning & memory.
SLOs touched: A (apply concepts to real-world behavior) · B (reason scientifically about claims regarding mind and behavior)
Meeting pattern: 2 sessions × 75 min = 150 min. Segment minutes below total ~150; scale to your own pattern.

This is a review-and-exam week — no new content. Each segment briskly re-teaches one objective from Weeks 1–7 with its highest-yield ideas, one signature example, and the single misconception most likely to cost points, then the final segment frames the midterm itself. Built to be taught from cold as a review: an instructor (or a substitute) can run it without having taught the first seven weeks, because every definition and cure travels with the segment. The midterm covers Objectives 1–5; it does not reach the cognition/intelligence and later material that begins in Week 9.

Week at a Glance


The week's big question	"Across the whole first half — what psychology is, how it studies behavior, the brain behind it, how we sense and become aware, and how we learn and remember — what is the one honest move each topic asks of us, and where does everyone slip?"
By the end of the week, students can…	(1) re-derive each objective's core move on demand — define psychology and read a behavior through the right perspective (Obj 1); name a study's design, IV/DV, and whether it earns the word cause (Obj 2); trace the neuron and match a brain structure to its job (Obj 3); tell sensation from perception and recognize a sleep stage or a drug class (Obj 4); label a conditioning scenario and explain the memory model and why memory is reconstructive (Obj 5); (2) name and avoid the highest-cost misconception in each objective; (3) walk into the Midterm knowing its format, its weight (20%), and a concrete preparation plan built around the Study Guide, the Exam-Prep Tutorial, and the Practice Exam.

Segment 1 — Hook & the Map of the First Half (8 min) · Session 1 opens

Hook. Put one sentence on the board with no comment: "We only use 10% of our brains." Ask: "True or false — and how do you know?" Let the room split, then point out they're reaching for exactly the move the whole first half taught: don't trust what feels obvious; ask what the evidence shows. (It's false — imaging shows activity across virtually the whole brain.)
- "That instinct — to interrogate a claim about people before believing it — is the entire first half of this course. Today we walk the whole arc once, fast, and find the exact spot in each topic where points get lost."

The promise (write it on the board): "By Thursday you'll be able to take any of the five big areas — what psychology is, how it studies behavior, the brain, sensation & awareness, and learning & memory — and on demand state the one honest move it requires and the one mistake that sinks it. That's the midterm."

The map (one slide, say it out loud — this is the photograph slide of the week):

Obj 1 — WHAT psychology is (behavior + mental processes; six perspectives; it's a science). Obj 2 — HOW we study it (descriptive / correlational / experiment; correlation ≠ cause). Obj 3 — the BRAIN behind it (neuron, neurotransmitters, structures). Obj 4 — SENSING & being AWARE (sensation vs. perception; sleep & consciousness; drugs). Obj 5 — LEARNING & MEMORY (classical/operant/observational; how memory works and fails).

Why it matters line (memory hook): "Weeks 1–7 are one sentence: psychology studies behavior and mental processes scientifically — by testing claims, mapping the brain, tracing how we sense and become aware, and explaining how we learn and remember."

Segment 2 — Objective 1 Review: What Psychology Is, and Its Lenses (16 min)

Re-teach in plain language. Psychology is the scientific study of behavior and mental processes. Behavior is what we can see and record; mental processes are the internal events we infer ("behavior we see; mental processes we infer"). What makes it a science isn't its topics — it's the scientific attitude (curious, skeptical, humble) and empiricism (evidence over "it's obvious"). Hindsight bias is why untested claims feel certain. And working psychologists read any behavior through six perspectives — biological, psychodynamic, behavioral, cognitive, humanistic, sociocultural — grouped as bio-psycho-social; they're complementary, not rivals.

One worked example (do every lens briefly):

Behavior: a student feels intense anxiety before a presentation.
- Biological: the amygdala fires; adrenaline spikes heart rate. Cognitive: "I'll freeze, everyone will laugh." Behavioral: a past speech that bombed made public speaking a learned fear cue. Humanistic: a gap from the poised "ideal self." Sociocultural: a culture that prizes "saving face" raises the stakes. Psychodynamic: an unconscious fear of being judged.
- The point: "which lens is correct?" is the wrong question — "what does each reveal?" is the right one.

Highest-cost misconception + cure:
- ❌ "The perspectives are rivals — one is right and the rest are wrong," and "Freud (or Wundt) founded each early school."
✅ Cure: they operate at different levels of analysis — saying anxiety is "just brain chemistry" is like saying a novel is "just ink." And get the history right: Wundt, 1879 founded scientific psychology; structuralism named the parts (Wundt/Titchener), functionalism asked the purpose (James). Theory = a well-supported explanation that makes testable predictions; the single prediction is a hypothesis — "it's just a theory" is everyday language, not science.

Segment 3 — Objective 2 Review: How We Know — Methods & the One Big Mistake (22 min)

Re-teach in plain language. Three kinds of study, three different rights to the word cause: descriptive = watch and report; correlational = measure two things and see if they move together (a link); experiment = manipulate one variable (the IV) and measure another (the DV) while controlling the rest — the only design that earns cause. "Describe = watch · Correlate = measure a link · Experiment = manipulate and compare." The most expensive mistake in all of research lives here: correlation ≠ causation, because of the third-variable problem (something unmeasured drives both) and the directionality problem (which way does the arrow point?). And two "random" tools do different jobs: random sampling = who's studied (so results generalize); random assignment = who's treated (so a difference can be caused by the IV).

One worked example (read it, reason it out):

Headline: "Students who use a study app get higher grades."
- As a survey, this is correlational — a link, not proof. A likely third variable: more motivated students self-select into the app, and motivation could raise both app use and grades.
- To earn cause, run an experiment: randomly assign 200 students — half use the app, half don't — for a month, then compare grades. IV = app use; DV = grade. Random assignment balances motivation across the groups.
- Honest report (SLO B): "App use and grades rise together here, but only the randomized version could say the app causes it."

Highest-cost misconception + cure:
- ❌ "A strong correlation proves X causes Y," and "random sampling and random assignment are the same thing."
✅ Cure: ask "was anything randomly assigned?" — if no, it's a link; hunt the third variable. And keep the two randoms straight: sampling → generalize; assignment → cause. (Bonus trap: strength is the absolute value — −0.85 is stronger than +0.30.) "Correlation is a handshake, not a push."

Segment 4 — Objective 3 Review: The Brain Behind the Behavior + Quick Drill (14 min) · Session 1 closes (~75)

Re-teach in plain language. Behavior runs on biology. One neuron receives at the dendrites, decides at the soma, fires an all-or-none action potential down the axon (sped by myelin), and releases neurotransmitters at the terminals — which cross the synaptic gap to the next cell. "Neurons never touch — they text." Neurotransmitters each have a role (dopamine = reward/movement; serotonin = mood/sleep; GABA = the brakes; glutamate = the gas). Zoom out: CNS (brain + cord) vs. PNS; within the autonomic PNS, sympathetic = gas (fight-or-flight) and parasympathetic = brake (rest-and-digest). And match structures to jobs: hippocampus forms memories, amygdala = fear, cerebellum = coordination, and the lobes — front plans, parietal feels, occipital sees, temporal hears.

Interaction — rapid-fire "name the structure / branch" (think-pair-share, ~8 min):
Put four one-line scenarios on a slide; students name the structure or division, solo (30 s), neighbor (1 min), then call it out.

After a near-miss in traffic, the heart slows and digestion resumes. (parasympathetic — rest-and-digest)

A person can't form any new long-term memories after damage to one structure. (hippocampus)

A region at the very back of the brain is active while reading these words. (occipital lobe — vision)

A stronger pinch doesn't make a "bigger" nerve signal, just more frequent firing. (the all-or-none principle)

Debrief the all-or-none one (#4): the trap is imagining a "bigger" action potential — intensity is coded by rate, not size.

Highest-cost misconception + cure:
- ❌ "We only use 10% of our brains," and "neurons touch to pass the signal."
✅ Cure: imaging shows activity across virtually the whole brain; there's no spare 90%. And the signal is electrical inside a neuron but chemical across the gap — there's a synapse. (Bonus: a neurotransmitter is associated with a state, not a simple on/off "cause.")

Segment 5 — Objective 4 Review: Sensing the World & States of Awareness (20 min) · Session 2 opens

Hook back in: "Session 1 we built the brain. Now: what it does with the world coming in — and what happens to awareness when we sleep or alter it."

Re-teach in plain language. Sensation = detecting physical energy; perception = organizing and interpreting it; transduction = converting energy into neural signals — the bridge between them. "Detect it · translate it · interpret it." Perception runs bottom-up (raw data pushing in) and top-down (knowledge reaching out) at once. Thresholds: the absolute threshold is the faintest stimulus detectable 50% of the time; the difference threshold (JND) is the smallest change you can notice (a constant proportion, by Weber's law); sensory adaptation dials down a constant stimulus (the bakery smell fades). In vision, rods see dim light and the periphery in black-and-white; cones see color and detail in good light ("cones for color"). The brain groups input by Gestalt principles and judges distance with depth cues. Then consciousness: a ~24-hour circadian rhythm (run by the SCN) drives a ~90-minute sleep cycle through NREM-1 → 2 → 3 → REM, where REM brings vivid dreams and "paradoxical" active-brain/still-body sleep. Drugs are depressants (slow you — alcohol), stimulants (speed you — caffeine), or hallucinogens (distort), and repeated use brings tolerance, dependence, and withdrawal.

One worked example (do it out loud):

Scenario: you hear your name across a noisy party.
- Sensation: sound waves hit the ear. Transduction: the ear converts them to neural signals. Perception: the brain organizes and interprets them as your name — and top-down expectation (you're listening for it) makes you catch it over the noise.
- Tie-in: after a few minutes you stop noticing the party's background hum — sensory adaptation to a constant stimulus.

Highest-cost misconception + cure:
- ❌ "Rods let us see color," and "the brain shuts off when we sleep," and "alcohol is a stimulant."
✅ Cure: it's cones for color (rods = dim light, black-and-white). The sleeping brain is intensely active, especially in REM — "asleep is not unplugged." And alcohol is a depressant; the early "buzz" is lowered inhibition, not stimulation.

Segment 6 — Objective 5 Review (Part 1): How We Learn (20 min)

Re-teach in plain language. Learning = a relatively permanent change from experience. Three models:
- Classical conditioning (Pavlov) — an association between two stimuli. Label the four parts: UCS (automatic trigger) → UCR (automatic reaction); a neutral stimulus paired with the UCS becomes the CS, producing a learned CR. "Unconditioned = unlearned; conditioned = learned; the CR is the UCR's learned echo."
- Operant conditioning (Skinner) — behavior shaped by consequences. The rule that prevents every mistake: reinforcement always INCREASES behavior; punishment always DECREASES it. Positive = ADD; negative = REMOVE — add/remove, not good/bad. Schedules matter — variable-ratio (the slot-machine schedule) produces the steadiest, hardest-to-quit behavior.
- Observational learning (Bandura's Bobo doll) — we learn by watching a model, no direct reward needed; vicarious reinforcement (seeing the model rewarded) makes imitation more likely.

One worked example (label every part):

Scenario: a person tenses up at the smell and sound of the dentist's office before any tooth is touched.
- UCS = the drill (causes pain automatically). UCR = pain/tensing to the drill. Neutral → CS = the office smell/sound (paired with the drill over visits). CR = the anxiety felt walking in.
- Tie-in: many cleaning-only visits with no drill would let the anxiety fade — extinction.

Highest-cost misconception + cure:
- ❌ "Negative reinforcement is just punishment," and "positive/negative means good/bad."
✅ Cure: negative reinforcement INCREASES behavior — it removes something aversive so the behavior happens more (buckle up → the beeping stops → you buckle faster). Read positive/negative as add/remove, not as value. Did the behavior go UP or DOWN? decides reinforcement vs. punishment. (And classical = reflexive response to a signal; operant = voluntary behavior shaped by consequences.)

Segment 7 — Objective 5 Review (Part 2): How Memory Works — and Fails (22 min)

Re-teach in plain language. Memory is three processes — encoding (get it in), storage (keep it), retrieval (get it back) — across three stores: sensory memory (a split-second echo) → short-term / working memory (~20–30 seconds, about 7±2 items — "short-term holds; working memory works") → long-term memory (vast, durable). What makes things stick is elaborative rehearsal (connecting to meaning), not plain repetition, and chunking beats the 7±2 limit. Long-term memory splits into explicit (knowing THAT — facts and events you can declare) and implicit (knowing HOW — skills and conditioned responses). The headline of the week: memory is reconstructive — you rebuild it each time from fragments, not replay a recording — so the misinformation effect can edit it.

One worked example (the signature study):

Loftus & Palmer's car-crash study. People watched the same accident film, then were asked how fast the cars were going — but the verb was changed. "Smashed into" produced higher speed estimates than "hit." A week later, the "smashed" group was more likely to falsely remember broken glass — there was none.
- The read: a single word rewrote the memory; the people were sincere and confident, and still wrong. "Confidence ≠ accuracy."

Highest-cost misconception + cure:
- ❌ "Memory is a video recording we play back," and "if a memory feels vivid and I'm confident, it must be accurate."
✅ Cure: memory is reconstructive and editable — vivid "flashbulb" memories drift over years while confidence holds. A confident eyewitness can be flat wrong, especially after a leading question. "Memory isn't a recording — it's a story you rebuild."

Segment 8 — The Midterm Frame: What's On It & How to Prepare (12 min) · Session 2 closes (~75)

Audit-the-AI review moment (the course's recurring habit, one last time before the exam):

Paste to an approved chatbot: "Is negative reinforcement the same as punishment? And do rods let us see color?"
Check it against what we taught. Chatbots sometimes blur negative reinforcement with punishment (it increases behavior) and may get rods/cones backwards. The tool drafts; you judge. If you can catch the model here, you're ready.

What's on the Midterm (state it plainly — put it on the closing slide):
- Coverage: cumulative over Weeks 1–7, Objectives 1–5 — the science of psychology & its perspectives; research methods & ethics; the biological bases of behavior; sensation, perception & consciousness; and learning & memory. It does not include the cognition, intelligence, motivation, development, or social material that starts in Week 9.
- Format & weight: 20 items, 100 points (5 each) — all concept and scenario items (no arithmetic): recognize a perspective, name an IV/DV, match a brain structure, tell sensation from perception, label a CS/CR, or judge a reinforcement-vs-punishment scenario. Mixed item types (mostly multiple-choice, plus a matching, a multiple-answer, and true/false). The Midterm is 20% of the course grade and replaces Quiz 8 and Assignment 8. Window opens Mon Oct 19; exam due Sun Oct 25, 11:59 p.m.
- Coverage weight (so you study proportionally): Obj 1 ≈ 3 items · Obj 2 ≈ 3 · Obj 3 ≈ 3 · Obj 4 ≈ 5 · Obj 5 ≈ 6 — learning & memory is the biggest slice; sensation/perception/consciousness is next.

The preparation plan (point at each artifact by name):
1. Study Guide — work it first; it's the checklist of every move across the five objectives.
2. Exam-Prep Tutorial — run it with an approved chatbot (Gemini / Claude / ChatGPT) and submit the share link; it diagnoses and drills your weak spots adaptively.
3. Practice Exam — sit it timed, like the real thing, then review what you missed against the Study Guide.
4. Discussion 8 (the debrief) — after the exam, reflect on your prep and performance and build a study plan going forward.

Callback + tease:
- Callback: "Every item on Thursday's exam is a move you already made in Weeks 1–7 — today we just named it and found where it slips."
- Tease next: "After the midterm, Week 9 opens the back half — cognition, language, and intelligence: how we think, solve problems, and where reasoning predictably goes wrong."

Hand-off (the week's work): review the Study Guide, run the Exam-Prep Tutorial (share link), take the Practice Exam, sit the Midterm (due Sun Oct 25), and post Discussion 8 (the midterm debrief, due Sun Oct 25).

Instructor FAQ — Common Stumbles (Review Week)

Student says / does	Quick cure
Treats the six perspectives as rivals where one "wins."	They're levels of analysis, not competitors. "Anxiety is just brain chemistry" is like "a novel is just ink." Ask what each lens reveals.
Credits functionalism to Wundt, or calls Freud the founder of scientific psychology.	Wundt, 1879 founded the science. Structuralism named the parts (Wundt/Titchener); functionalism asked the purpose (William James).
Calls a strong correlation "proof" of cause.	Ask: was anything randomly assigned? No → it's a link. Hunt the third variable; check directionality.
Swaps random sampling and random assignment.	Sampling = who's studied → generalize. Assignment = who's treated → cause. Different jobs.
Believes the "10% of the brain" myth, or that neurons touch.	Imaging shows whole-brain activity. The signal is electrical inside, chemical across the synaptic gap — neurons don't touch.
Thinks a bigger stimulus makes a bigger action potential.	Firing is all-or-none. A stronger stimulus makes a neuron fire more often, not "bigger."
Says rods let us see color, or that the brain shuts off in sleep.	Cones = color & detail (rods = dim light, black-and-white). The sleeping brain is active, especially in REM — "asleep is not unplugged."
Calls negative reinforcement a kind of punishment.	Negative reinforcement INCREASES behavior by removing something aversive (seatbelt beep stops). Reinforcement ↑, punishment ↓; +/− = add/remove.
Thinks memory is a recording.	Memory is reconstructive — rebuilt from fragments and editable (the misinformation effect). Confidence ≠ accuracy.
Panics that the exam is "everything."	It's Objectives 1–5 only (Weeks 1–7). Cognition, development, and social (Weeks 9+) are not on the midterm. Bound the studying.

Scope flag

This outline is pure review of Objectives 1–5 — no new material. The few framing extras (the "10%" cold open, the BINS-style mnemonics, the audit-the-AI habit) are retained context carried over from Weeks 1–7 because they make the cures stick; cut them for a leaner 60-minute review. Real historical figures (Wundt, James, Watson, Skinner, Freud, Rogers, Maslow, Pavlov, Bandura, Loftus) are referenced factually as the discipline's history; the instructor and institution remain fictional. The midterm and its bundle (Study Guide, Exam-Prep Tutorial, Practice Exam) are built separately and only referenced here by name.
