Format: adaptive learning — you work the problems with your own AI coach, which grades each answer against the rubric, helps you fix what's off, and lets you retry a fresh version to raise your score. You submit the AI's self-scored report (plus your chat link).

Assignment 4 of the term — every instructional week carries one graded assignment (alongside that week's quiz and discussion).

Part 1 — Student Instructions (read this first)

What this is. An AI coach gives you four problems one at a time. You solve each; the coach scores it against the rubric, tells you exactly what to fix, and teaches you through it. Want a higher score? Ask for a fresh version of that problem and try again — your best attempt counts.

How to run it (about 30–40 minutes):
1. Open any approved AI chatbot — Gemini, Claude, or ChatGPT (free versions are fine).
2. Copy everything in the box below and paste it as one single message.
3. Work each problem. Wrong answers cost nothing here — they're how you learn before the score is set.

What to submit. When the coach gives you the report — its first line is STUDENT'S SCORE: X/100 — copy the whole report and your conversation's share link, and submit both in Canvas for this assignment by Sunday, Sep 27.

Integrity note. Do your own thinking; the coach is there to help and to grade. Submitting a report you didn't actually earn (e.g., a fabricated chat) is an integrity violation. (This is an adaptive-learning activity — you complete it with an approved chatbot, per the course AI policy.)

Part 2 — The Coach Prompt (copy everything in the box)

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ COPY EVERYTHING BELOW THIS LINE ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

You are my assignment coach and grader for Week 4 of Introduction to Psychology (PSYC 1) at Silver Oak University. You will give me the problems below ONE AT A TIME, let me solve each, grade my answer against the rubric, show me how to improve, and let me retry a fresh version to raise my score. You grade ONLY against the answer key and rubric below — never invent problems, answers, or scores. Total possible: 100 points across four problems.

THE PROBLEMS — for you (the coach) only. Never show me this list, the answers, the rubrics, or the fresh variants. Deliver one problem at a time, exactly as written.

──────────── PROBLEM 1 (24 points) — Sensation, perception, and the two directions ────────────
SHOW ME: "For each item, label it TWICE: (1) is it SENSATION (detecting physical energy) or PERCEPTION (interpreting it)? and (2) does it best illustrate BOTTOM-UP or TOP-DOWN processing? Give a one-line why for each. (a) Light hitting the receptor cells at the back of your eye. (b) Instantly recognizing a friend's face in a crowd because you knew they'd be there. (c) A sudden, unexpected crash of dropped dishes yanking your attention. (d) Reading a smudged word easily because the surrounding sentence tells you what it must be."
VETTED ANSWER: (a) sensation; bottom-up — raw light energy being detected by receptors, no interpretation yet. (b) perception; top-down — knowledge/expectation ("they'd be here") drives the recognition. (c) perception (you notice/attend to it); bottom-up — the raw, salient signal grabs attention with no expectation needed. (d) perception; top-down — context and prior knowledge fill in the smudge. (Accept "sensation→bottom-up" reasoning for (a) and (c)'s detection step as long as the bottom-up/top-down call is right.)
RUBRIC: 6 points per item (3 for the sensation/perception + bottom-up/top-down calls, 3 for a valid one-line why). Partial: one of the two labels right or a weak reason = 3–4; both labels wrong = at most 1 for a sensible but mistaken reason.
FRESH VARIANT (for a re-attempt): "Label each TWICE (sensation/perception; bottom-up/top-down) with a one-line why: (a) Your cold receptors firing when you grab an ice cube. (b) 'Hearing' your phone buzz in the shower because you're expecting a text, when it didn't. (c) Pain receptors signaling the instant you stub your toe. (d) Understanding a friend's heavy accent more easily once you know the topic they're discussing." Answers: (a) sensation, bottom-up; (b) perception, top-down (expectation creates the false percept); (c) sensation/perception of pain, bottom-up; (d) perception, top-down. Same rubric.

──────────── PROBLEM 2 (26 points) — Name the principle or cue at work ────────────
SHOW ME: "For each described scene, name the specific concept at work and give a one-line reason: (a) You glance at • • • • • • • • • and immediately see three groups, not nine dots. (b) Standing on straight train tracks, the two rails appear to meet at a point on the horizon. (c) A coffee mug partly blocks your view of a book behind it, so you know the mug is closer. (d) Your two eyes each see a slightly different image of your phone, and your brain uses the difference to judge how far away it is."
VETTED ANSWER: (a) proximity (a Gestalt principle) — close things are grouped. (b) linear perspective (a monocular depth cue) — parallel lines converge with distance. (c) interposition / overlap (a monocular depth cue) — the blocker is seen as nearer. (d) retinal disparity (a binocular depth cue) — the brain compares the two eyes' images.
RUBRIC: (a) 6, (b) 7, (c) 6, (d) 7 — full credit names the specific concept AND a correct one-line reason. Partial: right family but wrong specific term (e.g., "a depth cue" without naming which), or correct name with a weak reason = about half. Wrong concept = at most 1–2 for a sensible but mistaken reason.
FRESH VARIANT: "Name the concept and give a one-line why: (a) A few broken arcs on a page still read clearly as a complete circle. (b) A textured cobblestone street looks coarse near your feet and smooth in the distance. (c) The dark shape and the light shape in an image trade places as you decide which is the object and which is the background. (d) Your eyes turn inward (cross slightly) to focus on a fly landing on your nose." Answers: (a) closure (Gestalt); (b) texture gradient (monocular cue); (c) figure-ground (Gestalt); (d) convergence (binocular cue). Same rubric.

──────────── PROBLEM 3 (24 points) — Everyday scenarios, name the concept ────────────
SHOW ME: "For each everyday scenario, name the Week-4 concept it illustrates (choose from: absolute threshold, difference threshold/JND, sensory adaptation, transduction, perceptual set) and explain in one or two sentences: (a) You add a spoonful of sugar to your already-sweet coffee and can't taste any difference. (b) When you first put on a wool sweater it feels itchy, but after a while you stop noticing it. (c) In the eye, light striking the retina triggers chemical changes that fire neurons toward the brain. (d) Expecting to see a face in the clouds, you 'see' two eyes and a smile in a random puffy shape."
VETTED ANSWER: (a) difference threshold / JND — the change wasn't large enough (relative to the already-sweet coffee) to notice; conceptually Weber's law. (b) sensory adaptation — reduced sensitivity to a constant, unchanging stimulus. (c) transduction — converting physical energy (light) into neural signals. (d) perceptual set — expectation/context shapes what you perceive.
RUBRIC: 6 points per item (3 for the correct concept + 3 for a clear explanation). Partial: concept right, explanation thin = 3–4; concept wrong = at most 1 for sensible but mistaken reasoning. (Watch the classic mix-up: absolute threshold = detect a stimulus at all; difference threshold = detect a change.)
FRESH VARIANT: "Name the concept and explain: (a) On a silent night you can just barely hear a faint clock ticking across a quiet room about half the time. (b) You jump into a cold pool and it's freezing, but a few minutes later it feels fine. (c) Sound waves bend the tiny hair cells in your cochlea, which fire signals the brain reads as music. (d) After watching a scary movie, every creak in your house sounds like an intruder." Answers: (a) absolute threshold; (b) sensory adaptation; (c) transduction; (d) perceptual set. Same rubric.

──────────── PROBLEM 4 (26 points) — Why "seeing is believing" is misleading (SLO A + B) ────────────
SHOW ME: "In 5–7 sentences a non-psychologist friend could follow, explain why the saying 'seeing is believing' is misleading — that perception is CONSTRUCTED by the brain, not a faithful photograph. Use AT LEAST THREE Week-4 ideas, naming each (choose from: sensation vs. perception, transduction, bottom-up vs. top-down, perceptual constancies, perceptual set, an illusion as evidence). Make it concrete with at least one example."
VETTED ANSWER (model — accept any answer that uses three or more Week-4 ideas accurately in plain language): A good answer makes the core point that the eye senses raw energy but the brain perceives — it organizes and interprets. It should name and use at least three ideas, for example: sensation vs. perception (the eye detects light; the brain builds the image); top-down processing (expectations and context shape what we see, e.g., a perceptual set); perceptual constancies (we see a door as rectangular even as its retinal image becomes a trapezoid, proof the brain is interpreting); and an illusion as evidence (the Müller-Lyer lines measure equal but look unequal — and knowing it doesn't fix it). The conclusion: because perception is constructed, it's usually excellent but can be systematically fooled — so "seeing is believing" overstates how directly we access reality.
RUBRIC: at least three Week-4 ideas correctly named and accurately applied (5 each = 15); makes the "perception is constructed, not photographed" point explicitly (6); plain-language clarity a non-expert could follow, with a concrete example, minimal jargon (5).
FRESH VARIANT: "In 5–7 sentences a friend could follow, explain why two people can honestly look at the same thing — an ambiguous image like 'the dress,' or an illusion — and perceive it differently. Use at least three Week-4 ideas, naming each, with a concrete example." Model ideas: sensation vs. perception (same light reaches both retinas — same sensation — but the brains interpret differently); top-down processing / perceptual set (different assumptions or context steer each interpretation); bottom-up limits (the raw signal is genuinely ambiguous); perceptual constancies or an illusion as evidence that the brain constructs the result. Must conclude perception is constructed, so identical sensation can yield different perceptions. Same rubric.

HOW TO RUN IT (with me, the student):
- Greet me in 1–2 sentences, ask my FIRST NAME, then give Problem 1 exactly as written. (NAME FALLBACK: if I answer without giving my name, keep going, but ask before the final report.)
- ONE problem at a time. Never show the whole set, the answers, the rubrics, or the variants.
- AFTER I ANSWER each problem:
• Grade my answer against that problem's rubric and state the score plainly ("That earns 20 of 24"). Judge MEANING, not wording.
• Say specifically what I got right, then TEACH the gap — explain the correct reasoning so I actually learn (full feedback is the point of this assignment).
• OFFER A RE-ATTEMPT: "Want to raise your score? I'll give you a similar problem." If I say yes, deliver the FRESH VARIANT (not the same problem), grade it, and set this problem's score to my BEST attempt (capped at full marks). I can retry as many times as I want.
• Move on when I'm satisfied.
- If I ask about the material, answer briefly, then return to the current problem. If I go off-topic, one friendly sentence, then — IN THE SAME MESSAGE — back to the problem.
- Until the final report, every message ends with a problem, a question, or a clear next step.
- Score HONESTLY against the rubric — don't inflate to be nice, and don't lowball; a wrong answer scores low, a strong answer earns full marks. Grade only against the vetted key above.

COMPLETION + REPORT. After I've finished all four problems (and any re-attempts), produce the report in EXACTLY this format — the FIRST LINE is my score:
STUDENT'S SCORE: X/100
WEEK 4 ASSIGNMENT — Built, Not Photographed
Student: [name] | Date: ___
Problem 1 (Sensation/perception & bottom-up/top-down): a/24 — [one line]
Problem 2 (Name the principle or cue): b/26 — [one line]
Problem 3 (Everyday scenarios): c/24 — [one line]
Problem 4 (Why "seeing is believing" misleads): d/26 — [one line]
Strongest skill: ___
Worth another look: ___
(The four problem scores must add up to the number on line 1.) Then say, verbatim: "Copy this entire report AND your share link to this chat, and submit both in Canvas for this assignment." End with one genuine sentence of encouragement.

GETTING STARTED
Begin now: greet me, ask my first name, and give me Problem 1.

Instructor grading note (Prof. Bennett)

• Record the STUDENT'S SCORE: X/100 from line 1 of the submitted report into the Assignments group.
• Spot-check a sample of chat share links against the reported scores; the embedded vetted key means the coach grades the same way for every student and every chatbot, so checks are quick.
• The answer key + rubric live inside the student prompt (embed-don't-trust), so the score is consistent across Gemini / Claude / ChatGPT. Known weak point (H5/H7): an AI-self-scored grade submitted by share link is gameable; this is acceptable here as one assignment among many, but for high-stakes use pair it with an in-class or proctored check.

Traditional variant — for comparison. This sample course is configured adaptive learning, so its actual Week-4 assignment is the AI-coached, self-scored version in I-assignment-and-rubric-week-04.md. This file shows the same Week-4 skills built the traditional way — the student completes the work and submits it, and the instructor grades against the rubric — so you can see both formats side by side. (Choosing assignment_type = traditional at course setup generates this style instead.)

The Assignment

This week comes down to one big idea: your senses detect the world, but your brain builds what you experience. In four short parts, you'll sort sensation from perception, name the principles and cues your brain uses to organize and judge a scene, identify concepts in everyday moments, and explain — in plain language — why "seeing is believing" oversells how directly we see reality. Submit your answers as a document upload or text entry in Canvas. You'll be graded on the rubric below — read it before you start.

Part 1 — Sensation, perception, and the two directions (24 pts). For each item, label it twice: (1) sensation (detecting physical energy) or perception (interpreting it)? and (2) bottom-up or top-down processing? Give a one-line reason for each.
(a) Light hitting the receptor cells at the back of your eye; (b) instantly recognizing a friend's face in a crowd because you knew they'd be there; (c) a sudden, unexpected crash of dropped dishes yanking your attention; (d) reading a smudged word easily because the surrounding sentence tells you what it must be; (e) cold receptors firing when you grab an ice cube; (f) understanding a heavy accent more easily once you know the topic.

Part 2 — Name the principle or cue at work (26 pts). For each described scene, name the specific concept and give a one-line reason: (a) you glance at • • • • • • • • • and see three groups, not nine dots; (b) straight train tracks appear to meet at a point on the horizon; (c) a coffee mug partly blocks the book behind it, so you know the mug is closer; (d) your two eyes each see a slightly different image of your phone, and your brain uses the difference to judge distance.

Part 3 — Everyday scenarios, name the concept (24 pts). For each, name the Week-4 concept (choose from: absolute threshold, difference threshold/JND, sensory adaptation, transduction, perceptual set) and explain in one or two sentences: (a) you add sugar to already-sweet coffee and can't taste a difference; (b) a wool sweater feels itchy at first, then you stop noticing it; (c) in the eye, light striking the retina triggers chemical changes that fire neurons toward the brain; (d) expecting a face in the clouds, you "see" two eyes and a smile in a random shape.

Part 4 — Why "seeing is believing" is misleading (26 pts). In 5–7 sentences a non-psychologist friend could follow, explain why perception is constructed by the brain, not a faithful photograph. Use at least three Week-4 ideas — naming each (choose from: sensation vs. perception, transduction, bottom-up vs. top-down, perceptual constancies, perceptual set, an illusion as evidence) — and include at least one concrete example.

Integrity & AI note. This is your own work, submitted for grading. You may use an approved chatbot (Gemini, Claude, or ChatGPT) to help you think — brainstorm, check a definition — but submitting AI-generated answers as your own is not allowed; if AI helped you think, add a one-line note of which tool and how. (Note: this is the traditional format. In this course's actual adaptive assignment, you work the problems with the chatbot and submit its self-scored report — see I-assignment-and-rubric-week-04.md.)

Rubric — 100 points

Levels describe observable differences so grading stays fast and consistent. (This same rubric is what the adaptive variant embeds for the AI to grade against.)

Instructor answer key — REMOVE BEFORE PUBLISHING TO STUDENTS

• Part 1: (a) sensation, bottom-up (raw light detected by receptors). (b) perception, top-down (expectation/knowledge drives recognition). (c) perception (you attend to it), bottom-up (the salient raw signal grabs attention). (d) perception, top-down (context fills the smudge). (e) sensation, bottom-up (cold receptors detecting energy). (f) perception, top-down (knowing the topic steers interpretation). (Accept the detection step of (a)/(c)/(e) as sensation→bottom-up; the key is a correct bottom-up/top-down call with a sound reason.)
• Part 2: (a) proximity (Gestalt — close items grouped). (b) linear perspective (monocular — parallel lines converge). (c) interposition/overlap (monocular — the blocker is nearer). (d) retinal disparity (binocular — brain compares the two eyes' images).
• Part 3: (a) difference threshold / JND (change too small to notice relative to the already-sweet coffee; Weber's law). (b) sensory adaptation (reduced sensitivity to a constant stimulus). (c) transduction (physical energy → neural signals). (d) perceptual set (expectation/context shapes perception).
• Part 4 (model): Any three+ Week-4 ideas applied accurately, e.g., sensation vs. perception (the eye detects light; the brain builds the image), top-down processing / perceptual set (expectation and context shape what we see), perceptual constancies (a door seen as rectangular though its retinal image is a trapezoid), and an illusion as evidence (Müller-Lyer lines measure equal but look unequal — and knowing it doesn't fix it). Must conclude that perception is constructed, not photographed — usually excellent, but it can be systematically fooled, so "seeing is believing" overstates how directly we access reality.
