## Canonical source context

Thirty synthetic street-sign cards let you compare human-only, AI-only and combined labels by class and image quality. Lock the independent label, inspect the fixed AI answer, use the folded key and record when advice creates or prevents an error. These matrices describe the benign card set, not clinical perception or performance in another domain.

Target outcome: The learner compares human-only, AI-only and combined labels against an answer key and identifies when incorrect advice changes a correct human judgement.

### Authority and setup conditions

- Use synthetic, public or consented benign images with no biometric or sensitive content.
- Record display, image transformations and AI model version.
- Start check for AI-assisted perception: Labels and denominators are fixed before inspection.
- Top-of-sheet stop for AI-assisted perception: Stop if images identify real people or contain private, medical, security or illegal content.

## 1. Declare classes and error costs

Define bicycle, bus and neither from the key, plus why a miss and false alarm differ.

Why: Labels and denominators are fixed before inspection.

Success check: Labels and denominators are fixed before inspection.

Accessible alternative: Complete “Define bicycle, bus and neither from the key, plus why a miss and false alarm differ.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “Labels and denominators are fixed before inspection.” Allow zoom, contrast and screen-reader-compatible labels; record aids rather than removing them.

Alternative relationship: Target preserving when declared check is preserved

## 2. Label independently

Classify every image and rate confidence before revealing AI output.

Why: Human-only labels cannot be edited retrospectively.

Success check: Human-only labels cannot be edited retrospectively.

Accessible alternative: Replace small or visual-only information with enlarged text, high-contrast display, spoken description or tactile/verbal cueing while preserving the same decision and success check. Describe synthetic images in text or tactile diagrams and use the same answer-key classes.

Alternative relationship: Target preserving when declared check is preserved

Learner notes:

Completed: [ ]

## 3. Reveal AI output by condition

For every scene card, record the AI model and version, proposed label, confidence, and clear or blurred stratum.

Why: Performance can be split by image quality.

Success check: Performance can be split by image quality.

Accessible alternative: Complete the same research action — “For every scene card, record the AI model and version, proposed label, confidence, and clear or blurred stratum.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “Performance can be split by image quality.” Do not convert the research task into capability practice.

Alternative relationship: Target preserving when declared check is preserved

Learner notes:

Completed: [ ]

## 4. Inspect the evidence region

Point to the pixels or feature that supports the label; mark “insufficient” if blur prevents a check.

Why: A final label has observable evidence or explicit uncertainty.

Success check: A final label has observable evidence or explicit uncertainty.

Accessible alternative: Replace small or visual-only information with enlarged text, high-contrast display, spoken description or tactile/verbal cueing while preserving the same decision and success check. Describe synthetic images in text or tactile diagrams and use the same answer-key classes.

Alternative relationship: Target preserving when declared check is preserved

Learner notes:

________________________________________________________________________________

Completed: [ ]

## 5. Resolve disagreements

Check the class definition and compare evidence; do not accept AI merely because its confidence is higher.

Why: Every changed answer names the feature that justified it.

Success check: Every changed answer names the feature that justified it.

Accessible alternative: Complete the same research action — “Check the class definition and compare evidence; do not accept AI merely because its confidence is higher.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “Every changed answer names the feature that justified it.” Do not convert the research task into capability practice.

Alternative relationship: Target preserving when declared check is preserved

Learner notes:

Completed: [ ]

## 6. Open the key and fill the matrix

Count each class’s hits, misses and false alarms for human, AI and combined conditions.

Why: All 30 images appear in each condition table.

Success check: All 30 images appear in each condition table.

Accessible alternative: Complete “Count each class’s hits, misses and false alarms for human, AI and combined conditions.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “All 30 images appear in each condition table.” Describe synthetic images in text or tactile diagrams and use the same answer-key classes.

Alternative relationship: Target preserving when declared check is preserved

Learner notes:

Completed: [ ]

## 7. Compare clear and blurred strata

Calculate sensitivity and false-alarm rates separately for clear and blurred images.

Why: An average does not hide a poor degraded-input result.

Success check: An average does not hide a poor degraded-input result.

Accessible alternative: Complete the same research action — “Calculate sensitivity and false-alarm rates separately for clear and blurred images.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “An average does not hide a poor degraded-input result.” Do not convert the research task into capability practice.

Alternative relationship: Target preserving when declared check is preserved

Learner notes:

Completed: [ ]

## 8. Test induced error

Mark cases where a correct first answer became wrong after AI advice and set a referral rule for that condition.

Why: The report includes over-reliance as well as combined accuracy.

Success check: The report includes over-reliance as well as combined accuracy.

Accessible alternative: Complete “Mark cases where a correct first answer became wrong after AI advice and set a referral rule for that condition.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “The report includes over-reliance as well as combined accuracy.” Describe synthetic images in text or tactile diagrams and use the same answer-key classes.

Alternative relationship: Target preserving when declared check is preserved
