# PWR-172 — Social signal detection: learner worksheet Release: Revision 7T · Full Tutorial Edition Estimated time: Estimated 31 min reading and worksheet pass Difficulty: Intermediate Equipment: Common household or practice equipment — Declared Social signal detection fixture: A fictional set contains 20 short video descriptions: five show a declared “request to pause” signal and 15 do not. Culture and protected characteristics are removed, and an answer key defines the target.; Setup aid for Count the base rate: Prepare a four-cell error table and a separate uncertainty count.; Social signal detection log: Sensitivity, specificity and target-corrected classification for a declared signal set; retain Social signal detection errors, assistance, stop and fallback.; Signal-claim check: place “A randomized controlled trial of training of affect recognition in schizophrenia shows lasting effects for theory of mind” beside “The Social and Cognitive Online Training (SCOT) project: A digital randomized controlled trial to promote socio-cognitive well-being in older adults”. For each, list the exact task and scored outcome. Contrast them with the pause-signal cards, write “no lie, emotion or intent inference” beside the matrix, and use the worker-monitoring guidance to define prohibited collection and action.; Supplied 20-card set (keep the key folded until all labels are locked): 1 “Could we slow down?”. 2 “Please pause now”. 3 speaker looks at notes and continues. 4 “I have a question after this”. 5 “Could you repeat that?”. 6 speaker raises the agreed blue pause card. 7 “Let’s continue after lunch”. 8 speaker scratches their head and keeps talking. 9 “I need a quieter room”. 10 “Stop for a moment, please”. 11 speaker raises a red folder. 12 “I’m ready to continue”. 13 camera turns off without a message. 14 blurred video shows a blue rectangular card that may be the agreed card. 15 “Can we review that now?”. 16 “Please speak more slowly”. 17 muffled audio contains “Could we …”? with no visible card. 18 “I need us to pause”. 19 silence follows a question. 20 speaker raises a blue notebook rather than the agreed card.; Folded scoring key and demonstration response: true targets are 2, 6, 10, 14 and 18; every other ID is non-target. For the demonstrated 4/5 result, lock TARGET on 2, 6, 10, 15, 18 and 20; mark 14 and 17 uncertain. For the four-cell matrix, uncertain is not a positive label: TP=4, FN=1, FP=2 and TN=13; the separate uncertainty count is 2. Space: Desk / seated Automated structural checklist: 10 of 10 structural checks present Evidence quality/context: G6; Detailed research depth Automated method-quality band: Comprehensive Method-rating basis: Structure coverage, instruction/check specificity, alternative distinctness, source troubleshooting, comparison depth and whether purpose/check fields are authored rather than derived. Editorial review: Pending manual editorial sign off ## Before you begin - [ ] I read the tutorial authority and stop conditions. - [ ] I have the required equipment/space or a declared accessible alternative. ## Canonical source context The artificial pause-signal deck turns an ambiguous social cue into a transparent classification problem with a supplied key and base rate. Count hits, misses and false alarms, preserve uncertainty, and choose only reversible responses. A 4/5 sensitivity result on these cards cannot reveal emotion, honesty or anyone’s real intention. Target outcome: The learner separates signal from interpretation, uses a declared label set and base rate, calculates misses and false alarms, and chooses a reversible response. ### Authority and setup conditions - Use only fictional or consented training material with protected characteristics removed. - Prepare a four-cell error table and a separate uncertainty count. - Start check for Social signal detection: The label can be scored from the case without guessing an inner state. - Top-of-sheet stop for Social signal detection: Stop if the exercise begins to identify, rank, monitor or investigate a real person. ### Required or supplied materials - Declared Social signal detection fixture: A fictional set contains 20 short video descriptions: five show a declared “request to pause” signal and 15 do not.

For the four-cell matrix, uncertain is not a positive label: TP=4, FN=1, FP=2 and TN=13; the separate uncertainty count is 2. ## 1. Name the permitted target Define one observable label, such as “the speaker explicitly says stop or raises the agreed pause card.” Exclude emotion, honesty and intent. Why: The label can be scored from the case without guessing an inner state. Success check: The label can be scored from the case without guessing an inner state. Accessible alternative: Complete “Define one observable label, such as “the speaker explicitly says stop or raises the agreed pause card.” Exclude emotion, honesty and intent.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “The label can be scored from the case without guessing an inner state.” Allow extra review time; do not score response speed as social competence. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Count the base rate Before classifying, record how many target and non-target cases are in the set. Why: The sheet states 5 target and 15 non-target cases. Success check: The sheet states 5 target and 15 non-target cases. Accessible alternative: Complete the same research action — “Before classifying, record how many target and non-target cases are in the set.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The sheet states 5 target and 15 non-target cases.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Inspect one channel at a time Mark the spoken phrase, agreed card or turn-taking event separately; do not blend posture, accent or identity into a feeling score. Why: Each mark names a channel and exact cue. Success check: Each mark names a channel and exact cue. Accessible alternative: A supported, seated, reduced-range or slower version of “Mark the spoken phrase, agreed card or turn-taking event separately; do not blend posture, accent or identity into a feeling score.” is equivalent only when it keeps the same trained or measured target, declared configuration and success check: “Each mark names a channel and exact cue.” If any of those change, record it as a related alternative rather than an equivalent repetition. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Choose target or uncertain Apply the written rule. Use “uncertain” when the cue is obscured rather than forcing yes or no. Why: Every decision cites the rule or states why evidence was missing. Success check: Every decision cites the rule or states why evidence was missing. Accessible alternative: Replace spoken or audio cues with visible text, captions or haptic timing while keeping the same sequence and success check. Replace video descriptions with text, audio or tactile cards while keeping the same explicit target and answer key. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Open the answer key Count true targets found, targets missed, false alarms and correct rejections. Why: The four counts sum to all 20 cases. Success check: The four counts sum to all 20 cases. 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. Allow extra review time; do not score response speed as social competence. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Calculate detection and false alarms Divide targets found by all true targets for sensitivity; divide false alarms by all non-targets for the false-alarm rate. Why: The denominators are 5 and 15, not the number predicted positive. Success check: The denominators are 5 and 15, not the number predicted positive. Accessible alternative: A supported, seated, reduced-range or slower version of “Divide targets found by all true targets for sensitivity; divide false alarms by all non-targets for the false-alarm rate.” is equivalent only when it keeps the same trained or measured target, declared configuration and success check: “The denominators are 5 and 15, not the number predicted positive.” If any of those change, record it as a related alternative rather than an equivalent repetition. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 7. Select a reversible safeguard For an uncertain pause cue, slow or ask a neutral question; do not accuse, diagnose or penalise. Why: The response protects the option to pause without claiming what the person feels. Success check: The response protects the option to pause without claiming what the person feels. Accessible alternative: Replace spoken or audio cues with visible text, captions or haptic timing while keeping the same sequence and success check. Allow extra review time; do not score response speed as social competence. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 8. State the restriction Write that the exercise cannot detect lies, danger, private intent or universal emotion. Why: The final record contains all four non-claims in plain language. Success check: The final record contains all four non-claims in plain language. Accessible alternative: Complete the same research action — “Write that the exercise cannot detect lies, danger, private intent or universal emotion.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The final record contains all four non-claims in plain language.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## Reflection What changed? ________________________________________________________________________________ What remains difficult? ________________________________________________________________________________ What will I repeat, adapt, ask for help with, or stop? ________________________________________________________________________________ --- Completion of this worksheet demonstrates tutorial participation only.
