# PWR-085 — Olfactory discrimination: learner worksheet Release: Revision 7T · Full Tutorial Edition Estimated time: Estimated 23 min reading and worksheet pass Difficulty: Introductory Equipment: Basic stationery or digital tools — No-exposure packet of ten cards, two for each field: identity (‘coffee’, ‘black tea’), quality (‘roasted’, ‘woody’), intensity (‘2 of 5’, ‘very strong’), familiarity (‘smelled most mornings’, ‘new to me’) and liking (‘pleasant’, ‘disliked’). Print the correct field on each card back.; Optional practical packet: three separate closed containers holding labelled familiar foods or drinks already used safely.; A helper-made code key, timer and sheet with identity, quality, intensity, familiarity, liking and confidence fields.; A ventilated room with an immediate way to close containers and leave. Space: Open movement area Automated structural checklist: 10 of 10 structural checks present Evidence quality/context: G1; 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 Smell discrimination means telling declared aromas or aroma features apart. The safest route uses written descriptor cards with no exposure. An optional practical route uses only two or three labelled foods or drinks that the learner already consumes safely, in a ventilated room, with one brief ordinary sniff. The task never uses essential oils, fragrances, cleaners, smoke, spoiled food or unknown substances. Target outcome: The learner completes either a nine-trial familiar-aroma comparison or the supplied ten-card no-exposure sort, separating identity, quality, intensity, familiarity and liking without symptoms or unknown exposure. ### Authority and setup conditions - Use the no-exposure route if there is asthma, allergy, migraine, nausea, pregnancy-related sensitivity, recent smell change or any uncertainty about exposure. - Confirm labels, ingredients, freshness and ordinary safe use; do not ask the learner to ingest anything. - Keep all containers closed except the one in use and agree a stop signal. ### Required or supplied materials - No-exposure packet of ten cards, two for each field: identity (‘coffee’, ‘black tea’), quality (‘roasted’, ‘woody’), intensity (‘2 of 5’, ‘very strong’), familiarity (‘smelled most mornings’, ‘new to me’) and liking (‘pleasant’, ‘disliked’). Print the correct field on each card back. - Optional practical packet: three separate closed containers holding labelled familiar foods or drinks already used safely. - A helper-made code key, timer and sheet with identity, quality, intensity, familiarity, liking and confidence fields. - A ventilated room with an immediate way to close containers and leave. ## 1. Choose the safe route Select descriptor cards only, or select two or three labelled familiar foods already handled without trouble. Write the choice and reason. Why: A deliberate route choice prevents curiosity from turning into an exposure challenge. Success check: The sheet states no-exposure or familiar-aroma and lists every permitted item. Accessible alternative: Complete the same research action — “Select descriptor cards only, or select two or three labelled familiar foods already handled without trouble. Write the choice and reason.” — 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 no-exposure or familiar-aroma and lists every permitted item.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Separate smell dimensions Before any trial, define identity, quality, intensity, familiarity and liking in separate columns. Why: Aroma identity is not the same as strength, pleasantness or personal memory. Success check: The learner can give a different example answer for each column. Accessible alternative: A supported, seated, reduced-range or slower version of “Before any trial, define identity, quality, intensity, familiarity and liking in separate columns.” is equivalent only when it keeps the same trained or measured target, declared configuration and success check: “The learner can give a different example answer for each column.” 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: [ ] ## 3. Code a balanced set For the no-exposure route, shuffle the ten supplied cards face down; turn one at a time without viewing the answer on its back. For the practical route, a helper assigns hidden letter codes and prepares nine trials with each familiar item appearing equally often. Product labels stay available for safety. Why: Balanced coding allows feedback without turning the substance into a mystery. Success check: Card answers or aroma identities remain hidden until the learner commits a field or identity, while every practical ingredient label remains visible. Accessible alternative: Complete “For the no-exposure route, shuffle the ten supplied cards face down; turn one at a time without viewing the answer on its back. For the practical route, a helper assigns hidden letter codes and prepares nine trials with each familiar item appearing equally often. Product labels stay available for safety.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “Card answers or aroma identities remain hidden until the learner commits a field or identity, while every practical ingredient label remains visible.” Use large-print, pictorial or spoken labels while keeping ingredients available. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Take one ordinary sniff On the practical route, open one container at a comfortable ordinary distance, take one brief natural sniff without deep inhalation and close it immediately. On the card route, read one printed phrase once; there is no container or exposure. Why: Long or repeated inhalation increases exposure and adaptation, which can dull later trials. Success check: A practical container is open for one ordinary sniff only, or one card phrase is read once; no extra exposure is introduced. Accessible alternative: Complete the same research action — “On the practical route, open one container at a comfortable ordinary distance, take one brief natural sniff without deep inhalation and close it immediately. On the card route, read one printed phrase once; there is no container or exposure.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “A practical container is open for one ordinary sniff only, or one card phrase is read once; no extra exposure is introduced.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Record before reveal For practical aroma, choose the identity label and then record quality, intensity, familiarity, liking and confidence. For a card, choose exactly one of those five field headings and explain which word makes it fit. Commit before viewing the key. Why: Separate pre-feedback fields show whether a correct label came with calibrated confidence and what feature was perceived. Success check: The practical row or card-field choice and reason are saved before the answer is checked. Accessible alternative: Complete the same research action — “For practical aroma, choose the identity label and then record quality, intensity, familiarity, liking and confidence. For a card, choose exactly one of those five field headings and explain which word makes it fit. Commit before viewing the key.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The practical row or card-field choice and reason are saved before the answer is checked.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Space, reveal and transfer For practical aroma, wait at least one minute in fresh room air, reveal the code and note the missed cue; after 48 hours repeat six trials with changed containers or order, never stronger aromas. For cards, reveal each back after commitment, record any confused field and re-sort the same ten cards after 48 hours in a new order. Why: Spacing limits adaptation; a changed arrangement tests recognition beyond the original sequence. Success check: Practical identity or card-field retest results are recorded separately from the first set, with exposure symptoms marked not applicable on the card route. Accessible alternative: Complete the same research action — “For practical aroma, wait at least one minute in fresh room air, reveal the code and note the missed cue; after 48 hours repeat six trials with changed containers or order, never stronger aromas. For cards, reveal each back after commitment, record any confused field and re-sort the same ten cards after 48 hours in a new order.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person.
