# PWR-088 — Multisensory integration: learner worksheet Release: Revision 7T · Full Tutorial Edition Estimated time: Estimated 21 min reading and worksheet pass Difficulty: Introductory Equipment: Common household or practice equipment — Six clean, blunt, lightweight objects or shapes that can be seen and touched safely.; A tabletop screen, numbered answer options, timer and randomised condition list.; A record for accuracy, time, confidence, cue used and discomfort. Space: Room-scale practice space 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 Multisensory integration is how information from more than one sense is combined. Extra cues can help, do nothing or conflict. This lesson tests the same benign object judgement under vision-only, touch-only and combined conditions, keeping time and answer options fixed. The learner records which cue mattered and whether the combination beats the best single cue. Target outcome: The learner completes 18 balanced object trials and correctly reports whether combined cues improve, match or reduce accuracy relative to the best single-cue condition. ### Authority and setup conditions - Inspect objects and confirm the seated setup allows safe touch without reaching or dropping. - Choose one fixed question, such as which of six shapes is present, and a ten-second observation limit. - Check lighting, visual access and tactile access; retain normal aids. ### Required or supplied materials - Six clean, blunt, lightweight objects or shapes that can be seen and touched safely. - A tabletop screen, numbered answer options, timer and randomised condition list. - A record for accuracy, time, confidence, cue used and discomfort. ## 1. Fix one judgement Choose six objects and one answer set. Ask the identical identity or shape question in every condition. Why: Different questions would confound sensory condition with task difficulty. Success check: The same six answer labels apply to all trials. Accessible alternative: Complete “Choose six objects and one answer set. Ask the identical identity or shape question in every condition.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “The same six answer labels apply to all trials.” A helper may present objects within comfortable reach and record spoken answers without cueing. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Define three conditions Set vision-only with no touch, touch-only behind a screen while seated, and combined vision-plus-touch. Keep the ten-second limit. Why: Explicit conditions make cue contribution observable. Success check: Each condition has a written access rule and equal time. Accessible alternative: A spoken or tactile version of “Set vision-only with no touch, touch-only behind a screen while seated, and combined vision-plus-touch. Keep the ten-second limit.” can rehearse the response sequence, but it removes the declared visual stimulus and is therefore a related activity, not an equivalent attempt at Multisensory integration. To preserve the target, keep the authored visual stimulus and adapt only non-target access such as response input, instructions, breaks or support; retain this success check: “Each condition has a written access rule and equal time.” Alternative relationship: Related alternative changes trained or measured target Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Balance and randomise Prepare six trials per condition in a mixed order, with every object appearing equally often. Why: A mixed balanced schedule reduces learning and order effects. Success check: The list contains 18 trials and no condition or object dominates. Accessible alternative: Complete “Prepare six trials per condition in a mixed order, with every object appearing equally often.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “The list contains 18 trials and no condition or object dominates.” Use enlarged objects, high contrast, tactile markers or extended equal time across all conditions. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Respond and name the cue After each trial, choose an answer, confidence and the feature used, such as outline, texture or both. Why: Cue reports show whether the learner actually used both streams or ignored one. Success check: Every response includes answer, confidence and named cue before feedback. Accessible alternative: A spoken or tactile version of “After each trial, choose an answer, confidence and the feature used, such as outline, texture or both.” can rehearse the response sequence, but it removes the declared visual stimulus and is therefore a related activity, not an equivalent attempt at Multisensory integration. To preserve the target, keep the authored visual stimulus and adapt only non-target access such as response input, instructions, breaks or support; retain this success check: “Every response includes answer, confidence and named cue before feedback.” Alternative relationship: Related alternative changes trained or measured target Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Reveal and repair conflict Check the key. When cues conflict or the combined trial is wrong, identify which cue was misleading and what reliability check could help next time. Why: Integration includes down-weighting an unreliable cue, not merely adding information. Success check: The repair names the misleading cue and a concrete check. Accessible alternative: Complete the same research action — “Check the key. When cues conflict or the combined trial is wrong, identify which cue was misleading and what reliability check could help next time.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The repair names the misleading cue and a concrete check.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Compare conditions Calculate accuracy and median time for each condition. Compare combined performance with the better single condition, then repeat later with two unfamiliar safe objects. Why: The best single-cue comparison reveals benefit, neutrality or interference. Success check: The conclusion says helps, matches or hurts for this task and includes novel-item results. Accessible alternative: Complete the same research action — “Calculate accuracy and median time for each condition. Compare combined performance with the better single condition, then repeat later with two unfamiliar safe objects.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The conclusion says helps, matches or hurts for this task and includes novel-item results.” Do not convert the research task into capability practice.
