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 Spatial memory includes location, landmark identity, route order and relative configuration. This lesson isolates location and relation memory using a small grid. The learner studies six landmarks for a fixed time, hides the layout, reconstructs it, measures positional error, waits and tries a novel layout. Repeated-scene memory and new-layout transfer are reported separately. Target outcome: The learner reconstructs six landmarks on delayed and novel grids, reporting exact locations, identity swaps and a declared median location error without collapsing them into one score. ### Authority and setup conditions - Choose distinct, non-sensitive fictional landmarks. - Fix a 60-second study interval and two-minute reconstruction interval. - Decide whether location, identity and relation will be scored and keep the rule constant. ### Required or supplied materials - Two 5-by-5 grids, six distinct landmark tokens or symbols and matching blank grids. - Timer, cover sheet, coordinate key and scoring record. - Optional tactile grid and raised tokens. ## 1. Label the frame Mark north, rows and columns and place six distinct landmarks on the study grid. Why: A common coordinate frame makes location errors measurable. Success check: Every square and landmark has a unique label. Accessible alternative: Complete “Mark north, rows and columns and place six distinct landmarks on the study grid.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “Every square and landmark has a unique label.” Allow verbal coordinates with a scribe. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Bind identity to location For each landmark, make one short relation statement that joins its identity to a coordinate and neighbour, such as “Pond at C4, east of Gate.” Why: Identity–location binding helps distinguish a forgotten place from a token swap. Success check: Six distinct binding statements are recorded without making a story that changes the supplied layout. Accessible alternative: Complete “For each landmark, make one short relation statement that joins its identity to a coordinate and neighbour, such as “Pond at C4, east of Gate.”” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “Six distinct binding statements are recorded without making a story that changes the supplied layout.” Use fewer landmarks as a separate baseline and progress by stable accuracy, not by removing aids. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Study relations For 60 seconds, name each location and at least two relations, such as café north of pond. Why: Relational encoding supports reconstruction beyond a visual snapshot. Success check: All six positions and two relations are spoken or written. Accessible alternative: Complete “For 60 seconds, name each location and at least two relations, such as café north of pond.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “All six positions and two relations are spoken or written.” Use raised-line grids and distinguishable tactile tokens. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Hide completely Cover the study grid and remove duplicate cues before starting the two-minute reconstruction. Why: A complete hide prevents copying. Success check: No source coordinate or shadow remains visible. Accessible alternative: A supported, seated, reduced-range or slower version of “Cover the study grid and remove duplicate cues before starting the two-minute reconstruction.” is equivalent only when it keeps the same trained or measured target, declared configuration and success check: “No source coordinate or shadow remains visible.” 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: [ ] ## 5. Reconstruct and commit Place all six landmarks on a blank grid, then mark confidence for each before reveal. Why: Committing all positions exposes omissions and swaps. Success check: Six locations and six confidence ratings are saved. Accessible alternative: Complete “Place all six landmarks on a blank grid, then mark confidence for each before reveal.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “Six locations and six confidence ratings are saved.” Use fewer landmarks as a separate baseline and progress by stable accuracy, not by removing aids. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Answer relation probes Before revealing the key, answer four questions about north–south order, nearest neighbours and which two landmarks share a row or column. Why: Relational probes show whether the layout survives beyond exact coordinate recall. Success check: Four answers are committed and later scored separately from token positions. Accessible alternative: Complete “Before revealing the key, answer four questions about north–south order, nearest neighbours and which two landmarks share a row or column.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “Four answers are committed and later scored separately from token positions.” Use raised-line grids and distinguishable tactile tokens. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 7. Calibrate location confidence Sort the six placements into low, medium and high confidence before reveal, then compare exact-position rates in those groups. Why: Useful spatial confidence should rise with correctness rather than merely with familiarity. Success check: The learner can state whether high-confidence placements were more often exact and lowers future confidence when they were not. Accessible alternative: Complete the same research action — “Sort the six placements into low, medium and high confidence before reveal, then compare exact-position rates in those groups.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The learner can state whether high-confidence placements were more often exact and lowers future confidence when they were not.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 8. Measure errors Reveal the key. Count exact positions, identity swaps and Manhattan distance—the horizontal plus vertical squares—from each correct position. Why: Exact hits and distance show different aspects of error. Success check: Each landmark has exact/not exact and distance error. Accessible alternative: A supported, seated, reduced-range or slower version of “Reveal the key. Count exact positions, identity swaps and Manhattan distance—the horizontal plus vertical squares—from each correct position.” is equivalent only when it keeps the same trained or measured target, declared configuration and success check: “Each landmark has exact/not exact and distance error.” 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: [ ] ## 9. Delay and use a novel layout After 48 hours, reconstruct the old grid without restudy, then study and reconstruct a new arrangement with the same rules. Why: Old-layout retention and new-layout method transfer must be separated. Success check: The report contains delayed-old and novel-layout scores. Accessible alternative: Complete “After 48 hours, reconstruct the old grid without restudy, then study and reconstruct a new arrangement with the same rules.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “The report contains delayed-old and novel-layout scores.” Use raised-line grids and distinguishable tactile tokens. 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.
