Book Isle synesthesia reading: separate sound description from cross-sensory modifiers

English translation of the Chinese original, translated on 2026-11-14. Original publication dates, attribution, code and version notes are retained.

A “cool bell sound” does not establish that the bell lost temperature. Read a short passage in Book Isle and trace the modified object, borrowed sense and any actual tea-drinking action. Terminology supports reading; the app neither automatically classifies synesthesia nor diagnoses perception from words.

Preserve an original passage and location anchor

Create an editable TXT or another currently readable format with passage A: “The bell sound carried a mint-like coolness and slid past her ears. She finished the mint tea in her cup, pushed open the door and walked toward the square.” Add chapter title “After the Bell”, retain the original and open a copy through existing import controls. Record title, opening words and both sentences, not just “mint”. If selection is unavailable, copy key phrases externally; do not assume identical highlighting across formats or overwrite the sole source needed for comparison.

Identify two senses using the term’s definition

The Academy of American Poets glossary explains synesthesia as describing one sense through another. Here bell sound is auditory; borrowed coolness is tactile/thermal, while “mint-like” may evoke taste or smell. Record auditory and tactile domains as explicit, keeping taste/smell as possible associations rather than forcing all five senses from the word mint. The source supplies literary terminology, not evidence that the character literally sees sounds, that the author has a physiological condition or that every reader feels the same effect.

Check modification word by word before excerpting

Split the first sentence into bell sound, carried, mint-like coolness, and slid past her ears. Coolness describes the sound’s felt quality rather than reporting a hand touching cold metal. Record the motion expression separately: it describes passing sound without adding a visible moving object. An excerpt reduced to “she heard mint” changes syntax and action; restore the full sentence. Every note needs both described object and modifier, or the cross-sensory relationship collapses into an isolated adjective whose target cannot be checked.

Keep literal tea-drinking stimuli separate

Sentence two explicitly has her finish mint tea: record a beverage and the character’s drinking action. It states neither tea temperature nor that drinking caused the bell’s coolness, so temperature and causation remain unspecified. Do not transfer sentence-one coolness into the cup-temperature field or use literal mint in sentence two to prove sentence one purely auditory. The images may echo, but resonance and physical causation are different judgments. Preserve locations and evidence rather than merging figure, sensory language and event into one factual excerpt.

Add an ordinary multisensory comparison

Write passage B: “She heard the bell, held the cool cup and smelled the mint in it.” Hearing belongs to the bell, touch to the cup and smell to the scent. Merely listing three senses does not establish synesthesia: ask whether one sensory vocabulary modifies another sensory object. Keep separate A/B records and identify what coolness modifies without consulting labels. Multisensory listing and cross-sensory description are different conditions. Passage B is not inferior writing merely because it lacks the target figure; it is a control with different conditions.

Change one modifier target for a minimal comparison

Change the sentence to “The clear bell rang; she touched the cup that carried a coolness.” Sound retains an auditory quality while coolness returns to the cup. Preserve both versions and show the changed modifier target rather than merely labelling before/after. “Clear” may itself invite visual associations, but conventional adjectives need not all receive forced classifications. The central evidence remains the original explicit transfer of thermal sensation to sound. For ambiguous meanings, retain a main reading, alternatives and supporting words rather than inventing a final app or dictionary score.

Troubleshoot wrapping and sensory overinterpretation

If wrapping places coolness on another line, restore the sentence before checking modification; display wrapping does not break syntax. If a copy loses a full stop, consult the original to separate bell description from drinking, rather than interpreting damaged formatting as a new figure. Similar phrases such as “sweet sound” require context: sweet may convey emotional evaluation or taste transfer. Preserve uncertainty instead of classifying by word form alone. Neither fictional nor real sensory conditions are inferred from literary wording, and no physical-device perception experiment is claimed.

Reopen and rebuild the three-column record

Save notes, leave and reopen the passage through chapter title and opening words. Without labels rebuild three fields: bell sound as target, coolness as borrowed sense and tea drinking as literal action. Re-read B, assigning each sense its own stimulus without classifying by sensory count. Retain character, sentence and location so abbreviated mint notes return to full context. If font changes affect pagination, use opening words instead of assuming fixed page numbers. Explain the cross-sensory relationship word by word while retaining unspecified conditions, without inferring automatic classification or author perception.
