synesthesia
Let an agent explain synesthesia and its forms, relay research on its basis, prevalence and testing from neuroscience and psychology sources with attribution, describe experiences respectfully, and distinguish synesthesia from metaphor, hallucination and sensory disorders.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain synesthesia and its forms, relay research on its basis, prevalence and testing from neuroscience and psychology sources with attribution, describe experiences respectfully, and distinguish synesthesia from metaphor, hallucination and sensory disorders.
A perceptual phenomenon in which stimulation of one sensory or cognitive pathway involuntarily and consistently evokes experiences in another, such as grapheme-colour synesthesia in which letters or numbers evoke colours, chromesthesia in which sounds evoke colours, phoneme-colour synesthesia, ordinal linguistic personification in which sequences have personalities, and mirror-touch synesthesia in which seeing touch evokes tactile sensation; synesthesia is generally considered a benign trait rather than a disorder, occurs in a few percent of people and is studied in neuroscience and psychology.
What it is for: Not applicable; a perceptual trait.
It can be explain forms; relay research; describe experiences; distinguish from related phenomena.
Distinguishing features
Involuntary and automatic
Consistent over time
Many forms
Benign trait
What it looks like
Not a visible object; cross-sensory experiences.
Physical character
prevalence: about 4 percent - estimates
forms described: over 60 count
consistency test: test-retest of associations note - standard method
How it is recognised
Cross-activation of senses or concepts
Grapheme-colour, chromesthesia, phoneme-colour, ordinal linguistic personification, mirror-touch synesthesia
Metaphor is linguistic; hallucination lacks a consistent trigger; sensory disorders impair perception
