[ Framework Metric ]
NTR: Neurocognitive Transfer Risk.
A risk score for fragile object-to-action transfer across cognitive profiles.
Definition
NTR measures how fragile the transfer is from visible referent to intended action, using AAC-informed pictogram reading rules.
Core Idea
Recognition is not transfer.
Recognizing a symbol does not imply successful communication of the intended meaning or action.
[ How To Read It ]
What The Metric Measures.
The reading applies to the submitted pictogram, expected message, user group, and evidence window.
Whether a user can move from seeing the object to understanding the action.
How abstract, legacy, indirect, or convention-heavy the mapping is.
Whether labels or contextual cues are needed for safer communication.
High Reading
A high NTR means recognition of the visible object does not reliably produce the intended action meaning.
Low Reading
A low NTR means the visible referent, action mapping, and support cues make transfer more direct.
[ Limits ]
What It Does Not Claim.
NTR estimates transfer risk; it does not diagnose users.
NTR does not replace AAC specialist review or user testing.
NTR depends on the submitted context and expected user group.
[ Examples ]
How It Appears In Reports.
A storage object used as an interface action can have high NTR when the action depends on learned convention.
A concrete object with a visible, direct action cue can reduce NTR.
