Primary Assay — Goldfish
Color Discrimination
Carassius auratus
Goldfish discriminate hues across the visible spectrum and into UV via four cone classes. Two-choice operant assays reveal teleost color cognition.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Carassius auratus.
| Parameter | Unit | Description |
|---|---|---|
| Discrimination accuracy | % | Correct hue choice |
| JND across spectrum | nm | Wavelength resolution |
| Trials to criterion | count | Acquisition |
| Generalization gradient | slope | Across novel hues |
