Primary Assay — Common Cuttlefish
Prawn-in-a-Tube (Delay of Gratification)
Sepia officinalis
The prawn-in-a-tube paradigm demonstrated that cuttlefish can delay gratification — waiting for a preferred prey when an immediate but less-preferred option is available. Maximum wait time and learning across sessions measure self-control capacity.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Sepia officinalis.
| Parameter | Unit | Description |
|---|---|---|
| Maximum wait time | s | Self-control duration |
| Quality vs quantity preference | ratio | Value-based decision |
| Learning across sessions | Δs | Improvement in patience |
