Primes¶
- Reinforcement
- The schedule is deliberately engineered: escalating-value vouchers with reset-on-relapse create a steep persistence gradient, and the variable "fishbowl" prize draw borrows the variable-ratio structure known from the lab to maximize extinction resistance.
This sourceDescribes the variable-ratio "fishbowl" prize-draw schedule in contingency management.

Petry et al. say their prize-draw schedule was chosen for escalating fixed-ratio features and lower cost via intermittent reinforcement, not for variable-ratio extinction resistance.
“This schedule was chosen because it contains aspects of a fixed ratio schedule that escalates with increasing abstinence... utilizing an intermittent schedule of tangible rewards”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
