Design of Experiments 5 and 6.
Group | Acquisition | Extinction | Reinstatement | Test |
---|---|---|---|---|
Extinguished | A+ | A− | R (LiCl) | A? |
NR (Sal) | ||||
Novel | A+ | A− | R (LiCl) | B? |
NR (Sal) |
Note. A = conditioned flavor, B = novel flavor, + = reinforced, − = nonreinforced. A and B are sucrose and citric acid, counterbalanced. In Experiment 5, the eight conditioning trials were separated by 24 hrs and the interval between reinstatement injections and the test was 3 hrs. In Experiment 6, there was a shorter 5-hr gap between acquisition trials 1-2, 3-4, 5-6, 7-8, and the interval between reinstatement and test was also 5 hrs.
