Experimental Designs

Group Acquisition Extinction Test
Experiment 1
SC-C (P) SP:P → SC: C + (P, C) SC: C − (P, C) SP: P − (P, C)
SC-C SP:P → SC: C + (P, C) SC: C − (C) SP: P − (P, C)
SC Only SP:P → SC: C + (P, C) SC − SP: P − (P, C)
Handle SP:P → SC: C + (P, C) ---- SP: P − (P, C)
Experiment 2
Extinguished SP1:P1 → SC1:C1 +
SP2:P2 → SC2:C2 +		 (P1, P2, C1, C2) SC1:C1 − (C1) SP1:P1 − (P1, P2)
SP2:P2 −
Handle SP1:P1 → SC1:C1 +
SP2:P2 → SC2:C2 +		 (P1, P2, C1, C2) ---- SP1:P1 − (P1, P2)
SP2:P2 −

Note. P and C, and SP and SC refer to procurement and consumption responses, and SDs, respectively. + designates reinforcement, − designates nonreinforcement (extinction), ---- designates handling without exposure to the experimental apparatus. Parentheses indicate which response manipulanda were present in a given phase.
