Experimental Designs

Group Acquisition Extinction Test
Experiment 1
 Chain extinction SP:P→SC:C+ (P, C) SP:P→SC:C− (P, C) SC:C− (P, C)
 Procurement extinction SP:P→SC:C+ (P, C) SP:P− (P) SC:C− (P, C)
 Handle SP:P→SC:C+ (P, C) — SC:C− (P, C)
Experiment 2
 SP-P (C) SP:P→SC:C+ (P, C) SP:P− (P, C) SC:C− (P, C)
 SP-P SP:P→SC:C+ (P, C) SP:P− (P) SC:C− (P, C)
 SP only SP:P→SC:C+ (P, C) SP: − SC:C− (P, C)
 Handle SP:P→SC:C+ (P, C) — SC:C− (P, C)
Experiment 3
 Extinguished SP1:P1→SC1:C1+ (P1, C1, P2, C2) SP1:P1− (P1) SC1:C1− (C1, C2)
SP2:P2→SC2:C2+ SC2:C2− (C1, C2)
 Handle SP1:P1→SC1:C1+ (P1, C1, P2, C2) — SC1:C1− (C1, C2)
SP2:P2→SC2:C2+ SC2:C2− (C1, C2)

Note. P and C, and SP and SC refer to procurement and consumption responses, and discriminative stimuli, respectively. + designates reinforcement, − designates nonreinforcement (extinction), — designates handling without exposure to the experimental apparatus. Parentheses indicate which response manipulanda were present.
