...One of these groups (Group 10–0) received all of their reinforcers after a CS presentation—no unsignaled USs were presented during the ITI....

...Support for a performance component comes from numerous studies that document excitatory associations between CS and US following exposure to the random control procedure (Benedict & Ayres, 1972; Kirkpatrick & Church, 2004; Kremer, 1971; Kremer & Kamin, 1971; Papini & Bitterman, 1990) even after excitatory CRs are no longer evident (Delamater, 1996; Rescorla, 2000)....

...There are also many examples of random control procedures in which equal reinforcement rates in the CS and ITI attenuate or prevent acquisition of CRs (Rescorla, 1968; see Papini & Bitterman, 1990, for a review)....

...However, there was a trend toward slowed acquisition in Experiment 1A, and there are other experiments on partial positive contingencies that demonstrated a strong depressive effect of ITI reinforcers (Hallam et al., 1992; Rescorla, 1968)....
