...However, Rescorla (1968) showed that rats did not emit a CR when trials involving the US alone were added to trials where the temporal pairing between US and CS was preserved....

...This phenomenon indicates the onset of overshadowing of the CS by the context, a process commonly thought to rely on competition between potential predictors at the time of conditioning (Rescorla 1968; Rescorla and Wagner 1972)....

...However, Rescorla (1968) himself demonstrated that contiguity alone is not sufficient to explain AL, because additional contingency is required as well....

...A few studies verified that the truly random control produced no discernible evidence of learning (Gamzu & Williams, 1971, 1973; Quinsey & Ayres, 1969; Rescorla, 1968, 1969)....

...Originally, a lack of contingency was defined as equality between two conditional probabilities, p(US|CS) and p(US|noCS), but the calculations were based on fixed time intervals of 2 min (Rescorla, 1968)....

...…in the introduction, there are many instances in which the random control procedure has resulted in learning, but there are also instances in which the random control has resulted in no discernible evidence of learning (Gamzu & Williams, 1971, 1973; Quinsey & Ayres, 1969; Rescorla, 1968, 1969)....
