AB  - Squire and colleagues have proposed that trace and delay eyeblink conditioning 
      are fundamentally different kinds of learning: trace conditioning requires 
      acquisition of a conscious declarative memory for the stimulus contingencies 
      whereas delay conditioning does not. Declarative memory in trace conditioning is 
      thought to generate conditioned responding through the activation of a conscious 
      expectancy for when the unconditioned stimulus (US) is going to occur. Perruchet 
      (1985) has previously shown that in a 50% partial reinforcement design it is 
      possible to dissociate single cue delay eyeblink conditioning from conscious 
      expectancy for the US by examining performance over runs of reinforced and 
      nonreinforced trials. Clark, Manns, and Squire (2001) claim that this 
      dissociation does not occur in trace eyeblink conditioning. In the present 
      experiment we examined the Perruchet effect for short, moderate, and long trace 
      intervals (600, 1000, and 1400 ms) and for the equivalent interstimulus intervals 
      (ISIs) in a delay conditioning procedure. We found evidence for a dissociation of 
      eyeblink CRs and US expectancy over runs regardless of whether there was a delay 
      or a trace arrangement of cues. The reasons for the Perruchet effect are still 
      unclear, but the present data suggest that it does not depend on a separate 
      nondeclarative system of the type proposed by Squire and colleagues.
