Correlational Opponent Processing would be a good explanation for the effect. Any stimulus temporarily creates its anti-wavelet filter for that future stimulus. This then is a stimulus specific latent inhibition. In the case of schizophrenics who would have timing or Paul trap frequency problems information could not be stored in a gaussian anti-wavelet filter areas due to brain organization. For example exposure to a spin disk does not result in an opponent motion aftereffect when the disk is suddenly stopped. >From a Correlational Opponent Processing perspective classical and operant conditions are special examples under a gobal umbrella of pure associationism. Consider a wavelet phase shift of changing the sound stimuli of a ringing bell to a classically conditioning response of saliva. By shifting the sound frequency some classical conditioning is observed even though the individual has never experience the new stimulus. Such a stimulus is congruent at some probability level and proportional activates the stored wavelet filter. Notice the activation can not be at the same area of the brain because the brain is a global system. The slight change in wavelet interference patterns results in a response of saliva being less and chemically different.
