| Classical Conditioning | Operant Conditioning | |
|---|---|---|
| Biological predispositions | Natural predispositions constrain what stimuli and responses can easily be associated. | Organisms most easily learn behaviors similar to their natural behaviors; unnatural behaviors instinctively drift back toward natural ones. |
| Cognitive processes | Organisms develop expectation that CS signals the arrival of US. | Organisms develop expectation that a response will be reinforced or punished; they also exhibit latent learning, without reinforcement. |
