Classical Conditioning

\

• Acquisition: process of developing and strengthening a conditioned response through repeated pairings of neutral stimulus with unconditioned stimulus   * more intense US produces stronger / more rapid conditioning (than less intense US)   * more intense NS produces stronger / more rapid conditioning (than less intense NS)
• Extinction: when conditioned response is weakened/eliminated by repeatedly presenting CS alone   * ex: anielle was really scared of cats, so more exposure to declan w no problems helped extinguish that fear
• Spontaneous recovery   * extinguished response can be reacquired rapidly when the CS or NS is once again paired with US   * when paired again, it will take fewer trials to achieve a strong level of conditioning
• Stimulus generalization: tendency for CR to occur in presence of stimulus similar to CS   * ex: Albert or whatever and the bunny ➝ all white things   * meaning of the word is more important than the sound of the word   * like sensitization, but sensitization happens without a conditioning process
• Stimulus discrimination: tendency for a response to be caused more by one stimulus than another
• Higher-Order Conditioning   * basic conditioning: basic reaction to an event, such as a dog salivating at sight of food   * higher-order conditioning: transfer of conditioning to another stimulus through association   * several steps between something occurring and the reaction
• sensory preconditioning: when one stimulus is conditioned as a CS, another previously paired stimulus can also become a CS   * stimulus came first   * ex: toolshed has wasps. i got stung by a wasp and now i’m afraid of wasps, so i’m afraid of the toolshed
