Chapter 5: Learning

Classical conditioning:
* The three stages of conditioning:
    Stage 1: Before conditioning
      -Unconditioned Response: behavior of interest
      -Unconditioned Stimulus: event that “naturally” causes the behavior of interest
      -Neutral Stimulus: event that does not “naturally” cause the behavior of interest

    Stage 2: Conditioning
      -Neutral stimulus is consistently presented many times with the unconditioned stimulus

    Stage 3: After conditioning
      -Over time, the behavior of interest appears as soon as the neutral stimulus is presented
      -The unconditioned response became a conditioned response
      -The neutral stimulus became the conditioned stimulus.

* In stage 2, when is the presentation of the neutral stimulus most effective for rapid conditioning?
-Neutral stimulus starts before, and overlaps, the presentation of the unconditioned stimulus.

* After conditioning, will the conditioned stimulus cause the conditioned response forever?
-Extinction: Over time, the conditioned stimulus loses its predictive value if it is not followed by the unconditioned stimulus.
       -Reconditioning happens if the conditioned and unconditioned stimuli are presented together again.
       -Spontaneous Recovery to the unconditioned stimulus happens after a rest period.

* What type of information is important in predicting events?
-Most plausible cause:
        -We often associate sickness with what we ingested
        -We often associate being hurt with external events

-Familiarity: The more familiar a neutral stimulus, the more difficult it will be to make it a conditioned stimulus.

-Similarity: Through the process of generalization, the more similar a neutral stimulus is to the conditioned stimulus, the more likely it is to become a conditioned stimulus itself.

-Context: Through the process of discrimination, certain conditioned stimuli can lose their predictive powers in certain situations.
