Classical Conditioning

  • Neutral Stimulus (NS): A stimulus that initially does not elicit any intrinsic response. It becomes associated with the unconditioned stimulus.

  • Unconditioned Stimulus (US): Stimulus that naturally provokes a response without prior learning. Example: Food for a dog.

  • Unconditioned Response (UR): Natural reaction to the unconditioned stimulus. Example: A dog salivates when it sees food.

Key Concepts in Conditioning

  • Conditioned Stimulus (CS): Formerly neutral stimulus that, after being paired with an unconditioned stimulus, gains the ability to elicit a conditioned response. Example: The bell paired with food.

  • Conditioned Response (CR): Learned response to the conditioned stimulus. After conditioning, the dog salivates to the sound of the bell alone.

  • Example of Association: The pairing of the bell with food is akin to how one responds to thunder after seeing lightning; the response to one naturally evokes a reaction to the other.

Processes in Classical Conditioning

  • Pairing: The repeated association of the neutral stimulus with the unconditioned stimulus leads to the development of a conditioned response.

  • Extinction: The diminishing of a conditioned response when the unconditioned stimulus no longer follows the conditioned stimulus. If a dog stops receiving food after the bell, salivation can cease.

  • Spontaneous Recovery: The temporary return of a conditioned response after a rest period, even without retraining.

  • Stimulus Generalization: When similar stimuli produce a similar response. Example: A dog might salivate at different bells, not just the one used in conditioning.

  • Stimulus Discrimination: The ability to differentiate between similar stimuli; the dog only salivates to one particular bell sound.

Taste Aversion and Biological Preparedness

  • Taste Aversion: A learned avoidance of a particular food that has caused illness. It illustrates classical conditioning in real-life scenarios.

  • Example: A personal anecdote about associating a particular meal (Sloppy Joes) with sickness, thus avoiding it forever.

  • Biological Preparedness: The tendency to associate certain stimuli with specific responses due to survival mechanisms. Example: Not consuming certain plants after feeling sick after eating them.

The Little Albert Study

  • Concept: Demonstrated conditioned emotional responses through a child (Little Albert) associating fear with a previously neutral stimulus (a white rat).

  • Ethical Concerns: The study raised questions about the morality of using a child for psychological experiments and the implications of inducing fear.

Operant Conditioning

  • Definition: A learning process where the consequences of a behavior influence its frequency. Responses that yield satisfying consequences are more likely to be repeated.

  • Law of Effect: Proposed by Thorndike; behaviors followed by favorable outcomes are more likely to recur.

B.F. Skinner's Contributions

  • Reinforcement vs. Punishment:

    • Reinforcement: Increases the likelihood of a behavior. Can be positive (adding a favorable stimulus) or negative (removing an unfavorable stimulus).

    • Punishment: Decreases the likelihood of a behavior. Can involve adding an unpleasant stimulus or removing a pleasant one.

      • Example of Positive Reinforcement: Completing homework to avoid chores.

      • Example of Punishment: Extra chores for misbehavior or declaration of having no privileges.

  • Reinforcement Schedules: The effectiveness of reinforcement can vary depending on how it's administered; details not extensively covered in the text.

Practical Considerations in Parenting and Behavior Management

  • Effective Learning: Emphasizing reinforcement for positive actions over punishment for negative behaviors.

  • Consequences:
