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