Learning Flashcards
Learned Behavior
Involve Change and Experience
Ivan Pavlov
Who: Russian physiologist
Contribution: Discovered classical conditioning through digestion studies in dogs.
Associative Learning
Organism makes connection b/w stimuli/event that happen in the environment
Unlearned Behaviors
Behaviors that do not have to be learned; organisms are born with them.
Function: Help organisms adapt to their environment.
Innate Behavior: Reflex
Automatic motor or neural reactions to specific stimuli (e.g., knee jerk, pupil contraction in bright light, startle reflex, righting reflex, rooting).
Simpler than instincts.
Innate Behavior: Instincts
Complex innate behaviors triggered by a broader range of events.
Involve the whole organism and higher brain centers (e.g., mating, migration, aging, change of seasons).
Classical Conditioning
Learning to make a reflex response to a stimulus other than the original natural stimulus.
Key Concept: A different stimulus can be trained to trigger the same reflex.
Acquisition
The process of acquiring learning through repeated pairing of the neutral stimulus (NS) and the unconditioned stimulus (UCS).
Key Points:
-NS must precede UCS.
-NS and UCS must be closely timed (ideally within seconds).
-Multiple pairings are needed for conditioning.
-NS/CS should stand out from competing stimuli (e.g., metronome, clicker).
Stimulus Generalization
Response to stimuli similar to the original conditioned stimulus (CS).
Example:
Dentist drill → anxiety
Coffee grinder → some anxiety
Stimulus Discrimination
Tendency to stop responding to a similar stimulus that is not paired with the unconditioned stimulus (UCS).
Example:
Dogs learn to differentiate between two ticking sounds when only one is paired with food.
Extinction
The disappearance or weakening of a learned response.
In Classical Conditioning: Occurs when the unconditioned stimulus (US) is removed or absent (e.g., no food after the bell).
In Operant Conditioning: Happens with the removal of a reinforcer.
Spontaneous Recovery
Reappearance of a learned response after extinction.
Characteristics: Typically weaker than the original conditioned response (CR).
Factors Influencing Recovery: Depends on cue salience and the individual’s state.
Higher-Order Conditioning
A strong conditioned stimulus (CS) is paired with a new neutral stimulus.
Example: Ticking (CS) paired with finger snapping (neutral stimulus).
Outcome: The new neutral stimulus becomes a second conditioned stimulus.
Cue Similarity
Definition: Cue similarity refers to how similar cues can elicit a conditioned response.
Importance: Similar cues can influence the strength and likelihood of a conditioned response.
Conditioned Emotional Response (CER)
An emotional response that is classically conditioned to occur in response to learned stimuli.
Examples:
Fear of dogs
Emotional reaction upon seeing an attractive person
Note: Some CERs can lead to phobias, which are irrational fear responses.
Vicarious Emotional Conditioning
Classical conditioning of a reflex response or emotion occurs by observing another person’s reaction.
Example: Learning a friend’s fear response to bees.
Operant Implications:
-If the observed behavior is rewarded, modeling of that behavior is more likely.
-A perception of the moral rightness of the behavior is likely to form.
Taste Aversion
A learned aversion to a specific taste that occurs after one negative experience (e.g., nausea).
Concept: Biological Preparedness
Why Classical Conditioning Works - “Now”
Cognitive Perspective
Definition: Modern theory suggesting that the conditioned stimulus (CS) provides information or an expectancy about the occurrence of the unconditioned stimulus (US).
Why Classical Conditioning Works - “Then”
Stimulus Substitution
Definition: The original theory by Pavlov that the conditioned stimulus (CS) acts as a substitute for the unconditioned stimulus (US) after being paired closely together.
B.F. Skinner and Operant Conditioning
Background: Skinner was a behaviorist focused on observable, measurable behavior.
Term Origin: Coined the term “operant conditioning.”
Definition: Operant refers to any voluntary behavior.
Principle: Learning is influenced by the consequences that follow a response.
Operant Conditioning
Learning of voluntary behavior through the effects of pleasant and unpleasant consequences to responses.
Key Point: Involves active choice and decision-making based on rewards or punishments.
Thorndike’s Law of Effect
Behaviors followed by pleasurable consequences are likely to be repeated, while behaviors followed by unpleasant consequences are less likely to be repeated.
Key Point: This principle underlies the foundation of operant conditioning.
Primary Reinforcer
A reinforcer that is naturally reinforcing by fulfilling a basic biological need (e.g., hunger, thirst, touch).
Reinforcement
Any event or stimulus that, when following a response, increases the likelihood that the response will occur again.
