Chapter 6 Flashcards
Learning
relatively permanent change in an organism’s behavior from experience or practice.
Associative Learning
How two or more pieces of information are related
Classical conditioning
Learning two stimuli go together
Ex. Scary movies music produces anxiousness when heard
Operant conditioning
Learning a behavior brings a particular outcome
Ex. Studying leads to better grades
Observing
We learn and or change behavior after watching another person.
Modeling
Imitating another’s behavior
Vicarious conditioning
Learning after seeing others being rewarded, or punished, for an action
LTP (Long-term potentiation)
Strengthening of synaptic connections
Who discovered classical conditioning?
Ivan Pavlov, while studying digestion
Behaviorism
School of psychology and theoretical viewpoint that emphasizes the scientific study of observable behaviors, as they pertain to learning
Who founded behaviorism?
John Watson
What is CS?
Conditioned Stimuli
What is UCS?
Unconditioned Stimuli
Extinction of CR (conditioned responses)
Gradual waking and disappearance of the CR as a result of repeated presentation of the CS without the UCS
Spontaneous Recovery
After a rest period, reappearance of an extinguished response when CS is presented.
Generalization
The tendency to make a CR to a stimulus similar to the original CS
Discrimination
Learned ability to distinguish between similar stimuli so that the CR occurs only to the original CS but not to similar stimuli
Cognitive Perspective on Classical Conditioning
Demonstrated that classical conditioning is not just repeated pairing of the CS and the UCS
Cognitive Perspective on Classical Conditioning
Conditioning depends on whether the CS reliable predicts the UCS - this usually means slightly before the UCS
Conditioned Taste Aversion
Development of nausea or an aversive response to a particular taste because that taste was followed by a nauseous reaction, occurring after only one association.
Who discovered taste aversion?
John Garcia
How does it differentiate?
Only needs one pairing, time between CS and UCS can be several hours, particular conditioned stimulus that is used makes a difference in classical conditioning.
Operant Conditioning
- Explains voluntary behaviors
- The consequences of behavior change the probability of that behavior occurrence
What is Thorndike’s Law of Effect
- Behaviors followed by favorable consequences become more likely
- Behaviors followed by unfavorable consequences become less likely
Puzzle Box Experiment
Cat had to press a pedal to escape the box and receive a fish
Operant Conditioning
Learning in which a behavior increases if followed by reinforcement or diminished if followed by punishment
- can shape entirely new behaviors
Operant
A voluntary behavior (action) that brings a consequence.
Reinforcer
Anything that follows a behavior (operant) and increases the likelihood a behavior will occur again (a reward of some kind)
Reinforcement
Reinforcement increases behavior probability
Positive Reinforcement
- behavior followed by a rewarding consequence
- rewarding stimulus is “added”
Negative Reinforcement
- behavior followed by a rewarding consequence
- aversive (unpleasant) stimulus is “removed”
Negative Reinforcement
Avoid or stop an unpleasant condition or consequence (penalty/punishment) Ex. Traffic Tickets, Late Bill Payment
