Definition of Learning
Learning is a relatively permanent change in behavior or the potential for behavior that results from experience.
Unconditioned Stimulus (US)
The process begins with a stimulus that naturally and reliably causes some response
A neutral stimulus is a stimulus that does not naturally elicit an unconditioned response in the organism.
Definition of Classical Conditioning
Learning that occurs when a neutral stimulus is repeatedly paired with an unconditioned stimulus; because of the pairing, the neutral stimulus becomes a conditioned stimulus with the same power as the unconditioned stimulus to elicit the response in the organism.
When is Classical Conditioning most effective?
When the neutral stimulus is presented just a few seconds before the unconditioned stimulus
What is Taste Aversion?
A taste aversion is classical conditioning that occurs when an organism pairs the experience of nausea with a certain food and becomes conditioned to feel ill at the sight, smell, or idea of the food.
What makes Taste Aversion a unique form of Classical Conditioning?
It often occurs with only one pairing of the NS/CS and the US
The interval between the NS/CS and the US can be very long.
How is a Classically Conditioned Response extinguished?
A classically conditioned response can be extinguished by no longer following the CS by the UCS.
What is spontaneous recovery?
The reappearance of a conditioned response during and particularly after the extinction process.
What is the law of effect?
The law of effect states that random behaviors that lead to positive consequences will be strengthened and random behaviors that lead to negative consequences will be weakened.
Rewarding a behavior by removing something unpleasant from the environment of the organism.
Positive punishment involves weakening a behavior by adding something unpleasant to the organism's environment
Negative punishment is the weakening of a behavior by removing something pleasant from the organism's environment
Escape conditioning is the process of learning responses that terminates an aversive stimulus.
Avoidance conditioning is the process of learning particular responses that avoid an aversive stimulus.
What needs to happen in order for punishment to be effective?
In order for punishment to be effective it needs to be accompanied with an explanation and reinforcement of appropriate alternative behaviors.
How does extinction occur in operant conditioning?
Extinction in operant conditioning occurs when the behavior is no longer reinforced.
Continuous reinforcement is a schedule of reinforcement in which the organism is rewarded for every instance of the desired response.
A reward is given after a fixed number of responses (this results in the highest rate of responding)
Fixed interval schedules provide reinforcement for the first desired response made after a fixed amount of time has passed. (faster initial response followed by a slower rate of response for a period of time after reward is presented)
Variable interval schedules rewards the first response after an average amount of time has passed.
What is Shaping?
Shaping is using operant conditioning to build a new behavior in an organism by rewarding successive approximations of the desired response.
What is Social Learning?
Social learning is learning through the observation and imitation of other's behavior.
