Term
|
Definition
Permanent change in behavior due to experience |
|
|
Term
|
Definition
Previously neutral stimulus acquires ability to produce a response after it has been associated with a stimulus that already produces the response |
|
|
Term
|
Definition
Process by which behavior is changed by its consequences
Repeating positive behaviors, stopping negative behaviors
Voluntary due to environment
Responding decreases once reinforcement stops |
|
|
Term
|
Definition
Learning by observing others and imitating
Starts right after birth
Cognitive process
No reinforcement or punishment
|
|
|
Term
|
Definition
Process of learning based on associations |
|
|
Term
|
Definition
View that psychology should:
1) Be and objective science that 2) studies behavior without reference to mental processes
Most researchers believe 1 but not 2 |
|
|
Term
|
Definition
Something that naturally and automatically triggers the unlearned
Ex: Meat Powder |
|
|
Term
|
Definition
Unlearned/Automatic response to the unconditioned stimulus
Ex: Salvation to meat powder |
|
|
Term
|
Definition
Previously neutral stimulus that becomes associated with the unconditioned stimulus so that it has the name unconditioned response
Ex: Bell |
|
|
Term
|
Definition
Learned response to the conditioned stimulus
Ex: Salivating to the bell |
|
|
Term
|
Definition
Process of conditioning; pairing the neutral stimulus with the unconditioned stimulus until it causes the same response
Then the neutral stimulus becomes the conditioned stimulus
Pairing works best if the unconditioned stimulus occurs right after the conditioned stimulus |
|
|
Term
|
Definition
Getting rid of conditioned response by giving the conditioned stimulus without the unconditioned stimulus repeatedly
Causes the conditioned response to be forgotten |
|
|
Term
|
Definition
The reappearance of an extinguished response following a rest period |
|
|
Term
|
Definition
The tendency to respond to stimuli that are similar to a conditioned stimulus
Ex: Crying --> Attention then learn to cry in front of other people in hopes of attention
Being attacked by a dog --> Being afraid of all dogs |
|
|
Term
|
Definition
Learn to make response in presence of one stimulus but not another
Ex: Phone ringing you pick it up, if its not ringing you won't answer
If you yell at a kid for running by the pool, they may still run by the pool when you're not around to yell
|
|
|
Term
|
Definition
Biological predisposition to make particular associations
Something things are easier to classical condition than others |
|
|
Term
Conditioned taste aversion |
|
Definition
Avoid foods that previously made you ill |
|
|
Term
Alzheimer's and Classical conditioning |
|
Definition
People who might develop alzheimer's later in life will show problems with classical conditioning before they show symptoms of the disease
Won't blink when they hear tones |
|
|
Term
Chemotherapy and Classical conditioning |
|
Definition
People undergoing chemotherapy will avoid foods they ate the night before due to taste aversion |
|
|
Term
|
Definition
Operant chamber - Chamber containing a bar or key that an animal can manipulate to obtain a food or water reinforcer
Training animals for food |
|
|
Term
|
Definition
Process of learning behavior through operant conditioning
Systematic reinforcement of gradual improvements toward desired behavior |
|
|
Term
Successive Approximations |
|
Definition
Method of shaping
Reward responses that are ever-closer to the final desired behavior and you ignore all other responses |
|
|
Term
|
Definition
Any stimulus that increases the frequency of/makes stronger the behavior that follows
Works best if the consequence follows the behavior quickly after |
|
|
Term
|
Definition
Add something positive/good/pleasant
Reward
Ex: Getting a hug or receiving a paycheck |
|
|
Term
|
Definition
Remove something negative/bad/unpleasant
Often avoiding or escaping something
Ex: Putting a seatbelt on to stop the beeping |
|
|
Term
|
Definition
An innately reinforcing stimulus such as one that satisfies a biological need
Ex: Get food when hungry, have headache go away |
|
|
Term
|
Definition
Secondary reinforcer
A stimulus that gains its reinforcing power through its associations with a primary reinforcer
Ex: Money, good grades, pleasant tones
Each are linked to a basic reward, money --> food |
|
|
Term
Continuous reinforcement schedule |
|
Definition
Every time a correct behavior occurs, it is rewarded/reinforced
Learning is rapid but extinction is rapid if rewards cease |
|
|
Term
Partial reinforcement schedule |
|
Definition
Not every good behavior is reinforced always
Learning is lower but behavior is much more resistant to extinction
More like real life |
|
|
Term
Partial-reinforcement extinction effect |
|
Definition
It is harder to extinguish behaviors that are partially reinforced (rather than continuously reinforced) because the organism is not used to always being reinforced so it is less noticeable is it is stopped |
|
|
Term
|
Definition
Any stimulus that decreases the frequency of behavior it follows |
|
|
Term
|
Definition
Add something negative/bad/unpleasant as a result of an incorrect behavior
Ex: Spanking, parking ticket |
|
|
Term
|
Definition
Remove something positive/good/pleasant as a result of an incorrect behavior
Ex: Time out from privileges, revoked drivers license |
|
|
Term
|
Definition
1) Punisher is a discriminative stimulus - Only stop behavior in front of the punisher
2) Attention - Punishing may be a reinforcement by giving attention to a child
3) Fear and anxiety - Child may associate fear not only with the undesirable behavior but also with the person who delivered the punishment
4) Modeling - Physical punishment teaches children to solve problems with physically |
|
|
Term
|
Definition
Frontal lobe neurons that fire when performing certain tasks or when observing someone doing the same task
Can't be explained by behaviorists |
|
|
Term
Bandura's Bobo Doll Study |
|
Definition
Kids who watch adults beat up Bobo are more inclined to beat up Bobo given the opportunity
Observational learning
Media can alter attitudes/behaviors
Implications of Observant conditioning -> learning from media
Watching violence -> Increased aggressive behavior |
