Ch. 7
Observational learning
The process of watching how others behave and in result, learn from example
Stimulus Generalization
The tendency for stimuli similar to those used during learning (CS) to elicit a reaction similar to the learned response. (dog reacting to different tones for food instead of just one)
Second-order Conditioning
When a CS-US relationship is well established, the CS can be paired with a second, neutral stimulus until that stimulus elicits the same conditioned response. -conditioned stimulus can be weakened -spontaneous recovery -repeated trials can extinct CR
Skinner
Who is famous for the Baby Box?
Punishment
___ is not the most effective way to teach
Phobias
____ develop due to a neutral stimuli that were not initially the fearful stimuli, but occurred simultaneously
mirror neurons
____ explains why we are a social species.
Inborn fear
a fear you were born with
Vicarious Conditioning
a form of learning in which the learner acquires a conditioned response merely by observing another participant being conditioned
Partial reinforcement
a learning condition in which only some of the organism's responses are reinforced.
Interval schedule
a pattern of delivering reinforcements only after a certain amount of time has passed.
Ratio Schedule
a pattern of delivering reinforcements only after a certain number of responses.
dishabituation
a previously predictable stimulus changes, causing the organism to renew its attention to the stimulus -increase in responsiveness -want to pay attention/reassess
fixed ratio
a reinforcement every fixed amount of times you complete the task (every 5th turn)
fixed interval
a reinforcement every fixed amount time (every 5 minutes)
Conditioned response
a response elicited by an initially neutral stimulus-the conditioned stimulus- after it has been paired repeatedly with an unconditioned stimulus. (response due to learned association) ex. because the bell is related to food -> triggers salivation
Unconditioned Response
a response elicited by an unconditioned stimulus without prior training (automatic response) ex. salivation
Positive Reinforcement
a response follows by a rewarding stimulus ex. press lever, get food
Imitation is...
a result of observational learning
Unconditioned Stimulus
a stimulus that reliably triggers a particular response without prior training ex. food
discriminate
an aspect of learning in which the organism learns to respond differently to stimuli that have been associated with a US (or reinforcement), and stimuli that have not
Discriminate
an aspect of learning in which the organism learns to respond differently to stimuli that have been associated with a US (or reinforcement), and stimuli that have not.
Reinforcer
anything that an organism will work to achieve/succeed
Our most basic form of learning is...
classical conditioning
Habituation
decline in response to stimuli that have become familiar through repeated exposure -technique for learning
Thorndike
formulated the Law of Effect using a puzzle box and a cat (pressed lever, get food)
The most basic form of learning is.....
habituation
classical conditioning explains...
how irrational phobias develop
Classical conditioning
learning by the association between one stimulus and another -before conditioning (US+UR) -after conditioning (CS+CR)
______ is problematic in kids with autism
mirror neurons
Mirror neurons
neurons that fire whenever an object performs an action, and whenever the object watches another thing performing the same action. -a motor neuron in the motor cortex
habituation studies measure...
perceptual and visual abilites
Law of Effect
performance is strengthened if it's followed by a reward and weakened if it's not. -we do things because we are reinforced
classical conditioning is linked to ...
phobias
Variable schedule
providing a reinforcement on AVERAGE (time or number of times)
Instrumental Conditioning (operant conditioning)
reinforcement after appropriate response (uses a reward system). -refers to learning of behaviors under voluntary control.
Variable Interval
reinforcement on average amount of time (minutes, seconds)
variable ratio
reinforcement on average number of times (every 5, every 7)
Negative Reinforcement
response followed by the removal of an aversive/unwanted stimulus ex. removal of shock
Schedule of Reinforcement
the rules about how often and under what conditions a response will be reinforced.
Operants
voluntary responses strengthened by reinforcement
Punishment
when a behavior is weakened or decreased due to an aversive/unwanted stimulus being implimented
Albert Bandera
who conducted the Bobo Doll Experiment
Watson
who did studies on "Little Albert" and fears
Insight Learning
"aha" experience -learning occurs when an organism suddenly grasps the solution to a problem and incorporates new and old knowledge.
mirror neurons are linked to...
-empathy -sympathy -imitation
2 inborn fears
-falling -loud noises
What are the 4 things that we have to be able to do to learn by observation?
-have to pay attention -have to retain information -have to be able to reproduce the behavior -have to be motivated
Increasing a respons
-positive reinforcement -negative reinforcement
Systematic Desensitization
-repeated presentation of CS designed to reduce anxiety. -how we treat phobias
Bobo doll experiment
-studied aggression -explains that we learn by watching
Ivan Pavlov
-studied classical conditioning -measured saliva produced in a dog
Kohler's experiment
-studied insight -discovered that animals have insight -chimp sultan
criticisms of bobo doll experiment
-the purpose of the bobo doll -age
VIDEO: Do pigeons have insight?
-yes -pigeon sultan experiment
Escape learning
A type of learning in which an organism acquires a response that decreases or ends some aversive/unwanted stimulus.
Conditioned Stimulus
An initially neutral stimulus that comes to elicit a new response due to pairings with the unconditioned stimulus. ex. ringing of the bell -> related to food
Avoidance Learning
An organism acquires a response that prevents some aversive/unwanted stimulus from occurring
BF Skinner
Behavioral psychologist and inventor who took operant conditioning to the next level -elaborated and defined Thorndike's -studied animals in highly -time vs. behavior (animal and food)
Classical vs. Operant
Classical Operant -stimulus precedes -stimulus follows response and the response and strengthens it elicits it -response is a reflex -response is voluntary and emitted and elicited -learning as a result -learning as a result of of association consequences -Pavlov & Watson -Thorndike & Skinner
Punishment
Decreasing a response
VIDEO QUESTION: what was the video about?
Skinner talks about the schedules of reinforcement -basically saying that people don't control their actions. we act upon reinforcements
