CH3.1 Associative Learning, Classical and Operant Conditioning Flashcards
CH3.1: Learning
associative learning also happens to humans not just lab animals. T/F?
True
stimulus
anything that triggers a response
What must occur when learning has occured
when a behavioral response changes in response to a stimulus
classical conditioning
Classical conditioning is a type of associative learning that takes advantage of biological, instinctual responses to create associations between two unrelated stimuli.
Classical conditioning works, first and foremost, because some stimuli cause an innate or reflexive physiological response. For example, we reflexively salivate when we smell bread baking in an oven, or we may jump or recoil when we hear a loud noise.
associating a neutral stimulus to an involuntary response
neutral stimuli
sound of bell for dogs before learning. No reason it would have salivated uncontrollablly. Or a song that hasnt been associated with something in your life
causes no response related to the unconditioned pair
ivan pavlov experiment
trained dogs to associated the neutral stimulus (bell) with the unconditioned stimulus of bringing food at feeding time. The dogs would unconditionally (innately) salivate at food. By introducing bell at same time as the food the dogs associated the bell with food. Ultimately the conditioned stimulus of the bell (once neutral) could trigger saliva production without food
unconditioned stimulus
provokes an innate, instinctual response without effort
( unconditioned responses )
when you jump after being starteled
jumping when scared
conditioned stimulus
former neutral stimuli when associated with unconditined stimuli trigger a conditioned response
spike in blood pressure is a newly conditioned response to the former neutral song stimuli (during aquisition)
generalization
responding to a stimuli that resembles another conditioned stimulus
if a conditioned stimulus is a jazz song, responding to a diff jazz song is a generalization
What was the Baby Albert Experiment?
A baby was conditioned to have a fear of white mice
UCR - unconditioned response
UCS - conditioned response
discrimination
discern between similar stimulu
extinction
extinction of a conditioned response between conditioned stimulus and conditioned response
spontaneous recovery
someone is triggered by a conditioned respone again
which occurs after a relationship between conditioned stimuli and response is over (it was seemingly distinct)
reinforcement
encouraging a behavior
positive and negative reinforcement
positive reinforcement - encouraging a behavior, adding a stimulus
negative reinforcement - encouraging a behavior, removing a stimulus
operant conditioning
Operant conditioning, sometimes referred to as instrumental conditioning, is a method of learning that uses rewards and punishment to modify behavior. Through operant conditioning, behavior that is rewarded is likely to be repeated, and behavior that is punished will rarely occur.
Operant conditioning is associated with B. F. Skinner, who is considered one of the founders of behaviorism, the theory that all behaviors are conditioned
punishment in operat conditioning
punishment is any change in a human or animal’s surroundings which, occurring after a given behavior or response, reduces the likelihood of that behavior occurring again in the future.
adding - makes it positive punishment
scolding a kid after cursing
removing - makes it negative punishment
removing a cell phone
Escaping and avoiding in operant conditioning
Escape learning describes a situation where the animal experiences the unpleasant stimulus and, in response, displays the desired operant behavior in order to trigger the removal of the stimulus.
avoidance learning occurs when the animal displays the desired behavior in anticipation of the unpleasant stimulus, thereby avoiding the unpleasant stimulus.
(often develops with multiple expierences of escape learning)
examples of reinforcement schedule
fixed ratio - child recieved a reward after cleaning a certain number of times (#)
continuous reinforcement -fixed ratio schedule where behavior is rewarded EVERY time it is performed
fixed interval - child recieved a reward after cleaning after period of (TIME)
variable ratio - child recieves a reward after # of cleaning dishes after varying number (she cant be sure). But overal average is consistent (ex, 2, 4, 8, 6)
variable interval - child recieves a reward after a random period of time (1 day, 2 weeks)
which reinforcement schedule is the most addictive?
variable schedules are most resistant to extinction
fixed ratio is less addictive
variable ratio is best, then variable interval
Very Rapid and Very Resistant to extinction
VR for Variable Ratio
latent learning
learning that reveals itself once a reward is introduced
incentivized to get good grades for a reward offered
problem solving
apply knowledge learned
biological prepardness
how inclined an animal is to learn a behavior necessary for survival
(occurs via predisposition)
a bird needs to peck when searchign for food, rewarding food in response to pecking works well for learning a task
instinctive/instinctual drift
reverting to an innate behavior
trained dog bark at intruders
