Term
learning
Definition
relatively permanent process in behavior, which occurs through experience
Term
behaviorism theory of learning
Definition
focuses solely on observable  behavior, discounting mental activity such as thinking, wishing & hoping. described as relatively stable, observable changes in behavior
Term
associative learning
Definition
when a connection is made between two events
Term
conditioning
Definition
process of learning associations
Term
classical condition
Definition
learning associations between 2 stimuli, learn to anticipate events in result
Term
operant conditioning
Definition
learning association between a behavior and a consequence, thus increase rewarding behavior and decrease punishable behavior
Term
observational learning
Definition
learning by observing and imitating
Term
classical conditioning definition
Definition
neutral stimuli becomes associated w/ a meaningful stimulus and has similar responces
Term
uncondition stimulus UCS
Definition
stimulus produces a responce without prior learning (salivating dog in Pavlov's experiment for example)
Term
unconditional responce UCR
Definition
unlearned response that is automatically caused by the UCS
Term
conditional stimulus
Definition
previously neutral stimulus that eventually has conditioned response after being associated w/ UCS
Term
conditional response CR
Definition
learned responce to CS that occurs after CS-UCS pairing
Term
aquisition (classical conditioning)
Definition
the initial learning of the stimulus/responce link. (neurtal stimulus is being associated with UCS and becoming the CS that produces the CR.
Term
contiguity
Definition
timing, connections in time and space between UCS and CS. (this time needs to be brief)
Term
contingency
Definition
predictability of one stimulus from presense of another
Term
generalization
Definition
tendency of new stimulus that is silimar to original to have the same CS (not having to learn how to drive again after buying a new car)
Term
discrimination
Definition
process of responding to one stimuli and not another.
Term
extinction
Definition
weakening of CR in absense of UCS
Term
sponatenous recovery
Definition
CR can occur after some time even with no further conditioning.
Term
phobia
Definition
an irrational fear (classical conditioning plays a big role)
Term
counterconditioning
Definition
conditiong procedure for weakening CS by associating the "bad" stimulus with a new response (presenting a good stimulus with a bad one)
Term
drugs & conditional learning
Definition
by repeating drug use same time of day/same place/same way, CS is created with the body preparing for the drug (at 6pm, or walking into the drug house). Overdose can occur if the drug is administered in another setting, when the body doesnt prepare itself
Term
classical-respondent behavior form
Definition
behavior occurs automatically in responce to S (stimulus)
Term
operant conditioning
Definition
(BF Skinner) also called instrumental conditioning. Form of associative learning in which the consequences of behavior change the probability of that behavior's occurance.
Term
operant behavior
Definition
voluntary behavior that acts on or "operates" on enviroment & produces rewarding/punishable stimulus.
Term
E.L. Thorndike
Definition
his experiments established the power of consequences in determining voluntary behavior
Term
law of effect
Definition
developed by E.L. Thorndike, that says behaviors followed by positive outcomes are strengthened while behavior followed by negative outcomes is weakened.
Term
S-R Theory
Definition
views of Thorndike, incorrect association weakens bc of consequences of actions
Term
shaping
Definition
rewarding approximates of a desired behavior ( taking baby steps )
Term
reinforcement
Definition
process by which a stimulus or event increases probability of a behavior/event that follows
Term
positive reinforcement
Definition
frequency of a behavior increases bc it's followed by rewarding stimulus (receiving a cookie after cleaning up your room)
Term
negative reinforcement
Definition
frequency of behavior increases bc followed by removal of unpleasant stimulus.
Term
primary reinforcement
Definition
innately satisfying reinforcements such as the basic shelter & fluids
Term
secondary reinforcement
Definition
through experience this reinforcement is learned and conditioned (pat on the back by your boss for a job well done)
Term
token reinforcement
Definition
when an object can be exchanged for some other reinforcer (money for A's, gift cards for B's etc. )
Term
schedules of reinforcement
Definition
timeline that determines when a behavior will be rewarded
Term
fixed-ratio reinf.
Definition
reinforces behavior after a set NUMBER of behaviors
Term
variable-ratio reinf.
Definition
reinforces behavior at average times but on unpredictable basis
Term
interval reinforcement
Definition
determined by TIME elapsed since last behavior was rewarded
Term
fixed-interval reinf.
Definition
reinforces the 1st appropriate behavior after a fixed amount of time elapsed. behavior enacts the closer it gets to "reward" date (politions start kissing babies @ gatherings before elections, you dont see them doing so after they have gained the seat untill it is time to run for that seat again)
Term
variable-interval reinf.
Definition
behavior reinforced after variable amount of time elapsed (pop-quiz, fishing) not knowing when the reward will come
Term
generalization (operant)
Definition
some responce in similar behavior to similar stimulus
Term
discrimination (operant)
Definition
responding to stimulus that signal that a behavior will/will not be reinforced
Term
extinction (operant)
Definition
previously reinforced behavior is no longer reinfoced, there is a decreased tendency to perform that behavior (declining productivity @ work whe no bonus)
Term
positive punishment
Definition
behavior decreases with unpleasant stimulus (smacking a hand)
Term
negative punishment
Definition
behavior decreases bc positive stimulus is removed (no more x-box)
Term
premac principle
Definition
high probability activity can be used to reinforce a low probability activity (when you finish your homework you can play your video game)
Term
observatoional learning
Definition
imitating, copying, modeling someone elses actions and learning them. Bandura's 4 main processes involved are: attention, retention, motion reproduction, enforcement
Term
cognitive factors in learning
Definition
are those that Pavlov (classical) & Skinner (operant) ignored: memory, thinking, planning, etc.
Term
purposive behavior
Definition
E.C. Tolman emphasized idea of purpose of behavior, and much is goal oriented in any organism
Term
Key arguments for purposive behavior
Definition
We acquire expectations from conditioning. Information that CS provides is key to understanding classical conditioning. We form cognitive maps made from expectations about which action is needed to produce a goal, map is mental representation of structure of physical space
Term
latent learning
Definition
-implicit learning- unreinforced learning, not immediately reflected in behavior (rats not finding food, but learning the maze they went through, animals knowing their surroundings when they flee from a predator)
Term
Wolfgang Kohler
Definition
German gestalt psych. - maker of the "ah-ha" moment - pondering and coming to conclusion which he tested by the monkey, fruit and box experiment (monkey had to think about how to get the fruit above his head)
Term
insight learning
Definition
form of learning in which we develop a sudden insight into a problem (lightbulb!)
Term
instinctive drift
Definition
tendency to revert to instinctive behavior that interferes with learning
Term
preparedness
Definition
species-specific bio predispositions that allow learning in certain ways but not others
Term
taste aversion
Definition
bio constrait on learning of person getting sick from a food and not being able to eat it later
Term
John Watson
Definition
author of "Psych. of an infant" : the cry-it-out method, tying hands to the crib, etc. 1928
Term
psychological mindset
Definition
very important in behavor bc it directly connects to reaching a goal
Term
entity theory
Definition
all-or-nothing approach to learning and ability, either you have it or you dont.
Term
incremental theory
Definition
intelligence is something that can increase, be built upon. Failure means you still need to learn
Term
learned helplessness
Definition
phenomenon of learning through experience that outcomes are not controllable
Term
immunosuppression
Definition
(Robert Ader & Nicholas Cohen) decrease in production of antibodies, classical conditioning can produce this, since classical cond. focuses on stimulus ( rats die after associating water with poison)
Term
predictability
Definition
knowledge of upcoming events reduces stress
Term
applied behavior analysis
Definition
application of operant conditioning principles, theory that many emotional and behavioral problems stem from inadequate or wrong responce consequences. ( child continues to break things bc the mother finally pays attention to him)
Term
discriminative stimulus
Definition
only doing correct behavior when a person with authority to reinforce or punish is present
Term
stimulus control
Definition
the person with autority to reinforce/punish
