chapter test 5 6 & 7 Flashcards
Behavior causation
ultimate causes
(evolutionary history); (learning history)
proximate causes
(current stimuli) ; (CNS)
Proximate causes
close in time to behavior (stimulus)
ultimate causes
distant in time
(learning history)
two types of learning histories
pavlovian conditioning
operant conditioning
learning
relatively permanent changes in environment behavior relations to certain types of experiences.
classical conditioning is….
the conditioning of reflexes
two (or more) stimuli are paired
NS—–association— + –> UR
Any behavior that is followed by pleasant is likely to be repeated, and any behavior followed by unpleasant consequences is likely to be stopped
the law of Effect (Thorndike’s Law)
The Law of Effect
Behavior is determines its consequences
Thorndikes experiment is can be regarded as a….
discrete trials
trial & error vs trial & success
B.F Skinner
Operant conditioning
free operant experiment—-measuring behavior over time in restricted environment
two term contingency operant conditioning
R——————–S
Response——–Stimulus (consequence)
operant behavior
operates on the environment, changes the environment, and is changed as a result of the environment
environment
all stimuli that affect behavior at any given moment
a stimulus that follows a response and increases the probability of similar responses under similar circumstances
reinforcement procedure and process
reinforcement (procedure and process)
a stimulus change follows a response and increases the probability of similar responses under similar circumstances
the procedure of reinforcement…
Stimulus change follows a response
the process of reinforcement
increases the probability of similar responses under similar circumstances
one instance of behavior
response
response
one instance of behavior
increases the probability (rate or frequency, duration, magnitude etc), of similar responses (response class)
reinforcement process
the reinforcer is added after the response (+)
positive reinforcement
reinforcer is subtracted after the response (-)
negative reinforcement
three characteristics to be called reinforcement
the behavior must be a consequence
the behavior must increase in strength
the consequence must be the reason it increases in strength
negative reinforcement is also called…
escape learning
avoidance learning
when the aversive stimulus is present and you do something to get rid of it
escape learning
when the aversive stimulus is not present yet, and you do something to avoid it
avoidance learning

3 practical advantages of conditioned (or generalized) reinforcers
satiation doesn’t occur
easier to reinforce immediately
less disruptive than primary reinforcers
events that naturally follow a response
are usually not deliberately mediated by other individuals
automatic reinforcers
variables that affect operant conditioning
contingency
temporal contiguity
reinforcer magnitude
motivating operations
all things equal, the greater the _____________between responses and their consequences, the quicker and stronger the conditioning
contingency
temporal contiguity
all things equal, the greater ___________, the quicker and stronger the conditioning (reinforcer characteristics)
reinforcer magnitude
all things equal, the lower the ____________, the quicker and stronger the conditioning (behavior characteristics)
response effort
operates on the environment, changes the environment, and is changed as a result
operant behavior
reinforcer
increases the probability of similar responses under similar circumstances
reinforcement
a stimulus change following a response with a consequence that results in an increase in the probability of similar responses under similar circumstances
Conditioned reinforcers- Depends on pairing with primary reinforcers
generalized conditioned reinforcers - depend on pairing with many other reinforcers.
conditioned (secondary) reinforcers vs generalized conditioned reinforcers
_______ is an equal opportunity consequence

motivating operations
establishing operations
–alter the effectiveness of a reinforcer
—evoke behavior that has produced that reinforcer
3 term contingency motivating operations
EO—-R—–S(R+)
EO—-R—–S(R-)
(EO) Establishing operations
alter the effectiveness of a reinforcer
evoke behavior that has produced that reinforcer
motivating operations
high probability behaviors reinforce low probability behaviors
Premacks’ Principle
considers reinforcers to be behaviors rather than stimuli and that attributes a reinforcer’s effectiveness to its probability relative to other behaviors.
Premack’s relative value theory
when deprived from engaging in a behavior below the baseline, engaging in it back to baseline becomes reinforcing to other behaviors
response-deprivation theory
selection by consequences
behavior like species evolves
reinforcement is like natural selection
Behavior evolves over time
behavior is inherently variable
Environment selects behavior
Behavior retention
a procedure
the differential reinforcement of successive approximation towards a final or target behavior
shaping
shaping:
the differential reinforcement of (2 words)__________ towards or target behavior
successive approximation
events that follow spontaneously from a behavior.
Natural reinforcers
events that are provided by someone for the purpose of modifying behavior.
Contrived reinforcers
the degree of correlation between a behavior and its consequence
Contingency
A term used to refer to the strength of a reinforced behavior.
Behavioral momentum
the gap in time between a behavior and its reinforcing consequence
Temporal contiguity
anything that changes the effectiveness of a con- sequence
Motivating operation
The reward center of the brain, in particular, an area in the septal region running from the middle of the brain to the frontal cortex where dopamine is the most important neurotransmitter
Reward pathway/dopamine
attributes a reinforcer’s effectiveness to the reduction of a drive.
Hull’s drive reduction theory
High-probability behavior reinforces low-probability behavior.
Premack principle
behavior becomes reinforcing when the individual is prevented from engaging in the behavior at its normal frequency.
Response deprivation theory
the reinforcement of successive approximations of a target (desired) behavior
Shaping
the process of reinforcing each of a series of related behaviors to form a behavior chain
Chaining
procedure of breaking a task down into its component elements
Task analysis
begin chaining by reinforcing performance of the first link in the chain
Forward chaining
begin chaining with the last link in the chain and work backward toward the first component (link)
Backward chaining
A series of related behaviors, the last of which produces reinforcement
Behavior chain –
a situation in which reinforcement is available but the behavior necessary to produce it is not
Problem
the response that produces reinforcement
solution
a sudden appearance of the solution (in the mind?)
Insight
novelty
Common feature (of creativity)
Common feature (of creativity)
novelty
any behavior that occurs repeatedly even though it does not produce the reinforcers that maintain it
Superstitious behavior
The tendency to give up on a problem as a result of previous exposure to insoluble problems
Learned helplessness
The tendency to persist at a problem as a result of previous reinforcement of persistence at difficult problems
Learned industriousness
a procedure in which a sequence of responses that make up a more complex chain is reinforced
chaining
a series of responses that occur consecutively
behavior chain
Behavior chain example chart
conditioned reinforcement S(D)——R—->S(r+)
Unconditioned reinforcement
S(D)——-R——–S(R+)
Chaining
- construct a task analysis (TA): breakdown all steps of behavior chain
- reinforce one response in the chain at a time until it occurs, then reinforce when two responses occur, then when three
Two chaining procedures
—forward chaining
—backward chaining
when there is a reinforcer available but no behavior available to produce the reinforcer
problem
the response that produces the reinforcement
solution
the use of imaginations or orignal ideas
reification–making something abstract concrete or real
creativity
randomness (a dimension of behavior)–can be reinforced
novelty
based on the definition of (reinforcement),
why does it seem absurd that reinforcement can increase novel behavior?
similarity is random
as acquisition of behavior
Most people use the term learning
changes in which no new behavior occurs
changes in the pattern of behavior
Learning includes
rules describing the contingency between behavior and reinforcement
Schedule of reinforcement
distinctive patterns of behavior (produced by different schedules)
Schedule effects
a behavior is reinforced every time it occurs (or every response produces a reinforcer)
Continuous schedule (of reinforcement
reinforcement occurs for some responses but not others.
Intermittent schedule
Four simple schedules of reinforcement
FR - Fixed Ratio
VR - variable ratio
FI - Fixed interval
VI - variable interval
reinforcement occurs after a set (or fixed) number of responses.
Fixed ratio
reinforcement occurs after an average number of responses
Variable ratio
reinforcement occurs after the first response after a set (or fixed) amount of time.
Fixed interval
a pause after reinforcement
Post-reinforcement pause
reinforcement occurs after the first response after an average amount of time.
Variable interval
the rate at which behavior occurs once it has resumed following reinforcement
Run rate
reinforcement is withheld from a previously reinforced behavior (or a schedule which no responses are reinforced)
Extinction
a sudden increase in the response dimensions of a behavior when reinforcement is withheld
Extinction burst –
the reappearance of previously reinforced behavior
Resurgence
the sudden reappearance of behavior following extinction and a period of time
