Learning
answer
any relatively permanent change in behavior brought about by experience or patience.
question
Research suggests strongly..
answer
that once people learn something, it is always present somewhere in memory.
question
Maturation
answer
change like an increase in height of the size of the brain
question
Reflex
answer
an unlearned, involuntary response that's not under personal control or choice
question
Stimulus
answer
any object, even, or experience that causes a response
question
Response
answer
the reaction of the organism.
question
In the case of Pavlov's dogs..
answer
-The food is the stimulus -The salivation is the response
question
Classical conditioning
answer
learning to elicit an involuntary, reflex-like response to a stimulus other than the original, natural stimulus that normally produces it
question
Unconditioned stimulus
answer
"unlearned" or "naturally occurring." This is the stimulus that ordinarily leads to the involuntary response. -In Pavlov's case, the food was the unconditioned stimulus
question
Unconditioned response
answer
the automatic and involuntary response to the unconditioned stimulus. Is is unlearned and occurs because of genetic "wiring" in the nervous system. -In Pavlov's, the salivation is the UCR
question
Neutral stimulus
answer
it has no affect on the response
question
Conditioned stimulus
answer
"learned" stimulus. The neutral stimulus becomes this
question
The repeated pairing of a a NS and the UCS is usually called..
answer
acquisition, because the organism is in the process of acquiring learning.
question
An unconditioned stimulus..
answer
is always followed by an unconditioned response
question
A conditioned stimulus..
answer
is always followed by a conditioned response.
question
The CS must..
answer
come before the UCS
question
Stimulus Generalization
answer
the tendency to respond to a stimulus that's only similar to the original conditioned stimulus
question
Extinction
answer
when the conditioned response "dies out"
question
Once people learn something..
answer
it's almost impossible to "unlearn" it.
question
Learning is..
answer
relatively permanent
question
Spontaneous recovery
answer
the conditioned response can briefly reappear when the original CS returns, although the response is usually weak and short-lived.
question
Higher-order conditioning
answer
occurs when a strong conditioned stimulus is paired with a neutral stimulus. The strong CS can actually play the part of a UCS, and the previously neutral stimulus becomes a second conditioned stimulus.
question
Expectancy
answer
created by pairing the tone or its absence with the shock that determined the particular response of the rats.
question
Cognitive perspective
answer
Mental activity of consciously expecting something to occur, an example of an explanation for classical conditioning.
question
Conditioned Emotional Response:
answer
John B. Watson classic experiment with "Little Albert"
question
Conditioned emotional response definition
answer
learning of phobias is a good example of classical conditioning. Some of the easiest forms to accomplish and our lives are full of them.
question
Vicarious conditioning
answer
simply watching someone else respond to a stimulus in this process
question
Conditioned taste aversion
answer
nausea to any liquid or food they swallow up to 6 hours before
question
Fear is a..
answer
natural emotional response that has ties to survival.
question
Operant conditioning
answer
based on the research of Edward L. Throndike and B.F. Skinner
question
Edward L. Thorndike
answer
was one of the first researchers to explore and attempt to outline the laws of learning voluntary responses
question
Law of effect
answer
Thorndike developed this. If an action is followed by a pleasurable consequence, it will tend to be repeated. If it's responded by an unpleasant consequence, it will tend to not be repeated.
question
B.F. Skinner
answer
was the behaviorist who assumed leadership of the field after John Watson
question
Voluntary behavior, for Skinner..
answer
is operant behavior
question
Operant conditioning..
answer
"If I do this, what's in it for me?"
question
Reinforcers
answer
items or events, that hen following a response will strengthen it.
question
Primary reinforcer
answer
any kind of food, liquid, or touch are examples.
question
Secondary reinforcer
answer
such as money
question
Positive reinforcement
answer
the reinforcement of a response by the addition or experience of a pleasurable consequence such as a reward or pat on the back.
question
Negative reinforcement
answer
following a response with the removal or escape from something unpleasant will also increase the likelihood of that response being repeated.
question
Partial reinforcement effect
answer
a response that is reinforced after some, but not all, correct responses. Will be more resistant.
question
Continuous reinforcement
answer
a reinforcer for each and ever correct response. Doesn't work as well as partial reinforcement effect.
question
Interval schedule
answer
when the timing of the response is more important
question
Ratio schedule
answer
when it is the number of responses that are important
question
Fixed interval schedule of reinforcement
answer
in which a reinforcer is received after a certain, fixed interval of time has passed.
question
A fixed internal schedule does not..
answer
produce a fast rate of responding
question
Variable interval schedule of reinforcement
answer
Pop quizzes are an example.
question
Fixed ratio schedule of reinforcement
answer
the number of responses required to receive each reinforcer will always be the same number.
question
Variable ratio schedule of reinforcement
answer
is one in which the number of responses changes from one trial to the next.
question
Delaying reinforcement tends to...
answer
not work, especially when dealing with animals and small children.
question
Punishment
answer
opposite of reinforcement. It's any event or stimulus that, when following a response, causes the response to be less likely to happen again.
question
Punishment weakens..
answer
response
question
Reinforcement (no matter positive or negative) strengthens..
answer
response
question
Positive reinforcement...
answer
the reinforcement of a response by the addition or experience of a pleasurable consequence
question
Negative reinforcement...
answer
the reinforcement of a response by the removal or escape from an unpleasant consequence.
question
Negative reinforcement strengthens a response but..
answer
punishment weakens a response
question
Punishment by application
answer
occurs when something unpleasant is added to the situation or applied.
question
Punishment by removal
answer
behavior is punished by the removal of something pleasurable or desired after the behavior occurs. -Example: grounding
question
Children who are spanked..
answer
are more likely to use aggression
question
Discriminative stimulus
answer
any stimulus that provides an organism with a cue for making a certain response in order to obtain reinforcement. -Example: a police car is a discriminative stimulus for slowing down
question
Extinction:
answer
classical conditioning involves the removal of the UCS, the unconditioned stimulus that eventually acts as a reinforcer
question
Spontaneous recovery
answer
the recurrence of a conditioned response after extinction
question
Shaping
answer
in which small steps toward some ultimate goal are reinforced until the goal itself it reached. -Example: teaching animals tricks
question
Successive approximation
answer
the goal is achieved by reinforcing each small step
question
Instinctive drift
answer
the Brelands called this tendency to reverty to genetically controlled patterns

the use of tokens to modify behavior.

Applied behavior analysis
answer
the modern term for a form of behavior modification that uses both analysis of current behavior and behavioral techniques to mold a desired behavior or response.
question
Biofedback
answer
the traditional term used to describe this kind of biological feedback of information, and through its use many problems can be relieved or controlled
question
Neurofeedback
answer
involved trying to change brain-wave activity
question
Cognition
answer
the mental events that take place inside a person's mind while behaving, began to dominate experimental psychology.
question
Latent learning
answer
the idea that learning could happen without reinforcement and then later affect behavior, was not something traditional operant conditioning could explain.
question

answer
smart chimp that used insight to collect food
question
Insight
