answer
Bandura's Observational Learning (response = rewarding stimulus presented) (Albert Bandura)
question

answer
classical conditioning
question
Involves applying reinforcement or punishment after a behavior and focuses on strengthening or weakening voluntary behaviors
answer
operant conditioning
question
One of the simplest ways to remember the differences between classical and operant conditioning is to focus on whether the behavior is _____ or ________.
answer
involuntary or voluntary
question
________ conditioning involves making an association between an involuntary response and a stimulus, while operant conditioning is about making an association between a voluntary behavior and a consequence.
answer
Classical
question
In _______ conditioning, the learner is also rewarded with incentives, while classical conditioning involves no such enticements.
answer
operant
question
________ conditioning is passive on the part of the learner.
answer
classical
question
_______ conditioning requires the learner to actively participate and perform some type of action in order to be rewarded or punished.
answer
operant
question
In a classroom setting, a teacher might utilize _______ conditioning by offering tokens as rewards for good behavior.
answer
operant
question
In animal training, a trainer might utilize ________ conditioning by repeatedly pairing the sound of a clicker with the taste of food. Eventually, the sound of the clicker alone will begin to produce the same response that the taste of food would.
answer
classical
question
occurs when a response is strengthened because it is followed by the presentation of a rewarding stimulus.
answer
positive reinforcement
question
occurs when a response is strengthened because it is followed by the removal of an aversive (unpleasant) stimulus.
answer
negative reinforcement
question
occurs when an event weakens the tendency to make that response
answer
punishment
question
In operant conditioning the ______ _______ occur naturally and do not need to be learned. Examples include things that satisfy basic survival needs such as water, food, sleep, air and sex.
answer
primary reinforcers
question
In operant conditioning, _____ ______refers to a situation in which a stimulus reinforces a behavior after it has been associated with a primary reinforcer.
answer
secondary reinforcement
question
a specific pattern of presentation of reinforcers over time
answer
schedule of reinforcement
question
occurs when every instance of a designated response is reinforced.
answer
continuous reinforcement
question
occurs when a designated response is reinforced only some of the time
answer
intermittent reinforcement
question
Reinforcement schedules come in many varieties, but four particular types of intermittent schedules have attracted the most interest:
answer
fixed-ratio, variable-ratio, fixed interval, and variable-interval
question
the reinforcer is given after a fixed number of nonreinforced responses ex - a rat is reinforced for every tenth lever press ex - a salemean is given a bonus for every fourth gym membership sold
answer
fixed-ratio schedule
question
the reinforcer is given after a variable number of nonreinforced responses ex - a slot machine in a casino pays off once every six tries on average. the number of nonwinning responses payoffs varies greatly from one time to the next
answer
variable-ratio schedule
question
the reinforcer is given for the first response that occurs after a fixed time interval has elapsed ex- students can earn grades (let's assume the grades are reinforcing) by taking exams every three weeks
answer
fixed-interval schedule
question
the interval length varies around a predetermined average ex- a person repeatedly dials a busy phone number (getting through is the reinforcer)
answer
variable-interval schedule
question
True or False Allowing a rat to press a lever to turn off a mild shock is an example of negative reinforcement.
answer
True
question
True or False A stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus in classical conditioning.
answer
True
question
True or False The fact that the principles of conditioning are routinely applied in homes, businesses, schools, and factories indicates that psychology evolves in a sociocultural context.
answer
True
question
True or False Stimulus discrimination occurs when an organism has learned a response to a specific stimulus and does NOT respond in the same way to new stimuli that are similar to the original stimulus.
answer
True
question
True or False Concerns about the use of punishment as a disciplinary measure include concerns about side effects including anxiety, anger and resentment
answer
True
question
True or False In positive reinforcement the response is strengthened as a result of the presentation of an unpleasant stimulus.
answer
False
question
True or False B.F. Skinner is associated with operant conditioning.
answer
True
question
True or False Pavlov did his research on cats.
answer
False
question
True or False The extinction stage refers to the first stage of learning something.
answer
False
question
True or False Food would be considered a primary reinforcer.
answer
True
question
"Operant conditioning shapes behavior as a sculptor shapes a lump of clay."
answer
B. F. Skinner
question
Who used classical conditioning?
answer
Watson
question
the father of operant conditioning
answer
B. F. Skinner
question
to understand behavior is to look at the causes of an action and its consequences
answer
operant conditioning
question
reinforcement theory is part of the ____ _____
answer
operant theory
question
roughly changing of behavior by the use of reinforcement which is given after the desired response
answer
operant conditioning
question
Skinner identified three types of responses or operant that can follow behavior.
answer
Neutral operants, Reinforcers, Punishers
question
responses from the environment that neither increase nor decrease the probability of a behavior being repeated.
answer
Neutral operants
question
Responses from the environment that increase the probability of a behavior being repeated. These can be either positive or negative.
answer
Reinforcers
question
Responses from the environment that decrease the likelihood of a behavior being repeated, therefore weakening behavior.
answer
Punishers
question
the opposite of reinforcement since it is designed to weaken or eliminate a response rather than increase it.
answer
punishment
question
The removal of an unpleasant reinforcer can also strengthen behavior.
answer
negative reinforcement
question
________ reinforcement strengthens a behavior by providing a consequence an individual finds rewarding.
answer
Positive
question
the inability to remember something you know, accompanied by a feeling that it's just out of reach
answer
tip-of-the-tongue phenomenom
question
stimuli that help gain access to memories -- such as hints related information, or partial recollections
answer
retrieval cues
question
trying to recall an event by putting yourself back in the context in which it occurred to aid retrieval
answer
context cues ex- returning to a childhood home and remembering a flood of memories (going to Vavo's home)
question
The _____ ________happens when our recall of episodic memories becomes less accurate because of post-event information.
answer
misinformation effect
question
an organized cluster of knowledge about a particular object or event abstracted from previous experience with the object or event
answer
schema However, these mental frameworks also cause us to exclude pertinent information to instead focus only on things that confirm our pre-existing beliefs and ideas. Schemas can contribute to stereotypes and make it difficult to retain new information that does not conform to our established ideas about the world.
question
TRUE or FALSE If information really clashes with a schema, it may attract extra attention and deeper processing and thus become more memorable.
answer
TRUE ex - a slot machine in a professor's office
question

question
____ ____ proposes that forgetting occurs because memory traces fade over time
