Any relatively permanent change in behavior brought about by experience or practice.
answer
Learning
question
Gestalt Contiguity- things that occur close in time to one another are grouped together (rules of language syntax). When one event precedes another, we associate one event with the other (thunder, lightning).
answer
Associative Learning
question
Unconditioned Stimulus: unlearned, innate. Unconditioned Response: automatic, involuntary. Pavlov example: food (UCS) and drooling (UCR). No learning needed for dog to drool when it sees food.
answer
Classical Conditioning (UCS and UCR)
question
Conditioned Stimulus: learned (starts off as neutral). Conditioned Response: learned (not as strong as UCR). Food is paired with a bell: Bell (CS) and drooling (CR).
answer
Classical Conditioning (CS and CR)
question
1. Neutral stimulus needs to come before the UCS. 2. Time between the two stimuli should be close (about half a second to 5 seconds apart is ideal). 3. Pairing needs to occur several times, often many. 4. The CS usually needs to be distinctive or stand out from other competing stimuli.
answer
4 Basic Principles of Acquisition in Classical Conditioning
question
Disappearance of a previously learned behavior when the behavior is not reinforced.
answer
Extinction
question
When an Unconditioned Stimulus does not follow a Conditioned Stimulus, a Conditioned Response starts to decrease, and at some point completely diminishes.
answer
Respondent Extinction
question
Sudden and temporary increase in behavior that was previously reinforced at the beginning of extinction. Can result in aggressive behavior or other attempts to obtain the reinforcer.
answer
Extinction Burst
question
After a rest period, an extinguished Conditioned Response spontaneously recovers.
answer
Spontaneous Recovery
question
Tendency to respond to stimuli similar to CS. What we learn in one specific situation or with one specific stimulus transfers to a different situation. The more similar the new stimulus is to the original CS, the greater the likelihood of generalization. Example: Little Albert
answer
Stimulus Generalization
question
When an organism that has learned a response to a specific stimulus does not respond in the same way to new stimuli that are similar to the original stimulus.
answer
Stimulus Discrimination
question
Classical conditioning term, refers to when a stimulus that was previously neutral (clapping) is paired with a Conditioned Stimulus (bell with food to produce salivating) to produce the same conditioned response as the Conditioned Stimulus.
answer
Higher Order Stimulus
question
Classical conditioning in which the Unconditioned Response is an emotional response (fear). Fear Conditioning- the CS (neutral bell) becomes associated with a fearful CR. May lead to phobias (irrational fear responses).
answer
Conditioned Emotional Response (Learning Phobia)
question
Becoming classically conditioned by watching someone else respond to a stimulus.
answer
Vicarious Conditioning
question
Systematic Desensitization Aversion therapy
answer
Applications of Classical Conditioning
question
Classical conditioning occurred because the Conditioned Stimulus became a substitute for the Unconditioned Stimulus by being paired closely together.
answer
Stimulus Substitution (Pavlov)
question
Modern theory in which classical conditioning is seen to occur because the Conditioned Stimulus provides information or a prediction about the coming of the Unconditioned Stimulus. Tone onset and shock vs. tone ending and shock.
answer
Cognitive Perspective (Rescorla)
question
Changes in the liking of a stimulus that result from pairing that stimulus with other positive or negative stimuli.
answer
Evaluative Conditioning
question
Drug (UCS), user's body attempts to counteract effects of the drug (UCR). Setting (neutral) gets paired with drug (UCS) and setting becoming a CS. Setting (CS) leads to user's body trying to counteract drug (CR).
answer
Classical Conditioning and Drug Overdose
question
CS elicits physiological and behavioral changes that are opposite to/compensate for the drug effects.
answer
What happens when drugs show the development of tolerance?
question
Albert Bandura conducted a study to investigate if social behaviors (aggression) can be acquired by observation and imitation. Children's aggressiveness was monitored before and after being exposed to aggressive behavior. Bandura found that the children exposed to the aggressive model were more likely to act in physically aggressive ways than those who were not exposed to the aggressive model.
answer
Bobo Doll Experiment
question
Attention: Observer must pay attention to the model's behavior and its consequences. Memory: Observer must be able to retain memory of what was done. May not have the occasion to use an observed behavior right away; therefore, must store a mental representation of it (including its steps). Imitation: The learner must be capable of reproducing the model's behavior. Motivation: The learner must have the desire or motivation to perform the behavior.
answer
Observational Learning
question
The learning of voluntary behavior through the effects of pleasant and unpleasant consequences to responses.
answer
Operant Conditioning
question
"Responses that produce a satisfying effect in a particular situation become more likely to occur again in that situation, and responses that produce a discomforting effect become less likely to occur again in that situation."
answer
Thorndike's Law of Effect
question
Any event or stimulus, that when following a response, increases the probability that the response will occur again.
answer
Reinforcement
question
Primary: any reinforcer that is naturally reinforcing by meeting a basic biological need (hunger, thirst, touch). Secondary: any reinforcer that becomes reinforcing after being paired with a primary reinforcer (praise, tokens, gold stars).
answer
Primary Reinforcer vs. Secondary Reinforcer
question
Immediate reinforcement occurs immediately after desired or undesired behavior occurs. This type of reinforcement has the quickest effect in controlling behavior because it forms a stronger relationship between stimulus and response. The longer the delay, the less likely the learning.
answer
Immediate vs. Delayed Reinforcers
question
Reinforcement of a response by the addition or experience of a pleasurable stimulus. Stickers for engaging in boring psychological testing, clicker credit for attendance.
answer
Positive Reinforcement
question
Reinforcement of a response by the removal, escape from, or avoidance of an unpleasant stimulus. Taking aspirin for a headache is negatively reinforced (removal of headache). Using drugs when experiencing withdrawal symptoms. Cleaning a house to get rid of a mess.
answer
Negative Reinforcement
question
Deliver reinforcement immediately after the behavior. Deliver reinforcement continuously after the behavior (at least initially). Reinforce only the desired behavior.
answer
How to Reinforce Successfully
question
Any event or object that, when following a response, makes that response less likely to happen again. Best when applied immediately so that relationship between unwanted behavior and punishment is clear. Should be consistent (always follow though, similar intensity each time). Immediate effect of suppressing behavior (explains negative reinforcement for parent). Does not teach appropriate behavior. Can lead to negative emotions (anxiety).
answer
Punishment
question
Punishment of a response by addition or experiencing of an unpleasant stimulus. Spanking a misbehaving child, getting a speeding ticket.
answer
Punishment by Application (Positive Punishment)
question
Punishment of a response by the removal of a pleasurable stimulus. Putting a child in time out, having to pay a financial penalty for turning in a bill late.
answer
Punishment by Removal (Negative Punishment)
question
A breakdown in learning ability caused by repeated exposure to uncontrollable aversive event. The tendency to fail to try or act in a situation because of a history of repeated failures in the past. Happens when the learner has no control over when punishment is given.
answer
Learned Helplessness
question
Continuous vs. partial Is the availability of reinforcement predictable? Fixed vs. Variable Is the availability of reinforcement related to the number of responses or the passage of time? Ratio vs. Interval
answer
Schedules of Reinforcement
question
Number of responses required for reinforcement is always the same (Airlines)
answer
Fixed Ratio
question
Interval of time that must pass before reinforcement becomes possible is always the same (pay day, baking)
answer
Fixed Interval
question
Schedule of reinforcement in which the number of responses required for reinforcement is different for each trial or event (Google)
answer
Variable Ratio
question
The interval of time that must pass before reinforcement becomes possible is different for each trial or event (Email)
answer
Variable Interval
question
Using operant conditioning to shape complex behavior. The reinforcement of simple steps in behavior through successive approximations that lead to a desired, more complex behavior (dancing dog)
answer
Shaping
question
Positively reinforcing numerous small steps of a more complex behavior in sequence in order to teach said complex behavior.
answer
Successive Approximation
question
The application of operant conditioning (and sometimes classical conditioning) techniques to bring about desired changes in behavior. Token economy- desired behavior rewarded with tokens that can be exchanged for something you want.
answer
Behavior Modification
question
Modern term for a form of behavior modification that uses shaping techniques to mold a desired behavior or response
answer
Applied Behavior Analysis (ABA)
question
In the early days of learning, researchers' focus was on behavior. In the 1950s- and more intensely in the 1960s- many psychologists were becoming aware that cognition, the mental events that take place inside a person's mind while behaving, could no longer be ignored.
answer

question
whether the subject is responding to a UCS or a CS.
answer
In classical conditioning, the actual response involved in a CR and a UCR are the same. (For example, it might be salivation in both cases.) However, what makes that response (salivation) considered conditioned or unconditioned depends on:

question
Lan is being positively reinforced for playing with the noisemaker. Kino is being negatively reinforced for giving Lan a lollipop.
answer
Kino's parents gave her four-year-old son, Lan, a noisemaker to celebrate his birthday. Since receiving the gift, Lan has played with his noisemaker everyday. Desperate for some peace and quiet, Kino gives Lan a lollipop, which takes Lan's attention away from the toy and gives Kino some peace and quiet. However, once the lollipop is gone, Lan returns to his noisemaker. Kino gives Lan another lollipop. In this example, what kind of reinforcement process is taking place?
