Unit 3 Part 2 Flashcards
Extinction
In classical conditioning, the diminishing of a conditioned response when an unconditioned stimulus does not follow a conditioned stimulus. (In operant conditioning, when a response is no longer reinforced.)
Spontaneous Recovery
The reappearance, after a pause, of a weakened conditioned response
Generalization
(Also called stimulus generalization) in classical conditioning, the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses. (In operant conditioning, when responses learned in one situation occur in other, similar situations.)
Discrimination
In classical conditioning, the learned ability to distinguish between a conditioned stimulus and other stimuli that have not been associated with a conditioned stimulus. (In operant conditioning, the ability to distinguish responses that are reinforced from similar responses that are not reinforced.)
Preparedness
A biological predisposition to learn associations, such as between taste and nausea, that have survival value
John Garcia
Discovered the Garcia effect which shows that organisms will avoid certain foods that they have eaten near the time they experience nausea or vomiting
Operant conditioning
A type of learning in which a behavior becomes more likely to recur if followed by a reinforcer or less likely to recur if followed by a punisher
B.F. Skinner
“Father” of Behavior Analysis. Developed a theory of learning which says that a person is first exposed to a stimulus, which elicits a response, and the response is then reinforced (stimulus, response, reinforcement). Ultimately conditioning our behaviors
Developed the theory of operant conditioning, which posits that behavior is determined by its consequences, be they reinforcements or punishments
Edward L. Thorndike
Proposed the law of effect, stating that behaviors followed by satisfying consequences become more likely to occur in the future, and those followed by unsatisfying consequences become less likely
Law of effect
Thorndike’s principle that behaviors followed by favorable (or reinforcing) consequences become more likely, and that behaviors followed by unfavorable (or punishing) consequences become less likely
Operant chamber
In operant conditioning research, a chamber (also known as a Skinner box) containing a bar or key that an animal can manipulate to obtain a food or water reinforcer; attached devices record the animal’s rate of bar pressing or key pecking
Reinforcement
In operant conditioning, any event that strengthens the behavior it follows
Shaping
An operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior
Cognitive map
A mental representation of the layout of one’s environment. For example, after exploring a maze, rats act as if they have learned a cognitive map of it
Latent learning
Learning that occurs but is not apparent until there is an incentive to demonstrate it
Insight learning
Solving problems through sudden insight; contrasts with strategy-based solutions
Observational learning
Learning by observing others. (Also called social learning.)
Modeling
The process of observing and imitating a specific behavior
Albert Bandura
Developed his “Social Learning Theory” and the famous “Bobo Doll Experiment,” which demonstrated how children can learn aggressive behaviors by observing others acting aggressively
Prosocial behavior
Positive, constructive, helpful behavior. The opposite of antisocial behavior.
Mirror neurons
Neurons that some scientists believe fire when we perform certain actions or observe another doing so. The brain’s mirroring of another’s action may enable imitation and empathy
Antisocial behavior
Negative, destructive, harmful behavior. The opposite of prosocial behavior
Punishment
An event that tends to decrease the behavior that it follows
Variable interval schedule
In operant conditioning, a reinforcement schedule that reinforces a response at unpredictable time intervals
Fixed interval schedule
In operant conditioning, a reinforcement schedule that reinforces a response only after a specified time has elapsed
Discriminative stimulus
In operant conditioning, a stimulus that elicits a response after association with reinforcement (in contrast to related stimuli not associated with reinforcement)
Positive reinforcement
Increasing behaviors by presenting a pleasurable stimulus. A positive reinforcer is any stimulus that, when presented after a response, strengthens the response
Negative reinforcement
Increasing behaviors by stopping or reducing an aversive stimulus. A negative reinforcer is any stimulus that, when removed after a response, strengthens the response. (Note: Negative reinforcement is not punishment.)
Primary reinforcer
An innately reinforcing stimulus, such as one that satisfies a biological need
Conditioned reinforcer
A stimulus that gains its reinforcing power through its association with a primary reinforcer; also known as a secondary reinforcer
Reinforcement schedule
A pattern that defines how often a desired response will be reinforced
Continuous reinforcement schedule
Reinforcing the desired response every time it occurs
Partial (Intermittent) reinforcement schedule
Reinforcing a response only part of the time; results in slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement
Fixed-ratio schedule
In operant conditioning, a reinforcement schedule that reinforces a response only after a specified number of responses
Variable-ratio schedule
In operant conditioning, a reinforcement schedule that reinforces a response after an unpredictable number of responses
