Psych Ch.8 Learning
Learning
| Question | Answer |
|---|---|
| learning | a relatively permanent change in an organism's behavior due to experience |
| associative learning | learning that certain events occur together. The events may bt two stimuli (classical conditioning) ot a response and its consequences (operant conditioning) |
| classical conditioning | a type of learning in which an organism comes to associate stimuli. A neutral stimulus that signals an unconditoned stimulus (UCS) begins to produce a response that anticipates and prepares fot the unconditioned stimulus |
| behaviorism | the view that psychology (1)should be an onjective science that (2)studies behavior without reference to mental processes. Most research psychologists today agree with (1)but not with (2) |
| unconditioned response (UCR) | in classical conditioning, the unlearned, naturally occuring response to the unconditioned stimulus (UCS), such as salivation when food is in the mouth |
| unconditioned stimulus (UCS) | in classical conditioning, a stimulus that unconditionally - naturally and automatically - triggers a response |
| conditioned response (CR) | in classical conditioning, the learned response to a previously neutral conditioned stimulus |
| conditioned stimulus (CS) | in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus (UCS), comes to trigger a conditioned response |
| acquisition | the intial stage in classical conditioning; the phase associating a neutral stimulus with an unconditioned stimulus so that the neutral stimulus comes to elicit a conditioned response. In operante conditioning, the strengthening of a reinforced response |
| extinction | the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (UCS) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced |
| spontaneous recovery | the reappearance, after rest period, of an extinguished conditioned response |
| generalization | the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses |
| discrimination | in classical conditioning, the learned ability to distinguish between a conditioned stimulus and other stimuli that do not signal an unconditioned stimulus |
| operant conditioning | a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher |
| respondent behavior | behavior that occurs as an automatic response to some stimulus; Skinner's term for behavior learned through classical conditioning |
| operant behavior | behavior that operates on the environment, producing consquences |
| law of effect | Thorndike's principle that behaviors followed by favorable consquences become more likely, and that behaviors followed by unfavorable consequences become less likely |
| operant chamber (Skinner box) | a chamber containing a bar or key that an animal can manipulate to obtain a food or water reinforcer, with attached devices to record the animal's rate of bar pressing or key pecking. Used in operant conditioning research |
| shaping | an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of a desired goal |
| reinforcer | in operant conditioning, any event that strengthens the behavior it follows |
| 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; aka secondary reinforcer |
| continuous reinforcement | reinforcing the desired response every time it occurs |
| partial (intermitten) reinforcement | reinforcing a response only part of the time; results in slower aquistion of a response but much greater resistance to extinction than does continuous reinforcement |
| fixed-ratio schedule | in operant conditioning, a schedule of reinforcement that reinforces a response only after a specified number of responses |
| variable-ratio schedule | in operant conditioning, a schedule of reinforcement that reinforces a response after an unpredicatable number of responses |
| fixed-interval schedule | in operant conditioning, a schedule of reinforcement that reinforces a response only after a specified time has elapsed |
| variable-interval schedule | in operant conditioning, a schedule of reinforcement that reinforces a response at unpredictable time intervals |
| punishment | an event that decreases the behavior that it follows |
| cognitive map | a mental representation of the layout of one's environment. For example, after exploring a maze, rats act as ig 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 |
| overjustification effect | the effect of promising a reward for doing what one already likes to do. The person may now see the reward, rather than the intrinsic intrest, as tha motivation for performing the task |
| intrinsic motivation | a desire to perform a behavior for its own sake and to be effective |
| extrinsic motivation | a desire to perform a behavior due to promised rewards or threats of punishment |
| observational learning | learning by observing others |
| modeling | the process of observing and imitating a specific behavior |
| mirror neurons | frontal lobe neurons that fire when performing certain actions or when observing another doing so. The brain's mirroring of another's action may enable imitation, language learning, and empathy |
| prosocial behavior | positive, constructive, helpful behavior. The opposite of antisocial behavior |
