Chapter 6 Learning
Term | Definition |
---|---|
Acquisition in classical conditioning | Initial stage when one links a neutral stimulus & an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. |
Acquisition in operant conditioning | the strengthening of a reinforced response. |
Associative learning | Learning that two events occur together. |
Associative learning in classical conditioning | Events may be two stimuli |
Associative learning in operant conditioning | Response & it's consequences |
Behaviorism | view that psychology should be an objective science that studies behavior without reference to mental processes. |
Today most research psychologists believe behaviorism is | an objective science |
Biofeedback | System for electronically recording, amplifying & feeding back information regarding a subtle physiological stage- such as blood pressure or muscle tension |
Classical Conditioning | a type of learning which one learns to link two or more stimuli & anticipate events |
Cognitive Map | mental representation of the layout of one's environment.- exemplified by after exploring a maze rat's act as if they have learned a cognitive map of it. |
Conditioned Reinforcer | a stimulus that gains its reinforcing power through its association with a primary reinforcer |
Conditioned reinforcer also known as | secondary reinforcer |
Conditioned Response | (Classical Conditioning) the learned response to a previously neutral (but now conditioned) stimulus. |
Conditioned Stimulus | (Classical Conditioning) an originally irrelevant stimulus that after association with an unconditioned stimulus, comes to trigger a conditioned response |
Continuous Reinforcement | reinforcing the desired response every time it occurs |
Discrimination in classical conditioning | the learned ability to distinguish between a conditioned stimulus & stimuli that do not signal an unconditioned stimulus |
Discriminative Stimuluus | (Operant conditioning) a stimulus that elicits a response after association with reinforcement. |
Extinction- classical conditioning | the diminishing of a conditioned response- when an uncpnditioned stimulus does not follow a conditioned stumulus |
Extinction-operant conditioning | the diminishing of a conditioned response- when a response is no longer reinforced. |
Extrinsic Motivation | a desire to perform behavior to receive promised rewards or avoid threatened punishments. |
Intrinsic Motivation | a desire to perform behavior effectively for its own sake. |
Fixed-Interval Schedule | (operant conditioning) reinforcement schedule that reinforces a response only after a specified time has elapsed. |
Fixed-Ratio Schedule | (operant conditioning) a reinforcement schedule that reinforces a response only after a specified number of responses |
Generalization | tendency once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses. |
Habituation | decreasing responsiveness with repeated stimulation.- Infants gain familiarity with repeated exposure to visual stimuli their interest wanes. |
Higher-order conditioning | conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus. |
Insight | a sudden & often novel realization if the solution to a problem; it contrasts with strategy-based solutions. |
Latent Learning | learning that occurs but is not apparent until there is an incentive to demonstrate it |
Law of Effect | Thorndike's Principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely. |
Learned Helplessness | the hopelessness & passive resignation an animal or human learns when unable to avoid repeated aversive events |
Learning | a relatively permanent change in an organism's behavior due to experience |
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 & empathy. |
Modeling | the process of observing & imitating a specific behavior. |
Negative Reinforcement | increasing behaviors by stopping or reducing negative stimuli. A negative reinforcer is any stimulus that when removed after a response strengthens the response.- Negative reinforcer is not a punishment. |
Observational Learning | learning by observing others |
Observational learning is also called | social learning |
Operant Behavior | behavior that operates on the environment, producing consequences |
Operant chamber | also known as Skinner Box |
Operant Chamber | (Operant conditioning Research)- box containing a bar or key than an animal can manipulate to obtain food or water reinforcer; attached devices record the animal's rate of bar pressing or key pecking. |
Operant Conditioning | type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by punisher. |
Partial(intermittent) Reinforcement | reinforcing a response only part of the time |
Partial (intermittent) Reinforcement results in | slower acquisition & of a response but much greater resistance to extinction than does continuous reinforcement. |
Positive Reinforcement | Increasing behaviors by presenting positive stimuli. ex. food. |
A positive reinforcer is any stimulus that | when presented after a response, strengthens the response |
Primary Reinforcer | an innately reinforcing stimulus, such as one that satisfies a biological need. |
Prosocial behavior | positive, constructive,helpful behavior.- opposite of antisocial behavior |
Punishment | an event that decreases the behavior that it follows |
Reinforcer | (operant conditioning)- any event that strengthens the behavior it follows |
Respondent Behavior | behavior that occurs as an automatic response to some stimulus |
Shaping | operant conditioning procedure- which reinforcers guide behavior toward closer & closer approximation s of the desired behavior |
Spontaneous Recovery | the reappearance, after a pause, of an extinguished conditioned response |
Unconditioned Response | (Classical Conditioning)- the unlearned, naturally occurring response to the unconditioned stimulus. (ex. salivation when food is in mouth) |
Unconditioned Stimulus | (Classical conditioning)- a stimulus that unconditionally-naturally & automatically triggers a response. |
Variable-interval schedule | (operant conditioning)- a reinforcement schedule that reinforces a response at unpredictable time intervals. |
Variable-ratio schedule | (operant conditioning)- a reinforcement schedule that reinforces a response after an unpredictable number of responses |
