Learning
Term | Definition |
---|---|
Learning | Lasting change in behavior or mental processes that result from experience |
Habituation | Learning not to respond to the repeated presentation of a stimulus |
Mere Exposure Effect | A learned preference for stimuli to which we have been previously exposed |
Behavioral Learning | Forms of learning, such as classical conditioning and operant conditioning, that can be described in terms of stimuli and responses |
Classical Conditioning | A form of behavioral learning in which a previous neutral stimulus acquires the power to elicit the same innate reflex produced by another stimulus |
Neutral Stimulus | Any stimulus that produces no conditioned response prior to learning |
Unconditioned Stimulus (UCS) | In classical conditioning, the stimulus that elicits an unconditioned response |
Unconditioned Response (UCR) | In classical conditioning, the response elicited by an unconditional stimulus without prior learning |
Acquisition | The initial learning stage in classical conditioning, during which the conditioned response comes to be elicited by the conditioned stimulus |
Conditioned Stimulus (CS) | In classical conditioning, a previously neutral stimulus that comes to elicit the conditioned response |
Conditioned Response (CR) | In classical conditioning, a response elicited by a previously neutral stimulus that has become associated with the unconditioned stimulus |
Extinction | The weakening of a conditioned response in the absene of an unconditioned stimulus |
Spontaneous Recovery | The reappearance of an extinguished conditioned response after a time delay |
Stimulus Generalization | The extension of a learned response to stimuli that are similar to the conditioned stimulus |
Stimulus Discrimination | A change in responses to one stimulus but not to stimuli that are similar |
Experimental Neurosis | a pattern of erratic behavior resulting from a demanding discrimination learning task, typically one that involves aversive stimuli |
Taste-Aversion Learning | A biological tendency in which an organism learns, after a single experience, to avid a food with a certain taste, if eating it is followed by illness |
Operant Conditioning | Form of behavioral learning in which the probability of a response is changed by its consequences--that is, by the stimuli that follow the response |
Law of Effect | The idea that responses that produced desirable results would be learned, or "stamped" into the organism |
Reinforcer | Condition that occurs after a response and strenghtens that response |
Positive Reinforcement | Stimulus presented after a response and increasing the probability of that response happening again |
Negative Reinforcement | Removal of an unpleasant or aversive stimulus, contingent on a particular behavior |
Reinforcement Contingencies | Relationships between a response and the changes in stimulation that follow the response |
Shaping | Operant learning technique in which a new behavior is produced by reinforcing responses that are similar to the desired response |
Intermittent Reinforcement | Type of reinforcement schedule by which some, but not all, correct responses are reinforced |
Extinction | A process by which a response that has been learned is weakened by the absence or removal of reinforcement |
Schedules of Reinforcement | Programs specifying the frequency and timing of reinforcements |
Ration Schedule | Program by which reinforcement depends on the number of correct responses |
Interval Schedule | Program by which reinforcement depends on the time interval elapsed since the last reinforcement |
Fixed Ratio (FR) Schedules | Programs by which reinforcement is contingent on a certain, unvarying number of responses |
Variable Ration (VR) Schedules | Programs by which the number of responses required for a reinforcement varies from trial to trial |
Fixed Interval (FI) Schedules | Programs by which reinforcement is contingent on certain, fixed time periods |
Variable Interval (VI) Schedules | Programs by which the time period between reinforcements varies from trial to trial |
Primary Reinforcers | Reinforcers, such as food and sex, that have an innate basis because of their biological value to an organism |
Secondary Reinforcers (Conditioned Reinforcers) | Stimuli, such as money or tokens, that acquire their reinforcing power by a learned association with primary reinforcers |
Token Economy | Therapeutic method, based on operant conditioning, by which individuals are rewarded with tokens, which act as secondary reinforcers. The tokens can be redeemed for a variety of rewards and privileges |
Premack Principle | Concept developed by David Premack, that a more-preferred activity can be used to reinforce a less-preferred activity |
Punishment | An aversive stimulus which, occurring after a response, diminishes the strength of that response |
Positive Punishment | Application of an aversive stimulus after a response |
Negative Punishment (Ommission Training) | Removal of an appetitive stimulus after a response, leading to a decrease in behavior |
Insight Learning | Form of cognitive learning, originally describe by the Gestalt psychologists, in which problem solving occurs by means of sudden reorganization of perceptions |
