Learning
Term | Definition |
---|---|
Ivan Pavlov | known for his discovery of classical conditioning through his experiments with dogs |
John B. Watson | founded behaviorism and researched conditioning and found stimulus generalization |
B.F. Skinner | inventor of the Skinner Box, he discovered the power of positive reinforcement in learning through operant conditioning |
John Garcia | known for discovering exceptions to the process of learning by classical conditioning |
Edward Thorndike | his work on learning theory that lead to the development of operant conditioning within behaviorism |
Edward Tolman | best-known for cognitive behaviorism, his research on cognitive maps, the theory of latent learning |
Albert Bandura | they suggest that observation and modeling play a primary role in how and why people learn |
Unconditioned Stimulus (UCS) | a stimulus that automatically triggers a response EX: Food |
Unconditioned Response (UR) | the naturally occurring response to the UCS EX: Salivation |
Neural Stimulus (NS) | the CS before conditioning EX: Bell with no effect |
Conditioned Stimulus (CS) | a stimulus that has come to elicit a conditioned response EX: Bell with effect |
Conditioned Response (CR) | learned response to the previously neural stimuli EX: Dog salivates to bell |
Acquisition Learning Curve | involves pairing of the conditioned stimulus and the UCS, the greater # of pairing = stronger response |
Stimulus Generalization | occurs when a CR results from stimuli that are similar but unrelated |
Stimulus Discrimination | an organisms lack of response to a stimulus similar to the original stimulus |
Taste Aversion | when someone has a bad experience with a food and associates that bad experience with the food in the future |
Primary Reinforcer | stimuli that are biologically relevant to organisms and increase an organism's behavior towards it |
Secondary Reinforcer | a stimuli that has taken on the reinforcing properties of the primary reinforcer associated with it |
Fixed Ratio | a set # of responses before reinforcement is given |
Variable Ratio | the # of responses required vary around some average |
Fixed Interval | a set interval of time is needed for reinforcement to be given |
Variable Interval | reinforces a response at unpredictable rates |
Classical Conditioning | learning that takes place when a NS come to produce a CR because of its association with the UCS |
Operant Conditioning | method of learning that employs rewards and punishments for behavior |
Observational Learning | learning that takes place by watching others model a task |
Latent Learning | learning in the absence of apparent reinforcement |
Positive Reinforcement | occurs when a behavior is followed by a desired stimulus |
Negative Reinforcement | occurs when a behavior prevents or removes an aversive stimulus |
Shaping | technique whereby successive approximations of a behavior are reinforced |
Chaining | organisms are required to perform several different behaviors in sequence before receiving the reineforcement |
Extinction | when a behavior results in a reinforcer no longer results in the reinforcer |
Spontaneous Recovery | occurs when a previously extinguished CR suddenly randomly reappears |
Internal Locus of Control | believe that the outcomes of their actions are results of their own abilities |
External Locus of Control | attributes academic success or failure to luck or chance, a higher power or the influence of another person |
