Learning
Question | Answer |
---|---|
learning | the process by which experience or practice results in a relatively permanent change in behavior or potential behavior |
classical contitioning | the type of learning in which a response naturally elicited by one stimilis comes to be elicited by a different, formaly neutral, stimulus |
unconditioned stimulus | a stimulus that invariably causes an organism to respond in a specific way |
unconditioned response | a response that takes place in an organism whenever an unconditioned stimulus occurs |
conditioned stimulus | an originally neutral stimulus that is paired with an unconditioned stimulus and eventually produces the desired response in an organism when presented alone |
conditioned response | after conditioning, the response an organism produces when a condtitioned simulus is presented |
intermittent pairing | pairing the conditioned stimulus and the unconditioned stimulus on only a portion of the learing trials |
desensitization therapy | a conditioning technique designed to gradually reduce anxiety about a particular object |
preparedness | a biological readiness to learn certain associations because of their survival advantages |
conditioned taste aversion | conditioned avoidance of certain foods even if there is only one pairing of conditioned and unconditioned stimuli |
operant conditioning | the type of learning in which behaviors are emitted to earn rewards or avoid punishments |
operant behaviors | behaviors designed to operate on the environment in a way that will gain something desired or aviod something unpleasant |
reinforcers | a stimuli that follows a behavior and increases the likelihood that the behavior will be repeated |
punishers | stimuli that follows a behavior and decreases the likelihood that the behavior will be repeated |
law of effect (principle of reinforcement) | Thorndike's theory that behavior consistently rewarded will be "stamped in" as learned behavior, and behavior that brings about discomfort will be "stamped out" |
Skinner box | a box often used in operant conditioning of animals; it limits the available responses and thus increases the likelihood that the desired response will occur |
shaping | reinforcing successive approximations to a desired behavior |
positive reinforcers | events whose presence increases the likelihood that ongoing behavior will recur |
negative reinforcers | events whose reduction or temination increases the likelihood that ongoing behavior will recur |
punishment | any event whose presence decreases the likelihood that ongoing behavior will recur |
avoidance training | learning a desirable behavior to prevent the occurrence of something unpleasent, such as punishment |
learned helplessness | failure to take steps to aviod or escape from an unpleasant or aversive stimulus that occurs as a result of previous exposure to unavoidable painful stimuli |
biofeedback | a technique that ises monitoring devices to provide precise informatioin about internal physiological process, such as heart rate or blood pressure, to teach people to gain voluntary control over these functions |
neurofeedback | a biofeedback technique that monitors brain waves with the use of an EEG to teach people to gain voluntary control over their brain wave activity |
contingency | a reliable "if-than" relationship between two events, such as a CS and a US |
blocking | a process whereby prior conditioning prevents conditioning to a second stimulus even when the two stimuli are presented simultaneously |
