CSU Skinner Terminology
Question | Answer |
---|---|
Continuous reinforcement | Every time a specific action is performed the subject instantly and always receives a reinforcement. This method is hard to carry out, and the reinforced behavior is prone to extinction. |
Fixed Interval reinforcement | Reinforcement is set for a certain time duration. Times between reinforcements are not set, and often differ. |
Fixed Ratio reinforcement | Deals with a set amount of work needed to be completed before there is reinforcement. |
Positive reinforcement | When a behavior is followed by a favorable stimulus that increases the frequency of that behavior. |
Negative reinforcement | When a behavior is followed by the removal of an aversive stimulus thereby increasing that behavior's frequency. |
Punishment | When a behavior is followed by an aversive stimulus, such as introducing a shock or loud noise, resulting in a decrease in that behavior. Skinner did NOT advocate using punishment. |
Extinction | The removal of a reinforcer (lack of any consequence following a behavior) causing a behavior to decrease in frequency. |
Intermittent Reinforcement | When we reinforce a behavior only sometimes instead of every time it happens. |
Fading | A gradual change of a stimulus while the response stays about the same. Starts with a strong stimulus which is faded.(e.g., Teaching "sit" to a dog; start with a loud command. Slowly fade out loud command to a whisper. |
Shaping | successive approximation. Involves reinforcing successive, increasingly accurate approximations of a response desired by a trainer. |
Chaining | Involves linking discrete behaviors together in a series, The number of steps completed by the client increases sequentially over time as each step is mastered. |
Time-Outs | A form of withdrawing positive reinforcement by removing the individual from the reinforcing situation (NOT to be used as punishment). |
