Chapters 11-13 Flashcards
Reinforcement
Unconditioned Reinforcer
Stimulus change that functions as SR even though the learner has had no particular learning history with it
Examples of unconditioned reinforcers
Food, water, rest, shelter, sex, mental stimulation
Conditioned Reinforcers
Previously neutral stimulus change that has acquired the capability to function as a Sr through S-S pairing with one or more UCR or CR. Be able to name examples
Positive Reinforcement
Occurs when a response is followed immediately by the presentation of a S and, as a result, similar responses occur more frequently in the future
Response-deprivation hypothesis
Model for predicting whether access to one R (the contingent R) will function as SR for another R (the instrumental response) based on the relative baseline rates at which each R occurs and whether access to the contingent R represents a restriction compared to the baseline level of engagement.
Give example of Response-deprivation hypothesis
name an example where deprivation from one behavior will function as a reinforcer for another behavior
Social vs automatic reinforcement
Automatic reinforcement-occurs without presentation of consequences from others
Social reinforcement-does
Describe some common mistakes in talking or writing about reinforcement
- Reinforcing the person (Reinforcing the behavior)
- Practice as reinforcement for a skill (Not unless the practice makes the skill happen more often!)
- Artificial SR (contrived)
- SR and feedback as synonyms (feedback may or may not increase frequency of R)
- Remember, better to correctly use commonsense language than incorrectly use technical language!
Negative Reinforcement
Contingency in which the occurrence of a response produces the removal, termination, reduction, or postponement of a S, which leads to an increase in the future occurrence of that response. Give an example
Methods of identifying potential Srs (Diagram on page 275)
Stimulus Preference assessments and reinforcer assessments
Escape contingency
A response terminates an ongoing S
Avoidance Contingency
A response prevents or postpones the presentation of a S
Name the basic schedules of reinforcement
FR, VR, FI, VI
Fixed Ratio
- often produce high rates of response
- size of ratio can influence the rate of response on FR schedules
- postreinforcement pause-participant does not respond for a time following SR
Variable Ratio
- Produces consistent, steady rates of response
- Does not produce postreinforcement pause
- Tends to produce a quick rate of response
