Reinforcement

1

Q

Conditioned Reinforcers

A

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

Q

Positive Reinforcement

A

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

Q

Response-deprivation hypothesis

A

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.

Q

Social vs automatic reinforcement

A

Automatic reinforcement-occurs without presentation of consequences from others
Social reinforcement-does

Q

Describe some common mistakes in talking or writing about reinforcement

A
  • 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!

Q

Negative Reinforcement

A

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

Q

Fixed Ratio

A
  • 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

Q

Variable Ratio

A
  • Produces consistent, steady rates of response
  • Does not produce postreinforcement pause
  • Tends to produce a quick rate of response

Fixed Ratio

A

  • Size of ratio can influence the rate of response on FR schedules
  • postreinforcement pause-participant does not respond for a time following SR
17
Q

Variable Ratio

A
  • Produces consistent, steady rates of response
  • Tends to produce a quick rate of response
  • Does not produce postreinforcement pause
18
Q

Fixed Interval

A
  • Slow to moderate rates of response

- Postreinforcement pause produces a scallop effect-no responses right after will matter, so why do it?

19
Q

Variable Interval

A
  • Consistency of response: Constant, stable rate of response
  • Rate of responding: Low to moderate rate
20
Q

Multiple schedule (Mult)

A

Two or more basic schedules of SR in an alternating, usually random sequence. SD IS correlated with the presence or absence of each element of the schedule, and SR is delivered for meeting the response requirements of he element in effect at any time

21
Q

Mixed Schedule (mix)

A

Two or more basic schedule of SR in an alternating, usually random sequence. However, the mixed schedule has no SD correlated with the independent schedules

22
Q

S preference assessments

A
-Asking
Pros: Easy
Cons: Low correspondence between what people say and what people do
-Free-operant
Pros: Produce accurate results
Cons: May take longer?
-Trial based
Pros: Easy for table top tasks?
Cons: May not be accurate
23
Q

Reinforcement Assessments

A

Variety of direct, data-based methods used to present one or more stimuli contingent on a target response and then measuring the future effects on the rate of responding.

Concurrent Schedules-two or more contingencies of SR operate independently and simultaneously for 2 or more R
Multiple schedule-two or more component schedules of SR for a single response with only one component schedule in effect at a given time
Progressive-Ratio Schedule- Increases responses per presentation of the preferred S until a breaking point is reached and the response rate declines

24
Q

2 term contingency
3 term contingency
4 term contingency

A

R–> SR+
SD–>R–>SR+
EO–>SD–>R–>SR+
