Q

What is a reinforcer?

A

Any event that follows a behavior and increases the rate of that behavior.
It can follow the end of a behavior or the start of a behavior and occur concurrently (at the same time)
A proven reward

Q

What is the best way to prove that an event is a reinforcer?

Q

What is differential reinforcement?

A

a procedure involving two or more physically different behaviors where one is reinforced and all others are extinguished (rather than one behavior in two locations)

21
Q

How can you tell if the behaviors are different or not?

A

If the person is moving the same muscles in the same way no matter the other circumstances then it’s the same behavior

22
Q

Examples of only one behavior

A
  • making and not making a response (behavior and absence of behavior)
  • the same muscles in two locations
  • the same muscles at different times
  • reading different materials
  • saying the same words to different people
23
Q

Examples of two different behaviors

A
  • Same muscles at different speeds
  • Same muscles at different strengths
  • Talking about different topics
  • Pronouncing a word correctly and incorrectly
24
Q

What does differential reinforcement teach?

A

It teaches a person what response to make not when to make a response

25
Q

What is shaping?

A

The differential reinforcement of a series of successive approximations to a target behavior.

26
Q

What is a target behavior?

A

The ultimate goal of shaping

27
Q

What is successive approximation?

A

Any behavior that is similar to a target behavior for a program of shaping.
It is NOT a procedure, it is only an element in the procedure of shaping.

28
Q

What are the steps of shaping?

A
  1. Pick a target behavior as specific as possible
  2. Select successive approximations to the target behavior
  3. Differentially reinforce those approximations
29
Q

Guidelines of shaping

A
  1. Select a target behavior that is as specific as possible
  2. Select a reinforcer that is readily available, can be consumed quickly and immediately after the behavior, and won’t get tired of quickly
  3. Select initial behavior that occurs at least once during observation period and is as close to target behavior as possible.
  4. Explain goals of shaping to the person and move to next approximation when it’s correct 6 out of 10 times
30
Q

What are the 4 factors that cause events to be more effective?

A
  1. Event is contingent on the behavior
  2. Deliver immediately after behavior has occurred
  3. Size of the event is worthwhile
  4. Ensure that the person is deprived of the event (hasn’t had too much of the reinforcer)
31
Q

What is the principle of contingency on reinforcer effectiveness

A

The more consistently the reinforcer is delivered only for the desired behavior, the more effective the reinforcer
“Was the event given ONLY for a desired behavior?”

32
Q

What is the principle of immediacy on reinforcer effectiveness

A

The more immediate the delivery of the reinforcer aster the behavior, the more effective
“Was the event delivered within a MINUTE of the behavior?”

33
Q

What is the principle of size on reinforcer effectiveness

A

The more worthwhile the AMOUNT of the reinforcer, the more effective the reinforcer.
“Was the amount of the event used WORTHWHILE?”

34
Q

What is the principle of deprivation in reinforcer effectiveness?

A

The more deprived a person is of a reinforcer, the more effective the reinforcer
“Has the reinforcer RARELY been delivered?”

35
Q

Define deprivation

A

The frequency with which the person has received a particular reinforcer in the recent past. They are more deprived the less often they have received the event.

36
Q

What is establishing operations?

A

To label a broad range of events that increase reinforcer effectiveness. Any operation that establishes or increases the effectiveness of an event as a reinforcer.

37
Q

What is a Continuous Schedule of Reinforcement?

A

The delivery of a reinforcer is scheduled for every occurrence of the behavior
(FR-1)

38
Q

What is Extinction Schedule

A

The delivery of a reinforcer is scheduled to be withheld after occurrences of the behavior

39
Q

What is an intermittent schedule of reinforcement

A

When the delivery of a reinforcer is scheduled to follow only some occurrences of the behavior

40
Q

What is a fixed ratio schedule?

A

Reinforcing the first response after a fixed number of responses (abbreviate FR-#of responses -2 or more)

  • rapid responding prior to reinforcement then people tend to pause
  • higher rate of responding than intermittent schedules
  • respond faster when you increase the ratio (until reach upper limit)
41
Q

What is a variable ratio schedule?

A

Reinforcing the first response after a variable number of responses.

  • highest response rate since there is no pausing
  • greater resistance to extinction
42
Q

What are the advantages of ratio schedules?

A
  1. Resistance to extinction - you’ll keep going longer if you think you may still get a reinforcer. Not if you are used to getting one after each response
  2. Decreased satiation - fewer reinforcers produce the same amount of behavior.
43
Q

What are the disadvantages of ratio schedules?

A
  1. Continuous schedule needed for shaping - you have to reinforce every approximation
  2. Ratio strain - requiring so many responses for a reinforcer that the behavior slows or stops
44
Q

What is a fixed-interval schedule?

A

reinforcing the first response after a fixed period of time since the prior reinforcement
-creates a scallop pattern of responding, lower than fixed-ratio

45
Q

What is a variable-interval schedule?

A

reinforcing the first response after a varying period of time from the prior reinforcement
-produces work at a uniform rate, lower than variable-ratio

46
Q

Advantages of Interval schedules

A
  1. Reduce the problem of satiation

2. Resistance to Extinction

47
Q

Disadvantages of Interval Schedules

A
  1. Cannot use to shape a new behavior

2. Ratio strain - may deliver too little reinforcement to maintain responding

48
Q

Laws of behavior

A

The patterns produced by ratio and interval schedules are basic laws of behavior

49
Q

Superstitious reinforcement

A

If a person is reinforced after a fixed period of time no matter what they are doing at the time, they make up behaviors and act as if their behavior caused the reinforcement

50
Q

What is behavioral momentum?

A

People generate a high rate of responding if they have recently been reinforced frequently.
