1

What reinforcer effectiveness refers to

1. Momentary capacity to support responses that produce it.
2. Utility in producing long-term behavior change.

2

Operations that alter the prolonged value of a stimulus

Repeated exposure
Value enhancing effects/ Value diminishing effects
Stimulus Pairings
Contingency

3

Determinants of Stimulus Value

Delay
Rate
Quality
Magnitude
Motivating Operations

4

Delay as a determinant of stimulus value

Delays to reinforcement can weaken effectiveness of behavioral arrangements and result in the decrease in the value of a reinforcer.

5

Rate as a determinant of stimulus value

Rate of reinforcement affect relative response allocation

6

Organisms will distribute behavior among concurrently available alternatives in same proportion that reinforcers distributed among those alternatives

Matching Law

7

Conceptualized in terms of level of preference

Quality

8

Can vary according to quantity, intensity, or duration

Magnitude

9

An environmental event, operation, or stimulus condition that serves 2 functions

Motivating Operation

10

Two functions of MO

Reinforcer-establishing function
Evocative function

11

Momentarily alters the reinforcing effectiveness of other events

Reinforcer-establishing function

12

Momentarily alters the frequency of occurrence of the type of behaviors that produces those other events as a consequence

Evocative function

13

Momentarily increases the reinforcing effectiveness of stimulus and momentarily increases the frequency of behavior that produce the stimulus as a consequence

Stimulus deprivation

14

Momentarily decreases the reinforcing effectiveness of stimulus and momentarily decreases the frequency of behavior that produce the stimulus as a consequence

Stimulus satiation

15

Refers to sensitivity to price, extent to which changes in unit price influence consumption of the commodity

Elasticity of demand

16

Changes in price produce less than proportional changes in consumption

Inelastic demand

17

Changes in price produce larger than proportional changes in consumption

Elastic demand

18

What influences Elasticity of Demand?

Constraints on income
Open versus closed economies
Nature of available alternatives

19

Consumption of reinforcer not dependent on responding within earning context; supplemental access to reinforcer provided outside of earning context

Open economies

20

Consumption of reinforcer entirely dependent on responding within earning context; no supplemental access

Closed economies

21

Demand is more elastic when

Substitutable reinforcers are concurrently available

22

Reinforcers that share important functional properties

Substitutable reinforcers

23

Determinants of Stimulus Value

Contingency
Accumulation and Continuity
Variation and Choice

24

The amount of work the person has to complete to earn reinforcer influence the subsequent effectiveness of that reinforcer

Contingency

25

Reinforcers need not be consumed following each completion of a schedule requirement but rather can be accumulated then collected and consumed later

Accumulation

26

Reasons for accumulating reinforcers

Does not interrupt ongoing behavior
Requires fewer teacher resources

27

Procedures that interrupt continuity might alter the quality of the reinforcer, thus discounting its effectiveness

Continuity

28

Delivery of a brief period of access each time a small response requirement is met

Distributed reinforcement

29

Delivery of all reinforcement at the same time following the completion of a larger response requirement

Accumulated reinforcement

30

Conclusion about accumulation

Accumulated access mediated through tokens support:
Faster work
Greater overall quantity of work
Preferred by learner
