Q

Critical Attributes of Reinforcement

A
  1. Environmental change must occur after the response
  2. Change must occur immediately after the response
  3. Change must be contingent on the response
  4. Defined by its effects on the bx (increase or maintain)

Q

Premack Principle

A

If the opportunity to engage in a “preferred” or “high probability” bx is made contingent on engaging in a “less-preferred” behavior, the future duration or frequency of the bx will increase

Q

Reinforcer

Study These Flashcards
A

Stimulus that when presented following a response increases or maintains the future frequency of that response

22
Q

Variable Attributes of Reinforcement

Study These Flashcards
A

Unconditioned to Conditioned
Positive or negative
Automatic or socially mediated
There are a variety of schedules of reinforcement
Occurs in nature but may also be programmed

23
Q

Unconditioned Reinforcer

Study These Flashcards
A

Stimulus that is reinforcing without prior learning and is due to phylogenic provenance; AKA primary reinforcers

24
Q

Conditioned Reinforcer

Study These Flashcards
A

Stimulus that initially has no innate reinforcing properties but acquires reinforcing properties through pairing with unconditioned reinforcers or powerful conditioned reinforcers; ontogenic provenance

25
Generalized conditioned reinforcers
Conditioned reinforcer that has been paired with a variety of other reinforcers and which is effective for a wide range of behaviors; less susceptible to deprivation and satiation effects
26
Positive reinforcement
Environmental change in which a stimulus is added or magnified following a response that increases or maintains future frequency of that response
27
Negative reinforcement
Environmental change in which a stimulus is subtracted/ attenuated following a response, and which increases or maintains the future frequency of that behavior. NOTE: there must be an irritant or aversive antecedent condition whose removal would be reinforcing.
28
Escape Behavior
Bx that terminates an aversive stimulus; thus it is maintained by negative reinforcement
29
Avoidance
Response usually terminates a "warning" stimulus; a warning stimulus is a conditioned aversive stimulus whose presence is correlated with the upcoming onset of an unconditioned aversive stimulus
30
Unsignaled Avoidance
There is no clear warring stimulus, but a response can still delay or prevent the occurrence of the aversive event; the aversive stimulus often occurs at regular intervals
31
Automatic Reinforcement
The response itself directly produces the reinforcing consequences and is not mediated by another person
32
Socially Mediated Reinforcement
Consequence is mediated by another person; may occur inadvertently or may be planned
33
Schedule of Reinforcement
Specifies criteria for reinforcement in terms of number of responses required and/or when the response occurs
34
Planned/ Programmed Reinforcement
A person explicitly arranged the contingency
35
Unplanned Reinforcement
Contingency was not explicitly arranged
36
Variables Affecting Reinforcer Effectiveness
``` Deprivation and Satiation Species-specific biological preparedness Response effort (response energy) Competing reinforcers Environmental context ```
37
Response Effort
The amount of effort involved for each of two or more responses is often a determining factor regarding reinforcer effectiveness for each response
38
Competing Reinforcers
Different reinforcers that are available at the same time for the same bx and/or for competing bx
39
Operant Extinction
Process by which a previously reinforced bx is weakened by withholding reinforcement
40
Critical Attributes of Extinction
1. Bx have been previously reinforced 2. Reinforcement withheld each and every time the bx occurs 3. The bx has to be weakened
41
Variable Attributes of Extinction
1. Organism may exhibit extinction burst following extinction 2. Organism may exhibit variation in topography and emotional responses following extinction 3. Extinction may involve withholding a stimulus or not withdrawing the aversive stimulus
42
Extinction Burst
When a previously reinforced bx is no longer reinforced, there is immediate and temporary increase in frequency, duration, and intensity before it decreases
43
Operant Spontaneous Recovery
Sudden and temporary reappearance of bx following extinction; after an operant bx no longer occurs as a result of extinction, the bx may reoccur at a later time in the same circumstances in which it was previously reinforced
44
Resurgence AKA Regression
Reappearance of a previously extinguished bx during the extinction of a more recently reinforced bx
45
Punishment
Environmental change which follows a response and which decreases the future frequency of that bx; defined by its effect on the specific bx it follows
46
Unconditioned Punisher
Stimulus that is usually punishing without any prior learning; effect due to phylogenic provenance
47
Conditioned Punisher
Stimulus that has initially no innate punishing properties but acquires punishing properties through pairing with unconditioned punishers or powerful conditioned punishers; effect due to ontogenic provenance
48
Positive Punishment
Environmental change in which a stimulus is added or magnified following a response that decreases the future frequency of that response
49
Negative Punishment
Environmental change in which a stimulus is subtracted or attenuated following a response which decreases the future frequency of that bx
50
Time Out from Positive Reinforcement
Procedure based on the principle of negative punishment; a response starts a timer and while the time is running, the organism cannot access reinforcers
51
Recovery from Punishment
Process by which a previously punished bx is strengthened by withholding punishment and the frequency of the bx increases in the future, usually to rates similar to baseline level
