Unit 5

Question 1

Antecedent

Answer 1

Stimulus that precedes or occurs before a response

Question 2

Variable Attributes of Antecedent

Answer 2

1. Environment is both outside and within the skin of an organism
2. Antecedents may be social or non-social

Question 3

Two Types of Antecedents

Answer 3

Discriminative Stimulus
Motivating Operations (MO)

Question 4

Effects of Antecedents on Bx

Answer 4

Evoke

Abate

Question 5

Evocative Effects of Antecedents

Answer 5

There is an increase in momentary frequency of the specific response class; effects are transitory and usually only last as long as the same conditions are present

Question 6

Abative Effects of Antecedents

Answer 6

There is a decrease in the momentary frequency of the specific response class; effects are transitory and usually only last long as the same conditions are present

Question 7

Two Operation in Differential Reinforcement

Answer 7

Reinforcement

Extinction

Question 8

Differentiation

R-S Contingency

Answer 8

If differential reinforcement consists of reinforcing some responses and not reinforcing other responses

Question 9

Discrimination

S-R-S Contingency

Answer 9

When differential reinforcement consists of reinforcing a response when certain stimuli are present and not reinforcing when those stimuli are not present

Question 10

Differential Reinforcement

Answer 10

Consists of reinforcement and extinction and leads to either differentiation or discrimination

Question 11

Differential reinforcement results in a stimuli which previously had no effect now being able to evoke or abate response

Answer 11

Function- altering effect

Question 12

Tendency of bx to occur more frequently in the presence of a particular stimulus because the bx has been reinforced only or mostly in the presence of that stimulus

Answer 12

Discriminative Control

Question 13

Antecedent stimulus evokes…

Answer 13

a response

Question 14

Discriminative stimulus (SD)

Answer 14

Antecedent stimulus which evokes or abates a specific bx due to past history of differential availability of reinforcement or punishment fro that bx, dependent on their presence or absence

Question 15

How SD is established

Answer 15

Through the process of differential reinforcement which leads to discrimination

Question 16

Discriminated Operant

Answer 16

Operant class that is established through the process of differential reinforcement with respect to the presence or absence of

Question 17

Types of SD

Answer 17

SD for SR (SD for reinforcement)
SDelta for SR
SD for Punishment
SDelta for Punishment

Question 18

SD for SR (SD for reinforcement)

Answer 18

Evokes bx because in the past that bx has been reinforced in its presence; correlated with greater availability of reinforcement; signals that reinforcement is available for a specific bx

Question 19

How likely is it that the reinforcer will follow a specific response now?

Answer 19

Availability

Question 20

8 Subtypes of SD

Answer 20

SD for SR+
SD for SR-
S^ for SR+
S^ for SR-
SD for P+
SD for P-
S^ for P-
S^ for P

Question 21

Conditional Discrimination

Answer 21

Discrimination in which reinforcing a response is contingent on another stimulus (4 term contingency)

Question 22

Tendency of a learned response to occur in the presence of stimuli which were not present during training but which either have some similar physical properties to the SD or have been associated with SD

Answer 22

Stimulus Generalization

Same response; different stimuli

Question 23

Stimulus generalization occurs when….

Answer 23

discriminative control is absent or incomplete
