Flashcards in Stimulus Control and Generalization Deck (28):
1

Stimulus control occurs when...

the rate, latency, duration of response is altered in the presence of an antecedent stimulus.

2

Stimulus control is acquired when...

Responses are reinforced in the presence of a specific stimulus (Sd) and not in the presence of other stimuli (S^).

3

Sd -> response -> Sr+

phone rings -> pick up phone -> conversation

4

S^ -> response -> S

doorbell -> pick up phone -> no conversation

5

A class of behaviour created through differential reinforcement with respect to stimulus properties.

Discriminated operant

6

Events that precede operants and set the occasion for the behaviour to occur.

Discriminative stimuli

7

Discrimination training

Two antecedent stimuli (Sd and S^).
Responses that occur in presence of Sd are reinforced, and responses that occur in presence of S^ are not.

8

Stimuli that share similar physical characteristics with the controlling stimulus evokes the same behaviour as the controlling stimulus.

Stimulus generalization

9

The spread of effects of reinforcement during one stimulus to another stimulus differing from the original along one or more physical dimensions.

Generalization

10

Little discrimination =

more generalization

11

Greater discrimination =

less generalization

12

Successive procedure

Sd and S^ alternate usually randomly

13

Simultaneous procedure

Sd and S^ presented at the same time

14

Matching-to-sample

select from two or more comparison stimuli.

15

3 elements of simple discrimination

Discriminative stimulus, response, and consequence

16

4 elements of conditional discrimination

Conditional stimuli, antecedent stimuli, responses, and consequences.

17

Arbitrary

Researcher decides the links between the stimuli

18

Non-arbitrary

Physical similarity controls the response.

19

Error-less discrimination training

Start with the Sd and gradually introduce S^

20

Stimulus generalization within a class of stimuli and stimulus discrimination between classes of stimuli

Concept formation

21

Pigeons tested with novel pictures of people and trees. Showed concept-formation

Herrnstein et al (1976)

22

Chickens and grey coloured squares

Kohler (1939)

23

Feature stimulus class

Share common physical forms, relative relationship and developed through stimulus generalization.

24

Arbitrary stimulus class

No common features, developed using stimulus equivalence.

25

A prerequisite skill for stimulus control. May need to be taught before stimulus control procedures are implemented.

Pre-attending skills

26

Prominence of the stimulus in the environment. Increases rate of acquisition.

Stimulus salience

27

Mask a response due to your previous history with that stimulus

Masking

28

One stimulus is more prominent than others and so is responded to.
