Lecture 4 F

Question 1

What is stimulus control?

Answer 1

The likelihood of a response varies according to the stimuli present at the times

Question 2

What does stimulus control of our?

Answer 2

Stimulus control of a behaviour occurs when the performance of a particular behaviour is controlled by the presence or absence of a discriminative stimulus

Question 3

What is a discriminative stimulus?

Answer 3

A stimulus in the present of which responses of some type have been reinforced and in the absence of which the same response have not been reinforced

Question 4

How does discriminative stimuli work?

Answer 4

By telling us what behaviours will get reinforced or punished

When we reliably and predictably change our behaviour in the presence of discriminative stimulus we are said to be under stimulus control

Question 5

What factors are important in stimulus control?

Answer 5

Generalisation

Discrimination

-the nature of the cue

Question 6

What is generalisation?

Answer 6

The likelihood that an animal will respond similarly to different stimuli if they have comparable properties

The transfer of a learner response to a different but similar stimuli

Question 7

Give an example of generalisation

Answer 7

CS: Large black dog
CR: Fear

Stimulus generalisation: fear of large dogs or fear of smaller sized black dogs

Question 8

What is discrimination?

Answer 8

The learned ability to distinguish between two stimuli that are similar
- behaving differently in different situation

Question 9

What is a generalisation gradient?

Answer 9

Measure of generalisation/ discrimination

Train for one stimulus and test on others

Question 10

What is errorless learning?

Answer 10

Allows discrimination to occur with a few (or even no) responses to the negative stimuli

(25 responses to stimulus vs 3000 responses)

Question 11

How would you train a task unsung errorless learning?

Answer 11

Train a behaviour

• salient stimulus clear, others peripheral
• gradually increase salience of “distractors”
• learning without error- emotional benefits?

Question 12

What are the components of stimulus control?

Answer 12

Perform on a cue
Always
- no matter where or when or by whom
Immediately 
Not perform behaviour if no cue

Question 13

How to train with discrimination

Answer 13

• Pair cue with behaviour
• Only reinforce behaviour presented on cue
• Reinforce absence of behaviour in absence of cue

Question 14

How would you increase generalisation in training?

Answer 14

By training in a variety of settings

Practice in numerous situations

Numerous people giving cue
