Lecture 3

Question 1

A contingency in which a response terminates an ongoing stimulus.

Answer 1

Escape Contingency

Question 2

A contingency in which a response prevents or postpones the presentation of a stimulus.

Answer 2

Avoidance contingency

Question 3

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

Answer 3

Stimulus control

Question 4

Learned behaviour occurs in one situation but not in another situation.

Answer 4

Discriminative stimulus

Question 5

Non availabilty of reinforcement

Answer 5

Stimulus delta

Question 6

An operant that occurs more frequently under some antecedent conditions than others.

Answer 6

Discriminated operant

Question 7

When stimuli share similar physical charecteristics when the controlling stimulus evoke the same behaviour as the controlling stimulus.

Answer 7

Stimulus generalization

Question 8

A procedure for investigating conditonal relations and stimulus equivalence

Answer 8

Matching to sample

Question 9

Both Sd and S ^ are presented at the same time.

Answer 9

Simulataneous procedure

Question 10

Sd and S^ alternate usually randomly. When Sd appears responding is reinforced; when S^ appears responding is on extinction.

Answer 10

Successive procedure

Question 11

Involves 3 elements- discriminative stimulus, response and consequence.

Answer 11

Simple discrimination

Question 12

Established by reinforcing responses to particular antecedents if and only if they are preceded or accompanied by particular additional stimuli

Answer 12

Conditional discrimination

Question 13

A complex example of stimulus control that requires stimulus generalization within a class of stimuli and discrimination between classes of stimuli.

Answer 13

Concept formation

Question 14

Stimuli that share common physical forms or structures or common relative relationships.

Answer 14

Feature stimuli class

Question 15

Dont not share a common stimulus feature, devlop using stimulus equivelence.

Answer 15

Arbitrary stimulus class

Question 16

Prominence of the stimulus in the environment. Increase saliency facilitates efficiency of instruction.

Answer 16

Stimulus Salience

Question 17

Even though one stimulus has acquired stimulus control over behaviour, a competing stimulus can block the evocative function of that stimulus.

Answer 17

Masking

Question 18

The presence of one stimulus condition interferes with the acquistion of stimulus control by another stimulus.

Answer 18

Overshadowing
