Stimulus control

Question 1

what is the three term contingency

Answer 1

• quickly summarizes operant conditioning
• also known as the ABCs behaviour
• antecedent signal results in behaviour which result in consequences

Question 2

what are antecedents

Answer 2

a stimuli, event, or situation that precedes behaviour. provides contexts that consequences occurs in. all antecedent are stimuli

Question 3

4 types of antecedent

Answer 3

1. overt antecedent = stimuli directly observable with your senses.
2. covert antecedent = stimuli that is not directly observable by other people. internal experiences
3. immediate antecedent = occurs right before or overlaps with behaviour. e.g. fire alarm
4. distant antecedent = stimuli (often covert) that preceded behaviour a long time ago. can influence behaviour for a long time.
   -medication effect, health status, history of abuse
   every antecedent is overt or covert, and immediate or distant

Question 4

stimulus control

Answer 4

extent to which antecedent stimuli can influence performance of particular behaviour
->when stimulus exercises high level of stimulus control, behaviour is highly likely to occur in presence of stimuli

Question 5

stimulus discrimination training

Answer 5

administering a specific consequence for a behaviour when a stimulus is present, but not when another stimulus is present

Question 6

discriminative stimulus (Sd)

Answer 6

behaviour is promised to be reinforced

Question 7

antecedent stimulus (Sdelta)

Answer 7

behaviour is not reinforced

Question 8

holland and skinner experiment with pigeons

Answer 8

pigeon was placed in operant conditioning chamber. when disk was illuminated with red light and pigeon pecked it, gave food (discriminative stimulus). when illuminated with green light and pigeon pecked it, no food (antecedent stimuli).

Question 9

real life situations using stimulus discrimination training typically involve ____

Answer 9

multiple antecedent

e.g. passing a car

Question 10

three term contingency notation

Answer 10

Sr (reinforcement)
e.g.
Sd -> R -> Sr
Sdelta -> R -> nothing
*if minus sign behind the r, negative reinforcement. if plus sign, positive reinforcement

Question 11

stimulus generalization

Answer 11

occurs when a stimulus similar to Sd (discriminative stimulus) also produces a behaviour

Question 12

generalization gradient

Answer 12

stimuli most similar to Sd produces the strongest response

Question 13

stimulus equivalence

Answer 13

two or more stimuli can be used for the same purpose.

e.g. number 4 can be written as 4, IV, four, etc.
