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

Q

4 types of antecedent

A
  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

Q

stimulus control

A

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

Q

holland and skinner experiment with pigeons

A

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).

Q

three term contingency notation

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

Q

stimulus equivalence

A

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

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