Chapter 11 and 12 Flashcards
ABC model
Antecedents (Anything that prompts people to act), Behavior (Actions), Consequences (Effects of Behavior).
Positive reinforcement
three term contingency
S^d —>Response—–>S^r+
Discriminative Stimulus
A stimulus in the presence of which a particular response will be reinforced. S^D
Caveats to reinforcement
- Reinforcement does not increase behavior under all conditions.
Antecedent Stimuli - Reinforcement depends on motivation, SD will only signal the response if the individual is motivated to engage in the response.
Four term Contingency
The consideration of MOs are important in relation to the three term contingency.
EO—SD—-response—SR+
Reinforcer
Stimulus or consequence
ex. Attention, money, praise, food.
Reinforcement
Procedure or process
ex. Letting a child play outside as a consequence for cleaning up their room.
Immediacy of reinforcement
It is critical that the consequence is delivered immediately following the target response.
Automatic reinforcement
Reinforcement that occurs independent of another person delivering it. The response, itself, produces the reinforcement.
ex. Wiggling your leg during a boring lecture to stimulate yourself and stay awake.
Unconditioned reinforcers
Function as reinforcers due to heredity/evolution
◦ Do not require any learning history to become reinforcers
◦ Examples: Food, water, oxygen, warmth, sexual
stimulation, human touch
Conditioned Reinforcers
Neutral stimuli that begin to function as reinforcers as a result of being paired with other reinforcers (either conditioned or unconditioned)
◦ Can also condition reinforcers through verbal analog conditioning
◦ Examples: Yellow paper, stickers, tokens
Generalized Conditioned Reinforcers
A type of conditioned reinforcer that has been
paired with many conditioned and unconditioned
reinforcers
Formal properties of reinforcers
Edible reinforcers (food)
Sensory reinforcers (massage, tickles)
Tangible reinforcers (trinkets, toys)
Activity reinforcers (playing a game, recess)
Social reinforcers (physical proximity, social
interaction
Stimulus preference Assessments.
Reinforcer assessments
Negative reinforcement
Stimulus removed (terminated, reduced, or
postponed), Contingent on a response, Which results in an increase in the future probability of that response
Escape negative reinforcement
Presented with stimulus, Behavior terminates the stimulus
Avoidance negative reinforcement
Prevent onset of stimulus
Escape contingency
(EO) Rain fallingon your head as you walk down sidewalk—>
(SD) Friend says “Do you
have an umbrella —>(Response) Put up
umbrella
(SR) Escape rain falling on
your head
Putting up umbrella more likely in the future when it’s raining and friend asks
for umbrella
Avoidance contingency
EO—>SD—–REsponse—>SR
putting up umbrella before going outside.
Characteristics of negative Reinforcement
Any response (socially appropriate or
inappropriate) can be strengthened by negative
reinforcement
◦ All are adaptive because they allow the individual to
interact effectively with the environment
A variety of stimuli can serve as negative
reinforcers
◦ Unconditioned
◦ Conditioned
Automatic Reinforcement
Reinforcement that occurs independent of the social mediation of others (i.e. scratching an insect bite relieves the itch).
Conditioned Reinforcer
A stimulus change that functions as a reinforcer because of prior pairing with one or more other reinforcers.
