Module 4 Flashcards
reinforcement
behavior is followed closely in time by a stimulus event and as a result the future frequency of that type of behavior
reinforcer
a stimulus
reinforcing
property of a stimulus
reinforcement
operation: delivery of consequences when a response occurs
and a process: the increase of responding that results from reinforcement
reinforce
operation and process
positive reinforcement
when response is followed by a stimulus and as a result similar responses occur more frequently in the future
positive reinforcer
the stimulus presented as a consequence and responsible for the subsequent increase in responding
negative reinforcement
occurence of removal, termination, reduction or postponement of a stimulus which leads to an increase in the future occurence or response
negative reinforcer
stimuli whose removal strengthens behavior
unconditioned reinforcers
a stimulus that can increase the future frequency of behavior without prior pairing with any other form of reinforcement
referred to as primary
conditioned reinforcers
a perviously neutral stimulus that has acquired function of reinforcer through stimulus-stimulus pairing
secondary
generalized conditioned reinforcers
having been paired with many unconditioned and conditioned reinforcers does not depend on a current EO for any particular form of reinforcement for its effectiveness
differential reinforcement
DRA: alternative behavior DRO: other behavior DRL: low rates DRI: incompatible DRH: high rates DRD: diminishing rates
automatice reinforcement
some behaviors produce their own reinforcement independent of the mediation of others
premark principle
making the opportunity to engage in a behavior that occurs at a relatively high free operant (or baseline) rate contingent on the occurence of low-frequency behavior will function as reinforcement for the low-frequency behavior
variables affecting reinforcement
motivation
- satiation, deprivation
motivating operations
- establishing, abolishing
immediacy
- reinforcer must immediately follow response
- fade over time
set an easily achievable initial criterion for reinforcement
use high quality reinforcers
use varied reinforcers
use direct reinforcers
combine response prompts with reinforcement
reinforce each occurence initially
use contingent attention and descriptive praise
gradually increase response- to reinforcement delay
gradually shift from contrived to naturally occurring reinforcers
some useful domains
edible-can lead to satiation sensory tangible activity social
4 schedules of reinforcement
fixed-interval
variable-interval
fixed-ratio
variable-ratio
schedule of reinforcement
continuous: reinforcer after every occurence
intermittent: reinforcing target response occasionally
fixed-interval
time based: reinforcement delivered after a specific amount of time
time period is fixed
reinforcer delivered contingent upon the first behavior following the time period
results in a scallop pattern of responding
- more responses as the time period elapses
variable-interval
time baed
time period is variable
reinforcer delivered contingent upon first behavior following the time period
results in a consistent rate of responding
fixed ratio schedule
response based
requires completion of a specified number of responses to produce a reinforcer
results in rapid rates of responding
variable-ratio
response based
requires a completion of a variable number of responses
results in rapid rates of responding
Complex schedules
progressive concurrent multiple mixed tandem
