Reinforcement
- the relationship between behavior and its consequences
- a few seconds apart
Positive Reinforcement
- a response is followed immediately by a favorable stimulus change
- increases the future occurrence of similar responses
Premack Principle
- behaviors on their own can be reinforcers
- The frequency of the behavior was important to see how effective it was as a reinforcer
Automatic Reinforcement
- ) The “behavior-stimulus change relation” is independent of social mediation
- ) A behavior persists without a reinforcer
- “default” situations/automatic reinforcement = the controlling variable
Socially Mediated Reinforcement
- Ex: of social reinforcers → physical contact (hugs, cuddles, tickling); attention; proximity; praise
- Attention from an adult is one of the most powerful reinforcers for young children
- social attention = unconditioned reinforcements
Conditioned Reinforcement
- a neutral stimulus is able to function as a reinforcer
- stimulus-stimulus pairing
- one or more unconditioned reinforcers or conditioned reinforcers are present
Unconditioned Reinforcement
- stimulus change that is reinforcement
- the learner has had no learning history with it
- innate reinforcement
Negative Reinforcement
- a response that is followed by the termination, reduction or postponement or avoidance of a (favorable) stimulus
- this leads to an increase in future occurrences
Aversive Stimulus
- stimulus that increases the frequency of the performance when terminated
Avoidance Contingency
- a response prevents or postpones the presentation of a stimuli
- ex: turn off loud noises; shield eyes from the sun; run from an aggressor (natural examples of escape con.)
Escape Contingency
- a response that terminates/produces escape from an ongoing stimulus (unfavorable)
- The subject needs to perform the targeted behavior in order to escape a stimuli that is unpleasant (very unethical with humans)
Schedule of Reinforcement
- the environment structure that determines conditions that allow behaviors to produce reinforcement
Continuous Reinforcement (aka CRF)
- provides reinforcement for each occurrence of behavior
- Used to strengthen behavior
Extinction (EXT)
no occurrence of the behavior produces reinforcement
Intermittent Reinforcement (INT)
- selected occurrences of the behavior produce reinforcement
- an intermittent schedule of reinforcement
Fixed Ratio (FR)
- a schedule of reinforcement that needs the completion of a fixed number of responses to produce a reinforcer
- ex: for every 4th target response, a reinforcer is admitted (FR 4 schedule)
Variable Ratio (VR)
- a schedule of reinforcement that needs the completion of a variable number of response to produce a reinforcer
- ex: VR 10 schedule → every 10th correct response on the average produces a reinforcement
Fixed Interval (FI)
- a schedule of reinforcement that gives reinforcement for the first response following a fixed duration of time
- the reinforcer is available after a fixed time (ex: FI 3-min schedule) and remains available until the first response
PRP (post reinforcement pause)
- response to FR
- the participant does not respond for a period following reinforcement
Schedule Training
- ) Thin an existing schedule by gradually increasing the the duration of the time interval
- ) Use instruction to clearly communicate the schedule of reinforcement
- facilitates a smooth transition during the thinning process
Ratio Strain
- result from abrupt increases in ratio requirements when moving from denser to thinner reinforcement schedules
- small and gradual increases in ratio requirements help to avoid the development of ratio strains
