Term
Adjunctive Behavior
Definition
behavior that occurs as a collateral effect of a schedule of periodic reinforcement for other behavior(time-filling or interim activities)
Term
Concurrent Schedule (conc)
Definition
2+ contingencies of reinforcement operate independently and simultaneously for 2+ behaviors
Term
Continuous Reinforcement (CRF)
Definition
each occurrence of the target behavior is reinforced
Term
Differential Reinforcement for Diminished Rates (DRD)
Definition
reinforcement is provided at the end of a predetermined interval contingent on the number of responses emitted during the interval being fewer than a gradually decreasing criterion based on the individual's performance in previous intervals. Can be decreased amount of events during the interval or increased time span with the same amount of events allowed.
Term
Differential Reinforcement for High Rates (DRH)
Definition
Reinforcement is provided at the end of a predetermined interval contingent on the number of responses emitted during the interval being greater than a gradually increasing criterion based on the individual's performance in previous intervals. Produces a higher rate of responding.
Term
Differential Reinforcement for Low Rates (DRL)
Definition
reinforcement (a) follows each occurrence of the target behavior that is separated from the previous response by a minimum IRT or (b) in contingent on the number of responses within a period of time not exceeding a predetermined criterion, not meant to eliminate the behavior. Produces a lower rate of behavior.
Term
Fixed Interval (FI)
Definition
reinforcement is delivered for the first response emitted following the passage of a fixed duration of time since the last response was reinforced
Term
intermittent schedule of reinforcement (INT)
Definition
A contingency of rein-forcement in which some, but not all, occurrences of the behavior produce reinforcemen
Term
Limited Hold (LH)
Definition
reinforcement is available ONLY during a finite time following the elapse of an FI or VI interval, reinforcement is withheld until the next interval.
Term
Matching Law
Definition
the allocation of responses to choices available on concurrent schedules of reinforcement; rates of responding across choices are distributed in proportions that match the rates of reinforcement received from each choice alternative
Term
Multiple Schedule (Mult)
Definition
consisting of 2+ basic schedules of reinforcement that occur in an alternating, usually random, sequence; a Sd is correlated with the presence or absence of each element of the schedule and reinforcement is delivered for meeting the response requirements of the element in effect at any time. Occur successively and independently.
Term
Post-reinforcement Pause
Definition
the absence of responding for a period of time following reinforcement; common during FI and FR
Term
ratio strain
Definition
A behavioral effect associated with abrupt increases in ratio requirements when moving from denser to thinner reinforcement schedules; common effects include avoidance, aggression, and unpredictable pauses or cessation in responding. When reinforcement cannot maintain the response level. When the response requirement exceeds the participants physiological capabilities.
Term
schedule of reinforcement
Definition
A rule specifying the environmental arrangements and response requirements for reinforcement; a description of a contingency of reinforcement.
Term
schedule thinning
Definition
Changing a contingency of reinforcement by gradually increasing the response ratio or the extent of the time interval; it results in a lower rate of reinforcement per responses, time, or both.
Term
variable interval (VI)
Definition
A schedule of reinforcement that provides reinforcement for the first correct response following the elapse of variable durations of time occurring in a random or unpredictable order. Produces a constant, stable rate of response
Term
variable ratio (VR
Definition
A schedule of reinforcement requiring a varying number of responses for reinforcement. Produce consistent, steady rates of response.
Term
Fixed ratio
Definition
reinforcement is delivered for the first response emitted following the passage of a fixed number of responses. Produce consistent, steady, rates of response.
Term
response unit
Definition
each ratio requirement. The responses required to produce reinforcement. Such as in a fixed ration schedule of reinforcement.
Term
Fixed interval scallop
Definition
A term to describe the way the rate of responding to fixed interval schedules looks on a graph. Represents a post-reinforcement pause, then a slow initial rate of response gradually accelerating toward the end of the interval and the contact with reinforcement.
Term
spaced responding DRL or DRH
Definition
reinforcement is available only for responses that are separated by a given duration of time.
Term
Full-session DRH or DRL
Definition
Provides reinforcement if the total number of responses during the session is (DRL) lower than, or (DRH) higher than the criterion limit.
Term
Interval DRL or DRH
Definition
reinforcement is available only for responses that occur at a better (higher or lower depending on DRL or DRH) rate of response over short durations of equal intervals of time within the session.
Term
lag schedule
Definition
Method used to increase response variability. Like Karen Prior with reinforcing only behavior they have never seen before. Reinforcement is contingent on a response differing in some predetermined way (topography, sequence) from one or more responses that preceded it. Each number after the ___ stands for the number of previous responses that the current response must be different from in order to contact reinforcement. ___infinity schedule means a response must be different from all prior responses.
Term
response variability
Definition
Diverse and novel forms of behavior.
Term
progressive schedule of reinforcement
Definition
systematically thins each successive reinforcement opportunity within the session independent of the participants behavior.
Term
Progressive -ration (PR) schedule of reinforcement
Definition
Within a session, a pattern of increasing ratio requirements, increased by adding a constant number or a constant proportion to the response requirements, until the end of the session. Comparing data using different reinforcers offers an assessment for the potency of a reinforcer.
Term
Delay to reinforcement schedules
Definition
After the criteria is met, a delay that is gradually increased is placed before the reinforcement contact. Also called delay fading. Learning to wait.
Term
behavioral contrast
Definition
changing schedule requirements in one component may affect responding in the unaltered components of a multiple schedule of reinforcement.
Term
Mixed schedule of reinforcement (MIX)
Definition
A nondiscriminated schedule of reinforcement. The same as multiple schedule of reinforcement, except no Sd signals the presence of the independent component schedules.
Term
Tandem schedule of reinforcement (TAND)
Definition
like chained schedule of reinforcement, but with no Sd for change in schedule
Term
Alternative Schedules of reinforcement
Definition
opportunity for reinforcement on two or more simultaneously available basic schedules of reinforcement. The first completed provides reinforcement, and then all schedule requirements start over following reinforcement.
Term
Conjunctive schedule of reinforcement (CONJ)
Definition
reinforcement follows completion of response requirements for two or more schedules of reinforcement.
Term
Chained (CHAIN) schedule of reinforcement
Definition
Two or more schedules, each with an Sd, operating in a specified sequence.
