Omnibus Terms
Used to categorize stimuli that have multiple functions; Cover various functions of stimuli
2 Omnibus terms commonly used by behavior analysts
Aversive stimulus Appetitive stimulus
Aversive Stimulus
Its presentation evokes behavior that terminates it.Its onset weakens behavior that precedes its onset.Its offset strengthens behavior that precedes its offset.It may elicit smooth muscle and gland responses.
Appetitive Stimulus
Its onset strengthens behavior that precedes its onset.Its offset weakens behavior that precedes its offset. It abates behavior that removes it.It may elicit smooth muscle and gland responses.
Behavior Chain
A sequence of responses in which each response produces a stimulus change that functions as conditioned reinforcement for that response and as a discriminative stimulus for the next response in the chain
Induction
The spread of the effects of reinforcement to responses outside the limits of an operant class
Shaping
Thedifferential reinforcement of successive approximations to a target behavior
Shaping Across Topographies
The terminal target response is a distinct topography –a different response –than the response that is currently occurring
Shaping Within Topographies
The terminal target response is similar in form to the initial response, but varies across some dimension, such as rate or duration
Parameters of Reinforcement
Magnitude
Quantity
Duration
Schedule of Reinforcement
The rule that describes or specifies which responses will be followed by reinforcement and which will not
Continuous Reinforcement
Reinforcement occurs each and every single time the behavior occurs; used to establish or strengthen behavior.
Intermittent reinforcement
Some responses are reinforced and some are not; used to maintain already established behavior
Ratio
Reinforcement is delivered after a certain number of responses
Interval
Reinforcementis delivered for the FIRST response after a certain amount of time since the previous reinforcement
Fixed
Thenumber of responses, or amount of time, remains the same
Variable
Thenumber of responses, or amount of time, is random, but centers around (i.e., averages out to) a particular value
Limited Hold
A restriction placed on an interval schedule requiring that the response occur within a specified time limit following the interval to be eligible for reinforcement
FR schedules
All or none schedules, as they produce a pause in responding immediately after reinforcement,which is followed by a burst of responding. Pauses tend to be longer the thinner the schedule
VR schedules
Produce steady and high rates of responding
Ratio Strain
A behavioral effectassociated with abrupt increases in ratio requirements when moving from denser to thinner reinforcement schedules
FI schedules
Scalloped; Produce a pause in responding immediately after reinforcement,which is followed by a gradual increase in the rate of responding, with the highest rates at the time closest to reinforcement.
VI schedules
Produce steady, low to moderate rates of responding
Time-based Schedules
Apreferred stimulus is delivered at a point in time without a response requirement
