An antecedent stimulus that is present when a behavior is reinforced is called

discriminative stimulus

An antecedent stimulus that is present when a behavior is not reinforced is called a

stimulus delta

is when a behavior is more likely to occur in the presence of a specific antecedent stimulus

stimulus control

How do you develop stimulus control

through stimulus discrimination training

3 components of a 3-term contingency

SD (antecdent), response, S (consequence or reinforcer)

stimulus discrimination training

reinforce behavior when the SD is present and not when the S delta is present

as a result of D-training, what happens in the future when an SD is present

the behavior is more likely to occur

____ is developed through the process of discrimination training

stimulus control

___ takes place when a behavior occurs in the presence of stimuli that are similar to the SD


When a novel example of SD occurs, this is called...


example of stimulus control

any example where a behavior is more likely to happen in the presence of a specific stimulus

shaping involves differential reinforcement of ______ of a target behavior

successive approximations

In shaping, the first behavior chosen for reinforcement is called the

starting behavior

2 behavioral principles involved in differential reinforcement

reinforcement, extinction

it is important to use a _______ reinforcer in order to be able to deliver the reinforcer immediately after the desired effect during shaping.


shaping is used for 3 reasons....

novel or new topogrpahy, to reinstate a previously exhibited behavior, to change some dimension of an existing behavior

you would not use shaping when _____ could be used to get the person to engage in the target behavior

modeling, instructions, or other prompts

if the behavior already occurs occasionally, you _____ use shaping.

do not , because you can use reinforcement instead

Shaping involves _____ of successive approximations of a target behavior

differential reinforcement

the steps in a shaping procedure are called

succesive approximations

Three shaping steps that are reinforced when teaching a young child to talk

babbling, word sounds, words

In shaping, CR are important to use so that the reinforcer does not lose its effectiveness through


if the target behavior is occurring at least occasionally, you would use _____ to make it occur more often

differential reinforcement

in shaping, each ____ is a behavior that is more and more like the target behavior

succesive approximation

if you were using shaping to get a rat to press a lever, pressing the lever would be called the ___

target behavior

you do not need to use shaping if you can get the behavior to occur by

telling or showing the person what to do
