CHAPTER 11- CHAINING
Prompts are used to evoke a behavior and transfer of stimulus control is used to eliminate
the prompts and get the behavior to in the presence of the relevant discriminative stimulus
). Most often, these procedures are used to develop simple discriminations in which one
response occurs in the presence of one (S
-Example: A student reads a word correctly
1. You say thank you WHEN someone gives you something
Each of the above examples involves one behavior occurring in the correct situation.
However, many situations call for complex behaviors that have multiple component
-This is called behavioral chain
When you want a piece of chewing gum:
1. Reach into your pocket
2. Pull out the pack of gum
3. Pull a single stic k out of the pack
4. Unwrap the piece, and
5. Put the gum into your mouth.
You can only engage in a particular behavior in the sequence only if the previous behavior in
the sequence has been completed. You can’t put the gum in your mouth unless you have
taken it out of your pocket.
Analyzing Stimulus- Response Chains:
Each behavioral chain consists of a number of individual stimulus-response components that
occur together in a sequence. For this reason, a behavioral chain is often called a stimulus-
-Each behavior or response in the chain produces a stimulus change that acts as an
for the next response in the chain.
1. The first response produces an S
for the second response in the
sequence and so forth.
2. The whole-stimulus response chain is under stimulus control- so the first
response in the chain occurs when a particular S
oThe gum in your pocket is an S
for the first response in the chain-
reaching in your poc ket and grabbing the pack of gum.
2. A behavioral chain continues only if the last response in the chain results in a
oChewing the gum is a reinforcer for the behavioral chain of putting the
gum in your mouth.
The Process is described as follows:
