orward Chaining
Begin with the first SD- response component in the chain and then continue forward through the remaining SD-response
... [Show More] components.
Example: Teaching a child to brush their teeth from the beginning of the task with the SD "Brush your teeth" the child gets the tooth brush, turns on the cold water, puts the toothbrush under the water... eventually then gets towel, wipes mouth and hands and hangs towel up. The reinforcer will be AFTER THE TARGET STEP and the Therapist will continue to guide the child through the rest of the chain.
Discrimination Training
The process of reinforcing a target response only when the target antecedent or SD is present. Teaching the client to "tell the difference between two or more SDs."
Examples: Teaching the child to be able to tell the difference between their mom and dad in pictures with saying "Touch mom" or "Touch dad" and the child responds correctly. When holding up an apple teaching the child to answer the different questions of "What is it?" "What do you do with it?" and "What color is it?" using only the apple as the stimulus.
Simultaneous Discrimination Training
When multiple objects are placed in front of the child and they are asked to touch, point or pick up the item.
- This type has a visual field and most likely involves using a table and chair or sitting on the floor
- Uses 7 step and the 4 step sequence of teaching (refer to initial training notes)
- Examples of SDs that use this method: "Touch (color)", "Give me the (object)" "Point to the (item)"
Successive Discrimination Training
When the target and the distractors cannot be presented simultaneously. The target and the distractor occur across successive trials
- This type has NO visual field of stimuli.
- Uses 3 step and the 2 step sequence of teaching (refer to initial training notes)
- Examples of SDs that use this method: Telling the client to do an action like "Jump." (They cant do anything else at the same time) Asking the client a question like "What is your name?" (They cannot answer anything else at the same time)
Expanded trials
Systematically increasing the time in between presentation of the target Sd by gradually increasing the number of trials of previously mastered targets. The formula is as follows: TXdTXdTXdTXd, TXddTXddTXddTX, TXdddTXdddTXdddTX
Example: Target item: shoe Mastered items: cup and dog
For the TX above insert "shoe" for the d above insert "cup" or "dog" [Show Less]
